PV Cable (a.k.a Solar Photovoltaic Cable) is a single-conductor cable used to connect the panels of a photovoltaic electric energy system. PV systems, or solar panels, are electric-power production systems that capture sunlight in order to produce electricity through an energy conversion process. Electricity is produced at the panel and wiring is needed to convey the electrical energy back to a collection point or piece of equipment. Photovoltaic cable is a specific kind of wire created for PV applications.
