Average Kwh Solar Panel

However keep in mind that there are many factors at play here so this is really only a rough estimate.

Average kwh solar panel.

That s enough energy to power some small appliances without too much issue but if you want to cover the energy used by your property s climate control systems or large cooking appliances you ll need more solar panels. In order to find a range for number of solar panels we compared arizona and maine s solar panel production ratios 1 31 and 1 61 the highest and lowest in the u s. Typically homeowners in the united states use about 900 kwh a month on average. In the example above the solar panel is producing 1 5 kwh per day which ends up being about 45 kwh per month.

The amount of energy your home uses over a certain timeframe say a month is measured in kilowatt hours kwh. On average a normal household will use around 37 kwh per day. A typical american home will need 14 36 solar panels to cover their power bill and at least 227 square feet of rooftop space to accommodate the solar panels. Said differently the average american household consumes just under 11 000 kwh per 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. 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. Again though these are just rough estimates. 30 panels x 250 watts per panel equals a 7 500 watt system 7 5kw.
