Calculate Solar Panel Output Per Day

Or 30 kwh 5 hours of sun 6 kw of ac output needed to cover 100 of your energy usage.

Calculate solar panel output per day.

At 18 7 efficiency that s 0 898 kwh m day. Louis mo is firmly in the 4 5 to 5 0 section of the map. Please have a look at your average annual consumption number in kwh which you wrote down from the previous page. 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.

Let s estimate you get about five hours per day to generate that 30 kwh you use. Solar panel watts x average hours of sunlight x 75 daily watt hours as an example let s say you have 250 watt solar panels and live in a place where you get 5 hours of sunlight per day. You must simply divide the average daily kwh by the peak sun hours assuming a 30 day month an electricity generation of 1 000 kwh is equivalent to 33 33 kwh per day if the site gets 6 peak sun hours per day you need 5 56 kilowatts. How to calculate solar panel output here s a simple formula for calculating your solar panel s power output.

Let s call it 4 75 kwh m day. So the kwh divided by the hours of sun equals the kw needed. The us ranges from about 4 hours 6 hours of sunlight per day on average see the below map. Solar power as a function of time in kwh or wh that your solar panel can produce taking into account its rated power and solar energy available at your place.

5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. Therefore to figure out how much power the panel produces in a day simply multiply the 250 watts by 4 hours which comes to 1000 watts per day. For example in the us the average amount of full usable sunlight per day is about 4 hours. At 1 63 m each solar panel can make around 1 45 kwh per day and 3 3 of them can make 4 79 kwh day pretty dang close to the 4 75 kwh again on average.
