6 FAQs about [The generation and impact of snail pattern on photovoltaic panels]

Do snail trails affect photovoltaic (PV) performance?

Assessment of snail trails affected photovoltaic (PV) after seven years of operation in the subtropical climate of India revealed various reliability and performance issues. The presence of bubbles along the snail trails, backsheet degradation, cell cracks, breakage, narrowing of metallic fingers, finger interruption and shunts were found.

Do snail trails indicate broader degradation concerns in PV modules and cells?

Performance losses in the snail trails affected PV modules and cells were attributed to various degradations that observed with snail trails. The findings suggest that the presence of snail trails could serve as an indicator of broader degradation concerns.

Are solar panels affected by snail trails?

Figure 1 : Typical photos of solar panels affecetd by snail trail (from maintenace of photovoltaics parks of SolarWay) Within a few years this kind of PV module defect became widespread. In 2012 it was reported that about 50% of all newly installed modules were more or less affected from “snail trails” .

How is Snail Trail degradation detected in solar cells?

To access snail trail degradation at the solar cell level, a module was selected through visual inspection and EL imaging. Then, the cells within the module were grouped based on the type of degradation observed with snail trail. Cells from each group were analyzed by utilizing microscopic imaging, EL imaging, DLIT imaging, and I-V characteristics.

Do snail trails affect field-exposed PV modules?

Addressing these gaps, this paper aims to investigate field-exposed PV modules affected by snail trails using various characterization methods such as visual inspection, current–voltage (I-V) characteristics, electroluminescence (EL) imaging, and dark-lock-in thermography (DLIT).

Why do solar cells have a Snail Trail?

It is presumed that these metal particles or moisture arise from chemical reactions involving the cell, metallic fingers, and/or encapsulant foil during the snail trail formation process. Proposed hypothesis is needed to further investigate to understand the underlying mechanisms of the snail trail occurance in solar cells.
