You must simply divide the average daily kwh by the peak sun hours assuming a 30 day month an electricity generation of 1 000 kwh is equivalent to 33 33 kwh per day. For example if your solar panel is rated at 100 watts figure on about 30 watts output. The first step is calculating the kilowatts needed. The number of solar panels of the size used in the calculation will theoretically meet that energy demand during a sunny day.

That gives you 6 62 kw and some change. 12 month usage map area number 0 85 system size.
