Solar energy, as a new renewable energy, has the advantages of clean, environmental protection, sustainability, and long-term. It has become one of the important choices for people to cope with energy shortages, climate change, and energy conservation and emission reduction. It is an inevitable trend of future energy utilization. With the widespread application of clean energy solar energy and the gradual maturity of energy storage technologies, the advantages of solar street lamps in road lighting and rural lighting have gradually emerged, and it has become a trend to replace city circuit lights through cables.
The working principle of solar street lamps is to convert solar energy into electric energy to achieve lighting. The top of the street lamp is a solar panel, also known as a photovoltaic module. Under the control of an intelligent controller, the solar street lamp is made of polycrystalline silicon photovoltaic modules to convert solar energy into electrical energy storage during the day. In the storage battery, the solar cell panel is irradiated by sunlight, absorbs the solar light and converts it into electrical energy, and the solar cell module charges the storage battery pack during the day. In the evening, the electric energy is transmitted to the light source through the control of the controller, which illuminates people at night. At night, the battery pack provides power to the LED light source to realize the lighting function.
Solar street lights generate electricity through solar energy, so there is no cable, no leakage and Other accidents will occur. The DC controller can ensure that the battery pack is not damaged due to overcharge or overdischarge, and also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection. No need to lay cables, no AC power supply, no electricity charges.
A series of advantages such as low-carbon environmental protection, safety and reliability of solar street lamps have been recognized by customers and have been vigorously promoted. Therefore, it can be widely used in urban primary and secondary arterial roads, communities, factories, tourist attractions, parking lots and other places.
The main purpose of solar street lamps in urban lighting systems is to save energy consumption, but because of its greater influence by weather factors, for cloudy days and areas with high power requirements, solar street lamps may not fully meet the lighting needs. Therefore, in the application design, it is necessary to combine the design effect of the original street lamp system, increase solar power supply, realize the complementarity of the mains power supply and the solar power supply, ensure that the solar power supply can be switched to the mains power supply in a timely manner, and improve the overall lighting Application efficiency of the system.
In the application design, on the basis of meeting the functional requirements of the lighting system, it is necessary to improve its application efficiency through rational design, reduce pollution while reducing system energy consumption, and achieve energy-saving and environmental protection purposes. In addition, for the application design of solar street lights, in order to ensure that it has a relatively high application efficiency after it is put into use, it should also do a good analysis of the local geographical factors and meteorological factors of the project, and analyze the sunshine time, haze weather and rainy weather, etc. Detailed investigation and analysis of the actual situation, combined with the actual situation to adjust the design plan at any time, and strive to meet the needs of the lighting system to the greatest extent.
The main purpose of urban road lighting system construction is to ensure traffic safety, and on this basis to improve traffic efficiency, provide a safe and comfortable environment for traffic operation. Therefore, in the construction and application of solar street lamps, the principle of traffic safety must be followed. Combined with the actual needs of local road transportation, a reasonable design is carried out. Ensure that all aspects of the design meet the requirements for use.
Solar street lights can add new selling points for the development and promotion of noble ecological communities; sustainable reduction of property management costs and reduction of the cost of the owners' public allocation. The inherent characteristics of solar lighting will directly bring obvious advantages to the sales of real estate and the construction of municipal projects.
