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.
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.
Usually, it is 1.2 to 1.5 which is multiplied by the desired output. For example with a 20% buffer, the required solar panel output with Buffer (Watts) = 6 kW×1.20 = 7.2 kW Nevertheless, when you are choosing solar panels make sure their power ratings equal or surpass the required output to meet your energy needs and preferences.
About 97% of solar panels quoted on the EnergySage Marketplace in 2025 are 400 to 460 watts—expect to see panel outputs in this range in your quotes. Your panels' actual output will depend on your roof's shading, orientation, and hours of sun exposure. The efficiency and size of your solar panels drive their power output.
