How many kW is a house?
A small home in a temperate climate might use something like 200 kWh per month, and a larger home in the south where air conditioners account for the largest portion of home energy usage might use 2,000 kWh or more.

How many solar panels do I need for 1000 kWh per month?
One solar panel on your roof will produce an average of 1,350 watts or 1.35 kWh per day. 1.35 X 30 = 40.5 kWh per month (assuming a 30-day month). You need a solar panel system that produces 1,000 kWh per month. 1000 kWh / 40.5 kWh = 24.69 solar panels.
