While on the one hand it is difficult to assess in detail their impact on the overall efficiency and longevity of a solar panel, they are one of the main sources of malfunctioning or even inactive cells. However, micro cracks are nearly impossible to avoid and – in the long-run –will affect most solar panels, including ‘high quality’ ones.
Solar panel components endure strong UV radiation and temperature changes daily. When the back sheet of a solar panel is cracked, it shows that the components were not well chosen. This can lead to water vapor entering the panel and causing damage to the solar cells.
An example of solar panel back sheet cracking and delamination. In addition to the well-known PID and LID effects, panels can also suffer from more serious issues due to the breakdown of the encapsulant and protective layers that are supposed to protect the cells from the elements. The most common of these is back-sheet failure.
Hot spots and micro-cracks are not always visible to the naked eye, and often, the only way to determine if a solar panel is compromised is to use a specialised thermal imaging camera that will highlight the temperature difference between the various cells.
Solar panel components are exposed to intense UV radiation and temperature variations every day. Cracked backsheets are signs of poor component selection and can cause water vapour to enter module laminate to damage solar cells. A cracked backsheet cannot insulate solar cells from water damage.
The most common of these is back-sheet failure. While the front glass sheet protects the solar cells from rain, hail, dirt and debris, the white or black plastic back-sheet is designed to protect the rear side of the cells from water, humidity and scuffs.

Micro Cracks in Solar Modules: Causes, Detection and Prevention
Micro-cracks represent a form of solar cell degradation and can affect both energy output and the system lifetime of a solar photovoltaic (PV) system. The silicon used in solar PV cells is very thin (in the range of 180 +/- 20 microns) and hence is susceptible to damage easily if the PV module''s production and handling are not up to the ...
