Websol Energy System filed its Business Responsibility and Sustainability Report (BRSR) for FY26 on August 29, 2026. The filing details the company’s operational footprint, environmental metrics, and governance frameworks for the period ending March 31, 2026.

The Kolkata-based solar cell and module manufacturer reported a turnover of ₹1,049.44 crore and a net worth of ₹630.71 crore. The report highlights that 99.96% of the company's turnover stems from the manufacturing of photovoltaic solar cells and modules.

Operational and Workforce Metrics

The company operates from one plant and one office in India, serving customers across 15 states domestically and one international market. Exports contributed a marginal 0.12% to total turnover. The workforce comprises 140 employees and 855 workers as of the end of FY26.

Turnover rates for permanent employees stood at 23%, while permanent workers recorded a 24% turnover rate. The company noted that employee turnover data has been disclosed for the first time in FY26 following strengthened reporting processes.

Environmental Impact

Energy consumption remains a critical focus for Websol Energy. Total energy consumed from non-renewable sources was 1,76,507.28 GJ, while renewable sources contributed 0 GJ in FY26, compared to 35,901 GJ in FY25. The discrepancy in year-on-year figures is attributed to changes in measurement methodology and standardization approaches adopted in the current year.

Water withdrawal increased significantly to 3,37,221.12 kilolitres, primarily sourced from groundwater, up from 1,62,438.20 kilolitres in FY25. Total water consumption was 1,55,902.64 kilolitres. The company discharged 1,81,318.48 kilolitres of treated water to third parties.

Greenhouse gas emissions data shows total Scope 1 emissions at 224.60 tCO2e and Scope 2 emissions at 34,508.15 tCO2e. The company has not yet estimated Scope 3 emissions. Waste generation totaled 9,327.97 metric tonnes, with battery waste accounting for the largest share at 8,568 metric tonnes.

Governance and Social Initiatives

The board includes two female directors, representing 33% of the total board strength. Key Managerial Personnel (KMP) positions remain entirely male-led. The company reported four shareholder complaints during FY26, all of which were resolved by year-end. No complaints were received regarding communities, investors, or employees.

CSR provisions were not applicable for FY26 as the company did not meet the statutory criteria under Section 135 of the Companies Act, 2013. However, the company undertook community engagement activities benefiting over 1,265 individuals through health screenings, education support, and medical aid initiatives.

What the Numbers Show

A notable divergence exists in the company's environmental reporting metrics between FY25 and FY26. While non-renewable energy consumption appears to have decreased drastically in absolute terms (from 2,70,45,092 GJ to 1,76,507.28 GJ), the report explicitly states that the FY25 figure is not directly comparable due to differences in measurement methodology. Similarly, waste generation surged from 95.16 MT to 9,327.97 MT, driven by a comprehensive assessment of all plant waste sources in FY26 rather than an actual operational spike. These methodological shifts suggest improved data granularity rather than a sudden change in physical resource intensity.

Websol Energy System Limited reported robust top-line growth for the quarter ended June 30, 2026 (Q1FY27), with revenue from operations rising 70% year-on-year to ₹373 crore from ₹219 crore in Q1FY26. This performance was underpinned by significant improvements in operational utilization across its manufacturing facilities. Cell production more than doubled to 259 megawatt (MW) from 126 MW, achieving a utilization rate of 92%. Module production also surged to 103 MW from 50 MW, with utilization climbing to 81% from 39% in the corresponding quarter last year.

Despite the volume growth, profitability metrics showed mixed signals. EBITDA increased 21% to ₹126 crore from ₹103 crore, but the EBITDA margin contracted sharply to 34% from 47% in Q1FY26. Management attributed this margin compression primarily to a change in sales mix, with modules accounting for a materially larger share of revenue. Since module margins are lower than cell margins, the blended percentage margin declined even as absolute earnings grew. Profit after tax (PAT) rose 16% to ₹78 crore from ₹67 crore, translating to a PAT margin of 21%.

Balance Sheet Strengthening

In a significant move to de-lever the balance sheet, Websol Energy repaid its entire outstanding term loan of ₹110 crore with IREDA on August 4, 2026, using internal accruals. This repayment was completed without raising fresh capital or slowing ongoing growth investments. Consequently, the collateral attached to the loan, including promoter shares, is being released. Promoter pledge is expected to drop from 80% to 16% of the promoter holding. The company’s CRISIL rating remains BBB+ with a stable outlook.

Operational Metrics and Order Book

The company closed Q1FY27 with a confirmed order book of ₹1,278 crore, up from ₹1,161 crore at the end of March 2026. This provides visibility into near-term operations. Realizations for solar cells hovered around $0.125 per watt peak, while solar modules were realized at approximately ₹20.50 per watt peak during the quarter. Prices have seen a slight increase post-Q1 due to the anticipated implementation of the ALMM mandate, although the deadline was deferred to December.

Strategic Expansion and Technology Upgrade

Websol Energy is upgrading one of its existing mono PERC cell lines to TOPCon technology. The upgrade will add 150 MW of capacity, bringing total cell manufacturing capacity to 1.35 gigawatt (GW), with approximately 55% on TOPCon. The project entails an estimated capital expenditure of ₹270 crore, which the company plans to fund through internal accruals or debt financing. Completion is expected by March 2027, with a payback period of two to three years. The upgraded facility is expected to achieve cell efficiency of around 25%, up from the current average of 23.3%.

Furthermore, the company has shifted its planned 4 GW expansion phase from Andhra Pradesh to West Bengal. Management cited better synergies in terms of infrastructure, skilled manpower, and supply chain as key reasons for the change. Land approvals in West Bengal are expected within the current month, with construction slated to begin in mid-September. The company maintains that there will be no change in overall project timelines or capex plans.

What the Numbers Show

The divergence between revenue growth (70%) and EBITDA margin contraction (from 47% to 34%) highlights the company’s strategic pivot towards vertical integration. By doubling module production, Websol is capturing value further down the supply chain, albeit at lower initial margins compared to pure cell sales. However, the absolute growth in EBITDA confirms that volume leverage is offsetting the mix shift. Additionally, the complete repayment of the IREDA loan from internal accruals demonstrates strong cash generation capabilities, reducing financial risk and freeing up promoter equity for potential future strategic moves.
