Solar panel kilowatt hour calculator.

An 8 10 kw system. The fed tax rebate was 30 on the total install cost and nv energy rebated 1100. The first thing to do is to find out how many units of electricity you are consuming on an average monthly. 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.

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. 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. 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. You need to divide the number of watts at which the panel is rated by the total surface area of the panel.

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. 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. 1 000 watts x 10 hours per day 10 kwh per day check out our off grid load evaluation calculator. Determine how many solar panels you ll need one solar panel produces about 1 24 kwh per day.

Our solar calculatorcan estimate the number of panels needed for your home. 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. The tool works by taking your average monthly energy usage in kilowatt hours kwh. Calculate solar system capacity.

5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel. 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.
