Technical FAQs 4

What is the degradation rate of solar power?

Two plants, representing 6.4% of the total involved power, have shown degradation rates above 0.5%/year due to cracked cells and hot spots. Last but not least, degradations of up to 4.3%/year have been observed in short periods of time due to PV modules' failure or destructive weather events for example.

What is the degradation rate of PV modules?

However, other studies show degradation rates closer to 0.2%/year. 4 - 9 The difference between assuming a degradation rate of 0.5%/year or 0.2%/year results in a difference of 3% of the energy yield of the PV plant during 20 years, meaning that it is of great importance to know the actual degradation rate of PV modules.

What causes PV module degradation?

Material interactions More often, material interactions with the encapsulant are a root cause for PV module degradation.

What is the degradation rate of PV cells?

Using descriptive statistics to summarize the reported degradation rates of almost 200 studies, they derived a median annual degradation rate of 0.9 %/year with the PV cell technology and the primary author's methodological choices as the main determinants of the observed heterogeneity among the reported rates.
