India added 10 gigawatts (GW) of solar capacity in the calendar year (CY) 2021, a 210% increase year-over-year (YoY), compared to 3.2 GW installed in CY 2020, according to the newly released Q4 & Annual 2021 India Solar Market Update.

During CY 2021, large-scale solar projects accounted for 83% of installations with 8.3 GW and saw a 230% increase YoY. Rooftop installations made up the remaining 17% adding 1.7 GW, a 138% spike YoY.

A significant number of projects were moved from 2020 to 2021 due to COVID-19 extensions, which boosted the installation totals in 2021.
