Gujarat, not Rajasthan, is the sunniest state: ISRO study

It’s been long thought that Rajasthan is India’s sunniest state, but a mapping of solar energy hotspots by the Indian Space Research Organisation (ISRO) has found that Gujarat receives the highest levels of solar radiation, making it the best place in the country to set up solar power plants.

Identifying states and land masses that receive maximum solar energy assumes significance with the Jawaharlal Nehru National Solar Mission’s target to install 20,000 megawatt of grid-connected solar power plants by 2022 and parity with coal-based thermal power by 2030. At present, solar energy accounts for less than 1% of the total power generation capacity in India.

“The Indian land mass receives one of the highest levels of solar energy in the world, which still remains untapped and underutilised,” said Bimal K Bhattacharya, earth ocean atmosphere planetary science and applications area, Space Applications Centre, ISRO. “These assessments will therefore facilitate decisions on site-selection for installation of new large scale solar-based power generation systems and also to compute rooftop solar energy potential in urban and rural India.”
