What is a crack in a solar cell?

Often cracks are named microcracks or µcrack, and all typically indicate a fracture in the solar cells in the range of mm to as small as in micrometres. Both terms usually suggest the same type of cracks where partially fully isolated areas are developed in the solar cells mainly due to mechanical or thermal stresses 3, 4.

What causes hot spots on solar panels?

Hot spots, one of the most common issues with solar systems, occur when areas on a solar panel become overloaded and reach high temperatures relative to the rest of the panel. When current flows through solar cells, any resistance within the cells converts this current into heat losses.

Can a cracked backsheet damage a solar panel?

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.
