How Many Kilowatt Hours Does The Average Solar Panel Generate

Typically homeowners in the united states use about 900 kwh a month on average.

How many kilowatt hours does the average solar panel generate.

5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. Assuming a 30 day month an electricity generation of 1 000 kwh is equivalent to 33 33 kwh per day. 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.

Again though these are just rough estimates. However keep in mind that there are many factors at play here so this is really only a rough estimate. Once you know the peak sun hours estimating the number of solar panels needed for 1 000 kwh is simple. 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.

The us ranges from about 4 hours 6 hours of sunlight per day on average see the below map. You must simply divide the average daily kwh by the peak sun hours. How much energy does a solar panel produce. The first step is calculating the kilowatts needed.

So take 900 kwh and divide by the amount of kwh one solar panel produces over the course of a month 30kwh and you get a 30 panel installation. 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. An average residential solar panel size today is about five and a half feet by three feet. On average a normal household will use around 37 kwh per day.
