On average, a solar panel can output about 400 watts of power under direct sunlight, and produce about 2 kilowatt-hours (kWh) of energy per day. Most homes install around 18 solar panels, producing an average of 36 kWh of solar energy daily. That’s enough to cover most, if not all, of a typical home’s energy consumption.
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.
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.
The output of solar panels is electrical energy in the form of direct current (DC) that is produced by your PV modules. Solar panel output is often expressed in watts (W) or kilowatts (kW), and the price you pay for your solar system is typically determined by its power output.
