What you need to know about the TommaTech 620 Wp 144TNB M10 Topcon Solar Panel
With a power of 620 Wp, the TommaTech 620 Wp 144TNB M10 Topcon Solar Panel comes from TommaTech's family of panels with N-type TOPCon cells. The 144TNB series code and M10 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
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.
