Solex Energy Ltd Q4 FY2025 Concall Summary

Key Takeaways

• Revenue miss, but margin beat: FY25 revenue fell short of the INR800 crore target because the second production line started in March instead of January, yet EBITDA margin of 11.5% and PAT margin of 6.4% exceeded internal estimates.
• FY26 guidance implies a sharp ramp: Management guided FY26 revenue at INR2,200–2,400 crore, roughly triple the FY25 run-rate, driven by a full year of 1.5 GW capacity plus six months of new 2.5 GW capacity starting October 2025.
• Cell manufacturing is the next big bet: A 2 GW cell line is planned with land identified and a key technical hire made, requiring INR1,200 crore of the total INR1,500 crore CapEx, with INR500 crore equity raise expected to launch in 2–3 months.
• US market is a material, near-term opportunity: Management has set focus on the US, arguing Indian modules remain cheaper even after tariffs and that US factories cannot meet domestic demand, with good orders expected next year.
• What to watch next quarter: Whether the October 2025 commercial production date for the new 2.5 GW line holds, the identity and terms of the large anchor customer, and progress on the INR500 crore equity raise for the cell line.

Production Ramp & the Revenue Miss

• Two-month delay explains the shortfall: The second production line was expected to start in January 2025 but commissioned only in March due to technological changes and other challenges, costing two months of output. Had it started on time, the company would have achieved approximately INR800 crore turnover.
• Inventory build-up is tied to the delayed line: Raw material was procured for the second production line but could not be converted and billed to clients before the line was commissioned, inflating inventory.
• Debtor increase reflects a March surge: Debtors rose because of very high sales in March 2025 (INR135 crore turnover) and EPC contributions, with some recoveries already happening in April and May.
• Capacity utilization is order-book driven: Current utilization runs at 70–75% with both production lines operating 24 hours a day, constrained by the order book rather than technical capability.
• Technology upgrade caused the expansion delay: The new 2.5 GW line was pushed from June to October 2025 because management opted for the most modern equipment with upgradability to back-contact and HJT, reflecting rapid industry technology shifts. Equipment is ready and shipment begins from July.

Chetan Shah: "There is no change in the plan. It is basically a change in technology, the frequent change in technology, which is where like we are considering the most modern equipment. Some of the equipments are not ready to be shipped out of the manufacturer's country, particularly China. It requires a lot of testing without compromising having the latest technology."

Order Book & Customer Concentration

• Existing lines are fully booked: Current production lines are completely sold out, and firm orders exist for the new lines, though MSAs are signed without POs for all of them yet.
• A single anchor customer dominates the book: Per an analyst's math referencing CRISIL data, one client accounts for INR1,020–1,300 crore of the INR1,450 crore order book. Management did not name the client but confirmed other smaller orders exist and that the large order is for the new lines.
• Debtors split reveals EPC skew: On a standalone basis, EPC debtors stand at INR69.21 crores versus module debtors of INR42.03 crores, totalling INR111.24 crores.
• Current liabilities include healthy customer advances: The jump in current liabilities from INR9.27 crore to INR62.25 crore is driven by sundry creditors, inventory, debtors, and customer advances of approximately INR55 crores.

Cell Manufacturing & CapEx Plan

• Total CapEx of INR1,500 crore: The plan allocates INR1,200 crore for the cell line, INR200 crore for the module line, and INR100 crore for working capital, funded by INR1,000 crore debt and INR500 crore equity.
• Debt raise is underway: INR300 crore of debt is being raised for expansion, split into INR150 crore term loan and INR150 crore working capital (INR100 crore fund-based, INR50 crore non-fund-based).
• Equity raise timeline is firming up: Management is talking with bankers and working on a structured model (possibly a subsidiary), and will approach investors within 2–3 months to raise INR500 crore for cell line equity.
• Cell margin guidance is deferred: Management acknowledged cell margins are currently very high but will come down by the time production starts, and said exact numbers will be provided when approaching the market for the equity raise, within 1–2 months.
• Cell line timeline is 18 months from ground-breaking: From zero ground level, minimum 18 months is needed, pointing to a start around FY26–FY27 end. Within one to two months, significant development is expected on the cell manufacturing front.
• Module expansion is demand-driven: An additional 2 GW module line was added to the original plan (which only included the cell line) because of strong demand, and management said module capacity will keep adding based on the order book.

Margins & Profitability

• EBITDA margin outperformed internal estimates: FY25 EBITDA margin of 11.5% beat the guided range of 9–11%, and PAT margin of 6.4% beat the approximately 5% guidance.
• Scale and own-brand shift drove margin expansion: Gross margins improved because the company shifted from OEM production to predominantly Solex-branded modules, plus increased scale and EPC business contribution.
• PAT margin guided at 6–7%: Management expects PAT margin to settle between 6% and 7% with scale, and targets maintaining PAT levels between 5% and 7%.
• EBITDA margin expected to hold around current levels: Management feels it can maintain the current EBITDA margin range (around 11.5%), subject to market dynamics, and is looking forward to better margins in days to come.
• Large-scale orders improve efficiency: Consistent large orders improve production efficiency and reduce operating costs, supporting higher margins.

Vipul Shah: "So a lot of things depend upon the market dynamics. And if the dynamics change, it will change for the entire industry. But at present, we see we should maintain this range."

US Market & Competitive Positioning

• US is a focused opportunity: Management has set focus on the US market and expects good orders next year, arguing that US factories are insufficient to meet domestic demand and that Indian modules remain cheaper even after tariffs.
• No Chinese export competition currently: Management stated no export is happening from China to the US or to India at present.
• Industry commoditization is not an immediate threat: Management believes that for the coming few years, sufficient business exists for all manufacturers given the demand-supply gap, and Solex has an edge through technology leadership and manufacturing reliability.
• Testing infrastructure is a differentiator: Solex has full-fledged testing facilities and is adding more to international standards, and was the first company to launch a 625 watt peak panel using G12R technology.
• MES software provides transparency: The entire production line runs on a Manufacturing Execution System, giving IPP players transparency during audits, which management credits for establishing Solex as a reliable brand despite being a new entrant.

Chetan Shah: "So at present, for coming few years, I don't see a challenge in the pressure due to the multiple manufacturers. Everybody will have a sufficient business. And particularly for Solex, since we are quite ahead in terms of technology, and we have established ourselves as one of the most reliable manufacturer globally, because of our manufacturing standards, which we have established, we have an edge over other manufacturers."

EPC Business & Subsidiary Structure

• EPC is deliberately selective: Management goes very carefully on EPC because it is a different domain and most customers are EPC companies themselves, so the company must avoid competing with its own clients.
• EPC revenue target is INR200–300 crore annually: This represents roughly 10–12% of total revenue, with private sector EPC (C&I, ground-mounted rooftops) routed through the Solex Green Energy Private Limited subsidiary and government EPC staying in the holding company.
• EPC contributes to margin improvement: The EPC business, alongside the shift to own-brand modules and scale, contributed to the increase in overall EBITDA and PAT.
