What’s the best practice for cable management with flexible panels?

Secure Cable Routing

To prevent damage to flexible solar panels, cables should be routed along the edge of the panel or on the backside, using cable ties or clips spaced at 20-30 cm intervals. This keeps cables away from the panel’s electrical components and reduces the risk of water ingress. When using cable ties, ensure they are not too tight, as this can damage the cable or the panel’s backing material.

Cable Management Techniques

For longer cable runs, consider using cable management channels or conduits to keep cables organized and protected from the elements. A good rule of thumb is to use cable ties to secure cables to the panel or a nearby object, then use a cable clip or connector to manage the cable as it exits the panel. This keeps the cable tidy and prevents it from getting damaged or tangled.

Cable Length Limitations

To prevent voltage drops and efficiency losses, keep cable runs as short as possible. For most applications, a maximum cable run of 15 meters is recommended. If longer cable runs are necessary, use thicker gauge cables (e.g., 6mm or larger) to minimize voltage drops and maintain efficiency. Use a voltage drop calculator to determine the maximum cable length based on the panel’s power output and the cable’s resistance.
