Let''s say you get 26 450-watt solar panels installed on your roof: That gives you a 11,700 watt, or 11.7 kW solar panel system (near the average system size quoted on the EnergySage Marketplace).
A 6.7 kW solar system produces 30.15 kWh of electricity per day. And to build a 6.7 kW solar system, you need 14 500-watt solar panels. If you have a smaller household, you could cover your energy use with a less expensive 4 kW solar system that produces 18 kWh of electrical energy per day, and you can build it with just 8 500W solar panels.
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.
