India Installed a Record 26 GW of Solar in H1 2026 — What It Means for Industry

India installed 26 GW of solar capacity in the first half of 2026 (January–June), a 43% jump year-on-year, lifting cumulative installed solar to about 162 GW by end-June. Rooftop solar was the standout, growing 104% YoY to ~6.4 GW — driven mainly by the PM Surya Ghar: Muft Bijli Yojana. For industrial and commercial buyers, the record signals a maturing market with more domestic supply, competitive auctions and a fast-growing rooftop segment — but also a tighter cell-supply environment in the second half as the ALMM List-II mandate bites.

Key Takeaways

• 26 GW of solar added in H1 2026 (Jan–June), up 43% YoY — nearly 70% of all the solar India added in calendar 2025.
• Cumulative installed solar reached ~162 GW by end-June 2026 (MNRE); solar is ~56% of India's ~288 GW renewable capacity.
• Rooftop grew 104% YoY to ~6.4 GW, led by PM Surya Ghar residential adoption and Tier-II/III city uptake.
• Utility-scale added ~19 GW (+32% YoY); Gujarat (7.6 GW) and Rajasthan (6.6 GW) led state additions.
• JMK Research expects ~47 GW of solar + wind in calendar 2026, on track for the 500 GW non-fossil target by 2030.
• For C&I buyers: more domestic module capacity, low utility-scale tariffs (₹2.34/kWh in Gujarat's March auction), but watch ALMM-II cell costs in H2. See our module pricing trends guide.

How much solar did India install in H1 2026?

According to JMK Research & Analytics and MNRE data, India added roughly 26 GW of solar between January and June 2026 — one of the strongest first-half performances on record and already ~70% of the ~38 GW installed in all of calendar 2025. June 2026 alone saw about 5.1 GW commissioned. By segment:

Cumulative installed solar reached 162.15 GW at end-June 2026 (MNRE), with ground-mounted at ~121 GW, rooftop above 30 GW, hybrid ~4.4 GW and off-grid ~6.4 GW. This is distinct from the earlier FY2026 milestone covered in our India solar record FY2026 analysis — that tracked the fiscal year (44 GW); this is the calendar H1 2026 figure.

Which states drove the record?

Gujarat and Rajasthan alone accounted for over half of H1 additions, reflecting their solar-park pipeline and high irradiance. For North India C&I buyers, Rajasthan's continued buildout is directly relevant to open access supply and landed cost — see our Rajasthan open access charges guide.

Why did rooftop solar grow 104%?

The rooftop surge is the headline story for distributed solar. Residential rooftop led, supported by the PM Surya Ghar: Muft Bijli Yojana, which had crossed 40 lakh beneficiary households and is projected to reach 75 lakh by December 2026. A notable shift: the fastest uptake is now in Tier-II and Tier-III cities (Lucknow, Nagpur, Surat, Varanasi, Ernakulam) rather than metros.

For C&I buyers, the residential boom matters less directly, but it signals three things: net-metering infrastructure is scaling, DISCOMs are processing applications faster, and the broader rooftop supply chain (installers, inverters, structures) is maturing. See our net metering policy guide and DHBVN net metering guide for the Haryana-specific process.

What do recent auctions tell C&I buyers?

Utility-scale auction tariffs stayed low in H1 2026, which anchors the economics for group captive and open-access procurement:

These tariffs show utility-scale solar remains the cheapest new electricity in India, though storage-backed and firm/dispatchable products command a premium (₹6.27–6.28/kWh). Compare procurement models in our CAPEX vs OPEX vs Open Access guide.

What does the rooftop-vs-utility split mean going forward?

H1 2026's split — ~19 GW utility-scale vs ~6.4 GW rooftop — shows two distinct growth engines. Utility-scale is driven by central and state auctions (SECI, NTPC, GUVNL, PSPCL) and feeds open access and group captive supply. Rooftop is driven by PM Surya Ghar (residential) plus C&I self-consumption economics.

For C&I buyers, the rooftop number matters because it reflects installer and inverter supply-chain capacity scaling — the same pool of EPC firms and equipment that serves industrial rooftop. As rooftop volume grows, installer lead times and component availability improve for everyone. But the residential subsidy wave is distinct from C&I economics: a factory's rooftop decision rests on tariff arbitrage and self-consumption ratio, not subsidy. See our how to size a solar plant guide and solar panel ROI/payback guide for the C&I math.

What could slow H2 2026?

The record H1 sets up a strong full-year, but the second half faces headwinds:

• ALMM List-II (Indian-cell mandate) from 1 June 2026 — government and government-backed projects must use modules made with ALMM-listed Indian cells. Industry expects a near-term cell crunch and cost pressure; see our ALMM List-II impact analysis.
• Module price inflation — domestic module prices rose ~33% since late December 2025 on commodity costs, China wafer-quota changes and the ALMM transition. See our module pricing trends guide.
• Geopolitical and logistics risk — Middle East tensions, rupee depreciation and Chinese oversupply could move prices either way.
• Domestic cell capacity lag — India has ~193 GW of module capacity but only ~31 GW of cell capacity (May 2026), so the cell mandate strains supply before new capacity ramps.

For C&I rooftop buyers, the practical takeaway: lock in module procurement early in H2, prefer ALMM-compliant Tier-1 suppliers, and don't assume 2025 pricing holds. See our how to read a solar EPC quote and how to choose a solar EPC company.

FAQ

How much solar did India install in H1 2026?

About 26 GW in January–June 2026, up 43% YoY, according to JMK Research and MNRE data. That's nearly 70% of the ~38 GW added in all of calendar 2025.

What was India's total installed solar capacity by June 2026?

Roughly 162 GW cumulative, per MNRE — including ~121 GW ground-mounted, 30+ GW rooftop, ~4.4 GW hybrid and ~6.4 GW off-grid.

Why did rooftop solar grow so fast in 2026?

Residential rooftop grew 104% YoY in H1 2026, driven by the PM Surya Ghar: Muft Bijli Yojana subsidy, faster approvals and rapid Tier-II/III city adoption. Note: PM Surya Ghar is residential; C&I rooftop economics depend on tariff arbitrage, not the subsidy.

What is the 2026 full-year solar forecast for India?

JMK Research expects ~47 GW of solar + wind added in calendar 2026, with solar alone earlier projected at ~42.5 GW — subject to ALMM-II and module-price headwinds in H2.

Does the H1 record affect industrial solar buyers?

Yes. Low utility-scale tariffs (₹2.34/kWh in Gujarat's March auction) anchor open-access and group-captive economics, but ALMM-II cell costs and module inflation could tighten C&I project economics in H2 — so early procurement and ALMM-compliant suppliers matter.

Is the 26 GW figure the same as the 44 GW FY2026 number?

No. 26 GW is calendar H1 2026 (Jan–June); the 44 GW figure is fiscal FY2026 (April 2025–March 2026). They overlap in period but are different metrics — see our FY2026 record analysis.
