Next, PVMars will give examples one by one, please follow us! The theoretical output energy (E) of a solar power station can be calculated by the following formula: E=Pr×H×PRE =Pr×H×PR E: Output energy (kWh) Pr: Rated power of the solar energy system (kW), that is, the total power of all photovoltaic modules under standard test conditions (STC)
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.
