Is 5kw 5000 watts so you can use that as a benchmark if you re unclear on what your power needs will be.
Considering 6 peak sun hours per day and 300 watt panels you need 16 to produce 700 kwh each month.
But at 20 watts per square foot a system rated to produce 2 kilowatts would cover roughly 150 square feet while a 3kw system would take up about 225 square feet.
The average sized solar panel takes up an area of 17 6 square feet and produces 265 watts under direct sunlight.
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.
Energy information administration in 2018 the average monthly electricity consumption for a home in the united states was 914 kwh per month or about 30 5 kwh per day and 11 000 kwh per year.

The first is to look at the peak possible instantaneous solar power production per square foot for a particular solar panel.
This will maximize the watts installed per square foot compensating the area limitation.
But every home is unique and could use more or less power than the average home.
