Solar panel power output can get confusing fast. Is 400 watts good? 420 watts? Should you opt for the 450-watt panel? Is it worth the extra cost? About 97% of home solar panels installed in 2025 produce between 400 and 460 watts, based on thousands of quotes from the EnergySage Marketplace.
For example, 60-cell solar panels measure 99 x 167.6 cm and produce 270 to 300 watts, while 72-cell solar panels have an average output ranging between 350 and 400 watts due to the extra row of cells. Half cut cell panels appeared and these half-cell panels have been cut in half.
When considering solar panel sizes and wattage, you’ll typically find options ranging from 250 to 400 watts. Opting for higher wattage units can be a game-changer, especially for those with limited roof space.
The quantity of DC (direct current) power each solar panel can generate under typical test conditions determines its rating, including the wattage of solar panels. The power generated by a solar panel is measured in watts (W), which correspond to the panel’s optimum sunshine and temperature conditions.
