How to choose rural solar street lights?

With the accelerated development of new towns and the rapid development of road energy-saving renovation, the demand for solar street lights in rural road energy-saving renovation is also increasing. With the support of government policies, rural solar street lighting has become an important trend in rural road lighting. So how do choose rural solar street lights?

The rural solar street light is mainly composed of five parts: LED street light head, light pole, solar photovoltaic panel, controller, and lithium battery.

1. Light pole: The main function of the light pole is to fix the street lamp head and the solar bracket, which is generally a cone pole. The height of rural street lamps is generally between 4 and 7 meters, and the material of the lamp pole determines the life of the lamp pole. Commonly used light poles include hot-dip galvanized poles and galvanized poles. The cost of galvanized poles is relatively low, but they are easy to rust; hot-dip galvanized poles can generally be used for 20 years without rusting. Commonly used light pole thickness is 2.5MM.2.75MM.3MM and other specifications.

2. LED street lamp head: At present, the commonly used street lamp head in new rural construction has various specifications of power such as 20W/30W/40W/50W. The higher the power, the better the brightness. From the point of view of cost, the 30W solar street lights on rural roads can basically meet the needs of daily life. The core component that determines the quality of the street light head is the LED light source. The price of various light sources ranges from a few cents to a few dollars. Customers who pay attention to quality should choose a good light source.

3. Solar photovoltaic panels: commonly used monocrystalline silicon photovoltaic panels and polycrystalline silicon photovoltaic panels. Monocrystalline silicon solar panels have high photoelectric conversion efficiency and long service life, but the production process and cost are higher than those of polycrystalline silicon solar panels.

4. Solar controller: used in a solar photovoltaic system, its full name is solar charge and discharge controller, which coordinates the work of solar panels, batteries and street lamp heads, and is a very important component in photovoltaic systems. Make the whole solar photovoltaic system operate efficiently and safely. Some low-end solar street lights on the market do not have a controller, and the power of the controller is integrated into the LED street light head, so it can save some costs.

5. Lithium battery: Compared with the lead-acid battery used in previous years, lithium battery has the advantages of small size, high energy density, long charge and discharge life, and easy installation. It is widely used. There are several specifications of lithium batteries commonly used in the market, such as 3.2V/12V/24V. The cost of high-voltage lithium batteries is also high. In engineering, a 12V voltage system is commonly used.

The above information on how to choose rural solar street lights will be shared here. It should be noted that in the process of rural solar street lights installation, standardized management should be strengthened to promote rural solar street lights to achieve better cost and application in design.
