There are plenty of solar calculators and the brand of solar system you choose probably offers one. 1 kilowatt 1000 watt. Solar panel systems are measured in terms of kw. So take 900 kwh and divide by the amount of kwh one solar panel produces over the course of a month 30kwh and you get a 30 panel installation.

30 panels x 250 watts per panel equals a 7 500 watt system 7 5kw. Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark. How much electricity does one solar panel produce. 10 972 kilowatt hours per year the national average utility rate inflation.

You can use the table of solar power production per kw for each state above to do the same math for your state. It basically shows the rate at which power is consumed by a device. 94 energysage marketplace average electricity rate.
