Accordingly, research must more and more focus on photovoltaic modules degradation. This paper presents a review of different types of degradation found in literature in recent years. Thus, according to literature, corrosion and discoloration of PV modules encapsulant are predominant degradation modes.
The analysis of degradation mechanisms of photovoltaic (PV) modules is key to ensure its current lifetime and the economic feasibility of PV systems. Field operation is the best way to observe and detect all type of degradation mechanisms.
1. Introduction Utilizing solar PV to generate energy is not a simple operation due to degradation, which can result in a reduction in solar PV performance and efficiency [1, 2]. According to recent studies, the rate of degradation varies between 0.6% and 0.7% per year [3, 4].
Subsequently the primary stress factors that affect module degradation were summarised; this includes irradiance, temperature, moisture, mechanical stress, soiling and chemicals. Finally, common degradation and failure modes were identified that occur generically in photovoltaic technologies were reviewed.
Osterwald et al. (2002) argue that the slow module degradations in the long term are linearly correlated to exposure PV modules under UV radiation. These last years, most papers on degradation of silicon crystalline PV modules were focused on the EVA degradation (Kempe, 2006, Kempe et al., 2007, Kempe, 2010).
The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradation and failure phenomena.
