How Many Solar Panels Can I Fit on My Roof? – Solar Panel Sizes

Solar panels can differ in size depending on the brand and use purpose; the number of solar panels that will fit on your roof depends on which type of solar panels you decide to purchase. The average area of a residential solar panel is 17.62 square feet, but you can likely find smaller or larger options by consulting your local solar company

The size of solar panels is determined by their material, wattage requirement, and electricity output. If you need more output, you’ll need solar panels with a larger surface area.

How Many Solar Panels Can I Fit on My Roof? – Roof Size

A critical factor to consider is the size of your roof. Since the average solar panel has an area of 17.5 square feet, you can easily calculate the number of solar panels that will fit on your roof if you know their size. 

To get a broad estimate, divide the open roof space by 17.5 or the exact dimensions of the panels you plan to use if you have that information. Of course, there is more that goes into system design and solar panel selection than that, but this is a good way to get a basic understanding of how many panels your system may support. 

Note that you should divide the open roof space, not the total roof space, by 17.5 (or the size of your solar panels).

It is not practical for solar panels to cover every inch of your roof, and most solar panels are not designed to touch the roof’s edge. Your roof may be obstructed by materials, a chimney, or other extrusions. Thus, you won’t be able to place solar panels in these areas.
