What is the TommaTech 645Wp 132TNBR M12 TOPCon Solar Panel?
TommaTech 645Wp 132TNBR M12 TOPCon Solar Panel is an N-type TOPCon solar panel model with 645 Wp output power. In the model code, 132TNBR denotes the series and M12 the cell format. The special coating on the glass surface reduces reflection and helps limit dust build-up on the surface; the panel is also intended to work efficiently in low-irradiance morning hours and in cloudy weather.

Which projects is it suitable for?
With 645 Wp of power, this model suits large commercial roofs, greenhouse and agricultural irrigation PV plants, and ground-mounted installations. Thanks to its high wattage, a given capacity can be installed with fewer panels, which shortens installation time. On small residential roofs, the dimensions and weight should be assessed together with the datasheet.
Use in Antalya and Solar Nexo support
In Antalya, one kWp of installed capacity is theoretically expected to produce about 1,656 kWh/year according to PVGIS data; at this rate, the theoretical annual output of a single 645 Wp panel is about 1068 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); for projects near the coast, it is useful to review these reports.
The Solar Nexo team carries out the entire process, from supplying the panel and designing the project to installation on the roof or on the ground, commissioning and later technical support.
