What roof size do I need for solar panels? A typical 5kW residential system requires approximately 25-30 square meters (270-320 square feet). Formula: Panels = (Roof Area × Usable % × (1 − Spacing Loss %)) ÷ Panel Area → Total Capacity (kW) = Panels × Panel Wattage ÷ 1000. Determining how many solar panels fit on. . Here's what's shocking: A single square meter of solar panel can generate anywhere from 150 to 250 watts under ideal conditions. But "ideal" rarely exists in real life. Your roof's orientation, local climate, shading, and even the dust on your panels can slash that output by 30-50%. It calculates the maximum number of panels that fit on the available roof surface, taking into account important factors such as orientation, inclination. .
