The module was inaugurated by Mohammad Rihan, Director General, National Institute of Solar Energy (NISE), in the presence of Neelesh Garg, Chairman and Managing Director; Manik Garg, Managing Director; Prashant Mathur, Chief Executive Officer; and Pushpendra Samadhiya, Chief Revenue Officer of Saatvik Green Energy.
Built on N-type TOPCon 3.0 cell architecture, the module features a bifacial double-glass construction. Under standard bifacial rating conditions (BNPI), its output can reach up to 745 W, accounting for additional power generation from the rear side of the module.
Commenting on the launch, Prashant Mathur, Chief Executive Officer, Saatvik Green Energy, said, “As India’s solar sector scales up, the focus is shifting towards higher-efficiency modules that can improve project economics while delivering reliable, long-term performance. Our Quad-Cut TOPCon 3.0 Dual Glass Bifacial Module reflects Saatvik’s commitment to advancing solar technology through products that combine higher power output, optimised system costs and long-term performance assurance. Backed by advanced N-type TOPCon 3.0 technology and a robust warranty structure, the module is designed to address the evolving needs of India’s utility-scale and commercial solar markets.”
The module uses a quad-cut, or quarter-cut, cell design comprising 264 cells arranged in a 6 × 44 configuration. According to the company, the design reduces current loss per cell, helping lower resistive losses, minimise hot-spot risks and extend module life. Its higher power output is intended to help project developers reduce the number of modules required for a given capacity and lower balance-of-system costs associated with mounting structures, cabling, land use and installation.
The module has a maximum power temperature coefficient of -0.26%/°C, which is designed to limit output losses at higher operating temperatures.
Saatvik Green Energy is offering a 12-year product warranty and a 30-year linear power warranty for the module. The warranty terms provide for one percent degradation in the first year and annual degradation of 0.35 percent thereafter, with the module guaranteed to retain at least 88.85 percent of its rated power at the end of 30 years. The warranty is supported by Munich Re insurance.
