India’s solar sector entered 2026 with a record-breaking start, adding 15.3 GW of capacity in the first quarter the highest quarterly addition ever and a 143% jump from last year. The growth reflects India’s rapid shift from policy ambition to large-scale execution, with solar now accounting for 77% of all new power capacity added during the quarter.
Much of the surge, however, has been driven by developers rushing to complete projects before new ALMM regulations take effect in June 2026. Concerns around domestic solar cell availability and possible cost increases have also accelerated installations, making the current boom heavily policy driven.
Improved transmission infrastructure in Rajasthan and Gujarat helped unlock delayed projects, with the two states contributing nearly 80% of utility-scale solar additions. Solar energy now makes up 28% of India’s total installed power capacity and over half of its renewable energy capacity.
Despite the strong growth, challenges remain. Solar auctions and tender activity declined sharply during the quarter, raising concerns about the future project pipeline. India is also trying to balance rapid solar expansion with domestic manufacturing goals, but supply-chain localization and DCR requirements could increase project costs if local manufacturing fails to scale quickly.
Energy storage is another major concern. Solar capacity is growing much faster than battery deployment, creating potential risks around grid stability, intermittency and peak-hour power demand.
India’s solar story is no longer aspirational it is operational. But the next phase will determine whether the country can build a stable, manufacturing-backed and infrastructure-ready renewable energy ecosystem capable of sustaining long-term growth.
