A solar panel produces between 1.1 and 2.5 kilowatt-hours of power in one day, which amounts to 33 to 75 kWh per month. As an average home in the US uses about 900 kWh, you will need between 27 and 12 solar panels to cover that usage, depending on the panel efficiency and how many watts each solar panel produce.
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.
A 300-watt solar panel will produce anywhere from 0.90 to 1.35 kWh per day (at 4-6 peak sun hours locations). 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).
A 6.7 kW solar system produces 30.15 kWh of electricity per day. And to build a 6.7 kW solar system, you need 14 500-watt solar panels. If you have a smaller household, you could cover your energy use with a less expensive 4 kW solar system that produces 18 kWh of electrical energy per day, and you can build it with just 8 500W solar panels.
