New Delhi: Portraying its energy prowess in the clean energy revolution across the globe, Gautam Solar, for the first time in India, is showcasing its advanced and transforming N-type TOPCon (Tunnel oxide passivated contact) Solar Modules at the Renewable Energy India (REI) Expo 2023 from 4th to 6th October.

Gautam Solar’s revolutionary N-type TOPCon Solar Modules will be available in the 565 – 580 Wp wattage range. These modules are best suited for ground-mounted projects and have a maximum efficiency of 22.45%. These modules have been certified as per UL & IEC Standards and are already available for the US and European markets.

TOPCon is a state-of-the-art Solar Module Production Technology in which a thin tunnelling oxide layer is applied on an N-type silicon substrate, followed by a layer of highly doped Poly Silicon and Passivated Contacts. The tunnel oxide layer allows charge carriers to pass while minimising recombination losses. The passivated contacts reduce surface recombination.

In N-type Cells, the base silicon layer is doped with Phosphorous instead of Boron, like in P-type Cells. As a result of this, free electrons are generated, which increases the efficiency of the cells and, hence, the resulting modules.

Because of this difference, Gautam Solar’s N-type TOPCon Solar Modules offer 5% more power every year compared to P-type Solar Modules on account of the increased cell efficiency.

Gautam Solar’s N-type TOPCon Solar Modules also have lower degradation rates of 1 per cent in the first year and 0.4 per cent in subsequent years, unlike 2 per cent in the first year and 0.55 per cent in subsequent years for P-type Modules. This increases the longevity of the solar modules. It degrades only to 87.4% of its initial rated power at the end of 30 years compared to P-type modules, which degrade to 84.8% in their 25-year lifecycle.

In addition to the above, Gautam Solar’s N-type modules also provide BOS Cost Savings of 3.26 per cent and LCOE reduction of 1.56 per cent.

These modules are based on M10 Cells and are composed of 144 half-cut cells produced using a Non-Destructive Cutting Process for better low-light performance and negligible chances of micro-cracks.

Additionally, they feature a multi-busbar design with round ribbon connectors for lower electrical losses and better light utilisation. The modules will be available in both Monofacial and Bifacial variants, with the latter providing an additional 10-30% power from the rear side, depending on the installation conditions.

“Our endeavour has always been to leverage technological innovations to develop products that will holistically transform the solar energy landscape. As one of the few Indian Companies to have secured patents and IPs for our work in the Solar Industry, the focus on the latest technology has been the cornerstone of Gautam Solar’s product offerings, and our N-type TOPCon Solar Modules are the latest addition to that list,” noted Gautam Mohanka, CEO of Gautam Solar.

Gautam Solar added an A+ grade production line with N-type TOPCon machines from a leading equipment supplier, becoming only the second company in India to do so at its state-of-the-art factory in Haridwar.
