Composition and Application of Solar Street Light with Sensor

Solar energy is a renewable, clean energy source that is inexhaustible and represents the inevitable trend of future energy utilization. With the widespread application of clean solar energy and the gradual maturity of energy storage technology,solar street lights with sensorsare gradually showing their advantages in road lighting and rural illumination, and replacing grid-powered street lights has become a trend.


Components of Solar Street Lights with Sensors


Solar Panel


The function of the solar panel is to convert solar energy into electrical energy that can be stored in the battery. Currently, monocrystalline panels have the highest conversion rate of17%, while polycrystalline panels have around12%.


Lithium Battery


The working principle of the lithium battery is that during the day it stores the electrical energy converted by the photovoltaic solar components, and at night it discharges according to control instructions. The quality and price of products from manufacturers with different technical capabilities can vary significantly.


Solar Controller


The quality of the controller directly affects the lifespan of the solar street light system. It is best to choose a branded one.


LED Light Source


Currently, better products on the market use flat lamp heads, and the light source can be selected with built-in heat dissipation.


Solar Street Light Pole


The pole part is customized according to the initial design requirements of the customer for the pole type and configuration parameters. Different size and style requirements significantly affect the price.


Application Fields of Solar Street Lights with Sensors


  • Road and street lighting in rural, township, and other peripheral areas.

  • Urban squares, parking lots, school playgrounds, workers' green spaces, and park lighting.

  • Lighting for golf courses, beach resorts, upscale villa areas, and more.

  • Replacement of highway warning signs, bridge street light power sources, and street lights.


Principles of Applying Solar Street Lights with Sensors


Practicality Principle


The main purpose of applying solar street lights in urban lighting systems is to save energy consumption. However, because they are greatly affected by weather factors, solar street lights may not fully meet lighting needs in cloudy and high-power-demand areas. Therefore, during application design, the original street light system design needs to be combined to increase solar power supply, achieving a complement of grid power and solar power to ensure timely switching to grid power when solar power is insufficient, thus improving the efficiency of the overall lighting system.


Efficiency Principle


During application design, it is necessary to improve the application efficiency through reasonable design based on meeting various functional needs of the lighting system. This simultaneously reduces system energy consumption and pollution, achieving energy-saving and environmental protection purposes. Additionally, for the application design of solar street lights, to ensure high application efficiency after implementation, it is essential to analyze local geographic and meteorological factors, such as sunshine duration, foggy weather, and rainy weather, thoroughly investigating and analyzing actual conditions. Adjust the design plan in real-time according to the actual situation to meet the lighting system's needs to the greatest extent.


Traffic Safety Principle


The primary purpose of constructing urban road lighting systems is to ensure traffic safety and, on that basis, improve transportation efficiency, providing a safe and comfortable environment for traffic operation. Therefore, in the construction and application ofsolar street lights with sensors, it is necessary to follow the traffic safety principle. Reasonable design based on the actual transportation needs of local road segments is essential, ensuring all aspects of the design meet usage requirements.
