The primary purpose of conductors in a photovoltaic (PV) system is to carry electrical current. Conductors are essential components in any electrical system, including PV systems, as they provide a pathway for the flow of electricity generated by solar panels. When sunlight strikes the solar modules, they convert that energy into direct current (DC) electricity, which needs to be safely transmitted through conductors to inverters, batteries, or other components where it can be used or stored.

The importance of conductors cannot be understated; they must be appropriately rated for the specific current and voltage levels of the PV system to ensure safe and efficient operation. Conductors also need to be designed to minimize resistive losses during transmission, which can affect the overall efficiency of the energy conversion process.

Understanding the role of conductors as the means of transporting electrical energy is crucial for effectively designing, installing, and maintaining PV systems.
