How Much Electricity Do Solar Panels Produce Per Square Foot

An array of this size can produce an average of 350 850 kwh of ac energy per month.

How much electricity do solar panels produce per square foot.

For a 300 watt solar panel with dimensions 64 inches x 39 inches 1 61 meters squared or 17 31 square feet the peak instantaneous electricity production per square foot at stc is 14 58 watts per square foot. Assuming the same size monocrystalline panels have the highest energy production followed closely by polycrystalline panels. That translates to just over 15 watts per square foot. This is typical for residential solar panels being sold in the us in 2020.

Solar panels lose wattage as temperature increases and this is represented as a percentage loss per degree celsius. 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. How much energy does a solar panel produce per square foot. To put that into perspective a typical household uses about 897 kwh per month.

Thin film panels produce the least energy per square foot. Because of the variables pinning down exact numbers is tough. A common size solar panel array is usually around 5kw and takes up around 400 square feet of space. The average sized solar panel takes up an area of 17 6 square feet and produces 265 watts under direct sunlight.
