Solarium Green Energy re-enters solar module manufacturing with 1 GW TOPCon factory in Gujarat
It targets the in-house EPC requirement for residential rooftop EPC business amid the DCR requirement for government schemes
The company also plans to start manufacturing mounting structures at its Bavla location
Indian residential rooftop solar service provider Solarium Green Energy has come back to solar module manufacturing with the announcement of a 1 GW production factory in Ahmedabad, Gujarat.
The planned factory will produce crystalline silicon TOPCon solar PV modules using half-cut cells and bifacial solar cells, and imported tabber-stringers, laminators, and sub simulators. It will be set up as a fully automated factory for an estimated CapEx of INR 700 million ($8 million). The factory is targeted to come online in the last quarter of FY 2025-26.
Additionally, the company is also venturing into mounting structures production at its existing factory in Bavla, also in Gujarat.
Solarium entered solar module manufacturing at Bavla in 2018, but its polycrystalline modules did not make it to the Ministry of New and Renewable Energy’s (MNRE) Approved List of Models and Manufacturers (ALMM) List-I, hence it shut down the factory in February 2024 (see India Solar PV News Snippets: Jupiter To Expand Solar Cells & Module Capacity & More).
The company plans to re-enter module manufacturing to serve its own EPC projects with domestically manufactured solar panels.
Solarium had to delay about INR 170 million ($2 million) of residential rooftop orders to Q1 of FY 2025-26, citing a lack of DCR modules.
It explained, “The manufacturing facility is aimed at mitigating supply chain risks arising from trade-related disruptions, geopolitical uncertainties, and price volatility. By securing in-house production of solar modules, the company seeks to ensure the timely availability of this critical component, thereby safeguarding the execution timelines and cost efficiency of its long-term EPC projects.”
The module factory will also strengthen its bidding capabilities across B2G and B2B segments, as the management cites growing demand for domestically produced solar modules in the residential rooftop segment. Under the government’s PM Surya Ghar: Muft Bijli Yojana, the government targets 30 GW of installed solar capacity through the scheme by March 2027 (see India Calls For Innovative Proposals Under PM Surya Ghar Scheme).
Excess solar module capacity produced by its Gujarat factory will be sold to other EPC players or the B2B segment.
Gujarat leads the country’s total solar module and cell production capacity, which reached 25.3 GW and 11.6 GW at the end of 2024, according to Mercom India Research (see India’s Solar PV Manufacturing Capacity Improved By 37 GW In 2024).
