Grew Solar has applied for inclusion of its three point five gigawatt (GW) TopCon G12R solar cell manufacturing capacity at its Narmadapuram facility in Madhya Pradesh under the Ministry of New and Renewable Energy Approved List of Models and Manufacturers List-II for N?Type TopCon solar photovoltaic cells. The application comes as ALMM List-II came into force on the first of June and domestic TopCon cells and modules are reported to be in short supply. The move aims to secure regulatory recognition and support for locally made cells.

Industry sources indicate most manufacturers have struggled to maintain capacity utilisation above 70 per cent, which has contributed to upward pressure on prices. The company proposal arrives amid forecasts that fresh capacities of over six gigawatt (GW) may be added by September, which are expected to ease tightness by December 2026. The report notes that capacity additions could improve plant utilisation and market balance towards the end of the year.

The G12R wafer format, also known as 210R, is being regarded as the next evolution following the widely adopted M10 format and is said to offer higher module efficiency, lower production costs and improved line utilisation. Manufacturers consider the format helpful in narrowing the gap between nameplate capacity and actual output, thereby enhancing overall plant performance. This technical shift is influencing investment and manufacturing strategies across the sector.

The ALMM framework has been introduced to promote quality, reliability and traceability in the Indian solar sector while encouraging domestic manufacturing capacity. Grew Solar's application is presented as part of broader efforts to build a self?sufficient renewable energy ecosystem and to secure market share for locally produced modules and cells. Observers expect that certification under ALMM List?II may support procurement by projects that require approved models.

Solar cells remain the core building blocks of photovoltaic modules and are central to determining system efficiency and long?term sustainability. The company application and ongoing format transition underline how manufacturing upgrades and regulatory alignment are shaping the domestic solar manufacturing landscape.
