What is the TommaTech 420 Wp 108TNB M10 G2G TOPCon Solar Panel?
The TommaTech 420 Wp 108TNB M10 G2G TOPCon Solar Panel combines a double-glass (G2G) structure laminated with two layers of EVA with bifacial TOPCon technology in a panel rated at 420 Wp. Double glass means that both the front and rear sides of the panel are glass, and it is taken into account in projects with demanding environmental conditions.

Double glass laminated with two layers of EVA, a specially coated anti-reflective surface and a 0~+5 W positive tolerance are the highlights of this series. A 15-year product and 30-year performance warranty is defined.
Which projects is it suitable for?
The bifacial structure makes particular sense on open roofs, ground-mounted systems and buildings with light-colored roof surfaces. In residential, agricultural and commercial rooftop projects, the rear-side gain varies depending on mounting height and ground reflection.
Use in Antalya and Solar Nexo support
On the coast, salty air and summer humidity are a real factor for rooftop equipment. The documentation set provided for this model includes TUV Nord reports on IEC 61701 salt mist, IEC 60068 dust-sand, IEC 62716 ammonia and IEC 62804 PID. Solar Nexo undertakes the site survey, project design, installation and commissioning in Antalya; the datasheet can be downloaded from the page. Theoretically, according to PVGIS data, 1 kWp produces about 1,656 kWh/year in Antalya; for a single 420 Wp panel, this comes to about 696 kWh/year (excluding shading, tilt and system losses).
