Solar Cables

Write to Us

Solar cable is the interconnection cable used in photovoltaic power generation. A solar cable interconnects solar panels and other electrical components in the photovoltaic system. Solar cables are designed to be UV resistant and weather resistant. It can be used within a large temperature range and are generally laid outside. All sizes of solar cables from 0.5 SQMM to 240 SQMM are available, SOLAR Cables are generally in three type of variety as stated below:
