Technical advantages of solar street lamps

1. Easy installation: When installing solar street lamps, it is not necessary to install complex circuits. Instead, just make a cement base and a battery pit, and fix them with galvanized bolts. "It does not require a large amount of manpower, material resources, and financial resources to be consumed, and the installation is simple. It does not require stringing or" digging "the ground for construction, and there is no concern about power cuts and power restrictions."..
Low investment: Solar street lamps can benefit from one-time investment and long-term benefits. Due to their simple lines, they do not incur maintenance costs and expensive electricity bills. Recover costs in 6-7 years, and save over 1 million yuan in electricity and maintenance costs in 3-4 years. It can save the high electricity cost of municipal circuit lights and complex lines, requiring long-term uninterrupted maintenance of the lines. Especially when the voltage is unstable, it is inevitable that the sodium lamp is prone to damage. With the extension of the service life, the aging of the circuit and maintenance costs increase year by year.
3. Good safety performance: Solar street lamps are ideal for ecological communities and road administration departments due to their use of 12-24V low-voltage, stable voltage, reliable operation, and no potential safety hazards. There are no accidents such as electric shock, fire, etc. The potential safety hazards of municipal circuit lights are large, and people's living environment is constantly changing. Road reconstruction, landscape engineering construction, abnormal power supply, and cross construction of water and gas pipelines have brought many hidden dangers [1].
Energy conservation and environmental protection: Solar photovoltaic conversion provides inexhaustible and inexhaustible electrical energy. No pollution, no noise, no radiation. Solar street lamps can add new selling points for the development and promotion of noble ecological communities; Sustainably reduce property management costs and reduce the cost of public sharing by owners. To sum up, the inherent characteristics of solar lighting, such as safety, energy conservation, and consumption free, green and environmental protection, easy installation, and automatic control and maintenance free, will directly bring obvious and usable advantages to the sales of buildings and the construction of municipal projects.
5. Long service life: The service life of solar lamps is much higher than that of ordinary electric lamps, such as the main component of solar lamps - the solar cell module - with a service life of 25 years; The average life of low-pressure sodium lamp is 18000 hours; The average service life of low voltage and high efficiency three primary color energy-saving lamps is 6000 hours; The average lifetime of ultra bright LEDs is greater than 50000 hours; The service life of special solar battery is 2-5 years below 38AH; 3-7 years of 38-150 AH. The product has a high technological content, and the control system and accessories are all international brands, intelligent design, and reliable quality. According to the regulations of the local price bureau on "charging street lamp maintenance fees of 6 yuan per square meter per pure residential building area" in conventional residential areas, the initial investment of ordinary lamps is much higher than that of solar lamps. In summary, from a comprehensive comparison, the characteristics of saving investment in solar lamps are quite obvious [3].
In the solar power supply system, the performance of the battery directly affects the comprehensive cost, operation and service life of the system. In this scheme, the latest energy storage gel battery jointly developed by the company and the Institute of Metals, Chinese Academy of Sciences is selected. Compared with ordinary lead-acid batteries, it has the following outstanding features in design and manufacturing process:
The service life is extremely long, with a normal service life of five to ten years.
The use of suitable positive and negative electrode alloy formulations and active material ratios makes the battery more suitable for the use characteristics of cyclic charging and discharging of energy storage batteries.
The design of colloidal electrolyte effectively inhibits the rust removal of active substances and the sulfation of electrode plates, thereby delaying the degradation of battery performance during use. Greatly improving the deep charge and discharge cycle life of the battery. Select the fourth generation lighting product LED light source
