The effect of moisture ingress on PV modules has been reviewed. The major environmental and climatic factors such as temperature, humidity, and UV radiation influence moisture ingress into PV modules.
What are the effects of moisture in encapsulant in PV modules?
Moisture in EVA encapsulant can lead to metal grids corrosion, delamination and discolouration of encapsulants, potential induced degradation, optical and adhesion losses. The present work is a review of literature on the causes, effects, detection, and mitigation techniques of moisture ingress in PV modules.
What causes high potential difference between solar cells and PV modules?
However, several factors can induce high potential difference between solar cells and the PV module frame due to electrochemical interactions (Carolus et al., 2019, Kwembur et al., 2020, Luo et al., 2017, Yamaguchi et al., 2020).
Some of these factors include module encapsulation and design, solar cell's anti-reflection coating, PV system electrical topology and inverter type, environmental/climatic factors (such as humidity, temperature, UV radiation, soiling, etc.), and grounding conditions of the front glass (Carolus et al., 2019, Luo et al., 2017, Naumann et al., 2019).
