India is likely to miss its 2022 target of installing 100 gigawatts (GW) of solar power capacity, largely due to inadequate uptake of rooftop solar, according to a report by JMK Research and the Institute for Energy Economics and Financial Analysis (IEEFA).



  • As of December 2021, India’s cumulative installed solar capacity was 55 GW, with grid-connected utility-scale projects making up 77% of the total and the rest from grid-connected rooftop solar (20%) and mini or micro off-grid projects (3%).
  • With just eight months of 2022 remaining, only about 50% of the 100GW target, consisting of 60 GW of utility-scale and 40 GW of rooftop solar capacity, has been met.
  • Approximately 19 GW of solar capacity is expected to be added in 2022 — 15.8 GW from utility-scale and 3.5 GW from rooftop solar.


About the ‘Rooftop Solar Scheme’

  • It aims to achieve a cumulative capacity of 40,000 MW from Rooftop Solar Projects by the year 2022.
  • In a grid-connected rooftop or small Solar Photovoltaic (SPV) system, the DC power generated from the SPV panel is converted to AC power using the power conditioning unit and is fed to the grid.
  • The major objective of the programme includes -:
      • To promote the grid-connected SPV rooftop and small SPV power generating plants among the residential, community, institutional, industrial and commercial establishments.
      • To mitigate the dependence on fossil fuel based electricity generation and encourage environment-friendly Solar electricity generation.
      • To create an enabling environment for investment in the solar energy sector by the private sector, state government and the individuals.
      • To create an enabling environment for the supply of solar power from rooftop and small plants to the grid.
  • This scheme is being implemented in the state by power distribution companies (DISCOMs).
  • Under this scheme the Ministry is providing a 40% subsidy for the first 3 kW and 20% subsidy beyond 3 kW and upto 10 kW of solar panel capacity.
  • The residential consumer has to pay the cost of rooftop solar plant by reducing the subsidy amount given by the Ministry as per the prescribed rate to the vendor.


About the ‘National Solar Mission’

  • Launched in 2010, the Jawaharlal Nehru National Solar Mission, also known as National Solar Mission, is one of the eight key National Mission’s which comprise India’s National Action Plan on Climate Change (NAPCC).
  • The Mission has set the ambitious target of deploying 20,000 MW of grid connected solar power by 2022, which was revised to 1,00,000 MW by 2022 during June 2015.
  • To create an enabling policy framework for the deployment of 1,00,000 MW of solar power by 2022. The target will principally comprise of 40 GW Rooftop and 60 GW through Large and Medium Scale Grid Connected Solar Power Projects.
