Gautam Solar TOPCon modules receive BIS certification


Gautam Solar announced this week its latest TOPCon PV modules are now certified by the Bureau of Indian Standards (BIS) and thus eligible for PV projects in India. The modules are already certified as per UL and IEC standards and comply to requirements in the US and European markets.

“The main advantage of Gautam Solar’s 590 Wp TOPCon solar module is that it has the same size as a 550 Wp mono PERC panel and still offers a higher efficiency and produces approx. 5% more energy per year than normal mono PERC solar modules. These modules degrade only up to 87.4% of their initial rated power at the end of 30 years compared to normal mono PERC modules which degrade to 84.8% in their 25-year lifecycle. The modules provide BOS cost savings of 3.26% and LCOE reduction of 1.56% over the existing technology,” stated Gautam Solar.

The modules were showcased at the Renewable Energy India (REI) Expo in October 2023.

Gautam Solar’s TOPCon 590 Wp modules offer energy conversion efficiency of up to 22.84% and optimized bifacial power generation performance. The degradation rate is 1% in Year 1 and 0.4% subsequently, as opposed to 2% in Year 1 and 0.55% subsequently for normal mono PERC modules. This increases the longevity of the modules. The modules are built with multi-busbar (MBB) technology with round ribbons for lower electrical losses and higher light utilization and non-destructive cutting technology for lower chances of micro-cracks and greater mechanical strength.
