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:
About 97% of solar panels quoted on the EnergySage Marketplace in 2025 are 400 to 460 watts—expect to see panel outputs in this range in your quotes. Your panels' actual output will depend on your roof's shading, orientation, and hours of sun exposure. The efficiency and size of your solar panels drive their power output.
A solar panel wattage calculator can help optimize your solar power system for maximum efficiency and cost-effectiveness. This calculator considers variables such as panel efficiency, sunlight intensity, and environmental conditions, allowing for a more accurate prediction of the electricity a solar panel can generate.
The daily energy production of a 100-watt solar panel is influenced by the amount of sunlight it receives. On average, you can expect: Assuming 5 peak sun hours: 100W × 5 hours = 500 watt-hours (0.5 kWh) per day. In optimal conditions: The panel may produce up to 600-700 watt-hours (0.6-0.7 kWh) daily.
