How Many Solar Panels Do I Need For My Home?

It’s a bit of a tricky question.

To start with, you need to know the average solar production of your local area. If you live in a sunny climate, like southern California or Arizona, then you’ll need fewer panels than someone who lives in Seattle or New York City.

But even within a single city there can be significant variation between neighborhoods. If you’re on the coast, where there’s more direct sunlight and less cloud cover, then that could mean more production for you than for someone who lives just down the street. And if you have trees around your house or on your roof, then those can shade your panels and reduce their output by up to 50%.

So it all depends! To get an accurate answer, I would recommend calling an installer near where you live and asking them how many panels they think you would need so that they could produce 300 kWh per month consistently throughout the year.
