Although cable management is one of the most important aspects of a photovoltaic (PV) system, it’s also commonly overlooked during installation. Cables must be properly routed, organized, supported, and protected so that they can endure the often harsh environments in which solar power systems are used.

There are many potential issues that could arise when wires and cables aren’t secured. These components are subject to extreme temperatures and often direct sunlight, wind, snow and rain. Sharp panel and mounting system edges can score cables, and rough roof shingles can abrade insulation with continual rubbing. Rodents and other animals enjoy living under the shade of solar panels and munching on dangling wires. Such damage not only jeopardizes the system’s reliability, but also its safety.

Solar panels and PV systems have a typical life expectancy of 20-30+ years. When all wires are properly managed, the system is much more likely to last and will require fewer repairs over the course of its lifetime. For the inevitable maintenance needed over time, however, proper cable management allows maintenance personnel to more easily troubleshoot and target problems.

Stainless steel solar cable clips of sunkean are available in many forms to meet a variety of needs. These clips are designed to fasten to module frames or mounting rails. They can clamp single or multiple PV cable(s). Some manufacturers provide 90° clips when the clipped surface length is perpendicular to the cable route.
