Electroluminescence testing is a non-invasive method used to identify microcracks on site and help in proving the root cause – necessary for warranty disputes. EL testing is performed onsite, and modules do not need to be uninstalled in order for testing to take place. Testing takes place at night so production is not disrupted.
An EL image can show many types of cell-inherent defects, not only microcracks. The pass or fail criteria of the EL image depends on the type of crack and the quantity per cell or module. Figure 3. Layout of a solar panel supplier production line. Solar panels that fail EL imaging before lamination are usually taken out for re-work.
Taking an (EL) image of a PV module is similar to taking an X-ray. EL images reveal defects and microcracks in the inner structures of the solar cells that make up a PV module. EL technology allows asset owners to clearly identify the modules with cell damage that will likely cause underperformance or hot spots in the future.

1. What is Electroluminescence testing? When current passes through PV cells, light emission occurs. This phenomenon is called Electroluminescence. Testing of modules using this phenomenon can detect hidden defects in the structure of PV cells. This method makes the current distribution visible in the PV module and helps detect defects. With the help of an EL []
