20 Top Solar Companies in India | Built In

India’s solar energy sector is heating up in an effort to meet the company’s ambitious goal of deriving 50 percent of its energy from renewable sources by 2030.

Fueled by $3.2 billion in government incentives, the country is now on track to be the world’s second-largest solar manufacturer by 2026. And while there is still an uphill climb to reach its goal of 280 gigawatts of solar capacity by 2030, India’s solar sector seems equipped for the challenge, as many factories have started measuring their solar capacity in gigawatts instead of megawatts.
