Now our country has a very serious problem, that is, the economic gap between cities and towns is still very large. Therefore, while improving the economic performance of the cities, we must not forget to promote the progress of the rural economy. The most important step is to promote the use of solar street lights on rural roads to provide light for rural roads at night. In fact, there are many places in the countryside where street lights are not installed. The streets are dark and you can't see the direction. This can easily cause residents to dislike going out, which is not conducive to economic development. This is not to say that the rural areas deliberately do not install street lights, mainly because the installation cost of ordinary street lights is too high and the construction is very troublesome, otherwise the power grid is difficult to reach and use. Therefore, to promote the use of solar street lights on rural roads, the construction and installation are simple, and the use of power grids is not required. It relies on the absorption of solar light and converts it into electric energy. It can facilitate the travel of rural residents. It can also save a lot of electricity bills and save money. Put it in other project applications to promote rural social and economic development.
