India’s solar transformation is one of the most rapid energy transitions witnessed in the world. From merely 3 GW in 2014, installed solar capacity has grown to about 129 GW by 2025, marking more than a forty-fold increase. Solar energy has now become the largest contributor to India’s renewable power sector, overtaking wind and hydropower in total installations.

India has also crossed a historic milestone by sourcing over half of its electricity capacity from non-fossil fuel sources. Out of nearly 500 GW total installed capacity, more than 259 GW now comes from solar, wind, hydro, nuclear and biomass, indicating a major structural shift away from fossil fuel dominance in electricity generation.
