The size of solar panels varies, with no definite answer. Their wattages also differ as each system operates on different power levels. To learn more about solar panel sizes and wattage, keep reading.
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.
If two solar panels have 20% efficiency ratings, but one has a power output rating of 350 watts and the other is rated at 400 watts, all that means is that the 400-watt panel is about 14% larger than the 350-watt panel. You''ll get more power out of the 400-watt panel, but only because it takes up more space on your roof.
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.
