Successful application of infrared thermal imager in photovoltaic module/single chip inspection
No.BN-BFF3FF1E
Based on many years of experience in the development of infrared products, the infrared thermal imager combines the advantages of various advanced infrared thermal imager products in the world. The latest developed high-end industrial detection infrared thermal imager integrates infrared, visible light, laser indication and other functions. In addition to its own complete analysis functions, the HY-G90 can also import the stored images into computer software through a PC card for further analysis. Moreover, the software can also achieve a direct connection between the thermal imager and the computer through the optional RS232 and USB2.0 interfaces, allowing computer remote control and high-speed image transmission. The appearance design of the HY-G90 infrared thermal imager is based on ergonomics, and it has added a top-mounted detachable remote control LCD screen. It is not only beautiful in appearance, but also has a top-mounted LCD screen
Excellent infrared imaging quality and accurate temperature measurement

The appearance design of the HY-G90 infrared thermal imager is based on ergonomics, and a top-mounted detachable remote control LCD screen is added. It is not only beautiful in appearance, but also the top LCD screen can be separated from the host to achieve split operation. Whether the user is in a factory, or in a small space or a corner that cannot be entered by the human body for inspection, the action is not restricted, which greatly improves the efficiency of the instrument.

Detachable full-function remote control handle with 3.5-inch color LCD screen
Adjustable color viewfinder
Built-in visible light digital camera (with video light, auto focus)
SAT infrared thermal imagers have ultra-high thermal sensitivity (NETD), which can sensitively and accurately sense tiny temperature changes on the surface of the object being tested, and detect defects in solar cells or components through non-contact detection. The defect location of the product is intuitively and accurately displayed in the infrared thermal image, providing users with a convenient and fast detection solution, which also makes infrared thermal imagers widely used in the photovoltaic field.
The solar cell production process is shown in the figure below. In the assembly stage, we use PV cells to weld and laminate them into modules.
Battery component defects need to be tested before leaving the factory. The main methods currently used are: 1 , battery panel electrical performance test; 2 , EL Visual detection of hidden cracks; 3 , infrared inspection after lamination. We mainly introduce infrared inspection of comprehensive defects of solar panels. When the solar panel passes reverse current, the panel will heat up. The impedance of the defective part of the panel is relatively large, so the heat generated is also large. We use infrared thermal imagers to observe the hot and cold areas of the panel. Normal situation The normal area is larger, the overheating area is the defect of the solar panel, and the overcooling area is the short circuit area of the solar panel. Therefore, both overheating and overcooling are problematic.
For the testing of solar cells and modules, we recommend the use of HY-G90, HY-6800 and other models.
