Websol Energy Charts G12R Foray In FY27 Amid Strong DCR Demand Photograph: (Archive)
West Bengal-based solar cell and module manufacturer Websol Energy System Ltd is planning to foray into G12R solar cell manufacturing from FY27. Buoyed by the plum order book and rising demand for DCR solar cells, the leadership recently told investors about its plan to foray into the production of G12R wafer-based solar cells, which have picked up demand in the Indian market recently. 
The management indicated that one of its existing lines will be ramped up to the new format by the middle of next year, as the company looks to align with evolving technology trends in photovoltaic manufacturing.
“At the moment we don’t have, but then we will be ramping one of the lines to G12R by the middle of next year,” Vasanthi Sreeram, Chief Technical Officer (CTO) of the organisation, told investors. The move marks a transition for the West Bengal-based solar cell and module manufacturer, which currently operates 1.2 GW of cell capacity focused on DCR (Domestic Content Requirement) production. The proposed shift to G12R cells is expected to enhance product competitiveness and efficiency levels, while supporting the company’s longer-term integration strategy.
This comes at a time when most Indian solar cell manufacturers have already shifted to G12R-based technology, or are planning to do so shortly, to meet rising demand. G12R-based modules are enabling higher-efficiency solar panels exceeding 600 Wp, reducing capital costs for developers and consumers while increasing energy yield. This, in turn, lowers land requirements and the need for balance-of-system equipment.
The company reported an order book of approximately ₹1,150 crore as of December 31, 2025, with modules accounting for 57% and cells contributing 43%, providing balanced visibility across its manufacturing segments.
Operationally, Websol’s cell manufacturing lines continued to see strong utilisation. Cell Line-1 operated at 97% utilisation, while Cell Line-2, commissioned in September 2025, reached 54% utilisation during its ramp-up phase. On the module side, capacity utilisation stood at 64% in the third quarter of FY26, the management said. 
The company also highlighted its execution capabilities, noting that its second 600 MW Mono PERC cell line was commissioned in under a year and fully funded through internal accruals. The line has already achieved peak cell efficiency of 23.6% within three months of commissioning.
During the quarter, Websol secured approval for a proposed 4 GW integrated solar cell and module manufacturing facility in Andhra Pradesh. Land allotment has been completed, and the project has received a customised incentive package, including investment-linked subsidies, from the Andhra Pradesh Economic Development Board.
In line with its backward integration strategy, the company has entered into a memorandum of understanding with Linton, a global provider of photovoltaic ingot and wafer equipment technology, to evaluate the feasibility of establishing local manufacturing of PV ingots and wafers in India. The initiative is currently in the technical evaluation and research phase.
Websol remains focused on the domestic DCR segment, with no current exposure to non-DCR or export markets. Management said the DCR market continues to offer favourable pricing and margins, supported by strong domestic demand. The company also highlighted its differentiated positioning, with higher cell capacity relative to module capacity, which it said supports superior margins compared to industry peers, where module capacities typically exceed cell capacities.
