Product Introduction

This bifacial module pairs N-type TOPCon cells with a symmetrical dual-glass laminate: 2.0mm heat-strengthened glass front and back, with no opaque backsheet. Sunlight reflected from the ground, roof membrane or snow reaches the rear cell surface and is converted as well, adding real energy on top of the front-side rating.

The bifaciality factor of 80% ± 5% means the rear side converts 80% as efficiently as the front. In practice, on a high-albedo surface such as white TPO membrane, light-coloured gravel or sand, total energy gain typically lands between 5% and 25% depending on mounting height, row spacing and ground reflectivity — with tracker-mounted arrays over bright ground at the top of that range.

Dual glass also changes the durability profile: glass does not hydrolyse the way polymer backsheets do, so the module is rated for a 30-year power warranty and carries a much lower long-term PID and moisture-ingress risk. This is the construction of choice for ground-mount, carport and elevated-tilt commercial roofs.

Main Features

Bifacial gain of 5–25% in real installations, driven by ground albedo, mounting height and row pitch — extra kWh at no extra module count.
Symmetrical dual-glass laminate is fire-resistant, water-vapour tight and free from backsheet cracking or yellowing.
N-Type TOPCon substrate: no LID, negligible PID, first-year degradation only 1% and 0.4% per year thereafter.
Temperature coefficient of −0.30 %/°C keeps output high on hot afternoons when yield matters most.
Rated for 5400 Pa front / 2400 Pa rear mechanical load and certified for salt-mist and ammonia environments.
30-year linear power warranty with ≥ 87.4% guaranteed output, and a 15-year product warranty.
