Today's society is a dynamic one. With the increasing scarcity of traditional electricity, the use of solar energy is becoming more and more widespread, mainly in the field of power generation, which has developed into a mature sunrise industry in just a few years. Lithium solar street lights have also embarked on the "bright road" of socialism. How much do you know?
At present, one of the more important aspects that limit the use of solar energy is the price. Take a two-way solar street light, for example, the total load of two-way solar street light is 60 watts (estimated), the demand for its battery panel is about 160 W. Calculated at 40 yuan / watt, the cost of the battery panel is about 6400 yuan, the cost of the battery pack is about 2000 yuan, the one-time investment cost of the entire street light is much higher than the electric street light. It can be said that the price is the main bottleneck of solar street light application area.
The service life of the battery is also a factor for street lights. Most batteries have a warranty of three or five years, but generally the battery will not be fully charged after a year or even six months. In some cases, the charge rate may drop to about 50%, which will affect the normal lighting of street lights at night on consecutive rainy days. Therefore, it is more important to choose a better battery for the lithium solar street light.
The choice of controller is often overlooked by engineering companies, and the quality level of controllers varies. The water resistance of the controller also needs to be noted together. The controller is generally installed in the lamp cover and battery box, and generally will not enter the water. However, in the actual project, the connection line at the controller end is often short because rainwater flows into the controller along the connection line.
In areas far from urban areas, attention should also be paid to anti-theft operation. Due to construction negligence, many engineering companies fail to carry out better anti-theft, resulting in the theft of batteries, panels and other components, which not only affects the normal lighting of lithium solar street lights, but also constitutes unwanted property damage. Now in engineering cases, most of the stolen batteries are batteries, which are buried in the ground and poured with cement is a better anti-theft measure. If the battery box is installed on the lamppost, try to weld and fix it.
