Solar power in India

Solar power is a fast developing industry in India.[1] The country's solar installed capacity was 70.01 GWAC as of 30 June 2023.[2] Solar power generation in India ranks fourth globally in 2021.[3]

2050 MW Pavagada Solar Park

In FY2023-24, India is planning to issue 40 GW tenders for solar and hybrid projects.[4] India has established nearly 42 solar parks to make land available to the promoters of solar plants.[5]

During 2010–19, the foreign capital invested in India on Solar power projects was nearly 20.7 billion US$.[6]

The International Solar Alliance (ISA), proposed by India as a founder member, is headquartered in India. India has also put forward the concept of "One Sun One World One Grid" and "World Solar Bank" to harness abundant solar power on a global scale.[7][8]

History Edit

The Indian Government had an initial target of 20 GW capacity for 2022, which was achieved four years ahead of schedule.[9] In 2015 the target was raised to 100 GW of solar capacity (including 40 GW from rooftop solar) by 2022, targeting an investment of US$100 billion.[10][11] The target was widely missed by 40,000 MW shortfall due to poor performance in rooftop sector.

Rooftop solar power accounts for 2.1 GW in 2018, of which 70% is industrial or commercial.[12] In addition to its large-scale grid-connected solar photovoltaic (PV) initiative, India is developing off-grid solar power for local energy needs.[13] Solar products have increasingly helped to meet rural needs; by the end of 2015 just under one million solar lanterns were sold in the country, reducing the need for kerosene.[14] That year, 118,700 solar home lighting systems were installed and 46,655 solar street lighting installations were provided under a national programme;[14] just over 1.4 million (1.4 million) solar cookers were distributed in India.[14]

Solar potential Edit

 
Photovoltaic Electricity Potential of India

With about 300 clear and sunny days in a year, the calculated solar energy incidence on India's land area is about 5,000 trillion kilowatt-hours (kWh) per year (or 5 EWh/yr).[15][16] The solar energy available in a single year exceeds the possible energy output of all of the fossil fuel energy reserves in India. The daily average solar-power-plant generation capacity in India is 0.30 kWh per m2 of used land area,[17] equivalent to 1,400–1,800 peak (rated) capacity operating hours in a year with available, commercially-proven technology.[18][19][20]

Solar radiation resource assessment stations (SRRA) in India. MNRE Phase1  , MNRE Phase2  , MEDA  , AMS  , ANERT   SRRA stations.[21]

In June 2015, India began a 40 crore (US$5.0 million) project to measure solar radiation with a spatial resolution of 3 by 3 kilometres (1.9 mi × 1.9 mi). This solar-radiation measuring network provides the basis for the Indian solar-radiation atlas. 121 solar radiation resource assessment (SRRA) stations have been installed across India by the National Institute of Wind Energy, Ministry of New and Renewable Energy to create a database of solar-energy potential. Data is collected and reported to the Centre for Wind Energy Technology (C-WET). Among the parameters measured are Global Horizontal Irradiance (GHI), Direct Normal Irradiance (DNI) and Diffuse Horizontal Irradiance (DHI).[22][21][23]

Andhra Pradesh Edit

The installed photovoltaic capacity in Andhra Pradesh was 4257 MW as of 30 September 2022.[32] The state is planning to add 10,050 MW solar power capacity to provide power supply to the farming sector during the day time.[33][34] The state has also offered five Ultra Mega Solar Power Projects with a total capacity of 12,200 MW to developers under renewable power export policy outside the state.[35][36][37][38][39] Andhra Pradesh is endowed with abundant pumped hydroelectric energy storage to make available solar power[40] in to round the clock power supply for meeting its ultimate energy needs.[41][42][43] The state is planning to construct 33,000 MW pumped storage projects to mitigate the intermittency associated with renewable energy.[44]

In 2015, NTPC agreed with APTransCo to install the 250-MW NP Kunta Ultra Mega Solar Power Project near Kadiri in Anantapur district.[45][46] In October 2017, 1000 MW was commissioned at Kurnool Ultra Mega Solar Park which has become the world's largest solar power plant at that time.[47] In August 2018, Greater Visakhapatnam commissioned a 2 MW Mudasarlova Reservoir grid-connected floating solar project which is the largest operational floating solar PV project in India.[48] NTPC Simhadri has awarded BHEL to install a 25 MW floating solar PV plant on its water supply reservoir.[49] APGENCO commissioned 400 MW Ananthapuram – II solar park located at Talaricheruvu village near Tadipatri.[50]

Delhi Edit

Delhi being the Capital and a city state in India, has limitation in installing ground based solar power plants. However it is leading in rooftop solar powered plants installations by adopting fully flexible net metering system.[51] The installed solar power capacity is 211 MW as on 30 June 2022. Delhi government has announced that the Rajghat thermal power plant will be officially shut at the 45 acre plant site and turned into a 5 MW solar power PV plant.

Gujarat Edit

Gujarat is one of India's most solar-developed states, with its total installed solar power generation capacity reaching 7,806 MW as of 30 June 2022.[52] Gujarat has been a leader in solar-power generation in India due to its high solar-power potential, availability of vacant land, connectivity, transmission and distribution infrastructure and utilities. According to a report by the Low Emission Development Strategies Global Partnership (LEDS GP) report, these attributes are complemented by political will and investment.[full citation needed] The 2009 Solar Power of Gujarat policy framework, financing mechanism and incentives have contributed to a green investment climate in the state and the targets for grid-connected solar power.[53][54]

The state has commissioned Asia's largest solar park near the village of Charanka in Patan district, the Gujarat Solar Park-1.[55] The park is generating 345 MW by March 2016 of its 500 MW total planned capacity and has been cited as an innovative and environmentally-friendly project by the Confederation of Indian Industry.In December 2018,[56] 700 MW Solar PV plant at Raghanesda Solar Park is contracted at ₹2.89/unit levelised tariff.[57]

To make Gandhinagar a solar-power city, the state government has begun a rooftop solar-power generation scheme. Under the scheme, Gujarat plans to generate 5 MW of solar power by putting solar panels on about 50 state-government buildings and 500 private buildings.

It also plans to generate solar power by putting solar panels along the Narmada irrigation canals. As part of this scheme, the state has commissioned the 1 MW Canal Solar Power Project on a branch of the Narmada Canal near the village of Chandrasan in Mehsana district. The pilot project is expected to stop 90,000 litres (24,000 US gal; 20,000 imp gal) of water per year from evaporating from the Narmada River.

In March 2022, Surat based Diamond Merchant Govind Dholakia aka Govind Kaka made his native in Amreli's Dudhala Complete Solarization. A 450 KW Solar Rooftop project will be used to power around 350 houses and public areas such as anganwadis and gram panchayat. Once complete, this would be the first village to be completely powered with solar panels by a Charitable trust or Foundation. Under the mentorship of Govind Dholakia who is the founder of SRKKF and his sole thought behind this initiative is to give it back to the society.[58][59]

Haryana Edit

State has set the 4.2 GW solar power (including 1.6 GW solar roof top) target by 2022 as it has high potential since it has at least 330 sunny days. Haryana is one of the fastest growing state in terms of solar energy with installed and commissioned capacity of 73.27 MW. Out of this, 57.88 MW was commissioned in FY 2016/17. Haryana solar power policy announced in 2016 offers 90% subsidy to farmers for the solar powered water pumps, which also offers subsidy for the solar street lighting, home lighting solutions, solar water heating schemes, solar cooker schemes. It is mandatory for new residential buildings larger than 500 square yards (420 m2) to install 3% to 5% solar capacity for no building plan sanctioning is required, and a loan of up to ₹1 million is made available to the residential property owners. Haryana provides 100% waiver of electricity taxes, cess, electricity duty, wheeling charges, cross subsidy charges, transmission and distribution charges, etc. for rooftop solar projects.

In December 2018, Haryana had installed solar capacity of 48.80 MW,[60] and in January 2019 Haryana floated tender for 300 MW grid-connected solar power,[61] and additional 16 MW tender for the canal top solar power.[62]

Karnataka Edit

Karnataka is one of the highest solar power producing state in India with a total 7,597 MW installed capacity by the end of June 2022.[63] The installed capacity of Pavagada Solar Park is 2050 MW by the end of year 2019 which was the world biggest solar park at that time.[64]

Kerala Edit

The installed capacity of solar plants in Kerala as on 31 March 2023 is 761 MW.[30] Kochi international airport is the first airport to run completely in solar energy. CIAL solar farm is responsible for it. There are plans to setup solar power plants in Idukki, Wayanad, Malappuram and Palakkad districts.

The first solar park in Kerala is located in Perla, Kasaragod Perla, Kasaragod. Floating Solar parks are being built and partly functional in Banasura Sagar, Idukki Dam and Vembanad Lake.

The installed capacity is generally given in DC capacity at standard operating conditions.[88] The actual AC power peak output at high voltage from a solar plant is between 65 and 75% of the rated DC capacity, after accounting for temperature coefficient, derating of solar cells capacity with time, losses in the total system, elevation of the plant, location of the plant, actual solar irradiance, etc.[89] The AC peak power is also generally limited by the selected inverter's capacity for economic reasons.

As of September 2022, the rooftop solar power generation capacity is 8.3 GW.[90] Rooftop solar can be divided into residential solar, commercial and industrial solar roofs as well as a range of installations including agricultural buildings, community and cultural centers. 70 per cent of rooftop solar in 2018 was in the industrial and commercial sectors, with just 20 per cent as residential rooftop solar.[12] Rooftop solar as a proportion of total solar installations is much less than is typical in other leading solar countries but was forecast to grow to 40 GW by 2022 under national targets.[11] A rough calculation would imply that India had around just 430 MW of residential rooftop solar, whilst the UK with around half the overall solar capacity of India had over 2,500 MW of residential solar in 2018. The smallest segment was off-grid solar at 1467 MW which could help play a role in reaching villages and dwellings without access to the national grid.

The open-access solar installation capacity reached 7.0 GW capacity as of September 2022.[91]

Concentrated solar power Edit

The installed capacity of commercial concentrated solar power plants (non-storage type) in India is 227.5 MW with 50 MW in Andhra Pradesh and 177.5 MW in Rajasthan.[92] The existing solar thermal power plants (non-storage type) in India, which are generating costly intermittent power on a daily basis, can be converted into storage type solar thermal plants to generate 3 to 4 times more base load power at cheaper cost and not depend on government subsidies.[93] In March 2020, SECI called for 5000 MW tenders which can be combination of solar PV with battery storage, solar thermal with thermal energy storage (including biomass firing as supplementary fuel) and coal based power (minimum 51% from renewable sources) to supply round the clock power at minimum 80% yearly availability.[94]

Hybrid solar plants Edit

Solar power, generated mainly during the daytime in the non-monsoon period, complements wind which generate power during the monsoon months in India.[95][96] Solar panels can be located in the space between the towers of wind power plants.[97] It also complements hydroelectricity, generated primarily during India's monsoon months. Solar-power plants can be installed near existing hydropower and pumped-storage hydroelectricity, using the existing power transmission infrastructure and storing the surplus secondary power generated by the solar PV plants.[98][99] Floating solar plants on the reservoirs of pumped-storage hydroelectric plants are complementary to each other.[100] Solar PV plants clubbed with pumped-storage hydroelectric plants are also under construction to supply peaking power.[101]

During the daytime, the additional auxiliary power consumption of a solar thermal storage power plant is nearly 10% of its rated capacity for the process of extracting solar energy in the form of thermal energy.[102] This auxiliary power requirement can be made available from cheaper solar PV plant by envisaging hybrid solar plant with a mix of solar thermal and solar PV plants at a site. Also to optimise the cost of power, generation can be from the cheaper solar PV plant (33% generation) during the daylight whereas the rest of the time in a day is from the solar thermal storage plant (67% generation from solar power tower and parabolic trough types) for meeting 24 hours baseload power.[103] When solar thermal storage plant is forced to idle due to lack of sunlight locally during cloudy days in monsoon season, it is also possible to consume (similar to a lesser efficient, huge capacity and low cost battery storage system) the cheap excess grid power when the grid frequency is above 50 hz for heating the hot molten salt to higher temperature for converting stored thermal energy in to electricity during the peak demand hours when the electricity sale price is profitable.[104][105][106]

Solar heating Edit

Generating hot water or air or steam using concentrated solar reflectors, is increasing rapidly. Presently concentrated solar thermal installation base for heating applications is about 20 MWth in India and expected to grow rapidly.[107][108] Cogeneration of steam and power round the clock is also feasible with concentrated solar power CHP plants with thermal storage capacity.[citation needed]

Bengaluru has the largest deployment of roof-top solar water heaters in India, generating an energy equivalent of 200 MW.[109] It is India's first city to provide a rebate of 50 (63¢ US) on monthly electricity bills for residents using roof-top thermal systems,[110] which are now mandatory in all new structures. Pune has also made solar water heaters mandatory in new buildings.[111] Photovoltaic thermal (PVT) panels produce simultaneously the required warm water/air along with electricity under sunlight.[112]

Rural electrification Edit

The lack of an electricity infrastructure is a hurdle to rural India's development. India's power grid is under-developed, with large groups of people still living off the grid.[113] In 2004, about 80,000 of the nation's villages still did not have electricity, 18,000 out of them could not be electrified by extending the conventional grid due to inconvenience. A target of electrifying 5,000 such villages was set for the 2002–2007 Five-Year Plan. By 2004 more than 2,700 villages and hamlets were electrified, primarily with solar photovoltaic systems.[15] The development of inexpensive solar technology is considered a potential alternative, providing an electricity infrastructure consisting of a network of local-grid clusters with distributed electricity generation.[114] It could bypass (or relieve) expensive, long-distance, centralised power-delivery systems, bringing inexpensive electricity to large groups of people.[115] In Rajasthan during Financial Year 2016–17, 91 villages have been electrified with a solar standalone system and over 6,200 households have received a 100W solar home-lighting system.[citation needed]

India has sold or distributed about 1.2 million solar home-lighting systems and 3.2 million solar lanterns, and has been ranked the top Asian market for solar off-grid products.[116][117]

Lamps and lighting Edit

By 2012, a total of 4,600,000 solar lanterns and 861,654 solar-powered home lights were installed. Typically replacing kerosene lamps, they can be purchased for the cost of a few months' worth of kerosene with a small loan. The Ministry of New and Renewable Energy is offering a 30- to 40-percent subsidy of the cost of lanterns, home lights and small systems (up to 210 Wp).[118] Twenty million solar lamps are expected by 2022.[119]

Agricultural support Edit

Solar photovoltaic water-pumping systems are used for irrigation and drinking water.[120] Most pumps are fitted with a 200–3,000 W (0.27–4.02 hp) motor powered with a 1,800 Wp PV array which can deliver about 140,000 litres (37,000 US gal) of water per day from a total hydraulic head of 10 m (33 ft). By 31 October 2019 a total of 181,521 solar photovoltaic water pumping systems were installed and total solar photovoltaic water pumping systems would reach 3.5 million by the year 2022 under PM KUSUM scheme.[121][122][123] During hot sunny daytime when the water needs are more for watering the fields, solar pumps performance can be improved by maintaining pumped water flowing/sliding over the solar panels to keep them cooler and clean.[124] Agro photovoltaics is the electricity generation without losing agriculture production by using the same land.[125][126] Solar driers are used to dry harvests for storage.[127] Low cost solar powered bicycles are also available to ply between fields and village for agricultural activity, etc.[128][129] On site/field, fertiliser is produced from air by solar power with no carbon emissions.[130]

Rainwater harvesting Edit

In addition to solar energy, rainwater is a major renewable resource of any area. In India, large areas are being covered by solar PV panels every year. Solar panels can also be used for harvesting most of the rainwater falling on them and drinking or breweries water quality, free from bacteria and suspended matter, can be generated by simple filtration and disinfection processes, as rainwater is very low in salinity.[131][132] Good quality water resources, closer to populated areas, are becoming a scarcity and increasingly costly for consumers. Exploitation of rainwater for value-added products like bottled drinking water makes solar PV power plants profitable even in high rainfall and cloudy areas by the increased income from drinking water generation.[133]

Refrigeration and air conditioning Edit

Residential electricity consumers who are paying higher slab rates more than 5 (6.3¢ US) per unit, can form into local groups to install collectively rooftop off-grid solar power units (without much battery storage) and replace the costly power used from the grid with the solar power as and when produced.[134] Hence power draw from the grid which is an assured power supply without much power cuts nowadays, serves as a cheaper backup source when grid power consumption is limited to lower slab rate by using solar power during the day time. The maximum power generation of solar panels during the sunny daytime is complementary with the enhanced residential electricity consumption during the hot/summer days due to the higher use of cooling appliances such as fans, refrigerators, air conditioners, desert coolers, water heaters, etc.[135] It would discourage Discoms to extract higher electricity charges selectively from its consumers.[136] There is no need of any permission from Discoms similar to DG power sets installation. Cheaper discarded batteries of electric vehicle can also be used economically to store the excess solar power generated in the daylight.[137][138]

Maximum solar-electricity generation during the hot hours of the day can be used for meeting residential air-conditioning requirements regardless of other load requirements, such as refrigeration, lighting, cooking, and water pumping. Power generation of photovoltaic modules can be increased by 17 to 20 per cent by equipping them with a tracking system.[139][140]

In regions where peak electricity demand occurs in the evening, precooling of houses by increasing A/C settings in the afternoon as well as air conditioning systems combined with chilled water storage can increase the value of PV to the system and facilitate high shares of PV in total electricity generation.[141] Using both options to better match AC electricity demand with PV electricity supply could increase cost-optimal shares of PV in total electricity by up to 15 percentage points.[141]

Grid stabilisation Edit

Solar power PV plants are capable to provide fast frequency response in ramping up falling grid frequency.[142] Solar-power plants equipped with battery storage systems where net energy metering is used can feed stored electricity into the power grid when its frequency is below the rated parameter (50 Hz) and draw excess power from the grid when its frequency is above the rated parameter.[143][144] Excursions above and below the rated grid frequency occur about 100 times daily.[145][146] The solar-plant owner would receive nearly double the price for electricity sent into the grid compared to that consumed from the grid if a frequency-based tariff is offered to rooftop solar plants or plants dedicated to a distribution substation.[147][148] A power-purchase agreement (PPA) is not needed for solar plants with a battery storage systems to serve ancillary-service operations and transmit generated electricity for captive consumption using an open-access facility.[149][150] Battery storage is popular in India, with more than 10 million households using battery backup during load shedding.[151] Battery storage systems are also used to improve the power factor.[152] Solar PV or wind paired with four-hour battery storage systems is already cost competitive, without subsidy and power purchase agreement by selling peak power in Indian Energy Exchange, as a source of dispatchable generation compared with new coal and new gas plants in India".[153][154] Battery energy storage system cost have come down drastically in India for a mega storage capacity of 500 MW with four hours daily power supply (two round trip cycles per day) at full capacity.[155][156]

India is experiencing morning peak power demand for nearly 6 months from November to April and the solar power generation from 6 am to 10 am is not adequate to meet morning peak demand as its availability peaks at midday time. However solar power panels can be oriented/fixed towards the south-eastern direction (nearly 10° towards the east from the south direction) to capture more sunlight for enhanced solar power generation during peak hours.[157] Higher solar tariffs during morning hours enable the solar power plants to cater the maximum peak demand of the national grid reducing the load on peaking hydropower or load-following power plants.[158][125]

Battery storage is also used economically to reduce daily/monthly peak power demand for minimising the monthly demand charges from the utility to the commercial and industrial establishments.[159] Using batteries to shift PV electricity from times with very high generation (noon) to times with low generation (evening, night, morning) can increase the cost-optimal share of PV in the future Indian power system substantially, from 40 to 50% without batteries to 60–90% with batteries.[160]

Challenges and opportunities Edit

The land price is costly for acquisition in India.[161] Dedication of land for the installation of solar arrays must compete with other needs.[162] The amount of land required for utility-scale solar power plants is about 1 km2 (250 acres) for every 40–60 MW generated. One alternative is to use the water-surface area on canals, lakes, reservoirs, farm ponds and the sea for large solar-power plants.[163][164][165] Due to better cooling of the solar panels and the sun tracking system, the output of solar panels is enhanced substantially.[166] These water bodies can also provide water to clean the solar panels.[167] Floating solar plants installation cost has reduced steeply by 2018.[168] In January 2019, Indian Railways announced the plan to install 4 GW capacity along its tracks.[169][170] Highways and railways may also avoid the cost of land nearer to load centers, minimizing transmission-line costs by having solar plants about 10 meters above the roads or rail tracks.[171][172] Solar power generated by road areas may also be used for in-motion charging of electric vehicles, reducing fuel costs.[173] Highways would avoid damage from rain and summer heat, increasing comfort for commuters.[174][175][176] By using high efficiency monocrystalline silicon modules in an earth mount solar array, the cost of module supporting structures and the land requirement are reduced drastically without reduction in electricity generation.[177] Earth mounted solar arrays can withstand category 4 hurricane and designed for water submergence condition.[178][179] To reduce land footprint drastically where land cost is high, vertical installation of solar panels forming a solar tower is also feasible.[180] The installed length of transmission lines of 66 kV and above is 649,833 km (403,788 mi) with nearly 2 million truss type transmission towers.[181] These transmission towers have nearly 50 GW solar PV potential (without any extra land footprint) @ 25 kW/tower if panels are installed on the south-facing facade at a safe distance from the conductors.[182] Using micro-inverters for each solar panel would minimize the effect of shading that is caused for some duration by the transmission tower.[183]

The architecture best suited to most of India would be a set of rooftop power-generation systems connected via a local grid.[184] Not only the rooftop area but also outer surface area of tall buildings can be used for solar PV power generation by installing PV modules in a vertical position in place of glass panels to cover facade area.[185] Such an infrastructure, which does not have the economy of scale of mass, utility-scale solar-panel deployment, needs a lower deployment price to attract individuals and family-sized households.[186] The cost of high efficiency and compact mono PERC modules and battery storage systems have reduced to make rooftop solar PV more economical and feasible in a microgrid.[187][138][188]

It is more economical to have multi-purpose floating solar PV power plants compared to single-purpose floating solar plants.[189] Three tier boat houses are constructed on pontoons with the top tier (inclined roof up to 35 degrees) fully covered by solar panels (1 MW/acre area), bottom area (below the pontoon) for cage fish culture and middle two tiers one each for poultry and mushroom/orchid cultivation. Pontoon can have a tilting arrangement (another 35 degrees) to have inclined floating by varying water content in the ballast tanks to track the sun's direction for optimum solar power generation. Water is oxygenated in a evaporative cooler and used in cage cultivation with the power generated by the solar panels. The cold air at wet-bulb temperature from the evaporative cooler is used for cooling the poultry and mushroom areas. These boathouses can move to safer water depths with the variation in the water level of the water body or for avoiding occasional high winds. The excess power generated during the daytime is stored in a battery system mounted on a separate pontoon which can be moved to shore for feeding power to the grid during nighttime.[190][191] Multipurpose solar plants can be installed at deeper (10 meters and more) water areas, unlike single-purpose floating solar PV plants.[192] With multipurpose PV solar plants, the floating solar power potential of India enhances many times by using much of the inland water bodies area.[193] Water is sprinkled over the solar panels to keep them cool and clean to optimize the power output. Rainwater harvesting can also be achieved by storing the water in collapsible bladders which can float on water for generating bottled drinking water.

Greenpeace[15][194][195] recommends that India adopt a policy of developing solar power as a dominant component of its renewable-energy mix since, being a densely-populated country[196] in the tropical belt,[197][198] the subcontinent has an ideal combination of high insolation[197] and a large potential consumer base.[199][200][201] In one scenario[195] India could make renewable resources the backbone of its economy by 2030, curtailing carbon emissions without compromising its economic-growth potential. A study suggested that 100 GW of solar power could be generated through a mix of utility-scale and rooftop solar, with the realisable potential for rooftop solar between 57 and 76 GW by 2024.[202]

After the subsidence of the Covid pandemic in 2022, the electricity demand has increased steeply and spot/day ahead power sale prices are at upper ceiling price of 12 (15¢ US) per kWh round the clock.[citation needed]

It is considered prudent to encourage solar-plant installations up to a threshold (such as 7,000 MW) by offering incentives.[203] Otherwise, substandard equipment with overrated nameplate capacity may tarnish the industry.[204][205] The power purchaser, transmission agency and financial institution should require capacity utilisation and long-term performance guarantees for the equipment backed by insurance coverage in the event that the original equipment manufacturer ceases to exist.[206][207][208] Alarmed by the low quality of equipment, India issued draft quality guide lines in May 2017 to be followed by the solar plant equipment suppliers conforming to Indian standards.[209][210][211]

Government support Edit

The Indian government announced an allocation of 10 billion (US$130 million) for the National Solar Mission and a clean-energy fund for the 2010–11 fiscal year, an increase of 3.8 billion (US$48 million) from the previous budget. The budget encouraged private solar companies by reducing the import duty on solar panels by five per cent. This is expected to reduce the cost of a rooftop solar-panel installation by 15 to 20 per cent.

The Indian government is giving subsidies[212] for installing rooftop solar panels in an effort to increase the adoption of solar power in the country. Rooftop solar panels have numerous benefits, including the ability to generate electricity directly from the source, reducing dependence on fossil fuels, and lowering electricity bills for households and businesses. In addition, rooftop solar panels help to reduce carbon emissions, making them a key component in India's efforts to combat climate change. With the availability of government subsidies, more households and businesses can now afford to install rooftop solar panels, contributing to a more sustainable future for the country.

Solar PV tariff Edit

 
Price of silicon solar cells since 1977. The great thing about solar power is that it is a technology and not a fuel. It is unlimited and the more it is deployed the cheaper it would be.[187] While the more limited fossil fuels are used, the more expensive they become.[213][214]

The average bid in reverse auctions in April 2017 is 3.15 (3.9¢ US) per kWh, compared with 12.16 (15¢ US) per kWh in 2010, which is around 73% drop over the time window.[215][216][217] The current prices of solar PV electricity is around 18% lower than the average price of electricity generated by coal-fired plants.[218] By the end of 2018, competitive reverse auctions, falling panel and component prices, the introduction of solar parks, lower borrowing costs and large power companies have contributed to the fall in prices.[219] The cost of solar PV power in India, China, Brazil and 55 other emerging markets fell to about one-third of its 2010 price, making solar the cheapest form of renewable energy and cheaper than power generated from fossil fuels such as coal and gas.[220]

India has the lowest capital cost per MW globally of installing solar power plants.[221] However the global levelised cost of solar PV electricity fell to 1.04¢ US per kWh (₹0.77 per kWh) in April 2021, much cheaper than the lowest solar PV tariff in India.[222][223][224][225][226] The intermittent / non-dispatchable solar PV at the prevailing low tariffs clubbed with Pumped-heat electricity storage can offer cheapest dispatchable power round the clock on demand.

The Indian government has reduced the solar PV power purchase price from the maximum allowed 4.43 (5.5¢ US) per KWh to 4.00 (5.0¢ US) per KWh, reflecting the steep fall in cost of solar power-generation equipment.[227][228][229] The applicable tariff is offered after applying viability gap funding (VGF) or accelerated depreciation (AD) incentives.[230][231] In January 2019, the time period for commissioning the solar power plants is reduced to 18 months for units located outside the solar parks and 15 months for units located inside the solar parks from the date of power purchase agreement.[232]

Solar PV generation cost fell to 2.97 (3.7¢ US) per kWh for the 750 MW Rewa Ultra Mega Solar power project, India's lowest electricity-generation cost.[233][234] In first quarter of calendar year 2020, large scale ground mounted solar power installations cost fell to Rs 35 million/MW by 12% in a year.[235] Solar panel prices are lower than those of mirrors by unit area.[120][236]

In an auction of 250 MW capacity of the second phase in Bhadla solar park, South Africa's Phelan Energy Group and Avaada Power were awarded 50 MW and 100 MW of capacity respectively in May 2017 at 2.62 (3.3¢ US) per kilowatt hour.[237] The tariff is also lower than NTPC's average coal power tariff of 3.20 per kilowatt hour. SBG Cleantech, a consortium of SoftBank Group, Airtel and Foxconn, was awarded the remaining 100 MW capacity at a rate of 2.63 (3.3¢ US) per kWh.[238][239] Few days later in a second auction for another 500 MW at the same park, solar tariff has further fallen to 2.44 (3.1¢ US) per kilowatt hour which are the lowest tariffs for any solar power project in India.[240] These tariffs are lower than traded prices for day time in non-monsoon period in IEX and also for meeting peak loads on a daily basis by using cheaper solar PV power in pumped-storage hydroelectricity stations indicating there is no need of any power purchase agreements and any incentives for the solar PV power plants in India.[241][242][243] Solar PV power plant developers are forecasting that solar power tariff would drop to 1.5 (1.9¢ US) /unit in near future.[244][187]

The lowest solar tariff in May 2018 is Rs 2.71/kWh (without incentives) which is less than the tariff of Bhadla solar park (₹2.44 per kWh with VGF incentive) after the clarification that any additional taxes are pass through cost with hike in the tariff.[245][246] In early July 2018 bids, the lowest solar PV tariff has touched 2.44 (3.1¢ US) per kWh without viability gap funding incentive.[247][248] In June 2019, the lowest tariff is 2.50 (3.1¢ US)/kWh for feeding in to the high voltage interstate transmission system (ISTS).[249][250][251] In February 2019, the lowest solar power tariff is 1.24 (1.6¢ US) per kWh for 50 MW contracted capacity at Pavagada Solar Park.[252][253]

The tariff for rooftop installations is also falling with the recent offer of 3.64 (4.6¢ US) with 100% locally made components.[254] In August 2022, the installation cost of rooftop solar has reduced below 45,000 Rs/KW for capacity between 1 and 3 KW.[255]

In May 2020, the discovered first-year tariff is 2.90 (3.6¢ US) per kWh with 3.60 (4.5¢ US) per kWh levelised tariff for round-the-clock hybrid renewable power supply.[256] In November 2020, Solar PV power tariff has fallen to 2.00 (2.5¢ US) per kWh.[257][258]

In March 2021, the discovered levelised tariff was 2.20 (2.8¢ US) per kWh after the imposition of basic customs duty (BCD) on imported solar PV panels and cells.[259] The discovered tariff for floating solar power was 3.70 (4.6¢ US) per kWh in November 2022.[260]

In April 2023, the discovered minimum levelised tariff was 3.99 (5.0¢ US) per kWh for the round-the-clock hybrid solar power supply with or without storage.[261] In April 2023, the discovered minimum tariff for solar power was 2.55 (3.2¢ US) per kWh.[262]

Incentives Edit

At the end of July 2015, the chief incentives were:

  1. Viability Gap Funding: Under the reverse bidding process, bidders who need least viability gap funding at the reference tariff (RS 4.93 per unit in 2016) is selected.[263] Funding was ₹1 Crore/MW for open projects on average in 2016.
  2. Depreciation: For profit-making enterprises installing rooftop solar systems, 40 per cent of the total investment could be claimed as depreciation in the first year (decreasing taxes).
  3. Liberal external commercial borrowing facility for the solar power plants.[264]
  4. To protect the local solar panel manufacturers, 25% safe guard duty is imposed for two years period from August 2018 on the imports from China & Malaysia who are suspected of dumping solar panels in to India.[265]
  5. Capital subsidies were applicable to rooftop solar-power plants up to a maximum of 500 kW. The 30 per cent subsidy was reduced to 15 per cent.
  6. Renewable Energy Certificates (RECs): Tradeable certificates providing financial incentives for every unit of green power generated.[266]
  7. Net metering incentives depend on whether a net meter is installed and the utility's incentive policy. If so, financial incentives are available for the power generated.[267]
  8. Assured Power Purchase Agreement (PPA): The power-distribution and -purchase companies owned by state and central governments guarantee the purchase of solar PV power when produced only during daylight. The PPAs offer fair market determined tariff for the solar power which is a secondary power or negative load and an intermittent energy source on a daily basis.
  9. Interstate transmission system (ISTS) charges and losses are not levied during the period of PPA for the projects commissioned before 31 March 2022.[268]
  10. Union government offers 70% and 30% subsidy for the hill states and other states respectively for the installation of rooftop solar units.[12] Additional incentives are offered to rooftop solar power plants from various state governments.[269][270]
  11. 100% foreign direct investment (FDI) is automatically permitted, subject to the provisions of The Electricity Act, 2003, to install solar power plants.[271]

Indian initiative of International solar alliance Edit

In January 2016, Prime Minister Narendra Modi and French President François Hollande laid the foundation stone for the headquarters of the International Solar Alliance (ISA) in Gwal Pahari, Gurugram. The ISA will focus on promoting and developing solar energy and solar products for countries lying wholly or partially between the Tropic of Cancer and the Tropic of Capricorn. The alliance of over 120 countries was announced at the Paris COP21 climate summit.[272] One hope of the ISA is that wider deployment will reduce production and development costs, facilitating the increased deployment of solar technologies to poor and remote regions.[citation needed]

Solar-panel manufacturing in India Edit

As of November 2021, manufacturing capacity of solar cells and solar modules in India was 4.3 GW and 18 GW, respectively.[273] Nearly 80 per cent of solar-panel's weight is flat glass.[274] 100–150 tons of flat glass is used to manufacture a MW of solar panels. Low-iron flat or float glass is manufactured from soda ash and iron-free silica. Soda-ash manufacturing from common salt is an energy-intensive process unless it is extracted from soda lakes or glasswort cultivation in alkali soil. To increase installation of photovoltaic solar-power plants, the production of flat glass and its raw materials must expand commensurately to eliminate supply constraints or future imports.[275]

The Ministry of New and Renewable Energy (MNRE), India, has issued a memorandum to ensure the quality of solar cells and solar modules.[276][277] Compliance with the requisite specifications will grant manufacturers and their specific products an entry in the ALMM (Approved List of Models and Manufacturers.)[278][279][280] Indian manufacturers are gradually enhancing the production capacity of monocrystalline silicon PERC cells to supply better performing and enduring solar cells to local market.[188] India’s solar panel sector is expected to be self-sufficient by 2026.[281]

For utility-scale solar projects, top solar module suppliers in 2016–17 were: Waaree Energies Ltd., Trina Solar, JA Solar, Canadian Solar, Risen, and Hanwha.[282]

of solar cells capacity with time losses in the total system elevation of the plant location of the plant actual solar irradiance etc 89 The AC peak power is also generally limited by the selected inverter s capacity for economic reasons As of September 2022 the rooftop solar power generation capacity is 8 3 GW 90 Rooftop solar can be divided into residential solar commercial and industrial solar roofs as well as a range of installations including agricultural buildings community and cultural centers 70 per cent of rooftop solar in 2018 was in the industrial and commercial sectors with just 20 per cent as residential rooftop solar 12 Rooftop solar as a proportion of total solar installations is much less than is typical in other leading solar countries but was forecast to grow to 40 GW by 2022 under national targets 11 A rough calculation would imply that India had around just 430 MW of residential rooftop solar whilst the UK with around half the overall solar capacity of India had over 2 500 MW of residential solar in 2018 The smallest segment was off grid solar at 1467 MW which could help play a role in reaching villages and dwellings without access to the national grid The open access solar installation capacity reached 7 0 GW capacity as of September 2022 91 Concentrated solar power EditThe installed capacity of commercial concentrated solar power plants non storage type in India is 227 5 MW with 50 MW in Andhra Pradesh and 177 5 MW in Rajasthan 92 The existing solar thermal power plants non storage type in India which are generating costly intermittent power on a daily basis can be converted into storage type solar thermal plants to generate 3 to 4 times more base load power at cheaper cost and not depend on government subsidies 93 In March 2020 SECI called for 5000 MW tenders which can be combination of solar PV with battery storage solar thermal with thermal energy storage including biomass firing as supplementary fuel and coal based power minimum 51 from renewable sources to supply round the clock power at minimum 80 yearly availability 94 Hybrid solar plants EditSolar power generated mainly during the daytime in the non monsoon period complements wind which generate power during the monsoon months in India 95 96 Solar panels can be located in the space between the towers of wind power plants 97 It also complements hydroelectricity generated primarily during India s monsoon months Solar power plants can be installed near existing hydropower and pumped storage hydroelectricity using the existing power transmission infrastructure and storing the surplus secondary power generated by the solar PV plants 98 99 Floating solar plants on the reservoirs of pumped storage hydroelectric plants are complementary to each other 100 Solar PV plants clubbed with pumped storage hydroelectric plants are also under construction to supply peaking power 101 During the daytime the additional auxiliary power consumption of a solar thermal storage power plant is nearly 10 of its rated capacity for the process of extracting solar energy in the form of thermal energy 102 This auxiliary power requirement can be made available from cheaper solar PV plant by envisaging hybrid solar plant with a mix of solar thermal and solar PV plants at a site Also to optimise the cost of power generation can be from the cheaper solar PV plant 33 generation during the daylight whereas the rest of the time in a day is from the solar thermal storage plant 67 generation from solar power tower and parabolic trough types for meeting 24 hours baseload power 103 When solar thermal storage plant is forced to idle due to lack of sunlight locally during cloudy days in monsoon season it is also possible to consume similar to a lesser efficient huge capacity and low cost battery storage system the cheap excess grid power when the grid frequency is above 50 hz for heating the hot molten salt to higher temperature for converting stored thermal energy in to electricity during the peak demand hours when the electricity sale price is profitable 104 105 106 Solar heating Edit nbsp A solar heating plant in RajasthanSee also Solar thermal energy Generating hot water or air or steam using concentrated solar reflectors is increasing rapidly Presently concentrated solar thermal installation base for heating applications is about 20 MWth in India and expected to grow rapidly 107 108 Cogeneration of steam and power round the clock is also feasible with concentrated solar power CHP plants with thermal storage capacity citation needed Bengaluru has the largest deployment of roof top solar water heaters in India generating an energy equivalent of 200 MW 109 It is India s first city to provide a rebate of 50 63 US on monthly electricity bills for residents using roof top thermal systems 110 which are now mandatory in all new structures Pune has also made solar water heaters mandatory in new buildings 111 Photovoltaic thermal PVT panels produce simultaneously the required warm water air along with electricity under sunlight 112 Rural electrification EditThe lack of an electricity infrastructure is a hurdle to rural India s development India s power grid is under developed with large groups of people still living off the grid 113 In 2004 about 80 000 of the nation s villages still did not have electricity 18 000 out of them could not be electrified by extending the conventional grid due to inconvenience A target of electrifying 5 000 such villages was set for the 2002 2007 Five Year Plan By 2004 more than 2 700 villages and hamlets were electrified primarily with solar photovoltaic systems 15 The development of inexpensive solar technology is considered a potential alternative providing an electricity infrastructure consisting of a network of local grid clusters with distributed electricity generation 114 It could bypass or relieve expensive long distance centralised power delivery systems bringing inexpensive electricity to large groups of people 115 In Rajasthan during Financial Year 2016 17 91 villages have been electrified with a solar standalone system and over 6 200 households have received a 100W solar home lighting system citation needed India has sold or distributed about 1 2 million solar home lighting systems and 3 2 million solar lanterns and has been ranked the top Asian market for solar off grid products 116 117 Lamps and lighting Edit By 2012 a total of 4 600 000 solar lanterns and 861 654 solar powered home lights were installed Typically replacing kerosene lamps they can be purchased for the cost of a few months worth of kerosene with a small loan The Ministry of New and Renewable Energy is offering a 30 to 40 percent subsidy of the cost of lanterns home lights and small systems up to 210 Wp 118 Twenty million solar lamps are expected by 2022 119 Agricultural support Edit Solar photovoltaic water pumping systems are used for irrigation and drinking water 120 Most pumps are fitted with a 200 3 000 W 0 27 4 02 hp motor powered with a 1 800 Wp PV array which can deliver about 140 000 litres 37 000 US gal of water per day from a total hydraulic head of 10 m 33 ft By 31 October 2019 a total of 181 521 solar photovoltaic water pumping systems were installed and total solar photovoltaic water pumping systems would reach 3 5 million by the year 2022 under PM KUSUM scheme 121 122 123 During hot sunny daytime when the water needs are more for watering the fields solar pumps performance can be improved by maintaining pumped water flowing sliding over the solar panels to keep them cooler and clean 124 Agro photovoltaics is the electricity generation without losing agriculture production by using the same land 125 126 Solar driers are used to dry harvests for storage 127 Low cost solar powered bicycles are also available to ply between fields and village for agricultural activity etc 128 129 On site field fertiliser is produced from air by solar power with no carbon emissions 130 Rainwater harvesting Edit In addition to solar energy rainwater is a major renewable resource of any area In India large areas are being covered by solar PV panels every year Solar panels can also be used for harvesting most of the rainwater falling on them and drinking or breweries water quality free from bacteria and suspended matter can be generated by simple filtration and disinfection processes as rainwater is very low in salinity 131 132 Good quality water resources closer to populated areas are becoming a scarcity and increasingly costly for consumers Exploitation of rainwater for value added products like bottled drinking water makes solar PV power plants profitable even in high rainfall and cloudy areas by the increased income from drinking water generation 133 Refrigeration and air conditioning Edit nbsp 4 MW horizontal single axis tracker in Vellakoil Tamil NaduResidential electricity consumers who are paying higher slab rates more than 5 6 3 US per unit can form into local groups to install collectively rooftop off grid solar power units without much battery storage and replace the costly power used from the grid with the solar power as and when produced 134 Hence power draw from the grid which is an assured power supply without much power cuts nowadays serves as a cheaper backup source when grid power consumption is limited to lower slab rate by using solar power during the day time The maximum power generation of solar panels during the sunny daytime is complementary with the enhanced residential electricity consumption during the hot summer days due to the higher use of cooling appliances such as fans refrigerators air conditioners desert coolers water heaters etc 135 It would discourage Discoms to extract higher electricity charges selectively from its consumers 136 There is no need of any permission from Discoms similar to DG power sets installation Cheaper discarded batteries of electric vehicle can also be used economically to store the excess solar power generated in the daylight 137 138 Maximum solar electricity generation during the hot hours of the day can be used for meeting residential air conditioning requirements regardless of other load requirements such as refrigeration lighting cooking and water pumping Power generation of photovoltaic modules can be increased by 17 to 20 per cent by equipping them with a tracking system 139 140 In regions where peak electricity demand occurs in the evening precooling of houses by increasing A C settings in the afternoon as well as air conditioning systems combined with chilled water storage can increase the value of PV to the system and facilitate high shares of PV in total electricity generation 141 Using both options to better match AC electricity demand with PV electricity supply could increase cost optimal shares of PV in total electricity by up to 15 percentage points 141 Grid stabilisation EditSolar power PV plants are capable to provide fast frequency response in ramping up falling grid frequency 142 Solar power plants equipped with battery storage systems where net energy metering is used can feed stored electricity into the power grid when its frequency is below the rated parameter 50 Hz and draw excess power from the grid when its frequency is above the rated parameter 143 144 Excursions above and below the rated grid frequency occur about 100 times daily 145 146 The solar plant owner would receive nearly double the price for electricity sent into the grid compared to that consumed from the grid if a frequency based tariff is offered to rooftop solar plants or plants dedicated to a distribution substation 147 148 A power purchase agreement PPA is not needed for solar plants with a battery storage systems to serve ancillary service operations and transmit generated electricity for captive consumption using an open access facility 149 150 Battery storage is popular in India with more than 10 million households using battery backup during load shedding 151 Battery storage systems are also used to improve the power factor 152 Solar PV or wind paired with four hour battery storage systems is already cost competitive without subsidy and power purchase agreement by selling peak power in Indian Energy Exchange as a source of dispatchable generation compared with new coal and new gas plants in India 153 154 Battery energy storage system cost have come down drastically in India for a mega storage capacity of 500 MW with four hours daily power supply two round trip cycles per day at full capacity 155 156 India is experiencing morning peak power demand for nearly 6 months from November to April and the solar power generation from 6 am to 10 am is not adequate to meet morning peak demand as its availability peaks at midday time However solar power panels can be oriented fixed towards the south eastern direction nearly 10 towards the east from the south direction to capture more sunlight for enhanced solar power generation during peak hours 157 Higher solar tariffs during morning hours enable the solar power plants to cater the maximum peak demand of the national grid reducing the load on peaking hydropower or load following power plants 158 125 Battery storage is also used economically to reduce daily monthly peak power demand for minimising the monthly demand charges from the utility to the commercial and industrial establishments 159 Using batteries to shift PV electricity from times with very high generation noon to times with low generation evening night morning can increase the cost optimal share of PV in the future Indian power system substantially from 40 to 50 without batteries to 60 90 with batteries 160 Challenges and opportunities EditSee also Energy policy of India Solar energy The land price is costly for acquisition in India 161 Dedication of land for the installation of solar arrays must compete with other needs 162 The amount of land required for utility scale solar power plants is about 1 km2 250 acres for every 40 60 MW generated One alternative is to use the water surface area on canals lakes reservoirs farm ponds and the sea for large solar power plants 163 164 165 Due to better cooling of the solar panels and the sun tracking system the output of solar panels is enhanced substantially 166 These water bodies can also provide water to clean the solar panels 167 Floating solar plants installation cost has reduced steeply by 2018 168 In January 2019 Indian Railways announced the plan to install 4 GW capacity along its tracks 169 170 Highways and railways may also avoid the cost of land nearer to load centers minimizing transmission line costs by having solar plants about 10 meters above the roads or rail tracks 171 172 Solar power generated by road areas may also be used for in motion charging of electric vehicles reducing fuel costs 173 Highways would avoid damage from rain and summer heat increasing comfort for commuters 174 175 176 By using high efficiency monocrystalline silicon modules in an earth mount solar array the cost of module supporting structures and the land requirement are reduced drastically without reduction in electricity generation 177 Earth mounted solar arrays can withstand category 4 hurricane and designed for water submergence condition 178 179 To reduce land footprint drastically where land cost is high vertical installation of solar panels forming a solar tower is also feasible 180 The installed length of transmission lines of 66 kV and above is 649 833 km 403 788 mi with nearly 2 million truss type transmission towers 181 These transmission towers have nearly 50 GW solar PV potential without any extra land footprint 25 kW tower if panels are installed on the south facing facade at a safe distance from the conductors 182 Using micro inverters for each solar panel would minimize the effect of shading that is caused for some duration by the transmission tower 183 The architecture best suited to most of India would be a set of rooftop power generation systems connected via a local grid 184 Not only the rooftop area but also outer surface area of tall buildings can be used for solar PV power generation by installing PV modules in a vertical position in place of glass panels to cover facade area 185 Such an infrastructure which does not have the economy of scale of mass utility scale solar panel deployment needs a lower deployment price to attract individuals and family sized households 186 The cost of high efficiency and compact mono PERC modules and battery storage systems have reduced to make rooftop solar PV more economical and feasible in a microgrid 187 138 188 It is more economical to have multi purpose floating solar PV power plants compared to single purpose floating solar plants 189 Three tier boat houses are constructed on pontoons with the top tier inclined roof up to 35 degrees fully covered by solar panels 1 MW acre area bottom area below the pontoon for cage fish culture and middle two tiers one each for poultry and mushroom orchid cultivation Pontoon can have a tilting arrangement another 35 degrees to have inclined floating by varying water content in the ballast tanks to track the sun s direction for optimum solar power generation Water is oxygenated in a evaporative cooler and used in cage cultivation with the power generated by the solar panels The cold air at wet bulb temperature from the evaporative cooler is used for cooling the poultry and mushroom areas These boathouses can move to safer water depths with the variation in the water level of the water body or for avoiding occasional high winds The excess power generated during the daytime is stored in a battery system mounted on a separate pontoon which can be moved to shore for feeding power to the grid during nighttime 190 191 Multipurpose solar plants can be installed at deeper 10 meters and more water areas unlike single purpose floating solar PV plants 192 With multipurpose PV solar plants the floating solar power potential of India enhances many times by using much of the inland water bodies area 193 Water is sprinkled over the solar panels to keep them cool and clean to optimize the power output Rainwater harvesting can also be achieved by storing the water in collapsible bladders which can float on water for generating bottled drinking water Greenpeace 15 194 195 recommends that India adopt a policy of developing solar power as a dominant component of its renewable energy mix since being a densely populated country 196 in the tropical belt 197 198 the subcontinent has an ideal combination of high insolation 197 and a large potential consumer base 199 200 201 In one scenario 195 India could make renewable resources the backbone of its economy by 2030 curtailing carbon emissions without compromising its economic growth potential A study suggested that 100 GW of solar power could be generated through a mix of utility scale and rooftop solar with the realisable potential for rooftop solar between 57 and 76 GW by 2024 202 After the subsidence of the Covid pandemic in 2022 the electricity demand has increased steeply and spot day ahead power sale prices are at upper ceiling price of 12 15 US per kWh round the clock citation needed It is considered prudent to encourage solar plant installations up to a threshold such as 7 000 MW by offering incentives 203 Otherwise substandard equipment with overrated nameplate capacity may tarnish the industry 204 205 The power purchaser transmission agency and financial institution should require capacity utilisation and long term performance guarantees for the equipment backed by insurance coverage in the event that the original equipment manufacturer ceases to exist 206 207 208 Alarmed by the low quality of equipment India issued draft quality guide lines in May 2017 to be followed by the solar plant equipment suppliers conforming to Indian standards 209 210 211 Government support EditThe Indian government announced an allocation of 10 billion US 130 million for the National Solar Mission and a clean energy fund for the 2010 11 fiscal year an increase of 3 8 billion US 48 million from the previous budget The budget encouraged private solar companies by reducing the import duty on solar panels by five per cent This is expected to reduce the cost of a rooftop solar panel installation by 15 to 20 per cent The Indian government is giving subsidies 212 for installing rooftop solar panels in an effort to increase the adoption of solar power in the country Rooftop solar panels have numerous benefits including the ability to generate electricity directly from the source reducing dependence on fossil fuels and lowering electricity bills for households and businesses In addition rooftop solar panels help to reduce carbon emissions making them a key component in India s efforts to combat climate change With the availability of government subsidies more households and businesses can now afford to install rooftop solar panels contributing to a more sustainable future for the country Solar PV tariff Edit nbsp Price of silicon solar cells since 1977 The great thing about solar power is that it is a technology and not a fuel It is unlimited and the more it is deployed the cheaper it would be 187 While the more limited fossil fuels are used the more expensive they become 213 214 The average bid in reverse auctions in April 2017 is 3 15 3 9 US per kWh compared with 12 16 15 US per kWh in 2010 which is around 73 drop over the time window 215 216 217 The current prices of solar PV electricity is around 18 lower than the average price of electricity generated by coal fired plants 218 By the end of 2018 competitive reverse auctions falling panel and component prices the introduction of solar parks lower borrowing costs and large power companies have contributed to the fall in prices 219 The cost of solar PV power in India China Brazil and 55 other emerging markets fell to about one third of its 2010 price making solar the cheapest form of renewable energy and cheaper than power generated from fossil fuels such as coal and gas 220 India has the lowest capital cost per MW globally of installing solar power plants 221 However the global levelised cost of solar PV electricity fell to 1 04 US per kWh 0 77 per kWh in April 2021 much cheaper than the lowest solar PV tariff in India 222 223 224 225 226 The intermittent non dispatchable solar PV at the prevailing low tariffs clubbed with Pumped heat electricity storage can offer cheapest dispatchable power round the clock on demand The Indian government has reduced the solar PV power purchase price from the maximum allowed 4 43 5 5 US per KWh to 4 00 5 0 US per KWh reflecting the steep fall in cost of solar power generation equipment 227 228 229 The applicable tariff is offered after applying viability gap funding VGF or accelerated depreciation AD incentives 230 231 In January 2019 the time period for commissioning the solar power plants is reduced to 18 months for units located outside the solar parks and 15 months for units located inside the solar parks from the date of power purchase agreement 232 Solar PV generation cost fell to 2 97 3 7 US per kWh for the 750 MW Rewa Ultra Mega Solar power project India s lowest electricity generation cost 233 234 In first quarter of calendar year 2020 large scale ground mounted solar power installations cost fell to Rs 35 million MW by 12 in a year 235 Solar panel prices are lower than those of mirrors by unit area 120 236 In an auction of 250 MW capacity of the second phase in Bhadla solar park South Africa s Phelan Energy Group and Avaada Power were awarded 50 MW and 100 MW of capacity respectively in May 2017 at 2 62 3 3 US per kilowatt hour 237 The tariff is also lower than NTPC s average coal power tariff of 3 20 per kilowatt hour SBG Cleantech a consortium of SoftBank Group Airtel and Foxconn was awarded the remaining 100 MW capacity at a rate of 2 63 3 3 US per kWh 238 239 Few days later in a second auction for another 500 MW at the same park solar tariff has further fallen to 2 44 3 1 US per kilowatt hour which are the lowest tariffs for any solar power project in India 240 These tariffs are lower than traded prices for day time in non monsoon period in IEX and also for meeting peak loads on a daily basis by using cheaper solar PV power in pumped storage hydroelectricity stations indicating there is no need of any power purchase agreements and any incentives for the solar PV power plants in India 241 242 243 Solar PV power plant developers are forecasting that solar power tariff would drop to 1 5 1 9 US unit in near future 244 187 The lowest solar tariff in May 2018 is Rs 2 71 kWh without incentives which is less than the tariff of Bhadla solar park 2 44 per kWh with VGF incentive after the clarification that any additional taxes are pass through cost with hike in the tariff 245 246 In early July 2018 bids the lowest solar PV tariff has touched 2 44 3 1 US per kWh without viability gap funding incentive 247 248 In June 2019 the lowest tariff is 2 50 3 1 US kWh for feeding in to the high voltage interstate transmission system ISTS 249 250 251 In February 2019 the lowest solar power tariff is 1 24 1 6 US per kWh for 50 MW contracted capacity at Pavagada Solar Park 252 253 The tariff for rooftop installations is also falling with the recent offer of 3 64 4 6 US with 100 locally made components 254 In August 2022 the installation cost of rooftop solar has reduced below 45 000 Rs KW for capacity between 1 and 3 KW 255 In May 2020 the discovered first year tariff is 2 90 3 6 US per kWh with 3 60 4 5 US per kWh levelised tariff for round the clock hybrid renewable power supply 256 In November 2020 Solar PV power tariff has fallen to 2 00 2 5 US per kWh 257 258 In March 2021 the discovered levelised tariff was 2 20 2 8 US per kWh after the imposition of basic customs duty BCD on imported solar PV panels and cells 259 The discovered tariff for floating solar power was 3 70 4 6 US per kWh in November 2022 260 In April 2023 the discovered minimum levelised tariff was 3 99 5 0 US per kWh for the round the clock hybrid solar power supply with

between the Tropic of Cancer and the Tropic of Capricorn The alliance of over 120 countries was announced at the Paris COP21 climate summit 272 One hope of the ISA is that wider deployment will reduce production and development costs facilitating the increased deployment of solar technologies to poor and remote regions citation needed Solar panel manufacturing in India EditAs of November 2021 manufacturing capacity of solar cells and solar modules in India was 4 3 GW and 18 GW respectively 273 Nearly 80 per cent of solar panel s weight is flat glass 274 100 150 tons of flat glass is used to manufacture a MW of solar panels Low iron flat or float glass is manufactured from soda ash and iron free silica Soda ash manufacturing from common salt is an energy intensive process unless it is extracted from soda lakes or glasswort cultivation in alkali soil To increase installation of photovoltaic solar power plants the production of flat glass and its raw materials must expand commensurately to eliminate supply constraints or future imports 275 The Ministry of New and Renewable Energy MNRE India has issued a memorandum to ensure the quality of solar cells and solar modules 276 277 Compliance with the requisite specifications will grant manufacturers and their specific products an entry in the ALMM Approved List of Models and Manufacturers 278 279 280 Indian
