Gautam Solar has unveiled its 630Wp R-Series TOPCon solar modules for utility-scale PV projects. The new modules are ALMM and BIS approved, ensuring compliance for government projects and large-scale tenders, while meeting the highest industry standards.
Built on n-type TOPCon (tunnel oxide passivated contact) technology, the R Series modules deliver up to 23.32% module efficiency with a maximum power output of 630 Wp. Bifacial gain is up to 30% under optimal conditions.
Gautam Solar said the modules are designed with 182mm x 210 mm wafers, rectangular cell, half-cut technology, and multi-bus bar technology, significantly reducing resistive losses and maximize system performance.
The company added that the module degradation is less than 1% in the first year with an annual linear degradation rate of ≤0.4% in subsequent years.
Temperature coefficient is -0.29%/°C, making the modules ideal for hot Indian climates. The module is certified to withstand snow load of up to 5,400 Pa and wind load of up to 2,400 Pa
Commenting on the launch, Gautam Mohanka, Director, Gautam Solar, said:
“Our new 630 Wp R Series TOPCon solar modules, with ALMM and BIS approvals, empower EPCs and developers with bankable, high-performance technology that complies with Indian tender requirements while reducing LCOE. This milestone reinforces Gautam Solar’s commitment to delivering world-class solutions that drive India’s clean energy future.”
