If solar street lights want to grow bright, they should also overcome various technical 'bottlenecks'

In recent years, solar garden lights and landscape lights have been used more and more widely, and solar street lights are gradually entering people's field of vision. It has been widely recognized by the society for its advantages such as no need to lay cables, no conventional energy consumption, and long service life. Many cities and villages have also begun to promote the use of solar street lights in some areas and some roads in the form of trials or demonstrations. certain effect. However, many industry experts have pointed out that there are some issues that need to be paid attention to in the promotion of solar street lamps at this stage: Although the use of solar lamps has become more and more widespread, there are still some technical problems in the power, light efficiency and service life of solar street lamps. Solar street lights are not only small in power and expensive, but the solar panels on the top are also easily affected by wind. Green shading, high-rise buildings and changing weather are all obstacles to the promotion of solar street lights. Relevant data shows that for a set of 150-watt solar street lights, the initial investment is about 15,000 yuan, while the cost of each set of conventional street lights is only about 8,000 yuan. Although solar street lights have a long service life, the maintenance and replacement costs are relatively high. The lead-acid batteries usually used in solar street lights have a service life of only 3-5 years. In addition, the photoelectric conversion efficiency of solar street lamp panels is low, currently only about 15%, which seriously affects the power generation efficiency of solar street lamps. In addition, the service life of solar panels also restricts the promotion and use of solar street lights. Experts said that the conversion rate of solar panels is low and the cost is high. If you want the lights to stay on for a longer time, you should improve the configuration and match the components reasonably, instead of simply increasing the battery capacity. Moreover, there are still some artificial shortcomings, such as the randomness of the system configuration, which greatly reduces the service life and lighting effect of the lamps. At present, many areas are piloting the promotion of solar street lights, especially in the construction of new rural areas in some areas, solar street lights are used on a large scale. However, as far as the current situation is concerned, the promotion of solar street lights is not a face project, and the local government should give continuous and planned financial and human support, otherwise the longevity of solar street lights will not be realized.
