India Q1 2026 Solar Record: What EPCs Need to Know

What the Q1 2026 Solar Installation Record Actually Shows

India installed 15.3 GW of new solar capacity in Q1 2026, per Mercom India Research's Q1 2026 India Solar Market Update, the highest quarterly addition on record. This represents a 143% year-over-year increase from 6.3 GW in Q1 2025, and a 49% jump from the 10.3 GW added in Q4 2025.

The breakdown:

• Large-scale solar: 12.6 GW, 82% of total additions, up 55% quarter-over-quarter and 147% year-over-year.
• Open access projects contributed 21% of large-scale capacity additions; separately, open-access solar specifically added 2.7 GW, up 59% QoQ and 170% YoY.
• Solar accounted for 77% of all new power generation capacity added in India during the quarter, not just renewable capacity.
• Cumulative installed solar capacity reached 152 GW as of March 2026. Solar now represents 28% of India's total installed power capacity and 55% of installed renewable capacity.

The Real Driver: ALMM List-II

Every documented source on this surge, Mercom India, PV Tech, PV Magazine, points to the same cause: developers accelerating project commissioning ahead of ALMM List-II taking mandatory effect on June 1, 2026. This requires solar cells, not just modules, to come from MNRE-approved domestic manufacturers, a deeper compliance layer than the longstanding module-level ALMM List-I requirement.

With domestic cell manufacturing capacity still a fraction of module manufacturing capacity, developers with projects already procured under the pre-List-II framework had a real incentive to commission before the deadline rather than risk sourcing constraints and rising module costs afterward. This is the documented cause of the Q1 rush, per every source that covered it.

Two additional factors reinforced the surge: improved transmission readiness in key solar markets, and developers accelerating open access projects ahead of the next phase of Inter-State Transmission System (ISTS) waiver reductions. Execution under the PM-KUSUM program also contributed to the quarter's strength.

What this means for EPCs going forward: the ALMM List-II transition isn't a one-time event that ended June 1. Exemption categories, extension mechanisms, and list revisions have continued shifting through mid-2026, most recently a blanket exemption extension for net-metering and open-access projects to December 31, 2026, announced July 18. Any EPC still planning around "the June 2026 deadline" as a fixed, closed event is working from an outdated picture.

Impact on EPC Project Pipelines

The ALMM-driven rush reshaped EPC pipelines in three observable ways:

1. Front-loaded commissioning pressure. Projects that could reach commercial operation before June 1 were prioritized aggressively, compressing engineering and construction timelines industry-wide.
2. Heavier concentration in large-scale work. Large-scale solar's 82% share of additions, and its 147% year-over-year growth, outpaced every other segment, meaning EPCs with utility-scale execution capability captured a disproportionate share of the surge.
3. ALMM compliance documentation became a live differentiator. EPCs able to move quickly on List-II cell sourcing verification, and advise clients accurately on exemption eligibility, had a real competitive edge during the rush.

Utility-Scale Solar Opportunities in 2026

Large-scale solar continues to lead India's growth, concentrated in Gujarat, Rajasthan, and Maharashtra, the three states driving the bulk of Q1 2026's large-scale additions. For EPCs, this segment offers:

• Design-build contracts consolidating civil, electrical, and commissioning scope to reduce interface risk, increasingly favored on larger projects.
• Open access project work, given its outsized 170% year-over-year growth specifically, a segment worth tracking separately from utility-scale generation projects.
• Domestic manufacturing partnerships. Cell capacity has stayed roughly flat through mid-2026, around 27-30 GW depending on measure, against module capacity in the 190-210 GW range, and Mercom itself convened an industry panel on July 1, 2026 specifically debating whether cell manufacturing is scaling fast enough. This gap is precisely what's driving current ALMM List-II sourcing pressure, and precisely where domestic supplier relationships carry the most value right now, particularly with new capacity like Navitas Solar's 3.6 GW Gujarat facility still in the pipeline rather than operational.

Practical Strategies for EPCs to Capture New Business

Build ALMM Compliance Into Every Proposal

• Verify current List-II cell sourcing status for every named supplier before finalizing a bid, given how frequently the list itself has been revised through 2026.
• Confirm current exemption status for net-metering and open-access projects directly, rather than relying on a fixed understanding of the June 2026 deadline.

Prioritize Domestic Supply Relationships

• Given the module-to-cell manufacturing capacity gap, qualify domestic cell suppliers specifically, not just module suppliers, as a distinct sourcing priority.
• Negotiate framework agreements that account for potential List-II sourcing shifts mid-contract.

Enhance Compliance Readiness

• Maintain a reusable compliance package covering ALMM List-I and List-II documentation, DCR certification, and exemption eligibility evidence.
• Track MNRE ALMM revisions directly rather than relying on a single point-in-time understanding of the rules.

Leverage Joint Ventures

• Partner with firms holding strong land-bank portfolios or state-level regulatory expertise in Gujarat, Rajasthan, or Maharashtra specifically, given their leading share of current activity.

Invest in Workforce Upskilling

• Train project managers specifically on ALMM compliance mechanics and current exemption categories, this has become a genuine differentiator, not just a general compliance topic.

Risk Management and Compliance for 2026 Projects

ALMM and Supply-Chain Risk

• Track domestic cell availability and pricing closely; the module-to-cell capacity gap is the direct cause of current sourcing pressure and is unlikely to close quickly.
• Build contracts with a defined mechanism for handling supplier delisting or List-II revision events mid-project, rather than assuming a supplier's compliance status is fixed at contract signing.

Financing Risks

• Financing tied to project commissioning timelines should account for potential ALMM-driven schedule compression on comparable projects; lenders have seen this pattern across the industry this year.

Regulatory Compliance

• MNRE and the Ministry of Power periodically update grid-code and RCO (Renewable Consumption Obligation) requirements; EPCs must track both alongside ALMM specifically, since these are separate compliance tracks.

Outlook for the Remainder of 2026

Given the ALMM List-II transition is ongoing rather than resolved, expect continued list revisions and exemption adjustments through the rest of 2026. EPCs should also watch:

• Further ALMM List-II revisions. The list has already been revised multiple times in 2026; treat any specific supplier's compliance status as time-sensitive, not fixed.
• Domestic cell manufacturing capacity additions. As new capacity comes online, the sourcing pressure driving current dynamics may ease, worth tracking as a leading indicator for future procurement planning.
• Continued open access growth. Given its 170% year-over-year growth rate, this segment is worth dedicated business development attention distinct from utility-scale project work.

What EPCs Must Do Now

• Verify current ALMM List-II status for every named supplier and project category before finalizing bids, given the pace of revisions.
• Confirm exemption eligibility directly for net-metering and open-access projects rather than relying on the original June 2026 deadline as fixed.
• Build compliance documentation packages covering both ALMM List-I and List-II requirements.
• Prioritize domestic cell supplier relationships specifically, distinct from module supplier relationships.
• Track state-level opportunity concentration in Gujarat, Rajasthan, and Maharashtra for large-scale work, and open access specifically for its outsized growth rate.

Frequently Asked Questions

Q1. What actually drove India's record Q1 2026 solar installations?

Developers rushing to commission projects before ALMM List-II became mandatory on June 1, 2026, which requires solar cells, not just modules, from MNRE-approved domestic manufacturers. Improved transmission readiness and accelerated open-access commissioning ahead of ISTS waiver reductions also contributed.

Q2. How much did India's solar installations grow year-over-year in Q1 2026?

143%, from 6.3 GW in Q1 2025 to 15.3 GW in Q1 2026, according to Mercom India Research. The growth wasn't evenly spread: large-scale solar grew 147% year-over-year to 12.6 GW, while open-access solar specifically grew even faster, 170% year-over-year to 2.7 GW. For an EPC evaluating where to focus, open access is currently outpacing the broader market's own record-setting growth rate.

Q3. Which states led India's large-scale solar additions in Q1 2026?

Gujarat, Rajasthan, and Maharashtra led large-scale solar capacity additions during the quarter, consistent with these states' established position in India's utility-scale solar buildout: high solar irradiation, larger tracts of available land, and more mature transmission infrastructure than most other states. An EPC without an existing presence in these three markets is competing for a smaller share of a market that's growing fastest exactly where it's already concentrated.

Q4. Is the ALMM List-II deadline still relevant now that June 2026 has passed?

Yes. The list itself has continued to be revised through mid-2026, and exemption categories, including a blanket extension for net-metering and open-access projects to December 31, 2026, have changed since the original deadline. EPCs should verify current status rather than treat June 1, 2026 as a closed, settled event.

Q5. Does this Q1 2026 pace mean the rest of the year will be slower?

Not necessarily predictable from Q1 data alone. The surge was driven by developers front-loading commissioning ahead of a specific compliance deadline, which is a different dynamic than steady underlying demand growth. Whether Q2 and beyond sustain this pace depends heavily on how ALMM List-II sourcing constraints and exemption timelines evolve, both of which have continued shifting through mid-2026. Treat Q1's number as a data point about deadline-driven behavior, not a confirmed new baseline run rate.

Q6. Does the Q1 2026 surge mean anything different for mid-size EPCs versus large utility-scale players?

Yes, worth separating the two. Large-scale solar's 82% share of total additions reflects utility-scale developers with the balance sheet to front-load commissioning ahead of a compliance deadline. Open access solar's faster 170% year-over-year growth rate is a more accessible entry point for mid-size EPCs without utility-scale project financing capacity, and it's currently the faster-growing segment of the two, worth weighing against the instinct to chase the larger utility-scale headline number.

Q7. How should an EPC verify a supplier's current ALMM List-II status before bidding?

Check the specific cell model against the current MNRE ALMM List-II revision directly, not just the manufacturer's overall brand reputation, since a manufacturer can be listed for some models and not others, and the list itself has been revised multiple times through 2026. Given how frequently this changes, treat any status check as time-limited rather than a one-time verification at contract signing.
