How many solar panels do i need to power my house. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average. Not all solar panels are the same. The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size.

Those solar panels used for residential purposes range from 150 watts to 370 watts per panel depending on the panel size efficiency and cell technology.
