Gautam Solar unveils 630 W TOPCon module for utility-scale solar projects

<p class="p1"><span class="s1">Gautam Solar has introduced 630 W R-Series tunnel oxide passivated contact (TOPCon) modules for utility-scale PV projects, approved under India’s Approved List of Models and Manufacturers (ALMM) and Bureau of Indian Standards (BIS).</span></p><p><strong>From <a href="https://www.pv-magazine-india.com/2025/09/22/gautam-solar-unveils-630-wp-topcon-module-for-utility-scale-solar-projects/" rel="noopener" target="_blank">pv magazine India</a></strong></p>
<p>Gautam Solar has unveiled its 630W 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.</p>
<p>Built on n-type TOPCon technology, the R Series modules deliver up to 23.32% module efficiency with a maximum power output of 630 W. Bifacial gain is up to 30% under optimal conditions.</p>
<p>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.</p>
<p>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.</p>
<p>Temperature coefficient is -0.29% per C, making the modules ideal for hot Indian climates. The module is certified to withstand a snow load of up to 5,400 Pa and wind load of up to 2,400 Pa.</p>
<p>“Our new 630 W 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,&#8221; said Gautam Mohanka, director of Gautam Solar. This milestone reinforces Gautam Solar’s commitment to delivering world-class solutions that drive India’s clean energy future.”</p>
