What Websol Energy does
Websol Energy System Limited is an India-incorporated, publicly listed solar photovoltaic manufacturer founded in 1994, operating as one of the country's earliest producers of solar cells. The company manufactures M10 (182mm) Bifacial Mono-PERC solar cells and 525-550 Wp bifacial solar modules at its Falta SEZ facility in West Bengal, with additional capacity additions in 2024-2025 (a 600 MW cell line commenced September 2025). Websol holds full ALMM List-I and List-II compliance alongside BIS, IEC 61215, and IEC 61730 certifications, positioning it for participation in government-backed schemes such as PM Surya Ghar, PM-KUSUM, and CPSU Phase-II. Revenue is generated through direct B2B sales of solar cells (priced INR 12.85-13.50/Wp) and modules (priced INR 21.00-24.00/Wp) to utility-scale project developers, EPC contractors, commercial and industrial customers, and OEM module manufacturers.
The company's go-to-market is enterprise-led, with direct field sales targeting large-volume and long-term supply contracts, supported by participation in industry exhibitions (Uttar Pradesh Energy XPO2026, RenewX 2026) and a digital presence across LinkedIn, YouTube, and trade publications. In late 2025, Websol initiated a major capacity expansion: an MoU with Linton Crystal Technologies for PV ingot manufacturing (backward integration toward ALMM List-III compliance by June 2028) and an MoU with the Andhra Pradesh Economic Development Board to anchor a planned ₹3,538 crore, 8 GW solar cell and module expansion at MPSEZ-Naidupeta. A planned TOPCon upgrade at Falta SEZ (targeting efficiencies above 24.5% by February 2027) signals a planned technology transition from P-type Mono-PERC to N-type architecture. Leadership is anchored by Managing Director Sohan Lal Agarwal (40+ years of manufacturing experience), Executive Director Sanjana Khaitan, and a board with deep sectoral credentials (NTPC, SECI, Power Grid, IIT Kanpur, Brown University).

Websol Energy competitors and assessment
Company assessmentBroad incumbents
- Trina Solar: Global Tier-1 solar module manufacturer with integrated cell+module production and TOPCon leadership. Comparable as a vertically-integrated PV manufacturer with overlapping product technology roadmap (N-type transition) and large-scale manufacturing expertise relevant to Websol's expansion plans.
- Tata Power Solar Systems: Tata Group subsidiary manufacturing solar cells and modules with strong EPC integration capabilities. Larger incumbent in Indian solar manufacturing serving utility-scale, C&I, and rooftop segments with comparable ALMM-listed product portfolio.
- LONGi Green Energy Technology: Global leader in monocrystalline silicon wafers, cells, and modules with leadership in BC and TOPCon technologies. Comparable as the technology benchmark Websol's M10 Mono-PERC and planned TOPCon lines are measured against (per Websol's own "G12 Technology Platform" benchmarking reference).
- First Solar: US-based thin-film solar module manufacturer with global utility-scale focus and Series 7 CdTe modules. Comparable as a major solar module manufacturer competing for utility-scale tenders, though using different cell technology (thin-film vs crystalline silicon).
- Jinko Solar: World's largest solar module manufacturer with integrated N-type TOPCon capacity. Comparable as a vertically-integrated PV manufacturer with benchmark scale and technology roadmap relevant to Websol's expansion ambitions.
- Adani Solar (Mundra Solar): Subsidiary of Adani Group, one of India's largest solar manufacturers with multi-GW integrated capacity including cells, modules, and planned ingot/wafer production. Larger incumbent competing in the same ALMM and government scheme markets with greater balance sheet capacity.
Direct peers
- Vikram Solar: Listed Indian solar module and cell manufacturer with comparable Mono-PERC and bifacial product lines serving utility-scale and rooftop markets. Direct competitor in ALMM-listed domestic supply and overlapping technology roadmap.
- Waaree Energies: India's largest solar module manufacturer with ~15 GW capacity, producing Mono-PERC and TOPCon modules and cells. Directly comparable as an ALMM-listed domestic manufacturer serving utility-scale, C&I, and government projects with overlapping technology and customer base.
- Premier Energies: Indian solar cell and module manufacturer with both P-type and N-type (TOPCon) capacity, competing in ALMM-listed domestic supply for government and utility-scale projects. Highly comparable in scale, technology, and customer focus to Websol.
Others
- Linton Crystal Technologies: PV ingot and wafer equipment/manufacturing partner with whom Websol signed an MoU (Dec 2025) for backward integration into ingots. Comparable as an adjacent ecosystem participant and key partner for Websol's ALMM List-III compliance roadmap rather than a direct competitor.
