What is the reliability requirements when purchasing PV connector

 PV connector as an integral part of the solar battery component, it should be in poor contrast variation in the environment and climate conditions. Although the environment in different parts of the world's climate varies, and the same area of the environment and climate change is also a great contrast, but the materials and products for the environment and climate impact, summed up in four major factors: First, solar radiation, especially ultraviolet for plastics, rubber and other polymer materials, the impact; followed by the temperature, in which high and low temperature materials and products for more severe test; addition is the humidity rain, snow, condensation, etc., and other pollutants such as acid rain, ozone the impact of the material. Furthermore, the connector is to require a high performance electrical safety protection, and life must be more than 25 years; so photovoltaic connector performance requirements are:
1) the structural safety, reliable, easy to use;
2) high resistance to environmental climate indicators;
3) high sealing requirements;
4) High electrical safety performance;
5) high reliability;
