- 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.
- Solar photovoltaic Potential (SPV) showed a general decline in stations of IMD.
- 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.
