solar cables, like ordinary cables, generally do not require frequent replacement. The requirement of TUV or UL standards is a service life of at least 25 years. Due to the use of high-purity tin plated copper conductors in solar cables, which have low resistance values, they are more resistant to oxidation than other pure copper wires.
The insulation and sheath of solar pv dc cable are made of XLPO materials that are resistant to high and low temperatures. The production process also requires irradiation technology, which has the characteristics of weather resistance, cold resistance, high temperature resistance, friction resistance, UV resistance, and ozone resistance, ensuring its superior durability and long-term stability. For solar cables, durability is an important aspect in extreme weather conditions, as they have the ability to withstand temperatures ranging from -40 degrees Celsius to 125 degrees Celsius, to adapt to various extreme weather conditions on Earth.
Although the service life of photovoltaic cables mainly depends on their design and manufacturing quality, in actual use, the service life of cables is also affected by the installation environment. For example, if cables are used in harsh environments such as high temperatures or areas with strong ultraviolet radiation, their lifespan may be affected. However, in general, the design and usage guidelines for solar cables recommend a service life of at least 25 years
