Devices made of photovoltaic cells that convert sunlight into direct current. The right choice depends on your project: — monocrystalline (n-type TOPCon) — maximum efficiency (22–23%), low degradation, suited for commercial and long-term projects; — bifacial, glass-glass — generate power from both sides, 30+ year lifespan, ideal for snowy conditions and light-coloured roofs.
