How to choose a solar cable


      As we all know, the thicker the cable, the lower the internal resistance. Although cables with larger wire diameters are more expensive, they can increase power generation revenue accordingly.

      Therefore, whether the cable is economical should be weighed and considered, and should not be swayed by the simple construction cost. In the solar system, the temperature of the AC cable is also different due to the different installation environment of the line. The distance between the inverter and the grid connection point is different, resulting in a different voltage drop on the cable. Temperature and pressure drop will affect the loss of the system. Considering all factors comprehensively, it is necessary to reduce the initial investment of the photovoltaic power station and reduce the line loss of the system.


      When making cable design and selection, technical parameters such as the rated current carrying capacity, voltage, and temperature of the cable are mainly considered. The outer diameter, bending radius, fire resistance, etc. of the cable are still considered when installing, and the cable is considered when calculating the cost. A suitable solar cable can greatly lose electricity costs.
