Solex Energy Ltd Q3 FY2026 Concall Summary

Key Takeaways

• A transition quarter, not a demand problem: Revenue was held back by a delayed monsoon pushing EPC projects and module dispatches into Q4, not by order book weakness. The company still guided to ₹1,700–1,800 crore for FY26.
• Margins compressed sharply on start-up costs: Gross margins fell from ~30–32% to 17% as the new 2.2 GW Tadkeshwar facility carried full fixed costs (interest, depreciation) while ramping to optimum production only in December.
• The order book is deep, but pricing is in flux: A ₹4,000+ crore order book includes recent wins from Zelestra (₹544 crore) and a reputed IPP (₹289 crore), yet rising cell prices may force renegotiation of some fixed-price contracts.
• Technology bets are now concrete: India’s first Rear Contact module was unveiled, a cell line land deal is imminent, and BESS manufacturing exploration has begun with a technology partner.
• What to watch next quarter: Whether the ₹120–130 crore of delayed EPC revenue actually lands, the pace of margin recovery as utilization hits a targeted 70%, and how much of the order book gets renegotiated on cell prices.

The Q3 Miss: Monsoon, Ramp-Up and Inventory

• Extended monsoon broke the timeline: Line 3 and 4 at Tadkeshwar (2.5 GW combined) were targeted to start in October, but monsoon ran into November. Full-fledged optimum production began only in December, so the quarter carried all fixed costs with little volume to absorb them.
• EPC revenue pushed out: The same monsoon delayed all EPC projects by 2–3 months, shifting roughly ₹120–130 crore of targeted revenue into Q4.
• Inventory piled up for a reason: Finished goods of ~₹150 crore and raw material of ~₹200 crore sat on the balance sheet at quarter-end, aligned with large orders in hand. An additional ₹150 crore of inventory rolled over from Q2 because customer sites were not ready, though one customer paid a 100% advance of over ₹400 crore for those delayed dispatches.
• Dispatch patterns are lumpy by design: Major IPP clients have minimum dispatch quantities (10–20 MW) and testing protocols, so production runs 24/7 but revenue recognition concentrates in the final quarter.

Vipul Shah: "Initially we targeted was, line 3 and 4 will be operational from the beginning of October. But as we have mentioned earlier, because of extended monsoon, the projected capacity started late. And then again, it takes time to ramp up. So practically full-fledged production for the line 3 and 4 at the optimum level has started from December."

Margin Walk: Fixed Costs Hit Before Volume Arrived

• Gross margin collapsed on operating leverage, not material cost: Gross margins fell from ~30–32% to 17%. Management attributes the drop to a larger share of lower-margin EPC business in the mix and fixed overheads from the new facility. Raw material margin impact was only 2–3%.
• Fixed-price orders are hedged: Current orders are fixed price and raw material has already been secured, insulating Solex from near-term commodity moves.
• Recovery thesis rests on volume: As capacity utilization improves and volumes ramp in Q4, operating leverage is expected to pull margins back toward normal levels. The company is targeting almost 70% utilization in Q4, running three shifts including Sundays.
• PAT margin question left ambiguous: When an analyst suggested full-year PAT margins of 6–8% on the ₹1,700 crore guidance, management answered “Yes” but did not independently state or confirm a specific range.

Order Book & Revenue Visibility

• The backlog is substantial: The order book stands above ₹4,000 crore, with recent headline wins from Zelestra Group (₹544 crore, execution February to November 2026) and a reputed IPP (₹289 crore for N-Type TOPCon modules).
• FY26 revenue guidance held: Management expects to close FY26 at ₹1,700–1,800 crore, implying a very large Q4 as delayed EPC and module dispatches convert.
• Cell price renegotiation is an open risk: Rising cell prices mean some fixed-price orders may need to be renegotiated, and some customers may defer plans by a couple of months waiting for prices to ease. Management declined to quantify what percentage of the order book is affected, saying only that most MSAs and orders have dynamic pricing provisions for cells.
• FY27 production already mapped: The company has a clear production and dispatch projection for FY27, though no numbers were disclosed.

Technology & Capacity Roadmap

Module and cell expansion

• Current capacity: 4 GW of module manufacturing, with a target of 10 GW by 2030.
• Cell line: A 2.2 GW N-type TOPCon Plus solar cell production line is planned, targeting operations by 2027. Land search faced a setback with GPCB and environment clearances on one site, but the company is on the verge of closing a new land deal in Gujarat.
• Ingot and wafer: Plans for 2 GW of ingot and wafer production in coming years.
• Funding: Term sheets from investors for ₹300–400 crore are expected within the next week, with 4–5 options being explored.

Rear Contact technology

• India-first launch: Solex unveiled India’s first TAPI Rear Contact (TRC) solar module in October 2025, with commercial production targeted by FY27. Certification is in preparation.
• ISC Konstanz partnership: Solex is the first Indian company to collaborate with the German R&D institute, a pioneer in back-contact technology, for developing back-contact solutions for both modules and cells. The next cell manufacturing expansion will be in back-contact.

Chetan Shah: "We have collaborated with them and they are helping us to develop back-contact solutions, module and cells both."

BESS

• Early-stage exploration: The company has initiated discussions with a technology partner for manufacturing BESS containerized solutions and large-site kits. A manufacturing scale and technology decision is expected “in no time.”
• Timeline: The BESS opportunity is expected to begin in the later part of FY27 (December 2026 or January 2027), pick up through late 2028, and peak around October 2028.

Chetan Shah: "I think the BESS is going to be the next game changer in renewable space and it will solve a lot of teething problems which we are facing right now in terms of the solar generation in daytime and then absorption of solar power in a daytime has become challenging and then there are no storage solutions which we can speak to the grid in a night-time and we can utilize the grid by 24/7."

Policy Tailwinds

• Union Budget FY27 allocated ₹30,540 crore for solar energy schemes, a 32% increase, with ₹22,000 crore for PM Surya Ghar (up 29%) and ₹5,000 crore for PM KUSUM. These schemes directly support the rooftop and distributed solar segments Solex serves.
