1. At a Glance
Websol Energy System Ltd makes solar cells and modules in Falta, West Bengal, and in the June 2026 quarter it made rather a lot of them: 259 MW of cells and 103 MW of modules, against 126 MW and 50 MW a year earlier. Revenue from operations came in at ₹372.60 crore, up 70.3% year-on-year. PAT was ₹77.79 crore, up 15.8%. EBITDA — which the company reports excluding other income — was ₹126 crore, up 21.4%, at a margin of 33.7% versus 47.3% in Q1 FY26.
Then the quarter ended and August happened. On 4 August the company repaid its entire outstanding IREDA term loan of ₹110 crore from internal accruals. On 10 August the board approved the results, appointed two directors, accepted one director’s unwillingness to stand for reappointment, and hired a new Company Secretary — a single afternoon of board meeting that ran from 1:45 p.m. to 4:30 p.m. and appears to have used every minute of it.
Elsewhere on the record: the confirmed order book stood at ₹1,278 crore as of 30 June 2026, up from ₹1,161 crore at March-end. A 600 MW Mono PERC cell line is being upgraded to a 750 MW TOPCon line at a cost of about ₹270 crore, targeted for March 2027. And the site of the planned 4 GW greenfield expansion moved from Andhra Pradesh to West Bengal — a relocation of roughly 1,700 kilometres, executed with no financial outflow on the Andhra land, which is the corporate equivalent of cancelling a hotel booking inside the free-cancellation window.
The margin line is the one that moved most. Management has an explanation, and it is a mix explanation.
2. Introduction
The Websol group was incorporated in 1990 by Mr. Sohan Lal Agarwal and has been in solar PV manufacturing since 1994, which makes it one of India’s earliest entrants into a business that most of India ignored for the following two decades. The company’s presentation traces peak output per cell from 1.1 Wp in 1994 to an expected 9.5 Wp in 2027 — a tenfold improvement achieved by a company that spent large parts of that journey being, financially speaking, extremely quiet.
Quiet is putting it kindly. Sales were ₹17.22 crore in FY23 and ₹25.86 crore in FY24 — figures more commonly associated with a mid-sized restaurant chain than a solar cell plant. Crisil’s rating rationale attributes the FY23 and FY24 production and margin trough to the transition out of multicrystalline cells into monoperc, with the new technology commencing operations from February 2024.
What followed was steep. FY25 sales were ₹575.46 crore. FY26 sales were ₹1,049.44 crore. In September 2025 the second 600 MW Mono PERC line commenced production, doubling cell capacity to 1.2 GW; module capacity stands at 550 MW. Crisil, assigning ‘Crisil BBB+/Stable’ to ₹150 crore of bank facilities in December 2025, described the company as having an established market presence with a market share of around 10% in solar cell manufacturing.
The corporate calendar since has been busy: a 1:10 stock split in November 2025, an MoU with Linton Crystal in December 2025 to explore PV ingot and wafer manufacturing, a CIT(Appeals) order in December 2025 annulling a ₹73.04 crore tax demand for FY2016-17, and warrant conversion in March 2026 allotting 1.21 crore shares for ₹48.10 crore. The Andhra Pradesh 4 GW project, approved by that state in January 2026, has since been redirected to West Bengal.

3. Business Model: WTF Do They Even Do?
Websol manufactures photovoltaic crystalline solar cells and the modules that hold them. That is the whole business — Ind AS 108 disclosure confirms a single operating segment, which is refreshingly free of the “diversified conglomerate” energy that afflicts so much of listed India.
The physical arrangement is roughly this: silicon wafers arrive, get processed into Mono PERC cells at a facility spanning about 7 acres in the Falta Special Economic Zone, and then either leave as cells or get soldered into modules on the same campus. Of 259 MW of cells produced in Q1 FY27, about 153 MW were sold externally; the balance was consumed captively or held. So the company is partly its own customer, which means a cell can be sold to the module division without ever leaving the property — the shortest supply chain in Indian manufacturing, measured in metres.
Cell efficiency currently averages around 23.3%, with Mono PERC lines at 90%+ utilisation. Efficiency is the entire sport here: the same square of silicon either converts 23.3% of the sunlight hitting it or it doesn’t, and a fraction of a percentage point is what separates a competitive line from a museum exhibit. The upgraded TOPCon line targets around 25%.
Where the output goes is a policy question as much as a commercial one. Management stated on the August call that Websol supplies “mostly DCR projects,” naming PM-Surya Ghar and PM-KUSUM. The presentation notes the company is one of 14 ALMM-approved solar cell manufacturers in India. Domestic Content Requirement tenders can only use domestically made cells, which turns an approval list into a customer list.
Realisations, as disclosed: Q1 cell realisation was around USD 0.125 per watt-peak, module realisation around ₹20.50 per watt. Current cell prices were described as hovering around USD 0.13 per watt. A business is therefore priced in fractions of a cent per
