Gautam Solar Unveils 630 Wp R Series TOPCon Solar Modules with ALMM & BIS Approvals for Utility Scale Project

Gautam Solar, one of India’s leading solar module manufacturers, has unveiled its 630Wp R-Series TOPCon Solar Modules, engineered for higher efficiency, durability, and superior energy yield. 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. Designed with 182mm x 210 mmwafers, rectangular cell, half-cut technology, and multi-busbar (MBB) technology, these modules significantly reduce resistive losses and maximize system performance.

Key Technical Highlights of the 630 Wp R Series TOPCon Modules

• High Power Output:630 Wp per module for optimized BOS cost and IRR improvement.
• Efficiency Leader: Module efficiency up to 23.32%, outperforming PERC modules.
• Bifacial Design:Approx. 30% bifacial gain under optimal conditions,
• Long-Term Reliability:
  • First-year degradation <1%.
  • Annual degradation ≤0.4%.
  • Low LID/LeTID due to N-type cells.
• Temperature Coefficient: -0.29%/°C, ideal for hot Indian climates.
• Durability Tested: 5400 Pa snow load / 2400 Pa wind load certified.
• Certified & Approved:ALMM-listed (MNRE)&BIS-certified (IS 14286/IS 61730) for Indian projects.

Commenting on the launch, Mr. GautamMohanka, Director, Gautam Solar Pvt. Ltd., 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.”

By introducing TOPCon technology, Gautam Solar continues to align with India’s 500 GW renewable energy target by 2030, while supporting international markets with advanced, certified solar solutions.
