The lifetime of a photovoltaic (PV) module is influenced by a variety of degradation and failure phenomena. While there are several performance and accelerated aging tests to assess design quality and early- or mid-life failure modes, there are few to probe the mechanisms and impacts of end-of-life degradation modes such as corrosion.
The damp heat test is the main accelerated test for corrosion in PV modules [, , , ]. However, the conditions are very aggressive – 85 °C and 85% relative humidity – and may overstress modules, inducing degradation that is not observed in field operation .
Corrosion in solar panels represents a significant challenge that can negatively impact their performance, durability and profitability. Therefore, it is critical to develop advanced materials that are corrosion resistant to ensure the efficiency and longevity of solar PV systems.
Moisture penetrating a photovoltaic (PV) module may react with the metallic components causing corrosion. In addition, acetic acid which is produced by hydrolysis of ethylene vinyl acetate (EVA), the most common encapsulant, may further degrade metallic components.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
