Sharing of skills in identifying solar panels

Solar panels play a vital role in the field of new energy. As long as solar products require solar batteries, they are widely used: solar street lights, solar garden lights, solar lawn lights, wind-solar street lights, solar power generation systems, etc. The solar panels are very much related. The quality of solar panel components is directly related to the performance of solar lighting equipment. As there are many solar panel manufacturers, and there are many low-quality solar panels, some ordinary users do not know solar panels very well, and they may have a headache when purchasing solar panels, so solar street lamp manufacturers will give it to everyone Introduce how to judge the quality of solar panels. First, look at the front: carefully check the surface of the tempered glass. In order to increase the production speed, some solar panel manufacturers often do not care about the silicone that accidentally drips on the surface of the tempered glass. If it is not removed, it will affect the power generation efficiency of the panel. Second, look at the cells: many irregular manufacturers use broken cells to splice together to form seemingly complete cells for welding. This method has a great risk, which may not be obvious in the early stage, but the spliced u200bu200bcells are easy in the later stage. Disconnect again, affecting the use of the entire battery board. Third, look at the back: Look at the effect of the back pressure, whether there are any unevenness after pressure, such as bubbles, wrinkles and the like. This kind of solar panel is unqualified. Fourth, look at the silica gel: check whether the silica gel is evenly distributed around the back and whether it penetrates into the gap between the backplane and the frame. Fifth, look at the frame: Many manufacturers use manual framing. Manual framing cannot guarantee that the force will be just right every time. The tightness of the framing is different, the shape is not strictly rectangular, and the firmness is greatly reduced. Sixth, look at the welding: carefully observe whether there is any leakage in the series welding of the battery slices. At the same time, it also depends on whether the cell arrangement is regular. Seventh, look at the junction box: Finally, see whether the junction box is firm and whether the junction box cover can be firmly and tightly attached to the junction box; see whether the wire lock head can rotate freely and whether it can be tightened. The above are the main points of how to identify solar panels in solar street lights. We have to judge the quality from the subtleties. I hope that the above points can be helpful to you, to better understand solar panels, so that ordinary users can also well identify the quality of solar panel components.
