India added 13 gigawatts (GW) of solar capacity in the calendar year (CY) 2022, a 27% increase year-over-year (YoY), compared to 10.2 GW installed in CY 2021. Data was revealed in the newly released 2022 Q4 and Annual India Solar Market Update.

During CY 2022, large-scale solar projects accounted for 87% of installations and saw a 33% surge YoY. Rooftop installations decreased by 3.7% YoY. In Q4 2022, India added 2.6 GW of solar, a marginal decrease (2.5%) from 2.7 GW installed in Q3 2022. Installations were down 5% YoY compared to 2.8 GW in Q4 2021.

India’s cumulative installed solar capacity now stands at 63 GW.


According to the report, the growth outlook going into 2023 remains uncertain, with the pending judgment on projects stranded in the Great Indian Bustard region, the pending announcement on Approved lists of Models and Manufacturers (ALMM), and expected project extensions per MNRE’s direction to Solar Energy Corporation of India, Indian Renewable Energy Development Agency, NHPC, and NTPC.

The report highlights a rise in the average cost of projects throughout CY 2022 due to higher module prices and supply constraints. Average large-scale system costs in Q4 2022 increased by 7.3% YoY making it an unprecedented ten quarters of project cost increases in a row.

Rajasthan, Karnataka, and Gujarat were the top three states for cumulative large-scale solar capacity accounting for 54% of installations in the country as of December 2022.
