108 half-cell N-type TOPCon: 450 W at high efficiency
At its core are 108 half-cut N-type TOPCon cells with a stated module efficiency of 22.5%. N-type technology eliminates the first-weeks degradation typical of P-type PERC: no more than 1% loss in year one, roughly 0.4% per year thereafter, with a 30-year performance warranty guaranteeing at least 83.1% of nameplate output. For a project with a long payback horizon, that is a direct economic advantage — output projections 20 to 30 years out become more reliable.
1500V maximum system voltage — lower cabling and BOS cost
Bifacial generation on light-colored roofs
Best fit: commercial, agricultural, and shelter roofs
The module suits warehouse roofs, production halls, livestock facility structures, and equipment or parking canopies well, where what matters is not only generation but also structural load per square meter — a higher wattage per unit area allows fewer mounting support points overall.
Black Frame design
A black frame and black backsheet give a visually uniform surface, which on commercial sites is often chosen to match corporate facade or roofing design rather than purely for residential aesthetics.
Engineers designing commercial-scale stations increasingly calculate not cost per watt but total lifetime cost per kilowatt-hour — and this is where high-wattage modules with a long glass-glass warranty outperform panels with a lower upfront price but a shorter real service life.
