The Sunroko 730W solar panel; Key Features and Specifications High Output & Efficiency: Produces 730 watts of direct current (DC) electricity with an efficiency rating exceeding 23%. N-Type Cell Technology: Uses advanced N-Type cells with TOPCon or HJT (Heterojunction Technology). This makes the panel last longer, degrade slower, and perform better in hot weather compared to older, standard panels.Bifacial Design: The panel is bifacial, meaning it can absorb sunlight on both the front and the back sides. When mounted on a reflective surface the back side can generate an extra 10% to 25% of power
