Solarworld Q4 FY26: Scale-up in EPC and a clear push into BESS

Solarworld Energy Solutions Limited closed Q4 FY26 with a sharp jump in scale. Consolidated total income rose to 6,069.5 Mn, up 239 percent year on year. Profitability also improved in absolute terms, with EBITDA of 732.8 Mn, up 347 percent, and PAT of 490.6 Mn, up 420 percent. For the full year, total income grew 157 percent to 14,160.7 Mn, while EBITDA increased 63 percent to 1,879.3 Mn and PAT grew 56 percent to 1,204.7 Mn.

The quarter stood out because it showed Solarworld executing on two tracks at once. First, it scaled its core solar EPC engine, supported by a rising order book and strong PSU relationships. Second, it widened its footprint into Battery Energy Storage Systems, supported by multiple EPC wins from NTPC. The company now frames its growth as a broader energy infrastructure story, not only a solar EPC story.

That said, the annual margin profile tells an important counterpoint. EBITDA margin for FY26 was 13.3 percent versus 21.0 percent in FY25, and PAT margin was 8.5 percent versus 14.0 percent. The company still grew profits, but the mix and cost structure shifted as volumes expanded. Investors should read FY26 as a year of rapid ramp-up, with execution intensity and working capital needs rising alongside revenue.

What powered the Q4 surge

Solarworld’s Q4 revenue jump reflects a step-change in project execution and billing. Revenue from operations reached 5,918.1 Mn in Q4 FY26 compared with 1,764.1 Mn in Q4 FY25. The quarter also held up on profitability, with EBITDA margin rising to 12.1 percent from 9.2 percent a year ago. PAT margin improved to 8.1 percent from about 5 percent.

Cost lines moved in line with the higher run-rate. Cost of material consumed was 5,103.1 Mn in Q4 FY26, and total raw material cost was 5,169.1 Mn. Gross profit rose to 900.5 Mn, but gross margin compressed to 14.8 percent from 22.6 percent in Q4 FY25. The company still expanded EBITDA because overhead control improved and other expenses were lower year on year for the quarter.

Financing costs rose as scale and project needs increased. Q4 finance cost was 71.7 Mn versus 20.2 Mn in Q4 FY25. Depreciation also rose to 18.5 Mn, consistent with the asset base expanding after commissioning manufacturing capacity.

Core financial snapshot

Order book strength and a bigger pipeline

Solarworld’s visibility is tied closely to its order book. As of March 31, 2026, the order book climbed to 28,130.42 Mn from 17,005.51 Mn in FY25, reflecting a strong inflow cycle. The company also disclosed a snapshot of its scale indicators. It cited 16,742 Mn of solar EPC and O and M for ongoing projects, and 11,389 Mn including EPC for BESS IPP projects.

The ongoing projects list shows the shape of the business. Solar EPC orders are concentrated in large ground-mounted projects across Rajasthan, Gujarat, Assam, and Madhya Pradesh, often with O and M included. Storage appears as a distinct growth leg, with BESS orders from Rajasthan Rajya Vidyut Utpadan Nigam Limited, Gujarat Urja Vikas Nigam Limited, and NTPC.

In Q4 FY26, major order wins included multiple BESS EPC packages at NTPC thermal power stations. These included 132 MW and 264 MWh at Solapur for 3,142.69 Mn including O and M, 75 MW and 150 MWh at Solapur for 1,769.17 Mn including O and M, and 50 MW and 100 MWh at Unchahar for 1,082.27 Mn including O and M. On the solar EPC side, the company won a BOS package for a 200 MW AC and 260 MW DC grid connected solar PV project from NTPC Renewable Energy Limited for 2,347.17 Mn including O and M.

This mix matters because it signals where management wants the next phase to come from. The growth strategy in the presentation explicitly targets a 60:40 BESS to Solar EPC revenue mix over time. If that shift plays out, Solarworld’s revenue profile could change meaningfully, because storage EPC has different procurement cycles, execution risk, and margin and working capital characteristics compared with solar.

Manufacturing build-out and integration

Solarworld is building a more integrated platform. Its module manufacturing capacity is 1.552 GW, based in Roorkee, Uttarakhand, spread across 7.5 acres. The facility uses fully automated ATW and Horad lines commissioned in July 2025 and produces high efficiency TOPCon panels in the 610 to 750 W range across M10R, G12R, and G12 configurations. The company also states the plant has BIS, IEC, and ALMM certifications and is compliant with ISO 9001:2015 and ISO 14001:2015/2018.

Beyond modules, Solarworld described three additional manufacturing initiatives. A 3.4 GW fully automated BESS facility with KUKA robotics is ready, with trials underway. A 5 GW junction box line is being established through a joint venture, with the site ready for installation and trials underway. And a 1.2 GW solar cell facility is under development, with commercial operations targeted by June 2027.

This backward integration and component capability is framed as a margin and supply chain strategy. The company’s stated direction is to enhance captive module and cell consumption to improve margins and reduce dependency. For investors, the key question is timing and utilization. Module lines commissioned in July 2025 can support internal EPC needs, but the full benefit tends to depend on steady utilization and a stable procurement plan across projects.

Balance sheet scale and working capital signals

FY26 balance sheet numbers underline how quickly the business scaled. Total assets rose to 16,880.03 Mn at March 2026 from 5,980.15 Mn at March 2025. Current assets moved sharply higher to 14,568.28 Mn from 4,349.93 Mn.

The composition shows a working capital heavy model. Trade receivables increased to 3,477.06 Mn from 1,442.52 Mn. Inventories rose to 1,061.27 Mn from 20.43 Mn. Bank balances other than cash and cash equivalents jumped to 5,490.60 Mn from 1,160.33 Mn, and other current financial assets rose to 3,084.04 Mn from 869.45 Mn.

On the funding side, equity attributable to equity holders increased to 8,477.97 Mn from 3,090.66 Mn, reflecting the post-IPO capital base. Current borrowings increased to 1,906.79 Mn from 501.61 Mn, and trade payables also rose meaningfully. This is typical in an EPC company scaling execution, but it keeps attention on collections, milestone billing, and cost control.

Market context and why BESS is central

Solarworld anchors its growth narrative in the broader power demand cycle. The presentation points to power demand expected to grow 5.5 to 6.0 percent over the next five years, supported by infrastructure linked capex and expansion of transmission and distribution. It also highlights India’s accelerating solar capacity build-out, with cumulative solar capacity rising to 150.26 GW by March 2026 and a national target of 280 GW solar by 2030 as part of the 500 GW non-fossil capacity goal.

The company also positions storage as a key bridge between renewable generation and grid stability. It cites a government plan to develop 30 GW of BESS through a VGF scheme under the Power System Development Fund, with VGF provision up to 18 lakh per MWh and a total budgetary allocation of 5,400 crore. Against that backdrop, Solarworld’s early move into BESS EPC and its readiness of a 3.4 GW BESS manufacturing line are framed as strategic timing.

In the market opportunity section, the company cites BESS market growth in India with a 33.2 percent CAGR for 2026 to 2031. It also cites growth in EPC, O and M, and solar PV module markets. These are third-party estimates, but they explain why Solarworld is aligning capacity, order intake, and partnerships around both solar EPC and storage.

The year’s theme: execution first, then integration

Solarworld’s FY26 results show a company moving from a smaller base to a larger scale quickly. The numbers validate demand and execution capability, especially in Q4. Order book growth to 28,130.42 Mn provides near-term visibility, while BESS wins from NTPC signal credibility in a newer segment.

At the same time, the margin compression across FY26 is a reminder of what rapid scaling can do. Gross margin fell to 16.6 percent in FY26 from 28.2 percent in FY25, and EBITDA margin dropped to 13.3 percent from 21.0 percent. Finance costs increased to 206.53 Mn in FY26 from 62.32 Mn in FY25. These shifts do not cancel the growth story, but they make the next phase about disciplined execution, delivery quality, and balance sheet management.

The company’s strategy points to the levers management intends to use next. BESS expansion aims to change the revenue mix. Backward integration through modules and future cells aims to protect supply and improve economics. And a broader push across EPC, O and M, and storage aims to reduce reliance on any one sub-segment.

For investors, the key takeaways from Q4 FY26 are simple. Solarworld has demonstrated it can scale revenues quickly, it has secured meaningful PSU-linked order wins in both solar and storage, and it is investing in manufacturing capacity to support its platform. The next set of signals to watch will be whether margins stabilize as execution normalizes, and whether working capital intensity stays controlled as the order book converts into revenue.
