Chang Hui analyzes the cause of the failure of solar garden lights

　　 1. Poor construction quality

　　 The failure of solar garden lights due to construction quality accounted for a larger proportion. Main performance: First, the depth of the cement base is not enough, and the sand-covered bricks on the edge are not constructed according to the standards; Second, the production and installation of solar courtyard light components do not meet the requirements; Third, the controller and battery wiring must be correct; Fourth, the foundation The embedded parts are not constructed in accordance with the standard requirements, mainly because the embedded parts and batteries are placed in place; fifth, the function of solar panels and batteries is not enough, and the light will flicker after a long period of operation.

　　2, the configuration materials are not enough

　　 Judging from the failure of solar garden lights handled in recent years, the quality of the controller is also a big factor. The main performance is: the wire contains less aluminum, the wire is relatively hard, and the insulation layer is thin. This situation has become more common in recent years.

　　3, the design is unreasonable

　　 On the one hand, it is overloaded operation. With the continuous development of urban construction, solar garden lights continue to extend. As an independent existence, solar garden lights do not have a well planned installation location and cause waste. In addition, the advertising industry has developed rapidly in recent years. Solar garden lights can be connected to the grid. The circuit and advertisement load are also connected to the solar garden lights accordingly, so that the solar garden lights are overloaded, consumed too fast, insulation is reduced, and ground short circuit occurs. On the other hand, only the light pole is considered in the design of the light pole. In its own situation, the space between the solar panels and battery lines is ignored. After the wire ends are wrapped, most of the doors cannot be closed. Sometimes the cable length is not enough and the joints do not meet the requirements. This is also the cause of the failure.
