Factory produced wire solutions improve consistency and quality, reduce field labor and waste, resulting in a lower total installed cost for your project.

ConnectPV produces a wide variety of wire harness and string wire solutions for the Solar PV industry. From standard wire harness components (X’s, T’s, Y’s) to custom wire harnesses, string wires, direct burial cable, and combiner whips – we provide an end to end source circuit wiring solution.

We provide solutions compatible with Fixed Racking or Tracker based arrays for thin-film and mono/poly crystalline modules. Harnesses can be modular, with connectorized sections, or can be continuous assemblies.

Our Engineers work with your site plans to determine lengths and overall system design. Drawings are produced for customer review and approval prior to production.
