What is the TommaTech 620 Wp 144TNFB M10 Topcon Dark Series Solar Panel?
TommaTech 620 Wp 144TNFB M10 Topcon Dark Series Solar Panel, with its 620 Wp of power, is a member of the 10TNFB series in M144 format and uses N-type TOPCon technology. Its anti-reflective glass coating, which also helps the panel clean itself, aims to get better efficiency from the panel in low-light conditions such as morning and cloudy weather. The Dark Series name indicates the series that emphasises a dark, uniform look; it can be preferred on roofs where aesthetics matter.

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.
