Solar PV Modules

A PV Array consists of a number of individual PV modules or panels that have been wired together in a series and/or parallel to deliver the voltage and amperage a particular system requires. An array can be as small as a single pair of modules, or large enough to cover acres. 12 volt module is the industry standard for battery charging.

In front of PV panel arrays, the airflow had no noticeable effect from PV panel arrays, as shown in Fig. 5 c. On the leeward side of PV panel arrays, the airflow field can be divided into quiet zone, mixing zone, and restoration zone (Meyers, 2015). The airflow was still affected by PV panel arrays in the quiet zone, as shown in Fig. 11 e.
