Amount of solar panels needed to power a house. Map courtesy of google maps. The panels you would use in a residential setting typically range from 275 to 350 watts per panel. If you multiply that by 30 you get 38 4 kwh per month and that s just one solar panel. A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels.

Assuming a homeowner used the national average of 911 kwh per month they would need about 24 solar panels to supply their house with electricity.
