About 97% of home solar panels installed in 2025 produce between 400 and 460 watts, based on thousands of quotes from the EnergySage Marketplace. But wattage alone doesn''t tell the whole story. In fact, efficiency matters more than wattage when comparing solar panels—a higher wattage can simply mean that a panel is larger.
However, wattage alone doesn’t tell the full story—actual solar panel output depends on sun exposure, climate, and installation quality. Large rooftops and utility-scale projects use bigger, more powerful commercial solar panels ranging from 500 to 700 watts.
Divide the average daily wattage usage by the average sunlight hours to measure solar panel wattage. Panel output efficiency, energy usage, sunshine exposure, system capacity, panel types, and materials all impact the calculation.
About 97% of home solar panels included in EnergySage quotes today have power output ratings between 400 and 460 watts. The most frequently quoted panels are around 450 watts, so we''ll use this as an example.
