What you need to know about the TommaTech 640Wp 132TNBR M12 G2G TOPCon Solar Panel
TommaTech 640Wp 132TNBR M12 G2G TOPCon Solar Panel is an N-type TOPCon solar panel model with 640 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. The G2G construction, with glass on both the front and the back, is laminated with two layers of EVA. Because the rear side also generates energy, there is potential for additional gain in installations close to the ground or over reflective surfaces.

Which projects is it suitable for?
With 640 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
Antalya's long, sunny summer season means high generation potential for this panel: according to PVGIS, 1 kWp theoretically produces about 1,656 kWh per year, so for a 640 Wp module this figure comes to about 1060 kWh. Because cell temperature rises in hot weather, it is recommended to leave air circulation behind the panel. 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.
Solar Nexo supplies this model and offers system design, installation, commissioning and technical support for the project under one roof. You can reach the datasheet from the documents section of the page and request a quote for your project.
