*5.2. PV Support Structure*

The project involves the installation of specific support structures for the PV modules to allow an optimal exploitation of the available surface. The proposed structure is illustrated in Figure 13. It is a modular solution that simultaneously occupies two parking spaces and can also hold up to 9 PV panels at a time. The steel structure guarantees the best balance between lightness and strength of the structure. Evidently, the presence of the support rails, due to their shadowing, implies an inversely proportional impact on the power gain of the double-sided technology. For the present work, a gain in power of 5% will be cautiously considered.
