太阳能电池板的寿命到底多长

钢化玻璃层压封装的太阳能电池板寿命为25 年，PET 层压封装的太阳能电池板寿命为5-8年，滴胶封装的太阳能电池板寿命为2-3年。现在市场上的太阳能电池板95%以上是钢化玻璃层压封装太阳能电池板。

光伏组件的寿命是由其发电效率决定的，而PN 结的结合程度和硅片的纯度决定了太阳能电池板在同样光的照射下产生电能的强度，随着时间的推移，PN结会不断破裂，这样效率会不断下降，15年后转换效率为90%以上，25年后将下降到85%左右，所以光伏且件的寿命基本在二十年以上。

Solar panels laminated with tempered glass have a life span of 25 years, solar panels laminated with PET have a life span of 5-8 years, and solar panels laminated with drip glue have a life span of 2-3 years. More than 95% of solar panels on the market today are solar panels that are laminated with tempered glass.

Photovoltaic modules of life is decided by its power generation efficiency, and degree of the combination of PN junction and the purity of silicon wafer determine the solar panels generate electricity under the same light intensity, with the passage of time, the p-n junction is broken, so efficiency will decline, 15 years after the conversion efficiency of 90% above, 25 years later will fall to about 85%, so the life of the photovoltaic (pv) and a base in more than twenty years
