What is the TommaTech 715Wp 108TNB M12 G2G TopCon Diamond Plus Solar Panel?
TommaTech 715Wp 108TNB M12 G2G TopCon Diamond Plus Solar Panel is the bifacial glass-glass (G2G) model of the TommaTech Diamond Plus series, reaching 715 Wp with rear-side gain. The series definition states 625-610 Wp from the front side and a maximum of 745-715 Wp with rear-side gain.
The models one power class below and one above in the same series share the technology; the difference is the nominal power. A high Wp means more DC power with the same number of panels. For a system of about 10 kWp, 14 of these panels are needed (arithmetic; varies with roof layout).
Key technical specifications
- Model: 108TNB, M12 cell size, glass-glass (G2G) TOPCon
- Power: 745-715 Wp with rear-side gain in the series definition, 625-610 Wp from the front side
- Glass surface: special coating that reduces reflection and dust build-up
- Low light: targets high efficiency in the morning and in cloudy weather
- Warranty: 15-year product, 30-year performance warranty
Which projects is it suitable for?
It is a suitable panel type for commercial roofs, factories and ground-mounted systems where the ground or a light-colored roof surface reflects light onto the rear side. It can also be used in homes; because rear-side gain depends on mounting height and the surface beneath, expectations are clarified at the site survey.
Use in Antalya and Solar Nexo support
According to PVGIS data, 1 kWp of installed power produces about 1,656 kWh per year in Antalya (theoretical). Accordingly, roughly 715 kWh per year is expected from a single 1,184 Wp panel; actual production varies with shading, tilt, temperature and soiling. The fact that production peaks at the hours when air-conditioning load rises in summer is an advantage for self-consumption.
The document list includes the panel datasheet, two separate Diamond Plus CE certificates and the TommaTech CE certificate; these records should be reviewed for a system that will operate for many years in a hot, sunny climate.
Solar Nexo takes on every step from supply to design and from installation to commissioning; technical support continues after installation as well. The panel's datasheet and documents can be downloaded from the product page.
