What is the TommaTech 615 Wp 144TNB M10 G2G TOPCon Solar Panel?
TommaTech 615 Wp 144TNB M10 G2G TOPCon Solar Panel is an N-type TOPCon solar panel model with an output of 615 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?
615 Wp class; a balanced choice for villas and detached houses, small businesses, agricultural irrigation systems and hybrid or grid-connected installations such as vineyard houses. It can also be used on commercial roofs and in the field with multiple strings, as suited to the array design.
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 615 Wp panel is about 1018 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.
