What is the TommaTech 620 Wp 132TNBR M12 TOPCon Solar Panel?
With a power of 620 Wp, the TommaTech 620 Wp 132TNBR M12 TOPCon Solar Panel comes from TommaTech's family of panels with N-type TOPCon cells. The 132TNBR series code and M12 format distinguish it from other power classes in the same family. The special coating on the glass reduces reflection, helps limit dust adhesion and aims for high efficiency even in weak light.

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.
