Solar conduit is protective tubing that houses and shields electrical wiring in photovoltaic systems from physical damage, UV exposure, and environmental degradation. Available in rigid metal, flexible metal, or PVC materials, solar conduit meets National Electrical Code (NEC) Article 690 requirements for outdoor solar installations. Proper conduit sizing, typically ranging from 0.5 to 1.5 inches in diameter, ensures adequate wire protection and maintains system safety throughout its 25+ year operational life.
Technical Specifications
Solar conduit must be UV-resistant and rated for outdoor exposure. Rigid metal conduit (RMC) offers superior protection in high-traffic areas, while flexible conduit works better around roof penetrations and equipment connections. Conduit fill calculations require that wires occupy no more than 40% of the internal cross-sectional area per NEC guidelines.
Installation Importance
Proper conduit installation prevents rodent damage, reduces voltage drop, and ensures compliance with local building codes. Conduit must be bonded to the system ground at specified intervals, typically every 10 feet, to provide electrical continuity and lightning protection for residential and commercial installations.
