Solarworld Q4 FY26: Scale-up Year, Storage Entry, and a Margin Reset

Solarworld Energy Solutions Limited closed Q4 FY26 with a sharp jump in scale. Consolidated total revenue for the quarter was INR 606.95 crore, up 239% year on year. EBITDA rose to INR 73.28 crore with a 12.1% margin, and profit after tax (PAT) reached INR 49.06 crore, translating into an 8.1% margin.

For FY26, consolidated total income came in at INR 1,416.07 crore, up 157% over FY25. EBITDA was INR 187.93 crore, while PAT was INR 120.47 crore. The year was a clear expansion year on the topline, but also a year where profitability normalized from a very high base. EBITDA margin declined to 13.3% in FY26 from 21.0% in FY25, and PAT margin fell to 8.5% from 14.0%.

What changed in FY26: EPC growth, manufacturing start-up, and storage orders

The presentation positions Solarworld as an EPC-led company operating through CAPEX and RESCO models. It has executed 60+ projects and reported 348 MW DC installed capacity till date, with ongoing EPC capacity of 1,809 MW DC. During Q4 FY26, it also highlighted multiple large order wins, including a BOS package from NTPC Renewable Energy Limited and several BESS EPC projects at NTPC thermal power stations.

Management commentary explained that investors should read the EPC business and the module business separately. The company’s solar module manufacturing line received ALMM approval in December 2025, leaving only a short operating window during FY26. Management indicated this led to a loss in the module segment in FY26, with expectation of recovery in the next year.

The other pressure point was input inflation. Management described Q4 as challenging across the sector, citing significant increases in key commodities such as copper, aluminium, and steel. This context matters because Solarworld’s revenue growth is coming primarily through project execution, where the timing of procurement and the ability to pass through costs can materially influence margins.

Financial summary

Storage strategy: BESS becomes a core growth pillar

A central theme in both the presentation and the call was the shift toward integrated energy solutions, with BESS increasingly required for grid stability. Solarworld stated a target of a 60:40 BESS-to-solar EPC revenue mix. The company’s ongoing BESS projects were presented at 582 MW and 1,184 MWh.

Management also described BESS execution as structurally less prone to delays compared to solar EPC, mainly because storage projects require limited land and are typically near substations. This is a practical advantage in a market where land handover and right-of-way can materially disrupt solar EPC timelines.

On manufacturing, Solarworld’s 3.4 GW automated BESS facility is ready with trials underway. Management stated an estimated capex of around INR 55 to 60 crore for the BESS line and indicated it is already spent and in trial phase. Management also stated that BESS typically offers a better margin profile than solar and guided to around 14% to 15% PBT margin for BESS.

Backward integration: modules commissioned, cells targeted by June 2027

FY26 was also a milestone year for manufacturing. The company commissioned a 1.552 GW TOPCon module facility at Roorkee, Uttarakhand, with fully automated lines and ALMM certifications. Management’s comments suggest the plant’s core role is captive supply for Solarworld’s EPC execution rather than third-party module sales.

Management provided two useful operating datapoints: the module line’s break-even is expected at around 30% to 35% utilization, and an existing 600 MW requirement for an NTPC order could translate into roughly 40% to 45% utilization. Management also spoke about the possibility of reaching 60% to 65% utilization as more orders come in.

The next step is the solar cell line. The company is developing a 1.2 GW solar cell facility at Pandhurna, with commercial operations targeted by June 2027. In the call, management said approvals are largely received and civil construction is expected to begin around June.

This cell line timing also ties into the evolving domestic content environment. Management discussed upcoming domestic cell requirements and indicated there could be short-term solar cell supply constraints for the industry, though they expect the situation to improve toward the end of FY27 and into FY28.

Balance sheet signals: growth supported by higher working capital

The FY26 consolidated balance sheet highlights how sharply the scale-up has expanded working capital.

Trade receivables rose to INR 347.71 crore as of March 2026, up from INR 144.25 crore in March 2025. Inventories increased to INR 106.13 crore from INR 2.04 crore. Current borrowings increased to INR 190.68 crore from INR 50.16 crore, and finance cost rose to INR 20.65 crore in FY26 from INR 6.23 crore in FY25.

Management also referenced a consolidated debt-to-equity ratio of 0.3x as of March 31, 2026. While leverage remains moderate by that metric, the higher receivables and inventory indicate that execution-led growth is consuming more capital. For an EPC business, this is a key area investors typically track, because the timing of collections and project milestones can influence cash flows even when reported profits are strong.

FY27 outlook: execution guided from the existing order book

Management described the current order book at about INR 2,800 crore and indicated an intention to execute 70% to 75% of it in FY27, implying about INR 2,000 crore revenue. They also stated that BESS revenue was zero in FY26 and could rise to about INR 800 to 1,000 crore in FY27, while solar EPC revenue could remain around the prior year’s level.

On margins, management guided that overall margins could land in the 8% to 11% range, depending on commodity prices and broader geopolitical conditions. The commentary also emphasized a typical seasonal pattern for the business: Q1 and Q2 are generally weaker, while Q3 and Q4 are stronger.

Takeaways

Solarworld’s FY26 story is mainly about scale and positioning. Revenue growth was strong, the order book expanded to INR 2,813 crore, and the company moved deeper into energy storage with multiple PSU-linked BESS orders. At the same time, margins reset lower versus FY25, and the balance sheet shows a clear rise in working capital intensity.

For FY27, the market will watch two things closely: whether the company can convert a large portion of its order book into revenue, and whether margins hold within management’s guided range despite commodity and currency volatility. The progress on manufacturing, especially the ramp-up of the module facility and execution against the June 2027 cell plant timeline, will also shape how investors assess Solarworld’s longer-term integration strategy.
