What you need to know about the TommaTech 620 Wp 132TNBR M12 G2G TOPCon Solar Panel
TommaTech 620 Wp 132TNBR M12 G2G TOPCon Solar Panel is an N-type TOPCon solar panel model with an output of 620 Wp. In the model code, 132TNBR indicates the series and M12 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. Because the rear side also generates energy, there is potential for extra yield in installations close to the ground or with reflective surfaces.

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
Antalya's long, sunny summer season means high production potential for this panel: according to PVGIS, 1 kWp theoretically produces about 1,656 kWh per year, so for a 620 Wp module this figure comes to about 1027 kWh. Because cell temperature rises in hot weather, leaving air circulation behind the panel is recommended. 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.
Solar Nexo supplies this model and offers system design, installation, commissioning and technical support for your project under one roof. You can access the datasheet from the documents section on the page and request a quote for your project.
