Gautam Solar's TOPCon module
The module, developed with rectangular n-type TOPCon bifacial solar cells, optimizes energy production through enhanced cell packing density and dual-sided light absorption. According to Gautam Solar: “This smart design has a greater active area, which minimizes losses and enhances bifacial gain. It is considered very advantageous for large-scale ground-mounted solar installations, particularly in areas characterized by high albedo conditions.” The design is particularly suited for regions with reflective surfaces, boosting efficiency in utility-scale projects.
Available in five variants, the module delivers power outputs ranging from 620 W to 640 W, with power conversion efficiencies between 22.95% and 23.69%. It features an open-circuit voltage of 48.5 V to 49.3 V and a short-circuit current from 16.16 A to 16.35 A. Measuring 2,382 mm x 1,134 mm x 30 mm and weighing 33.1 kg, the panel includes an IP68-rated junction box, 2.0 mm tempered glass, and an anod Eurized aluminum alloy frame. Its temperature coefficient is -0.29%/C, ensuring stable performance in varying climates.
Gautam Solar emphasized the module’s durability: “The panel performs better; lower degradation rates, excellent temperature coefficient, and confirmed higher output even under low-light conditions characterize the module.” These attributes make it resistant to potential-induced degradation (PID), weatherproof, and capable of withstanding significant mechanical loads, ideal for challenging environments.
The product comes with a 12-year product warranty and a 30-year performance warranty, offering long-term reliability for solar installations. Gautam Solar, headquartered in New Delhi, operates manufacturing facilities in Uttarakhand and Haryana. The company plans to expand its solar module production capacity to 5 GW in the fiscal year 2025-26, supporting India’s growing renewable energy demands.
The launch event attracted industry professionals, who noted the module’s potential to enhance large-scale solar projects. Gautam Solar’s innovation aligns with global sustainability goals, providing efficient and robust solutions for clean energy generation.
