Do micro cracks affect solar panels?

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.

To identify hot spots, you can use thermal imaging cameras or consult a solar professional who has the necessary equipment to conduct a comprehensive inspection.

Why are solar PV cells prone to micro-cracks?

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.
