Rooftop Solar Panels
Official Product Series: CW Enerji 450–420Wp M10 108TNB G2G TOPCon Solar Panels
Technical Code: 108TNB10
The 108TNB10 family combines M10-format N-type TOPCon cells with a 108-cell, 6 × 18 half-cut arrangement. Its seven official model codes cover 420–450 Wp, with efficiency progressing from 21.51% to 23.04%.
A 1722 × 1134 × 30 mm footprint and 25.0 kg module weight make the series relevant to distributed and rooftop applications where module handling, roof segmentation and usable surface area influence the final layout. Its bifacial double-glass construction uses 2.0 mm front and rear glass and carries a published bifaciality rate of 80% ±5.
Rear-side contribution on a rooftop depends strongly on mounting clearance and the optical properties of the surface below the module. The family can provide meaningful project flexibility, but string voltage, MPPT current, structural loading, ventilation and fire-resistant roof construction must be reviewed as an integrated design.

Engineering / Selection Notes
- Complete a roof survey covering structural capacity, membrane condition, wind zones, drainage, access and fire-resistant construction before final module placement.
- Use the selected model’s Voc and the −0.260%/°C coefficient for cold-temperature string calculations.
- Bifacial modelling should be conservative for close-mounted roofs. Elevated mounting, light-coloured surfaces and limited rear obstruction are more favourable.
