How much roof space do solar panels need?
On average, the amount of required roof space for a set of home solar panels is between 300 sq ft and 500 sq ft total. When looking into a system for your home, the amount of required roof space will be dictated by the number of solar panels you plan to install. However, limited roof space can also limit the potential size of your installation.
How much space do solar panels take up?
The average residential solar panel size is about 17.5 sq ft—though it's good to overestimate the area required as some installation space is necessary between the panels and rows. When installing 22 panels like in our example, and each panel takes up about 18 sq ft, your system would require approximately 396 sq ft of roof space.
What is a solar panel calculator?
Our solar panel calculator helps you determine how many solar panels can be installed on your roof and how much electricity they can generate. It calculates the maximum number of panels that fit on the available roof surface, taking into account important factors such as orientation, inclination, and panel type.
