The 640 Wp R-Series modules are designed to deliver high-efficiency performance, enabling greater energy yield within the same land area, making them ideal for EPCs and developers looking to maximise returns. As one of India’s higher-wattage offerings, these modules are specifically developed for next-generation solar plants, empowering large-scale solar projects with reliable and high-performance technology.
Gautam Solar’s 640 Wp TOPCon R-Series modules offer best-in-class performance with a peak output of 640 Wp and module-level efficiency of up to 23.69%, positioning them ahead of most competing modules. Their high wattage and efficiency enable superior power density and area yield, generating more energy per square meter and optimizing land use. The design also reduces Balance-of-System (BOS) costs and lowers the Levelized Cost of Energy (LCOE), making the modules cost-effective for large-scale installations. Engineered for utility and ground-mounted solar projects, these modules combine high performance with bankable long-term reliability, benefiting from N-type TOPCon technology that minimises LID/LeTID, ensures lower degradation rates, provides bifacial gain potential of up to ~30%, and maintains superior performance under elevated temperatures.
Gautam Solar will be showcasing the 640 Wp R-Series modules at the REI Expo 2025, allowing visitors to experience the latest in high-efficiency solar technology first-hand.
Speaking on the development, Gautam Mohanka, Director of Gautam Solar, stated, "Achieving ALMM and BIS approvals for our 640 Wp R-Series modules is a major validation of our engineering, quality and manufacturing excellence. We are committed to not only adhering to the highest quality and compliance standards set by the Government of India, but also going beyond them in our offerings to ensure maximum customer satisfaction and advance India's goal of becoming a world leader in solar power production.”
These approvals have enabled Gautam Solar to contribute to the government’s ambitious renewable energy and sustainability goals and assist it in becoming a leader in solar power production.
