6 FAQs about [Photovoltaic panel worm pattern]

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” .

Do snail trails on photovoltaic modules cause chemical reactions?

Further chemical components probably being involved in the chemical reactions were identified. Snail trails on photovoltaic modules are a source of enormous concern to the solar industry as no scientific reports on the mechanisms producing this global phenomenon were previously available.

Do snail trails cause power degradation in urban photovoltaic energy systems?

It indeed caused power degradation in urban photovoltaic energy systems. In this work, the relationship between snail trails and micro-cracks is studied. Electroluminescence and infrared thermometer are used to find out the influence of snail trails on cell structure and performance.

How do you test a PV module for snail trails?

The has been several testing methods developed for susceptibility for snail trails. For example, a 50-100 hour damp-heat test at 85 °C and 85% relative humidity in combination with a forward bias current of 8 A has been shown to be able to create snail trails in susceptible PV modules . Figure 1: Photograph of a PV module with snail trails.

Do solar cells have snail trails?

That snail trails occurrence means solar cells should have micro cracks. In here, we contributed the snail trail effects and avoided the failures in future photovoltaic modules performance. The snail trails testing flow chart. . Module components for snail trails testing.

Are there snail trials in photovoltaic power plants?

And heavy snow pressure also caused the cracks. According to the above authors, there are a lot of snail trials in every photovoltaic power plant. But there is no snail trial in some photovoltaic power plant. According to our investigations, the snail trials phenomenon is random. It is not directly correlated with cell micro-cracks.
