System size kw square footage needed for low efficiency 16 square footage needed for medium efficiency 18 square footage needed for high efficiency 22 5 kw.
So we have approximately 850 square feet of roof to mount solar panels.
If you used the solar nerd calculator you ll have an estimate of how many solar panels you need to generate all of your electricity but then the question is.

While your home is far from average this is how you can calculate your own rough estimate.
Divide 6 62 kw the system size by 320 kw the wattage per panel 20 69 rounded up that s 21 panels.
But at 20 watts per square foot a system rated to produce 2 kilowatts would cover roughly 150 square feet while a 3kw system would take up about 225 square feet.
Because of the variables pinning down exact numbers is tough.
