What is the TommaTech 425 Wp 108TNB M10 G2G TOPCon Solar Panel?
The TommaTech 425 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 425 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.

| Warranty | 15 years product, 30 years performance |
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
In Antalya, the panel surface heats up in summer months, and airborne dust, pollen and coastal salty humidity accumulate on the surface. The TUV Nord reports in the file include salt mist corrosion (IEC 61701), dust and sand (IEC 60068), ammonia corrosion (IEC 62716) and PID (IEC 62804) tests; you can download and review the relevant documents from the page. Solar Nexo carries out the entire process, from supplying the panel to project design, installation, commissioning and technical support. Theoretically, according to PVGIS data, 1 kWp produces about 1,656 kWh/year in Antalya; for a single 425 Wp panel, this comes to about 704 kWh/year (excluding shading, tilt and system losses).
