A 100-watt solar panel installed in a sunny location (5.79 peak sun hours per day) will produce 0.43 kWh per day. That’s not all that much, right? However, if you have a 5kW solar system (comprised of 50 100-watt solar panels), the whole system will produce 21.71 kWh/day at this location.
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 instance, a 100W panel may produce 60W-75W in direct sunlight on a typical day. This output decreases further when there’s cloud cover, dirt, or improper panel positioning. It’s crucial to understand that real-world performance differs from lab ratings.
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:
