Electroluminescence (EL) Imaging System
Uncover hidden photovoltaic defects with high-resolution, near-infrared mapping for precise quality assurance and performance optimization
Our EL Imaging system works like an X-ray for solar panels, using a high-performance Wide Spectrum (NoIR) camera to "see" internal flaws that are invisible to the naked eye. By running a small electric current through the solar cell, the device glows in the near-infrared spectrum; our specialized sensors capture this light to map out the cell's health in real-time. This allows you to instantly spot micro-cracks, broken finger lines, and inactive areas that would otherwise lead to power loss or total panel failure over time.Designed for both the lab and the production line, the system features a wide dynamic range and low-noise electronics to detect even the smallest drop in luminescence. By identifying these "hidden" shunts and material impurities early, you can filter out defective units before they leave the factory or get installed in the field. It is a fast, non-destructive way to guarantee that every module delivers its maximum rated power and stays durable for decades.

An ideal solution for researchers and industries working at the forefront of photovoltaic (PV) technology
Micro-crack Detection: Identify tiny cracks caused by mechanical stress during the stringing or lamination process. Soldering Defect Analysis: Spot "cold joints" or broken finger lines where the electrical contact is poor, preventing power loss before the panel is framed. Cell Sorting: Categorize cells based on their luminescence intensity to ensure uniform efficiency across a single module.
Carrier Lifetime Mapping: Study how long electrons survive in the semiconductor, which directly correlates to the cell's voltage potential. Impurity Analysis: Visualize how material impurities in the silicon ingot affect the final electrical output. Degradation Studies: Track how cells age over time under simulated environmental stress (Heat/Humidity/UV/Shading).
Health Audits: Perform spot-checks on a percentage of modules to ensure the "used" panels haven't developed extensive micro-cracking that will lead to a rapid drop in ROI.
Stop losing money on "invisible" solar defects that standard thermal cameras and visual inspections simply cannot see. By investing in our high-resolution EL Imaging system, you gain the ultimate peace of mind, transforming your quality control from guesswork into a precise, data-driven science. Whether you are a manufacturer preventing costly factory returns or a field engineer protecting long-term power yields, this tool allows you to identify micro-cracks and cell degradation instantly—before they turn into expensive system failures. It is the most cost-effective way to guarantee that every panel you touch is performing at its absolute peak, ensuring your solar assets deliver their maximum ROI for decades to come.
