Solar Roof Kwh Per Day

The us ranges from about 4 hours 6 hours of sunlight per day on average see the below map.

Solar roof kwh per day.

Let s estimate you get about five hours per day to generate that 30 kwh you use. However keep in mind that there are many factors at play here so this is really only a rough estimate. If you have one 250 watt panel receiving four hours of sun then you will get 1 000 watts or one kwh per day from that panel. So how many square feet of your roof will your pv solar system cover.

4 how does that compare to your annual energy usage. Or 30 kwh 5 hours of sun 6 kw of ac output needed to cover 100 of your energy usage. If you have four panels you will get 4 kwh per day. 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.

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. Because of the variables pinning down exact numbers is tough. 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.

So the kwh divided by the hours of sun equals the kw needed. Multiply 5 hours of sunlight x 290 watts from a solar panel 1 450 watts or roughly 1 5 kilowatt hours per day.
