2013 Complementary lighting method of solar street lights according 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 wrong positioning, blindly using them in the main roads of urban roads, roads in the city center or commercial centers, large transportation hubs and other locations, the result is that despite efforts, Since the electric energy provided by solar cells 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 street light solar photovoltaic power and mains complementary lighting method is a good way to solve the problems existing in the application of ordinary solar photovoltaic lighting systems in urban areas with mains electricity, especially in urban roads where lighting cables have already been laid. Street lights, there is absolutely no need to double the capacity of batteries and solar cells for several consecutive cloudy and rainy conditions that are rare every year. It is a waste most of the time each year. In this case, it is only necessary to consider the electric energy demand in the time period of the longest sunshine time in a year and the shortest lighting time at night, and other energy can be supplemented by the mains. In this way, the efficiency of the solar cell can be maximized, the capacity of the battery can be minimized, the system cost can be minimized, and the system reliability of the solar street light can be maximized. Therefore, if solar street lights are to be installed on roads where lighting cables have already been laid in the city, the complementary lighting method of solar photovoltaic power and mains electricity is a good way to adapt to local conditions. Solar street lights 1 In accordance with the requirements of Article 6.1.2 of the 'Urban Road Lighting Design Standards' CJJ45-2006 implemented on July 1, 2007, dual power supply must be achieved in important squares in the city, and solar photovoltaic power Complementary lighting with mains can not be said to be a bad method. In cities, the cost of dual-circuit power supply is quite high in some places. The complementary lighting of solar photovoltaic power and mains will greatly reduce the cost of dual-circuit power supply for street lamps.
