The Importance of PV Array Wire Management
SECURING, SUPPORTING AND PROTECTING CONDUCTORS WITHIN THE PV ARRAY
PV systems are expected to have a 25-year lifespan, and array wire management solutions should match this expectancy. However, designers and installers face persistent challenges to managing free-air conductors within the PV array.
Implementing a safe, reliable and Code-compliant wire management system for exposed PV conductors is not an easy task. PV module leads can be too long or sometimes too short, requiring site-specific solutions for supporting and interconnecting the cables. Equipment grounding, PV source-circuit and inverter-output conductors from microinverters and ac modules must also be managed to ensure protection from potential damage. Within the PV array, these various conductors are often secured to module frames, support rails and other racking system components. While securing array wiring seems like it should be a straightforward exercise, the reality is that integrators continue to face numerous challenges.
