What is the TommaTech 620 Wp 144TNB M10 G2G TOPCon Solar Panel?
TommaTech 620 Wp 144TNB M10 G2G TOPCon Solar Panel is an N-type TOPCon solar panel model with an output of 620 Wp. In the model code, 144TNB indicates the series and M10 the cell format. The special coating on the glass surface reduces reflection and helps limit dust build-up; the panel is also designed to work efficiently in low-light morning hours and in cloudy weather. The G2G structure, with glass on the front and back, is laminated with two layers of EVA.

Which projects is it suitable for?
With 620 Wp of power, this model suits large commercial roofs, greenhouse and agricultural irrigation PV systems and ground-mounted applications. Thanks to the high wattage, a given capacity can be installed with fewer panels, which shortens installation time. On small residential roofs, dimensions and weight should be assessed together with the datasheet.
Use in Antalya and Solar Nexo support
In Antalya, about 1,656 kWh/year of production per kWp installed is theoretically expected according to PVGIS data; with this value, the theoretical annual output of a single 620 Wp panel is about 1027 kWh (no shading, suitable tilt). Because high summer temperatures reduce panel efficiency somewhat, the temperature coefficient and ventilated mounting are important. The documents include TÜV Nord test reports on PID (IEC 62804), salt mist corrosion (IEC 61701), dust and sand (IEC 60068) and ammonia corrosion (IEC 62716); it is useful to review these reports for projects close to the coast.
The Solar Nexo team handles the whole process, from supplying the panel through design, installation on the roof or in the field and commissioning to later technical support. The technical datasheet can be downloaded from this page; you can contact us for a site survey and a quote.
