Solar Panel Kilowatt Hour Calculator

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.

Solar panel kilowatt hour calculator.

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. 1 000 watts x 10 hours per day 10 kwh per day check out our off grid load evaluation calculator. Calculators that use kilowatt hours are more accurate because they consider your exact energy needs those that ask for home area must assume the electricity consumption. The tool works by taking your average monthly energy usage in kilowatt hours kwh.

I have a 17 panel system each panel at 305w in las vegas and the calculation is right on the money. If you re using 1400 kwh per month let s consider an average of 6 hours of sunlight per day this implies you would need 1400 6 30 7 7 kw at least every hour i e. 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. An 8 10 kw system.

Calculate solar system capacity. 8 76 kw grid tied solar system with solaredge and 24 astronergy solar 365 watt panels wss solaredge gridtie system for 24 astronergy 72 cell modules 12 406 00. The first thing to do is to find out how many units of electricity you are consuming on an average monthly. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.

Determine how many solar panels you ll need one solar panel produces about 1 24 kwh per day. After estimating daily usage we need to consider which type of battery will work best as they have unique performance characteristics and are sized differently. Our solar calculatorcan estimate the number of panels needed for your home. 2000 x 5 185 kw 10 370 kwh x 0 78 8089 kwh year x 0 12 kw 970 savings 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. You can use the table of solar power production per kw for each state above to do the same math for your state. For instance if the surface area is 1 500 square meters and the rating of the panel is 250 watts you would divide 250 by 1 500 and then multiply by 100 to find the percentage.
