The calculations would be like this.
How much electricity do solar panels produce per hour.
So the kwh divided by the hours of sun equals the kw needed.
However keep in mind that there are many factors at play here so this is really only a rough estimate.
How much energy does a solar panel produce.
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.
Let s estimate you get about five hours per day to generate that 30 kwh you use.
Kwh a measure of electrical energy that is equal to the consumption of 1000 watts for 1 hour.
25 000 kwh 365 1 5kwh per day 47 panels.
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.
The kwh is used as a billing unit for the energy consumed by individuals.
5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh.
Or 30 kwh 5 hours of sun 6 kw of ac output needed to cover 100 of your energy usage.
On average a normal household will use around 37 kwh per day.
The next step is to know how much electricity an average solar panel produces.
For example the standard panels produce an average of 1 1 5 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.
One kilowatt hour equates to 3 6 megajoules.
