As some brands cut corners on product quality to remain price-competitive, solar panels start to fail in the field before their expected lifetime is up. Here are 11 of the most common solar panel defects to watch out for in a solar installation, and how WINAICO works to prevent them from happening to your sites.

This paper develops a failure mode and effects analysis (FMEA) methodology to assess the reliability of and risk associated with polycrystalline PV panels. Generalized severity, occurrence, and detection rating criteria are developed that can be used to analyze various solar PV systems as they are or with few modifications.

Some of the most common solar panel defects include microcracks, which are small fractures that can form in the cells during manufacturing or transportation, potentially reducing efficiency. Another issue is solar panel delamination, where the layers within the module separate, allowing moisture to penetrate and causing a decline in performance.

Snail trails typically appear after only a few years and can have multiple causes, often attributed to lower-quality panels. Defects in these panels can allow moisture to enter through the back sheet, causing oxidation between silver paste, a key material used in manufacturing, and the encapsulation material.
