The operation process of the solar power plant EL detector.
1. Preparations.
There is some preparation that needs to be done before proceeding with the EL test. First of all, make sure that the surface of the solar power station's panels is clean and free of impurities such as dust and dirt. If there is snow or ice on the surface of the panel, it needs to be cleaned first. Secondly, you need to prepare the EL detector and related tools, including probes, cables, power supplies, etc. Finally, it is necessary to understand the relevant parameters of the tested panel, such as voltage, current, power, etc.
2. Connect the instrument.
Connect the probes of the EL detector to the positive and negative electrodes of the panel to be inspected to ensure a secure connection. Then, connect the power supply of the EL detector to the probe and start the instrument. At this time, the instrument will automatically read the relevant parameters of the battery board, such as voltage, current, etc.
3. Detection operation.
After the instrument is started, the inspection operation is required. First, place the probe directly above the panel, adjusting the position and angle of the probe so that it can completely cover the surface of the panel. Then, press the "Start" button on the EL detector and the instrument will automatically perform the test. During the inspection, the instrument emits ultraviolet light through the probe to irradiate the surface of the panel and capture the reflected light. By analyzing the reflected light, it is possible to detect if there are defects or problems inside the panel.
Fourth, the results of the analysis.
After the test is completed, the EL tester will automatically generate the test result. By observing the inspection results, it is possible to determine whether there is a defect or problem in the panel. If there is a defect or problem, it needs to be dealt with and fixed accordingly. At the same time, the change trend of panel performance can also be analyzed by comparing the test results of different time periods.
5. Precautions.
When performing EL testing, the following points need to be noted. First of all, make sure that the surface of the panel is clean and free of impurities, so as not to affect the accuracy of the test results. Second, choose the right probe and cable to ensure that the instrument can work properly. At the same time, it is necessary to pay attention to the operation methods and precautions of the instrument to avoid damage to the instrument or injury caused by improper operation. Finally, it is necessary to carefully analyze the test results, accurately determine whether there is a problem with the battery panel, and deal with and repair it in time.
In short, the operation process of the solar power station EL detector needs to be carried out in accordance with certain steps. During operation, attention needs to be paid to details and precautions to ensure the accuracy and reliability of the test results. At the same time, it is also necessary to continuously accumulate experience, improve operational skills and levels, and provide better support and services for the maintenance and management of solar power plants.
