Solar PV installations in India have surged in 2025 with a record 34.98GW of new additions in the first 11 months of the year, according to the Indian Ministry of New and Renewable Energy. This figure is for deployments up until the end of November 2025, and is more than a 67% increase from the same period in 2024, when India witnessed 20.85GW of new solar PV installed.
According to JMK Research, nearly 3GW of solar PV were added in November 2025 alone. The leading states for new utility-scale solar PV additions that month were Maharashtra (with 802MW), Rajasthan (526MW) and Gujarat (509MW). Both Maharashtra (with 193.4MW) and Gujarat (130MW) were also the leading states for rooftop solar PV additions in November.
Solar PV represented the bulk of new renewable energy capacity in 2025, which reached a record 44.5GW. Moreover, a further 105GW is in the pipeline as of the end of November 2025, according to the MNRE, of which 35GW is capacity that has been tendered.
The accelerated growth was not exclusive to the downstream industry, with manufacturing capacity also increasing drastically. The annual nameplate capacity for modules reached 144GW at the end of November 2025, of which 81GW alone were added in 2025, nearly doubling the annual nameplate capacity added in 2024 for modules.
“The PLI Scheme for High-Efficiency Solar PV Modules is helping in developing and enhancing solar manufacturing across various stages. Beneficiaries under PLI Scheme installed around 11 GW of solar PV module manufacturing and around 5 GW of solar PV cell manufacturing capacities during 2025 under the scheme,” said the MNRE.
Despite the Production Linked Incentive (PLI) giving a significant boost to the domestic solar PV manufacturing landscape since 2022, some hurdles still remain to build a complete domestic supply chain. Both polysilicon and wafer production capacities lag behind those of modules and solar cells, with only 3.3GW of operational polysilicon production capacity and a 5.3GW annual nameplate capacity for wafers.
More recently, the Indian government plans to increase the efficiency of solar PV modules on the ALMM starting from 2027. For utility-scale solar projects, the threshold would be moved up from 20% to 21% for crystalline silicon (C-SI) and 19% to 20% for cadmium telluride (CdTe) based modules starting from 1 January 2027, before increasing by a further half percentage point for both C-Si and CdTe.
