4 FAQs about Causes of alkaline corrosion of photovoltaic panels

Why is corrosion a problem in photovoltaic systems?

Pachuca—Tulancingo km. 4.5, Mineral de la Reforma 42184, Mexico The corrosion within photovoltaic (PV) systems has become a critical challenge to address, significantly affecting the efficiency of solar-to-electric energy conversion, longevity, and economic viability.

What is electrochemical corrosion in solar panels?

Electrochemical corrosion is the most common and insidious degradation process affecting solar panels. It involves redox reactions between solar cell's metal contacts and the surrounding environment. Moisture, humidity, and temperature fluctuations contribute to the formation of localized electrochemical cells on solar cell surfaces .

How does corrosion affect a solar cell panel?

Corrosion in solar cell panels can have severe con-sequences on their performance and durability. The figure highlights the detrimental efects of corrosion on various components of the solar cell panel. Moisture and oxygen enter through the backsheet or frame edges, as depicted by the arrows, and infiltrate the encapsulant-cell gap.

Why do solar panels corrode?

Moreover, sunlight's ultraviolet (UV) radiation can initiate photochemical reactions that exacerbate corrosion. Crevice corrosion occurs in confined spaces or crevices between different components of the solar panel assembly. These crevices trap moisture and pollutants, creating localized environments conducive to corrosion.
