What is the TommaTech 440 Wp 108TNB M10 TOPCon Solar Panel?
TommaTech 440 Wp 108TNB M10 TOPCon Solar Panel is a 440 Wp bifacial TOPCon panel. Able to collect energy from reflected light reaching its rear surface as well, this 108TNB series offers extra gain potential in installations with good reflection, such as ground-mounted or open roofs.
Key technical specifications
| Feature | Value |
|---|---|
| Nominal power | 440 Wp |
| Model code | 108TNB M10 |
| Cell technology | N-type TOPCon |
| Power tolerance | 0~+5 W |
| Wind / snow load | 2400 Pa / 5400 Pa |
| Face structure | Bifacial |
| Warranty | 15 years product, 30 years performance |
A special glass coating helps reduce surface dust, efficiency is maintained in low light, and the power tolerance is between 0 and +5 W. The manufacturer states a 15-year product and 30-year performance warranty.
Which projects is it suitable for?
The bifacial structure makes particular sense on open roofs, ground-mounted systems and buildings with light-colored roof surfaces. In residential, agricultural and commercial rooftop projects, the rear-side gain varies depending on mounting height and ground reflection.
Use in Antalya and Solar Nexo support
Antalya's long sunshine duration and hot summers make durability and temperature behavior important in panel selection. The panel's documents list TUV Nord test reports for salt mist, dust-sand, ammonia and PID; in coastal projects, these reports are worth considering. The Solar Nexo team provides supply, design, installation, commissioning and after-sales technical support; the datasheet can be downloaded from this page. Theoretically, according to PVGIS data, 1 kWp produces about 1,656 kWh/year in Antalya; for a single 440 Wp panel, this comes to about 729 kWh/year (excluding shading, tilt and system losses).
