Gautam Solar has announced that its 640 Wp R-Series TOPCon solar modules have received approvals from both the Approved List of Models and Manufacturers (ALMM) and the Bureau of Indian Standards (BIS).
With a module efficiency of up to 23.69%, the high-power R-Series modules enable greater energy yield within the same land area—making them ideal for utility-scale solar farms, where land optimization, energy yield, and cost competitiveness are key.
The high-power, high-efficiency design leads to lower Balance-of-System (BOS) cost per watt.
The module retains the advantages of n-type TOPCon technology — minimal Light Induced Degradation (LID) and Light and Elevated Temperature Induced Degradation (LETID), bifacial gain potential of up to 30%, and excellent performance under high temperature conditions.
