Modern residential panels typically produce 300 to 400 watts each. Higher-wattage panels generate more electricity, reducing the number needed. Efficiency also matters—panels with higher efficiency (e.g., 20–22%) convert more sunlight into electricity, ideal for homes with limited roof space.
The number of solar watts you need will depend on the size of your home. To give you an idea, a 2,000 sq foot home uses an average of 32 kWh per day. For this type of household, a 5.8 kW solar system would be needed to generate enough energy to power the entire house. Solar panels are typically sized in kilowatts.
To answer how many solar panels to power a house for your specific situation, follow these steps: Sum your annual kWh from utility bills. Adjust for future needs (e.g., EV, home expansion). Use PVWatts or local solar data to find your area’s average peak sun hours. Select panels (e.g., 350–400 watts) based on budget and roof space.
A 100-watt solar panel produces 85 – 87 watts per hour energy on average in full sunlight and ideal conditions. However, a typical US residential utility customer uses on average 1224 watts per hour. Therefore, a 100-watt solar panel is not enough to power a home.
