Energy information administration in 2018 the average monthly electricity consumption for a home in the united states was 914 kwh per month or about 30 5 kwh per day and 11 000 kwh per year. 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. Take these factors into account.

In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel.

Choose the right solar panels.
