What's the highest-wattage solar panel you can buy in 2026?
As of Q1 2026, the highest-wattage commercial modules reach 850W on 210mm (G12) wafers with n-type TOPCon or HJT cells, and 810-830W HJT bifacial variants. JUST produces 680-740W HJT and 620-640W TOPCon in this class β OEM options available up to 850W.
Are high-wattage panels more efficient?
Not necessarily. Higher wattage often comes from larger physical size (210mm wafers), not higher cell efficiency. TOPCon cells typically hit 23-25% efficiency regardless of module wattage.
When should I use 700W+ panels vs standard 580W?
High-wattage (700W+) panels are ideal for utility-scale projects where BOS cost savings (fewer panels, less racking, simpler wiring) outweigh the logistics complexity. For rooftop or small C&I, 580-640W usually optimizes $/W.
