The solar cable is also called PV cable, which connects photovoltaic modules and inverters, and the cable is used in 600/1000V AC 1500V DC. Solar energy systems are often used under harsh environmental conditions, such as high temperature and ultraviolet radiation. Therefore, the solar cable is different from ordinary cables. In comparison, PV cables have the characteristics of temperature resistance, cold resistance, oil resistance, acid and alkali salt resistance, UV resistance, flame retardancy, and environmental protection.
