Design Principles of Photovoltaic Irrigation Systems
The group of PV cells is known as the PV module. PV panels consist of an array of solar cells connected to form a circuit "in series" to increase the output voltage up to the desired value. The main function of the PV array is to produce a DC between its two terminals when they are illuminated by sunlight (Fig. 9.3).
