A solar panel is an assembly made up of multiple solar cells. It is the core part of the solar power system and the most important part of the solar power system. Solar hot spots can seriously damage the solar cell system, so hot spot detection on solar panels is very important. More and more solar panel professionals are beginning to use infrared thermal imaging cameras as solar panel inspection tools. The following is the working principle and precautions of using infrared thermal imaging camera to detect solar panels.

Working principle

Solar cells convert light energy into electrical energy and also generate heat. A failed battery will generate more heat. Under normal conditions, the temperature distribution of each cell is uniform. If there is an abnormally high temperature of individual cells in the component matrix, hot spots will be clearly displayed on the infrared thermal image, indicating that the cell may have a problem.

The advantages of infrared thermal imaging camera in solar panel inspection

(1) When the target circuit is detected by the thermal temperature cameras, there is no need to cut off the power, and the operation is convenient. The non-contact measurement method makes the original temperature field undisturbed.

(2) The image is more intuitive and fast, which can facilitate the inspector to obtain the temperature of different battery blocks on the same module at the same time and in the same environment, and it is easier to find hot spots.

(3) The response speed is faster, less than 1 millisecond.

(4) In addition to taking infrared images, users can also capture a visible light photo at the same time, and merge them together, which is helpful for time identification and fault location.

Precautions for testing

(1) Try to choose a temperature sensor cameras with higher sensitivity.

(2) The axis of the lens surface of the thermal cameras should be perpendicular to the target to be photographed.

(3) When shooting, the solar panel should be placed under normal sunlight or auxiliary light source to work, otherwise solar hot spots cannot be detected.

(4) Avoid the reflection of the auxiliary light source of the sun fire.
