Solar Panel Interconnection Cables

Polar Wire's Solar Panel Interconnection Cables are premade to save time, labor, and tool costs.Polar Wire builds Solar Panel Interconnection Cables in a variety of lengths and configurations using SMK, MC4, and Tyco Connector Systems for photovoltaics. Our cables allow time-saving and safe serial and parallel wiring of PV modules for code-compliant building of integrated and free-standing solar installations.

Our Solar Panel Interconnection Cables are made in 15', 25', 30', 50', and 100' lengths, and 5' MC4 and TYCO connector cables are also stocked. 10 AWG solar panel cable is available by the foot.

Custom lengths available on request. SMK Connectors, splitters for Tyco to MC4, and custom adaptors available in our online store.

Arctic Ultraflex Blue 10 to 18 AWG single conductor wire is electro-tinned for superior conductivity and corrosion resistance.
