Most solar panels you can find today are rated between 250 and 550 watts of power. The wattage (W) is what solar manufacturers and installers put first in the product description. To get the energy production of solar panels in a day, we need to multiply that number by the number of peak sun hours.
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?
A 400-watt solar panel will produce anywhere from 1.20 to 1.80 kWh per day (at 4-6 peak sun hours locations). The biggest 700-watt solar panel will produce anywhere from 2.10 to 3.15 kWh per day (at 4-6 peak sun hours locations). Let’s have a look at solar systems as well:
