SLR Solar Secures 1,020 MW ALMM Approval for TOPCon Modules, Plans Cell and BESS Manufacturing Expansion
SLR Solar has secured approval under the Approved List of Models and Manufacturers (ALMM) List-I for 1,020 MW of bifacial N-Type TOPCon solar module manufacturing capacity, marking a significant milestone in the company’s expansion and vertical integration strategy.
The approval covers SLR Solar’s SLR-HG132N series of glass-to-glass modules, manufactured at its facility in Bargaon, Kishangarh, on the Jaipur Highway (NH-8). The modules use 132 half-cut G12R cells and are available in power ratings ranging from 610 Wp to 650 Wp. The ALMM approval is valid from August 2026 to August 2030.
According to Kamal Yadav, Director, SLR Solar, the company selected the G12R rectangular wafer format to support utility-scale solar deployment through higher power density, lower balance-of-system costs, and strong bifacial performance. The technology is increasingly being adopted as developers seek to reduce the levelised cost of electricity (LCOE) while optimising land utilisation.
Following the ALMM approval, SLR Solar plans to expand its manufacturing capabilities by entering G12R solar cell manufacturing. The move forms part of the company’s backward integration strategy and is aimed at reducing dependence on imported cells while improving control over product quality, costs, and delivery timelines.
The company sees domestic cell manufacturing as increasingly important as India’s domestic content requirements become more stringent and the solar industry moves towards greater local value addition.
Alongside its plans for cell manufacturing, SLR Solar is also evaluating the establishment of a Battery Energy Storage System (BESS) manufacturing line.
The proposed expansion is intended to address the rising demand for integrated solar-plus-storage solutions as utilities and renewable energy developers increasingly adopt hybrid projects. Energy storage is expected to play a growing role in making renewable power more dispatchable and improving grid flexibility.
SLR Solar views the move towards modules, cells, and storage as part of a broader shift in India’s solar manufacturing industry towards end-to-end vertical integration.
The company expects policy measures, including PLI schemes, ALMM requirements, and customs duty structures, to continue encouraging domestic manufacturing and value addition across the renewable energy supply chain.
With its latest ALMM approval and plans for cell and BESS manufacturing, SLR Solar is positioning itself to expand beyond module assembly and build a more integrated clean energy manufacturing ecosystem in India.
