How Many Kilowatt Hours Does The Average Solar Panel Generate

Let s estimate you get about five hours per day to generate that 30 kwh you use.

How many kilowatt hours does the average solar panel generate. The us ranges from about 4 hours 6 hours of sunlight per day on average see the below map. However keep in mind that there are many factors at play here so this is really only a rough estimate. Typically homeowners in the united states use about 900 kwh a month on average. Remember if you are receiving an average of four hours of usable sunshine per day and your solar panel is rated at 250 watts of power then you will need forty panels to reliably generate 1 000 kwh per month.

Once you know the peak sun hours estimating the number of solar panels needed for 1 000 kwh is simple. Or 30 kwh 5 hours of sun 6 kw of ac output needed to cover 100 of your energy usage. You must simply divide the average daily kwh by the peak sun hours. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.

Again though these are just rough estimates. 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. On average a normal household will use around 37 kwh per day. How much energy does a solar panel produce.

The first step is calculating the kilowatts needed. So the kwh divided by the hours of sun equals the kw needed. An average residential solar panel size today is about five and a half feet by three feet. So if you have solar panels that each produce 1 kwh of power per day you would need a full 37 solar panels to fully power your home.
