About Solar panel EL test
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.
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.
At its core, EL testing is a diagnostic process that identifies imperfections or flaws within a solar panel’s cells, often invisible to the naked eye.
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 a process that makes use of image analysis and measurement, which enables sight directly into the solar cells to locate inherent potential defects.

6 FAQs about [Solar panel EL test]
Why do solar modules need El testing?
Due to its importance, solar module manufacturers frequently undertake EL testing twice during the manufacturing process. If left unchecked, cold soldering can develop into hot spots, lowering the module’s power and causing a fire risk. Figure 3: Sample module with soldering defects
What is on-site El Solar testing?
On-site EL solar testing, however, illuminates these hidden flaws, revealing micro-cracks, cell breakages, and other imperfections through a detailed examination of a cell's internal condition via electroluminescence imaging as seen in Figure 2.
What is an electroluminescence solar module tester?
The electroluminescence solar module tester is a key tool for manufacturers to check and improve solar panel performance. If you are interested in solar energy or work in the solar industry, this guide will help you learn more about the machine used in making solar panels.
Are all modules El tested?
All modules are EL tested by manufacturers at the end of the production line, alongside IV and Hi-pot tests. 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.
Are in-situ measurements a good way to measure solar module performance?
Traditional quality control methods such as electrical safety checks and visual inspection have been the cornerstone of in-situ measurements at PV power plants to ensure solar module efficiency for years. However, these methods often lacked the precision to identify internal defects that could compromise module performance.
Why do we need a solar module tester?
This light helps us see problems and flaws in the solar cells that we can't normally see with our eyes. The electroluminescence solar module tester is a key tool for manufacturers to check and improve solar panel performance.
