12.2.2 PV plant design
The distribution of photovoltaic modules in the PV*SOL program is realized with the tab named Module Coverage ( Fig. 1 ). This option allows coverage of the installation area in two ways. The first is to manually fill individual modules, and the second is to automatically fill the entire available area.
.
The photovoltaic modules, like inverters, are chosen from a database built into the program, which is constantly updated by the producer. Thanks to it, it is possible to quickly select photovoltaic modules for which the most important parameters are given, such as: rated power, voltage, current and dimensions, as well as the type of PV cell used. An example of the component database is shown in Fig. 2.
.
An example of the design of a photovoltaic system installed on a south-facing pitched roof is shown in Fig. 3. The program allows you to edit the parameters of the modules such as the distance between the modules and the position relative to the roof. The example installation consists of 19 GH240P156 series photovoltaic panels from GH Solar with a total capacity of 4.56 kWp. In addition, the program allows you to automatically design the cabling for the photovoltaic installation Fig. 4. The program calculates the cross-sections of all the cables used, their lengths, as well as the cable losses of the entire installation.
