A Review of the Degradation of Photovoltaic Modules for Life Expectancy

Photovoltaic (PV) modules are generally considered to be the most reliable components of PV systems. The module has a high probability being able perform adequately for 30 years under typical operating conditions. In order evaluate long-term performance diversified terrestrial conditions, outdoor-performance data should used. However, this requires wait 25 determine reliability, which is highly undesirable. Thus, accelerated-stress tests performed in laboratory by mimicking different field conditions important understanding module. paper, we discuss PV-module degradation types and that used reliability durability life expectancy before using them real field. Finally, prevention correction measures described minimize economic losses.
