The first step is to determine the average daily solar PV production in kilowatt-hours. This amount is found by taking the owner's annual energy usage and dividing the value by 365 to arrive at an average daily use. This will tell us how much energy we will need on a daily basis. For example, a residence has an annual energy usage of 6,000 kWh.
