About 97% of solar panels quoted on the EnergySage Marketplace in the second half of 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. . Estimate daily, monthly, and yearly solar energy output (kWh) based on panel wattage, quantity, sunlight hours, and efficiency factors. Losses come from inverter efficiency, wiring, temperature, and dirt. Increasing panel count or choosing higher wattage. . Most common solar panel sizes include 100-watt, 300-watt, and 400-watt solar panels, for example. The biggest the rated wattage of a solar panel, the more kWh per day it will produce. How Much Sun Do You Get (Peak Sun Hours). Input your solar panel system's total size and the peak sun hours specific to your location, this calculator simplifies. . Caution: Photovoltaic system performance predictions calculated by PVWatts ® include many inherent assumptions and uncertainties and do not reflect variations between PV technologies nor site-specific characteristics except as represented by PVWatts ® inputs. It starts off with the following equation: Where: electricity consumption (kWh/yr) – Total average amount of electricity you use annually. It's easy to use, requires just a few inputs, and provides accurate projections that can help you make informed decisions. .
