Q: Are solar photovoltaic cables waterproof? Can they be directly buried or used exposed on rooftops?
A: Yongshang solar photovoltaic cables offer excellent weather and water resistance with IP67 protection (when used with MC4 connectors), suitable for:
• Exposed rooftop installation: fully UV, temperature and rain resistant — the most common application;
• Conduit burial: recommended to run through PVC/galvanized conduit for protection against mechanical damage and rodents;
• Coastal/humid areas: tinned copper conductor + XLPO sheath resist salt spray corrosion;
• Desert/cold regions: remains flexible down to -40°C without cracking.
Important notes:
1. Avoid friction against sharp metal roof edges — use weather-resistant clips, do not over-tighten cable ties;
2. Use red (+) and black (-) for DC polarity to ease maintenance;
3. Certified MC4 connectors are recommended for waterproof and reliable connections.
