This is a major quality control issue. If you are reviewing panels, you want "PID-resistant" and "High PID" rated modules that use thicker glass or half-cut cell technology to mitigate the impact of cracks. If you are buying budget panels, the risk of micro-cracks is significantly higher than with Tier 1 manufacturers (like Trina, Jinko, Longi).
A "PV crack" refers to a fracture in the silicon wafer of a solar cell. These are invisible to the naked eye but detectable via Electroluminescence (EL) testing.
