Photovoltaic power generationis a power generation technology that uses photovoltaic panels to receive sunlight and convert solar energy into electrical energy. It is more environmentally friendly than thermal power generation, and has lower environmental requirements than hydropower generation. Grounding (also known as earthing) is the process of physically connecting the metallic and exposed parts of a device to the earth. It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. This article covers grounding. This article addresses the technical, aesthetic, and strategic problem of the limited attention paid to design and selection of materials in photovoltaic system (PSS) support structures despite their direct impact on the efficiency, durability and economic viability of these systems. They are loaded mainly by aerodynamic forces. International regulations as well as the competition between industries define that they must withstand the enormous loads. to fluctuating wind loads compared to the axial force.
