Statistics showthat most people consume more electricity during the summer and winter, when the A/C or heat is running. If possible, collect your last 12 months of electric bills, then tally up your kWh usage and divide by 12 to get a monthly average.

Next, divide your monthly kWh usage by 30 to estimate your average daily kWh usage. The average American home uses about 900 kWh per month, so we’ll use that in our example: 900 kWh / 30 days = 30 kWh per day .

From there, we need to add a bit of overhead to account for inefficiencies and degradation rate of the panels. The output of solar panelsdrops slightly each year, which is outlined by.
