How much electricity does a solar panel produce per year. In a high yield solar area like central colorado which receives annual insolation of 2000 kwh m 2 year such a panel can be expected to produce 400 kwh of energy per year. December produces only 122 kwh which is just 17 as much as july. Smart design decisions can also improve the productivity of a solar power system. A common size solar panel array is usually around 5kw and takes up around 400 square feet of space.

Given 1kw of panels produces 1642 kwh per year in ca and 1kw of panels takes up 68 42 square feet solar panels installed in california on average produce 23 99 kwh kilowatt hours per square foot per year. To put that into perspective a typical household uses about 897 kwh per month. Thus the output for each solar panel in your array would produce around 500 550 kwh of energy per year. Simply put once you know how much power each panel puts out simply divide it by the square feet of the panel.

All solar panels are rated by the amount of dc direct current power they produce under standard test conditions. For oregon and washington it is slightly lower. As you can see the summer is when my system generates the most electricity with an average total generation of 717 kilowatt hours in the month of july. March is a lot better at 430 kwh but still only 60 of july s average.

10 812 kwh per year washington. The exact electricity production depends on the panel specifications and the amount of sunshine received. So if you have a 7 5 kw dc system working an average of 5 hours per day 365 days a year it ll result in 10 950 kwh in a year. 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.

11484 kwh per year as a reference point a kilowatt hour is equal to 1 000 watts of power being used for one hour. Each solar panel can be expected to produce between 400 and 600 kilowatt hours per year. To figure out how many kilowatt hours kwh your solar panel system puts out per year you need to multiply the size of your system in kw dc times the 8 derate factor times the number of hours of sun.
