India’s solar market is now big enough that the bottleneck is no longer demand. It is cells, grid access, approvals, and engineering capacity. An EPC planning the next 18 months needs the official numbers, not the press release adjectives.
This outlook uses only government data: MNRE’s physical progress report and its 8 April 2026 year-end statement. Every figure carries its date.
Quick answer. India had 168.04 GW of installed solar capacity on 31 August 2026, according to MNRE. The country added a record 44.61 GW of solar in FY 2025-26 and 17.78 GW more from April to August 2026. Growth in 2026 is shaped by the ALMM List-II solar cell requirement, in force since 1 June 2026, grid connectivity rules, and the push toward 500 GW of non-fossil capacity by 2030.
TL;DR
- Solar reached 168.04 GW on 31 August 2026, about 57% of India's 295.55 GW renewable capacity.
- Ground-mounted plants are 74% of solar capacity. Grid-connected rooftop is about 19%.
- Rajasthan and Gujarat together hold about 47% of installed solar.
- ALMM List-II for cells applies from 1 June 2026. Net-metering and open access projects have an exemption until 31 December 2026.
- Non-fossil capacity stood at 304.33 GW, about 61% of the 500 GW goal for 2030.

How big is the India solar market in 2026?
MNRE’s physical progress report gives cumulative capacity as on 31 August 2026.
| Segment | Installed capacity (GW) | Share of solar |
|---|---|---|
| Ground-mounted solar plants | 123.99 | 73.8% |
| Grid-connected rooftop solar | 32.59 | 19.4% |
| Off-grid solar | 6.63 | 3.9% |
| Hybrid projects (solar component) | 4.83 | 2.9% |
| Total solar | 168.04 | 100% |
Shares are our calculation from the MNRE figures. Total renewable capacity, including large hydro, was 295.55 GW on the same date. Wind was 58.52 GW.
How fast is India adding solar capacity?
FY 2025-26 was the record year. MNRE’s 8 April 2026 statement on PIB reports these figures.
| Metric | Value | Date or period |
|---|---|---|
| Solar capacity | 150.26 GW | 31 March 2026 |
| Solar added in FY 2025-26 | 44.61 GW | April 2025 to March 2026 |
| Non-fossil capacity added in FY 2025-26 | 55.29 GW | Highest in any year |
| Distributed solar added in FY 2025-26 | 16.3 GW | Includes 7.6 GW PM-KUSUM and 8.7 GW rooftop |
| Solar module manufacturing capacity | About 172 GW | 31 March 2026 |
| Solar added in FY 2026-27 so far | 17.78 GW | April to August 2026 (MNRE) |
| Solar added in August 2026 | 3.45 GW | MNRE |
Distributed solar was 36% of FY 2025-26 additions. That matters for EPCs: a third of the market is small, many-site work, where design throughput and DISCOM paperwork decide margins.
Where is India’s solar capacity being built?
MNRE’s state-wise capacity report as on 31 August 2026 shows a concentrated market.
| State | Total solar (MW) | Ground-mounted (MW) | Rooftop (MW) |
|---|---|---|---|
| Rajasthan | 44,370 | 38,897 | 2,316 |
| Gujarat | 34,880 | 24,947 | 8,147 |
| Maharashtra | 20,399 | 12,171 | 5,978 |
| Tamil Nadu | 14,354 | 12,642 | 1,636 |
| Karnataka | 12,014 | 10,485 | 938 |
Rajasthan and Gujarat together hold about 47% of installed solar. Among these five states, Gujarat and Maharashtra have the most rooftop capacity.
Each state has its own DISCOM, CEIG, and net-metering process, so a multi-state pipeline means multiple document sets. Our state solar policies guide tracks the differences.
What does ALMM List-II change for EPCs in 2026?
The Approved List of Models and Manufacturers (ALMM) now has two lists. List-I covers modules and List-II covers cells. From 1 June 2026, covered projects must use List-I modules made with List-II cells.
Net-metering and open access projects got a narrower window. MNRE’s Office Memorandum of 18 July 2026 lets them commission without List-II cells until 31 December 2026, according to PV Tech. List-I modules remain mandatory. Our India solar open access state guide covers the other rules those projects face.
Engineering consequences:
- Bill of materials. Module datasheets and BOQs must name compliant makes for the project’s commissioning date.
- Schedule. For C&I projects, the commissioning date, not the order date, decides which rule applies.
- Price and supply. Domestic cell supply is tighter than module supply, so module choice can change late. Keep layouts flexible on module dimensions.
Read the full timeline in our ALMM List-II commissioning deadline guide and the ALMM glossary entry.
Which other policy changes shape the market?
The same MNRE statement lists several changes that reach design and bid teams.
| Change | What MNRE says | Why it matters for engineering |
|---|---|---|
| Quality Control Order 2025 | Revised order notified 27 January 2025; covers modules, storage batteries, and inverters | Equipment must meet the listed Indian Standards; check certification in submittals |
| CERC connectivity amendment (2025) | Introduced a non-solar hour connectivity framework | Hybrid and storage projects can share transmission access |
| ISTS charges amendment (2025) | Waiver trajectory for RE and BESS projects | Commissioning dates affect transmission cost |
| BCD exemption | Capital goods for lithium-ion cell manufacturing for BESS, 2 February 2026 to 31 March 2028 | Supports domestic battery supply over time |
| Renewable Energy Potential Zones | About 345 GW declared beyond the 500 GW transmission plan | Gives early visibility for site selection |
Storage is the common thread. More tenders now ask for solar with batteries, so EPCs need BESS sizing skills in the bid team.
How close is India to the 500 GW goal?
India targets 500 GW of non-fossil capacity by 2030. On 31 August 2026, non-fossil capacity was 304.33 GW, including 8.78 GW nuclear, according to MNRE. That is about 61% of the goal.
Solar is doing most of the work. It is 168.04 GW of that total, and it supplied most of the FY 2025-26 additions.
What should EPCs plan for in the rest of 2026?
The numbers point to five practical moves.
- Lock the module and cell basis per project. Tie the BOQ to the commissioning date and the ALMM rule that applies.
- Prepare for rooftop and KUSUM volume. Distributed work needs fast, repeatable design and DISCOM documents. See our guides to PM Surya Ghar and PM-KUSUM.
- Track tenders early. Our SECI tender calendar lists open bids and the engineering each one needs.
- Plan for grid limits. Check connectivity and curtailment risk before committing to a site.
- Add storage capability. Hybrid tenders need integrated solar and battery design.
How Heaven Designs helps Indian EPCs
We prepare bid-stage and execution engineering for rooftop, C&I, and utility projects across Indian states. That includes CEIG electrical drawings, solar post-design packages, and MW-scale project management consultancy.
We do not promise approvals. Each DISCOM, CEIG office, and lender sets its own requirements, and we design to the documents you share.
