Gautam Solar Unveils ALMM & BIS Approved 630 Wp R Series TOPCon Solar Modules

Gautam Solar, a solar module manufacturer, has unveiled its 630Wp R-Series TOPCon Solar Modules, developed for higher efficiency, durability, and energy yield. In a press release, while sharing these details, Gautam Solar said, “The new modules are ALMM and BIS approved, ensuring compliance for government projects and large-scale tenders, while meeting the highest industry standards.”

The release adds that the solar modules are based 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 mm wafers, rectangular cell, half-cut technology, and multi-bus bar (MBB) technology, these modules significantly reduce resistive losses and maximize system performance.

Key Technical Highlights 

• 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, Gautam Mohanka, 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.”

Earlier this year, Gautam Solar received UL Listing and Certification for its N-Type TOPCon solar modules in the United States (US) and Canada. This certification confirms full compliance with electrical codes and safety standards across North America and covers modules ranging from 560 Wp to 600 Wp (144 cells). The UL Listing enhanced Gautam Solar’s global credibility, signaling that its modules meet benchmarks for electrical safety, structural durability, environmental resilience, and long-term reliability, the firm said in a media statement.

Currently, it has planned an investment of around ₹4,000 crore to set up a 5 GW solar cell manufacturing facility in Gwalior, Madhya Pradesh. The project, spanning 54 acres, will focus on producing advanced TOPCon solar cells. Phase 1 of the project is already underway, with a 2 GW capacity expected to be operational by 2026. Following the completion of Phase 1, Gautam Solar plans an initial public offering (IPO) to fund Phase 2, which will add another 3 GW of capacity. The company also aims to expand into solar wafer manufacturing, creating a fully integrated domestic solar value chain.
