How Do You Select A DC Wire For Solar Panels?

The DC wire for solar panels are placed outdoors so they need protection from extreme weather conditions, UV rays, pests etc. Solar panel distributors provide photovoltaic-certified solar cables that are best for your solar panels.

 

Here are some points to take into account when selecting wires for solar panels:

 

#1. Thickness

The diameter of the DC solar cable depends on the system voltage. The higher the voltage, the thinner the cable should be.

 

#2. Size

Solar panel distributors publish current ratings of cables based on their size. Select the right cable size to avoid overheating and voltage drop.

 

#3. Length

The length of the DC wire for solar panels is an important aspect to consider. For better   current transmission, the wire should be longer.

 

#4. Appearance

The outer layer of the wire or the insulating sheath layer should be smooth, glossy, and scratch-resistant.

 

#5. Wire Core

The core of the wire should be of pure copper material so it has good conductivity and superior performance.

 

 #6. Flame retardant

The wire should have flame-retardant properties to avoid fire in case of overheating.

 

#7. Temperature

The temperature also influences the performance of DC solar wires. The current carrying capacity of the wire reduces with increase in the temperature. So, make sure the solar panels are installed in a ventilated place.
