India Adds Record 27 GW Solar Capacity in H1 2026
India is building a lot of solar power, which turns sunlight into electricity.
In the first half of 2026, India added 27 gigawatts of solar power — that is a record and almost half more than the same time last year.
A gigawatt is a huge amount of electricity, enough to power many cities.
Most of the new power India added, about 76 out of every 100 units, came from solar panels.
Companies rushed to finish projects before new rules made solar parts harder to use and before a tax break got smaller.
Some states, like Gujarat, Rajasthan, and Maharashtra, built the most solar power.
In total, India now has 165 gigawatts of solar power installed.
That is about 30% of all the electricity India can make.
But the number of new projects being planned went down a lot this year.
India will need good planning and quick approvals to keep building solar power in the future.
India added a record 27 GW of solar capacity in the first half of 2026, up 49% from 18 GW a year earlier.
Solar accounted for 76% of the 36 GW of new power capacity added between January and June 2026.
Q2 2026 solar installations reached 12 GW, the second-highest quarter on record, though down 24% sequentially.
Cumulative installed solar capacity hit 165 GW as of June 2026, with Rajasthan, Gujarat and Karnataka leading utility-scale markets.
Large-scale solar tenders fell 54% to 11 GW and auctions declined 59% in H1 2026, signaling a slowdown in the project pipeline.
- Who
- Indian power developers and states such as Gujarat, Rajasthan and Maharashtra, with data reported by Mercom India Research.
- What
- India added a record 27 GW of solar capacity in the first half of 2026, with solar making up 76% of all new power capacity.
- Where
- India, led by Gujarat (40% of Q2 utility-scale additions), followed by Rajasthan (19%) and Maharashtra (17%).
- When
- First half of calendar year 2026, covering January through June.
- Why
- Developers accelerated commissioning ahead of the June 1 ALMM List-II implementation for solar cells and a cut in the inter-state transmission system charge waiver scheduled for July 2026, amid rising clean energy demand.
