Cost of solar panels per square foot.
1 square foot solar panel.
To produce the maximum amount of power per square foot a solar panel has to be well designed to handle temperature spectrum angle and amount of light.
The average size of solar panels used in a rooftop solar installation is approximately 65 inches by 39 inches or 5 4 feet by 3 25 feet.
Thus the output for each solar panel in your array would.
There is some variation from brand to brand and if you re installing a large scale solar panel system such as for a warehouse or a municipal building your panels will be closer to 6 feet long.
The first is to look at the peak possible instantaneous solar power production per square foot for a particular solar panel.
That translates to just over 15 watts per square foot.
However most installers estimate solar costs by the amount of energy needed at 2 53 to 3 15 per watt before any tax credits or incentives.
The average sized solar panel takes up an area of 17 6 square feet and produces 265 watts under direct sunlight.

For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way.
