The Solar connector is a single contact electrical connector. They are often used to connect solar panels, is an acronym for “Multi-Contact, 4mm”. This is the norm in the renewable energy industry. Solar connectors make it easy to build PV panel arrays. In today’s solar market,  connectors and their corresponding products are fully utilized. Most of the time, large solar panels are already equipped with connectors, made by Multi-Contact, the official manufacturer of Solar connectors. A solar panel is a plastic base circular housing with a single conductor in a male/female pair. With a notched interlock, Solar connectors can be terminated with each other to prevent them from being unintentionally pulled apart.
