Identifying micro-cracks in solar panels using electroluminescence imaging is a vital process for maintaining solar energy efficiency. This imaging technique allows for the detection of small, often invisible cracks that can lead to significant energy loss or panel failures. These defects, while initially microscopic, can reduce power output by up to 2. 5% annually if left undetected. Among them, PID effect and hot spots usually appear after installation and operation of PV panels for a period of time.
