A 400 W solar panel can produce around 1.2-3 kWh or 1,200-3,000 Wh of direct current (DC). The power produced by solar panels can vary depending on the size and number of your panels, their efficiency, and the climate in your area. How many solar panels are needed to run a house? On average, 15-20 solar panels of 400 W are needed to power a house.
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.
PV wattage refers to the overall power output that a solar panel can provide in a specific amount of time. It is determined by factors such as voltage, amperage, and number of cells.
Divide the average daily wattage usage by the average sunlight hours to measure solar panel wattage. Panel output efficiency, energy usage, sunshine exposure, system capacity, panel types, and materials all impact the calculation.
