According to data from JMK Research, India added 37.9 GW of solar photovoltaic capacity in 2025, a 54.7% increase compared to 2024, setting a new historical record.
JMK’s data shows that 28.6 GW of new utility-scale solar capacity was commissioned in 2025, driven by “long-pending tenders awarded by various central and state agencies.” The growth in utility-scale solar installations reached 54.6% year-on-year.

JMK added that the expansion of domestic solar PV manufacturing capacity contributed to the higher deployment in 2025. The Indian government’s Approved List of Models and Manufacturers (ALMM) policy mandates that certain solar projects can only use approved domestically manufactured products.
Aside from utility-scale solar deployment, India added around 7.9 GW of rooftop solar capacity in 2025, a 72% increase from 2024. Approximately 60% of this capacity was added in the second half of the year, which JMK attributed to government subsidy incentives for household rooftop solar installations.
Only the off-grid and distributed solar segment saw a slight decline in 2025, with about 1.35 GW of new PV capacity commissioned, representing an 8.8% decrease compared to 2024.
India’s annual renewable energy installations and total installed capacity by the end of 2025.
In 2025, wind power installations grew by 6.3 GW, an 85.3% increase from 2024.
By the end of the year, according to India’s Ministry of New and Renewable Energy (MNRE), the country’s total renewable energy capacity reached approximately 258 GW. Solar PV accounted for 53% of this total, followed by wind (21%), large hydro (20%), bio-power (4%), and small hydro (2%).
State-wise solar installations followed expected trends. Gujarat and Rajasthan led with 11.1 GW and 10.2 GW of installed capacity in 2025, respectively, followed by Maharashtra (9.7 GW), Karnataka, and Tamil Nadu.
JMK’s figures are higher than the data released by MNRE earlier this month, which indicated that India installed slightly less than 35 GW in the first 11 months of 2025. JMK did not provide a month-by-month breakdown for the year, so the difference of approximately 3 GW may reflect installations in December, which were not included in MNRE’s data.
