As explained above the number of panels needed to reach 1 000 kwh per month changes depending on local sunshine and panel wattage.
Solar panels providing 11 kwh per day.
Many solar power company websites provide calculators for the average annual solar panel output per day in kwh for areas across the united states.
5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.
On average a normal household will use around 37 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.
Thus the output for each solar panel in your array would.
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.
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.
Solar panel output per day and per month.
Multiply by 30 days and you ll get mothly kwh output for the panel.
Combining all of the sunshine that falls on the solar panel over a 24 hour period the average roof in the united states gets about four hours of full or usable sun a day.
However keep in mind that there are many factors at play here so this is really only a rough estimate.
However solar power is an effective solution to reduce energy expenses.
How much energy does a solar panel produce.
