India added 26.6 GW of solar capacity in the first nine months of 2025, up 53.7% from a year earlier, with large-scale projects providing most of the growth, according to Mercom India.
India deployed 2.8 GW of rooftop solar in January-June 2025, up 155% from 1.1 GW a year earlier, according to Mercom India.
India installed 18 GW of solar in the first half of 2025, a 31% increase from a year earlier, with 11.3 GW commissioned in the second quarter alone, according to Mercom India Research.
India installed 3.2 GW of rooftop solar in 2024, marking an 88% increase from 2023, driven by record residential installations. In the fourth quarter of 2024 alone, 1.3 GW were added, surpassing all previous quarterly installations.
Mercom Capital Group says inflation, high interest rates, trade disputes and policy ambiguity all contributed to a drop in corporate funding and merger and acquisition (M&A) activity in the solar sector last year.
Total corporate funding in the solar industry reached $22.3 billion in the first nine months of 2024, down 23% year on year. Mercom Capital Group says global uncertainties are affecting investor confidence, but an increase in debt financing and resilience in newly announced large-scale project funding are bright spots for the sector.
India added 14.9 GW of new solar capacity in the six months ending June, breaking all previous half-yearly and annual PV installation records.
Corporate funding in the solar sector reached $16.6 billion in the first half of this year, according to Mercom Capital Group. It says most funding came via debt financing, as venture capital and public market financing fell.
Mercom Capital Group says that total corporate solar funding, global venture capital funding, public market financing, and PV mergers and acquisitions all fell year on year in the first quarter of 2024. The sector is still grappling with high interest rates, which Wood Mackenzie says is disproportionately affecting renewables projects.
Despite inflationary challenges and elevated interest rates, financing in the solar industry has remained robust with corporate financing sitting at $28.9 billion – a 55% hike from last year’s $18.7 billion, a new report by Mercom Capital Group states.
