Average Kwh Solar Panel

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.

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. On average a normal household will use around 37 kwh per day. 30 panels x 250 watts per panel equals a 7 500 watt system 7 5kw. The amount of energy your home uses over a certain timeframe say a month is measured in kilowatt hours kwh.

Said differently the average american household consumes just under 11 000 kwh per year. Again though these are just rough estimates. 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. 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.

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. However keep in mind that there are many factors at play here so this is really only a rough estimate. In the example above the solar panel is producing 1 5 kwh per day which ends up being about 45 kwh per month. 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.
