The rapid rural development has brought neat and bright street lamps to the roadsides and alleys. LED solar street lamps, which are easy to install and do not require wiring, are widely used in the construction of new rural areas.
LED solar street lamps mainly consist of five components: LED light head, light pole, solar photovoltaic panel, street light controller, and lithium battery.
The commonly used light heads in the construction of new rural areas come in various specifications such as 20W, 30W, 40W, and 50W. The higher the power, the better the brightness. From a cost perspective, a LED solar street lamp (40w) is generally sufficient to meet the lighting needs of rural roads.
The main function of the light pole is to hold the LED light head and the solar bracket, and it is generally a tapered pole. The height of rural solar street lights ranges between 4 to 7 meters; the material of the pole determines its lifespan. Common materials include hot-dip galvanized poles and galvanized poles, with the latter being more cost-effective but prone to rust. Hot-dip galvanized poles generally do not rust for up to 20 years. Common pole thickness specifications include 2.5MM, 2.75MM, and 3MM.
Commonly used panels include monocrystalline and polycrystalline silicon photovoltaic panels. Monocrystalline panels have higher photoelectric conversion rates and longer lifespans, but their production process and costs are relatively higher. Polycrystalline panels are more economical and practical for most applications.
This device, fully named as the solar charge-discharge controller, manages the work of the solar panels, batteries, and light head, making it a crucial component in the photovoltaic system. It ensures efficient and safe operation of the entire solar photovoltaic system.
Compared to the lead-acid batteries used in previous years, lithium batteries are widely adopted due to their smaller size, high energy density, long charge-discharge lifespan, and convenient installation. Common specifications include 3.2V, 12V, and 24V, with higher voltages corresponding to higher costs.
LED solar street lamps are road lighting devices that generate and store electrical energy from solar power for illumination. Compared to traditional street lights, solar street lights have the following features and advantages:
Environmentally Friendly and Energy Efficient: Solar street lights generate electricity using solar energy without requiring external power sources, and they do not emit harmful substances such as carbon dioxide, making them an eco-friendly and energy-efficient lighting choice.
Long Lifespan: Solar street lights use high-quality solar panels and battery packs, offering good durability and corrosion resistance for long-term use. The lifespan of a solar panel is 25 years, the super bright LED lights have an average lifespan of over 50,000 hours, and the specialized solar batteries can last 5-7 years.
Automatic Control: Equipped with light sensors and time controllers, solar street lights can automatically sense light intensity and time, enabling automatic switching and improving energy efficiency.
Easy Installation: The integration of battery panels, photovoltaic panels, and intelligent light brackets simplifies installation since no cables are needed, only a fixed cement base is required;
Low Cost: Utilizing natural energy, solar street lights incur no electricity costs and have no maintenance costs;
Safety Assurance: Equipped with anti-theft brackets and the ability to intelligently control the current, providing security assurance.
