Solar Roof Kwh Per Day

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

Solar roof kwh per day.

On average a normal household will use around 37 kwh per day. Let s say on a good day you average 5 hours of direct sunlight. Let s estimate you get about five hours per day to generate that 30 kwh you use. The us ranges from about 4 hours 6 hours of sunlight per day on average see the below map.

So the kwh divided by the hours of sun equals the kw needed. 4 how does that compare to your annual energy usage. 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. Because of the variables pinning down exact numbers is tough.

Or 30 kwh 5 hours of sun 6 kw of ac output needed to cover 100 of your energy usage. So how many square feet of your roof will your pv solar system cover. If you have 33 panels assuming a 30 day month you will get 1 000 kwh per month. Assuming a 30 day month an electricity generation of 1 000 kwh is equivalent to 33 33 kwh per day if the site gets 6 peak sun hours per day you need 5 56 kilowatts since no energy conversion system is perfect you cannot assume the solar array will deliver its theoretical production.

But at 20 watts per square foot a system rated to produce 2 kilowatts would cover roughly 150 square feet while a 3kw system would take up about 225 square feet. If you have four panels you will get 4 kwh per day.
