Simply put once you know how much power each panel puts out simply divide it by the square feet of the panel.
Residential solar installation area kwh panel size.
The average system in the u s.
Solar panel insurance guide.
This works out to 15 sixty cell 275 285 watt solar panels or 12 seventy two cell 350 watt solar panels.
But if you used medium efficiency panels that number lowers to 508 sq ft.
Total area 1 0 18 5 56 m 2 i you are going to install all the panels in one line you would need a space of approximately 1 m x 5 56 m each panel having a size of 1 m x 0 556 m on your rooftop.
To match that energy requirement a 4 23kw system solar system is required.
In order to calculate the below data we averaged annual kwh production in the top 12 solar states and assumed standard 250 watt panels in order to calculate how many panels you would need.
Is 6 kilowatts kw.
A 2 000 square foot home in california may need 23 sixty cell panels or 18 larger seventy two cell solar panels to be energy efficient.
Is 5kw 5000 watts so you can use that as a benchmark if you re unclear on what your power needs will be.
And for highly efficient panels it reaches down to 448 sq ft.
The average system size in the u s.
To cover that energy need.
Because every house is different shading and roof slopes vary and because some families use more energy than others the number of solar panels your home needs is you.
If you install a 6 kilowatt kw system with 20 average sized panels your system will likely measure approximately 27 feet wide by 13 feet long 352 square feet in all.
