EL Testing: Ensuring Reliable Solar Panels
EL inspection, also known as electroluminescence imaging, is really helpful for finding tiny cracks, broken cells, and other issues that can make solar panels less efficient and shorten lifespan.
Electroluminescence (EL) Testing identifies microcracks in your modules and can help in identifying the root cause. Microcracks are present in most solar installations, but catching severe microcracks and removing them early can prevent considerable performance issues and investment losses.
Let's take a closer look at how EL testing is part of making solar panels. 1. Cell Fabrication: During the initial cell fabrication stage, EL testing can be used to identify and address defects or variations in the solar cell manufacturing process, ensuring consistency and optimal performance.
This laboratory can test more than 200 photovoltaic modules per day with an uncertainty of less than 3%. Due to its characteristics, it is capable of testing modules of up to 1400 x 2700 mm of different types (high efficiency crystalline modules, bifacial modules, thin film modules and PERC or HJT solar cells).
Electroluminescence solar module testers are designed with a range of features to optimize the testing and analysis of solar panels. Some of the key features include: 1. High-Resolution Imaging: EL testers use really good cameras to take detailed pictures of how light comes out of a solar panel.

Developer spent $150M on a solar project with undetected microcracks, which grew and worsened over time. CEA was later hired to conduct EL inspections, and found microcracks on 20%
You can trust EL inspection to keep your solar panels safe and working well. Tip: Doing EL inspections often helps you find hidden problems and keeps your solar panels working their best.
