The real test of a photovoltaic pv solar system is how well it works in real world conditions.
How much power do solar panels produce.
Solar panels usually produce between 250 and 400 watts of power.
To put that into perspective a typical household uses about 897 kwh per month.
A common size solar panel array is usually around 5kw and takes up around 400 square feet of space.
You can use the table of solar power production per kw for each state above to do the same math for your state.
Again these are just estimates since multiple factors will affect the production and usage of power.
To produce the maximum amount of power per square foot a solar panel has to be well designed to handle temperature spectrum angle and amount of light.
Therefore it is very possible to generate enough energy to cover 100 of your needs.
If a solar panel is rated to produce say 360 watts and it s about 3 and feet wide by 5 and feet long then each square foot must produce about 20 watts right.
You might think it s a simple math question.
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 power use translates to an average of 30 34kwh per day.
On average a normal household will use around 37 kwh per day.
You can freely compare solar quotes on the energysage marketplace to see how different wattage panels will affect your unique system.
An array of this size can produce an average of 350 850 kwh of ac energy per month.
With this estimate if for example you have solar panels that produce 1 5 kwh per day then you require around 22 solar panels to cover for all your power needs.
