Problems solved by technology

There is no doubt that solar technology will become one of the green energy technologies in the future. Solar energy or photovoltaic (PV) is widely used in China, and building cost-effective and profitable photovoltaic power plants represents the most important goal and core competitiveness of all solar manufacturers. , and its profitability not only depends on the efficiency or high performance of solar modules, but also depends on its important power transmission tool - photovoltaic cables. However, most photovoltaic power plants are built in desert areas with extremely harsh environments, and existing In this environment, the photovoltaic cables are not satisfactory in terms of weather resistance, ultraviolet resistance, ozone corrosion resistance and resistance to large temperature changes. Photovoltaic power plants need to replace cables frequently to ensure their own efficiency and stability. Greatly increased production costs, but also caused greater environmental pollution
