Even slight imperfections in the PV cell can lead to large micro-cracks once it is incorporated into the PV module. The length of micro-cracks can vary; some span the whole cell, whereas others appear in only small sections of a cell. Micro Cracks in Solar Panel How do micro-cracks occur?
Three key areas must be addressed to effectively prevent solar panel micro-cracks: manufacturing, transportation/installation, and environment. Selecting a solar panel manufacturer that acknowledges the prevention of micro-cracks is a critical part of the solution.
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 required standards. Even slight imperfections in the PV cell can lead to large micro-cracks once it is incorporated into the PV module.
In a solar module production line, a poorly tuned stringing machine or manually soldered joints may exert excess forces during the soldering process and cause hairline cracks around the busbars. These cracks worsen after the lamination process, as both the pressure from lamination and thermal expansion cause the cracks to lengthen and widen.
The most common type of micro-cracks appears in the field, caused by constant wind stresses and heavy snow during long winters. The solution to the field defects is to structurally strengthen the solar cells.
In the production process, micro cracks most frequently occur during lamination of the panel, especially when using certain EVA films with weak moisture impermeability. If in such cases even slight moisture occurs it cannot easily evaporate which is particularly problematic in hot areas and environments.
