If you take 1 5kwh as the average then you will require at least 47 panels.
How much electricity do solar panels produce per hour.
The electrical energy that is generated by a solar panel or a solar system can be expressed as watts or kilowatts.
The next step is to know how much electricity an average solar panel produces.
How much solar power do i need solar panel kwh.
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.
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.
Given 1kw of panels produces 1642 kwh per year in ca and 1kw of panels takes up 68 42 square feet solar panels installed in california on average produce 23 99 kwh kilowatt hours per square foot per year.
So the kwh divided by the hours of sun equals the kw needed.
5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.
One kilowatt hour equates to 3 6 megajoules.
The calculations would be like this.
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.
25 000 kwh 365 1 5kwh per day 47 panels.
Kwh a measure of electrical energy that is equal to the consumption of 1000 watts for 1 hour.
On average a normal household will use around 37 kwh per day.
Or 30 kwh 5 hours of sun 6 kw of ac output needed to cover 100 of your energy usage.
