Solar panel wattage is the maximum amount of power a solar panel can produce under ideal conditions. It’s measured in watts (W) and represents the panel’s peak power output. For example, a 400-watt solar panel can generate up to 400 watts of electricity when exposed to full sunlight in a controlled test environment.
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.
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.
Based on our energy output estimates for a location with five sunlight hours, a 500-watt solar panel would produce approximately 2.5 kWh: 500 watts x 5 hours = 2,500 watts OR approximately 2.5 kWh per day. How can you increase solar panel efficiency?
