A solar cable is the interconnection cable used in photovoltaic power generation. Solar cables interconnect solar panels and other electrical components of a photovoltaic system. Solar cables are designed to be UV resistant and weather resistant. They can be used within a large temperature range and are generally laid outside.
The cable's insulation must be able to withstand thermal and mechanical loads. As a consequence, plastics which have been cross-linked are increasingly used today. The insulation and jacket materials are extremely resistant to weathering, UV-radiation and abrasion . Additionally, it is salt water resistant and resistant to acids and alkaline solutions. It is suitable for fixed installation as well as for moving applications without tensile load. It is especially designed for outdoor use, which means direct sun radiation and air humidity, but due to the halogen free flame retardant cross-linked jacket material the cable can also be installed in dry and humid conditions indoors.
