4 reasons why solar street lights are malfunctioning

   As a common road lighting lamp, the number of installations of solar street lights is increasing. With the increase in installation, the failure rate of solar street lights also increases. The failure rate of solar street lights is mainly due to the following 4 reasons.

  1. The quality of itself is not foreign

   At this moment, the market for solar street lights is fiercely competitive. In order to attract customers, many manufacturers have shoddy product quality. Although they use the same configuration in configuration, the price is much lower. For example: solar photovoltaic panels use low-quality panels and low conversion efficiency, resulting in low battery power, short battery playback times, poor controller quality, and so on.

  2, the design is unreasonable

The    solar street light system is not a standard configuration system, it is configured according to the requirements of each user, such as: night lighting time, number of rainy days, solar coefficient and so on. Unreasonable configuration of solar street lights makes the entire system overloaded, resulting in overheating of cables, overheating of wire noses, reduced insulation, and grounding short circuits. On the other hand, only the environment of the pole is considered when designing the pole, and the cable head is ignored. After the cable heads are wrapped, most of them cannot even close the door. Sometimes the cable length is not enough and the joints are not suitable for the requirements. This is also the cause of the failure.

   3. Poor construction quality

   The proportion of failures caused by construction quality is relatively large. The main indications are: First, the depth of the cable trench is not enough, and the construction of the sand-covering bricks is not carried out according to the scale; the second is that the production and installation of the aisle pipe are not suitable for the requirements, and the two ends are not made according to the scale; the third is when laying the cable. Dragging on the ground; Fourth, the basic embedded pipe is not constructed according to the requirements of the scale, mainly because the embedded pipe is too thin, coupled with the inevitable bend, it is quite difficult to pass the cable, and it presents a 'dead bend' environment at the bottom of the root; It is because the thickness of the wire nose crimping and insulation wrapping is not enough, it will short-circuit between phases after long-term operation.

  4. The quality of supporting projects is not extraordinarily hard

   Solar street light cables are generally laid on the green belt. The construction quality of the sidewalk is poor, and the ground sinks, which causes the cable to be deformed by force, which leads to the cable armoring. Especially the northeast region is in the high cold zone. The winter comes, so that the cables and the soil form a whole. Once the ground subsides, it will be strained at the bottom of the solar street lamp. In summer, when there is a lot of rain, Jiangsu Naite Lighting Electric Co., Ltd. is engaged in Produce and design solar street lamps, high pole lamp manufacturers, 20 years of solar street lamp production experience, to create the most professional solar street lamp manufacturer, contact number: 13805257308. , It will burn at the root.
