India Solar Capacity 2026: A Record 27 GW Added in Just Six Months

India installed more solar capacity in the first six months of 2026 than in almost any comparable period in its history. Roughly 27 GW went up between January and June — a 49% jump from the 18 GW added in the same period of 2025 — and the pace shows no sign of slowing. Here's what's behind the surge, and what it actually means if you're considering solar for your own home or business right now.

How Much Solar Did India Add in H1 2026?

Figures as reported by Mercom India and other industry trackers based on government and developer data, as of mid-2026. Utility-scale and rooftop segments are combined unless stated otherwise.

Why the Sudden Surge — the ALMM-II Deadline

A large share of the H1 rush traces back to a June 2026 deadline tied to ALMM-II, the updated Approved List of Models and Manufacturers rules that tighten domestic-content requirements for solar modules used in government-linked and subsidy-eligible projects. Developers pushed hard to commission projects before the tighter rules kicked in, which pulled installation activity forward into the first half of the year.

The same rules are reshaping where components come from. India's ALMM-II regime has reduced direct solar cell imports from China, with sourcing shifting toward Southeast Asia — Indonesian cell imports reportedly nearly tripled in early 2026 as manufacturers adjusted their supply chains.

India Set to Overtake the US as the World's #2 Solar Market

At this pace, industry analysts expect India to overtake the United States as the world's second-largest solar market in 2026, trailing only China. That's a meaningful shift for a country that was adding a fraction of this capacity just five years ago, and it reflects both falling equipment costs and the scale of government programs like PM Surya Ghar pushing rooftop adoption alongside utility-scale growth.

What This Means If You're Planning a Solar Installation in 2026

• More installer competition in most cities — a larger market generally means more empanelled vendors bidding for your project, which is worth using to your advantage when comparing quotes.
• ALMM-listed panels matter for subsidy eligibility — if you're applying for the PM Surya Ghar subsidy, your installer must use ALMM-listed modules. Confirm this before signing any contract.
• Component sourcing is shifting — with cell imports moving away from China, ask your installer which manufacturer and origin your panels come from, and get the datasheet in writing.
• Don't assume last year's pricing still applies — with this much market movement, get fresh quotes rather than relying on numbers you saw even six months ago.
