The solar energy market has grown exponentially in recent years. As a result, the installation of cables in photovoltaic panels has now become an important area. To reduce failures and maintenance, professional cable management is essential.
But what do workers need to look out for?
Which products are the most suitable?
It pays off to train employees right from the start and make them aware of the most important aspects when installing solar cables. But what exactly should they pay attention to?
How to attach cables to photovoltaic solar modules the right way
1. Avoid Cable Curves:
Prevent cables from sagging or bending excessively, as thermal expansion and wind-induced movement can lead to wear and eventual breakage.
2. Protect Cables Near Metal Edges:
Always use appropriate protective products to avoid damage to the cable sheath, which could result in short circuits or fires.
3. Use Proper Clips for Perforations:
Fasten cables securely using purpose-designed clips to ensure stability and prevent wear.
4. Opt for Edge Clips Over Drilling:
Edge clips eliminate the need to drill into panels, preserving cable insulation and protecting it from weather exposure.
5. Pay Attention to Floating PV Systems:
In systems exposed to water or moisture, ensure cables and connectors are adequately sealed and protected to prevent damage.
6. Select Correct Mounting Points:
Ensure mounting points match the number of solar modules to prevent cascading failures that could lead to energy loss or damage.
7. Use UV-Resistant Clamps:
Solar-specific clamps should withstand UV exposure and accommodate thermal expansion or vibration without failing.
8. Avoid Sharp or Exposed Edges:
Sharp edges can cut cables, potentially causing short circuits and compromising safety.
9. Ensure Proper Cable Routing:
Mismanaged cables can put strain on junction boxes, increasing the likelihood of maintenance issues and reducing system efficiency.
10. Follow This Checklist:
Referring to these guidelines during installation ensures a safer, more efficient, and reliable PV system.
By focusing on these 10 points, installers can achieve professional cable management, enhance system longevity, and reduce maintenance costs in solar plants.
