Solar cable is cable type specially designed to be used in a photovoltaic power systems. These cable are high UV radiation resistant and operates in a wide range of ambient temperature (usually from -40°C up to 100°C). They are weather resistant and guarantee a long life operation. These single core cables are usually used to connect photovoltaic panels and inverters. They are available in range of diameters and current rating. The insulation is designed to withstand the extreme weather conditions such as low and high temperatures or resistant to acids and alkaline solutions in salt water environments. Using the correct cable types within the solar systems guarantee safety and high-quality operation over the years of usage. To eliminate the risk of ground faults and short circuits, the positive and negative cables should be laid separately.
