Solar Panel Yearly Production Per Square Foot

Said differently the average american household consumes just under 11 000 kwh per year.

Solar panel yearly production per square foot.

How many solar panels are needed to power an average house. Solar panels lose wattage as temperature increases and this is represented as a percentage loss per degree celsius. In order to find a range for number of solar panels we compared arizona and maine s solar panel production ratios 1 31 and 1 61 the highest and lowest in the u s. To understand how much solar power is produced per square foot it s helpful to know what solar panels are made of.

The us census bureau determined that single family homes have an average area of 2467 square feet. The average cost to install solar panels is from 10 626 to 26 460 after tax credit for a 6kw to 12kw system to power an entire house. Assuming 0 35 kwh for a 2 000 sq. Thin film panels produce the least energy per square foot.

1 our maxeon solar cell technology combines a strong copper backing with ultra pure silicon and a light trapping glass surface that ultimately makes our panels 30. That translates to just over 15 watts per square foot. For instance if you have a panel that puts out 265 watts and is 65 4 by 39 inches in size the energy produced per square foot would be around 15 watts. But every home is unique and could use more or less power than the average home.

All solar panels are rated by the amount of dc direct current power they produce under standard test conditions. When dividing these values you obtain 0 35 kwh per square foot. Energy information administration in 2018 the average monthly electricity consumption for a home in the united states was 914 kwh per month or about 30 5 kwh per day and 11 000 kwh per year. While this does not sound like very much square feet do add up pretty quickly.

Most solar panels last for 50 years have a 25 year warranty and start generating a return on investment after 8. Home the estimated electricity consumption is 700 kwh. According to the u s. Assuming the same size monocrystalline panels have the highest energy production followed closely by polycrystalline panels.

Sizing a solar panel system to your home s electric usage can be done by taking look at your energy bills over a year. Solar panel output is expressed in units of watts w and represents the panel s theoretical power production under ideal. Sunpower solar panels are the most efficient you can buy. Thus the output for each solar panel in your array would produce around 500 550 kwh of energy per year.

The average solar panel payback period is 7 to 12 years and solar energy saves 600 to 2 000 per year on electricity costs. How many solar panels do i need for 1 000 kwh per month. You can use the table of solar power production per kw for each state above to do the same math for your state. Simply put once you know how much power each panel puts out simply divide it by the square feet of the panel.
