Solar Photovoltaic (PV) cables are essential components of solar energy systems, converting the sun's energy into usable electrical power. They connect the solar panels to the inverter, which converts the direct current (DC) energy generated by the panels into alternating current (AC) energy for homes and businesses. Designed to withstand harsh outdoor environments and exposure to UV radiation, moisture, and extreme temperatures, these cables are rated for use in temperatures ranging from -40°C to 90°C, depending on the insulation material used.

The conductor material used in solar PV cables is typically copper or aluminium, and the size of the conductor is determined by the amount of current that needs to be carried and the length of the cable. The insulation material used is typically cross-linked polyethylene (XLPE) or ethylene-propylene rubber (EPR), which provides excellent electrical insulation properties and durability. Solar PV cables may also include an additional layer of protective covering, such as polyvinyl chloride (PVC) or cross-linked polyolefin (XLPO), to provide protection against physical damage and environmental factors.

Solar PV cables may also have a shielding layer made of aluminium foil or copper braid to protect against electromagnetic and radio frequency interference, which can cause signal distortion and reduce the efficiency of the solar power system. In summary, solar PV cables play a critical role in the safe and reliable transmission of electrical power in solar energy systems. Their durability, flexibility, and resistance to harsh environmental factors make them a necessary component in the harnessing of renewable energy.
