    • Global solar radiation (GR) is the total amount of solar radiation that is being received per unit area on the earth surface.

     

    • Key findings 
      •  Solar photovoltaic Potential (SPV) showed a general decline in stations of IMD.
        • SPV is the amount of radiation that may be practically available to be converted to electricity by panels measured as kilowatt hours per installed kilowatt of capacity (KWh/kWp).
      • Gujarat and Rajasthan,where India’s largest solar parks are located are also showing a decrease in SPV potential.
      • Cause: increase in aerosol load due to fine particles from carbon emissions, fossil fuel burning and dust.
        • Aerosols absorb sunlight and deflect it away from the earth, and they can also form dense clouds that block sunlight.

     

    • Status of solar energy in India
      • Installed solar energy capacity stands at 81.81 GW as of Mar 2024.
      • India’s solar energy potential is estimated to be 748 Giga Watt peak as estimated by National Institute of Solar Energy.
      • India ranks 5th in Solar Power Capacity globally.
      • 50 solar parks with an aggregate capacity of 37.49 GW have been approved.

    Initiatives to promote solar power

    • The Production Linked Incentive Scheme (PLI) for the National Programme on High-Efficiency Solar Photovoltaic Modules.
    • Solar Park Scheme to establish 50 Solar Parks of 500 MW and above.
    • PM Surya Ghar Muft Bijli Yojana to provide subsidies to install solar panels on roofs.
