How long is the life of photovoltaic panels?

The service life of modern solar photovoltaic panels can generally reach 30 years or longer. Crystalline silicon photovoltaic panels can usually be used for 25-30 years. Some high-quality crystalline silicon battery modules can even reach 35-40 years. The service life of thin-film photovoltaic cells is slightly shorter than that of crystalline silicon, usually 20-25 years.

Modern photovoltaic panels will decay year by year during use, but the decay rate is very slow. Usually there will be 1-3% decay in the first year, and about 0.5% decay each year thereafter. After 30 years, photovoltaic panels can still maintain more than 80% of the initial power generation efficiency.

光伏板寿命有多长

现代太阳能光伏板的使用寿命普遍可以达到30年或更长。晶硅光伏板通常可使用 25-30年。一些优质的晶硅电池组件甚至可达35-40年。薄膜光伏电池的使用寿命较晶硅略短,通常为20-25年。

现代光伏板在使用过程中会逐年衰减,但衰减速度很慢。通常第一年会有1-3%的衰减,之后每年约0.5%的衰减。30年后,光伏板仍可保持80%以上的初始发电效率。
