Urban installation of solar street lights should be adapted to local conditions
As a green energy source without any pollution, solar street lights are very suitable for road lighting, especially in areas without power supply or where it is difficult to lay power lines.

One of the main reasons that currently plague the development of solar street lights in cities is the positioning error. Blindly applying them to the main roads of the city, the roads of the city center or the commercial center, and the large-scale transportation hubs, the result is that despite the best efforts, Because the electric energy that solar cells can supply can not meet the illumination requirements of expressways, trunk roads and Yingbin roads, the application of solar cells in road lighting is currently mainly street lamps and garden lamps.

The solar photovoltaic power and mains complementary lighting method is a good way to deal with the problems existing in the application of ordinary solar photovoltaic lighting systems in urban areas with mains electricity, especially if solar street lights are to be installed on urban roads where lighting cables have already been laid. Not at all. Don't double the capacity of batteries and solar cells for the uncommon few times of continuous rainy conditions per year, it is a waste most of the time of the year. In this case, it is only necessary to consider the electric energy demand during the longest period of sunshine in a year and the shortest period of illumination at night, and other energy can be supplemented by the mains. In this way, the efficiency of the solar cell is maximized, the capacity of the battery can be minimized, the system cost is minimized, and the system reliability of the solar street light can be maximized.

Therefore, if solar street lights are to be installed on the way where lighting cables have already been laid in the city, it is a good way to adopt the complementary lighting method of solar photovoltaic power and mains electricity.
