Solar Panel Detection Method

Solar panels play a vital role in solar photovoltaic systems, and their performance directly affects the efficiency and stability of the entire system. Therefore, the correct detection of solar panels is essential. Here are some commonly used detection methods:

Visual inspection: Check the surface of the solar panel for obvious damage, scratches, stains, etc. by the naked eye. This approach, while simple and easy, may overlook minor pitfalls.

Electrical performance test: use professional photovoltaic test equipment to test the electrical performance of solar panels, including testing current, voltage, power and efficiency and other indicators. This method can detect whether the performance of solar panels meets the standard, but requires specialized equipment and skills.

Infrared thermographic inspection: The use of infrared thermography equipment to inspect solar panels, can detect the temperature distribution on the surface of the solar panel, so as to find possible defects. This method is more accurate, but requires specialized equipment and skills.

Tempered glass inspection: carefully check whether there is silica gel on the surface of tempered glass, and if the silica gel is not removed, it will reduce the power generation efficiency of photovoltaic panels.

Cell inspection: check whether the battery is complete, whether there is any broken phenomenon, and whether the welding is firm. At the same time, it is also necessary to check whether the arrangement of the battery cells is regular and whether there is any leakage of welding.

Backside pressure-bearing quality inspection: observe the pressure-bearing quality of the back of the solar panel, if there are unevenness, bubbles, folds, etc., it means that the pressure-bearing quality is not good.

Border inspection: check the tightness of the solar panel frame, if the contact tightness is inconsistent, it means that the firmness of the frame needs to be improved.

Silicone inspection: Check whether the silica gel around the back of the solar panel is evenly distributed and whether it closely penetrates into the gap between the back plate and the frame

Through the above detection methods, the quality and performance of solar panels can be comprehensively evaluated. In the testing process, it is necessary to pay attention to details and strictly follow the standards to ensure that the quality and performance of solar panels meet the requirements. At the same time, it is also necessary to pay attention to safety to avoid accidents during the detection process.
