Technical advantages of solar street lights
1. Easy installation: When solar street lights are installed, there is no need to install complicated circuits, just make a cement base, make a battery pit, and fix it with galvanized bolts. There is no need to consume a lot of manpower, material and financial resources, the installation is simple, there is no need to wire or "open the belly" to dig the ground construction, and there is no concern about power cuts.
2. Low investment capital: Solar street lights are one-time investment and long-term benefits. Because of the simple wiring, no maintenance costs or expensive electricity bills are incurred. The cost will be recovered in 6-7 years, and more than 1 million electricity and maintenance costs will be saved in 3-4 years. It can save the high electricity cost of the city circuit lamp, the circuit is complicated, and the circuit needs to be overhauled for a long time without interruption. Especially in the case of unstable voltage, it is inevitable that the sodium lamp is fragile, and with the extension of the age, the aging of the line and the maintenance cost increase year by year.
3. Good safety performance: solar street light adopts 12-24V low voltage, stable voltage, reliable operation, and no hidden safety hazards. It is an ideal product for ecological communities and road administration departments. There will be no accidents such as electric shock or fire. There are many hidden dangers to the safety of electric circuit lights in the city. People's living environment is constantly changing, road reconstruction, construction of landscape engineering, abnormal power supply, and cross construction of water and gas pipelines have brought many hidden dangers.
4. Energy saving and environmental protection: Solar energy is used to provide electric energy, which is inexhaustible and inexhaustible. No pollution, no noise, no radiation. Solar street lights can add new selling points for the development and promotion of high-level ecological communities; it can continuously reduce property management costs and reduce the cost of public share of owners. In summary, the inherent characteristics of solar lighting, such as safety, no hidden dangers, energy saving, no consumption, environmental protection, easy installation, automatic control and maintenance-free, will directly bring obvious advantages for real estate sales and municipal engineering construction.
5. Long life: The life of solar lamps is much longer than that of ordinary electric lamps, such as the main components of solar lamps-the service life of solar battery components is 25 years; the average life of low-pressure sodium lamps is 18,000 hours; the low-voltage and high-efficiency three The average lifespan of primary color energy-saving lamps is 6000 hours; the average lifespan of ultra-bright LEDs is more than 50,000 hours; the lifespan of special solar batteries is 2-5 years below 38AH; 3-7 years for 38-150AH. The products are high in science and technology, and the control system and accessories are international brands, intelligent design, and reliable quality. In accordance with the regulations of the local price bureau of the regular community of “6 yuan/m2 for the maintenance of street lamps in a one-time charge based on the pure residential building area”, the initial investment of ordinary lamps is much higher than the initial investment of solar lamps. In a word, the characteristics of saving investment of solar lamps are quite obvious from a comprehensive comparison.
In the solar power supply system, the performance of the battery directly affects the overall cost, operation quality and service life of the system. In this solution, the latest energy storage colloidal battery jointly developed by the company and the Institute of Metal Research of the Chinese Academy of Sciences is selected. Compared with lead-acid batteries, it has the following outstanding features in design and manufacturing process:
The service life is super long, under normal circumstances, the service life is five to ten years.
The use of suitable positive and negative alloy formulations and active material ratios makes the battery more suitable for the characteristics of the use of energy storage batteries for cyclic charging and discharging.
The design of the colloidal electrolyte effectively inhibits the rust removal of the active material and the sulfation of the plates, thereby delaying the performance degradation of the battery during use. Greatly improve the battery's deep charge and discharge cycle life. Choose the fourth generation of LED light source for lighting products.
