The model will be used to derive the so-called solar cell equation, which is a widely used relation between the electric current density I leaving the solar cell and the voltage V across the converter. For this purpose, we use the relation for generated power P = I ⋅ V and Eq. (127) and we obtain: By using Eqs. (128), (129) we derive:
The higher the quantity of voltage, the more pressure there is to push the electrical current. The total amount of power produced by a solar module is measured in watts (W). Power (measured in Watts) is calculated by multiplying the voltage (V) of the module by the current (I).
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.
