1. Simple installation: when installing solar street lamps, there is no need to set complex lines, just make a cement base and a battery pit, which can be fixed with galvanized bolts. It does not need to consume a lot of manpower, material and financial resources, and the installation is simple. There is no need for stringing or "rifling" excavation construction, and there is no concern of power outage and power restriction..

2. Less investment: solar street lamps are invested once and benefit for a long time. Due to the simple line, there are no maintenance costs and expensive electricity charges. 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 municipal circuit light and the complex circuit, which requires long-term uninterrupted maintenance of the circuit. Especially in the case of unstable voltage, it is inevitable that the sodium lamp is easy to break, and with the extension of service life, the line aging and maintenance costs are increasing year by year.

3. Good safety performance: due to the 12-24V low voltage, the solar street lamp has stable voltage, reliable operation and no potential safety hazards. It is an ideal product for ecological communities and road administration departments. No electric shock, fire and other accidents. There are great hidden dangers in the safety of municipal circuit lights. Under the constantly changing living environment, many hidden dangers are brought by road reconstruction, landscape engineering construction, abnormal power supply, cross construction of water and gas pipelines, etc.
4. Energy conservation and environmental protection: provide electricity with solar photovoltaic conversion, which is inexhaustible. No pollution, noise and radiation. Solar street lamps can add new selling points for the development and promotion of noble ecological communities; The cost of property management can be reduced sustainably, and the cost of the owner's public share can be reduced. To sum up, the inherent characteristics of solar lighting, such as safety without hidden dangers, energy saving without consumption, green environmental protection, simple installation, automatic control and maintenance free, will directly bring obvious advantages to the sales of real estate and the construction of municipal engineering.
5. Long service life: the service life of solar lamps and lanterns is much higher than that of ordinary electric lamps and lanterns, such as the service life of solar cell modules, the main components of solar lamps and lanterns, is 25 years; The average service 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 life of ultra bright LED is more than 50000 hours; The service life of special solar battery is 2-5 years below 38ah; 3-7 years of 38-150ah. The product has high scientific and technological content. The control system and accessories are international brands, intelligent design and reliable quality. According to the regulations of the local price bureau, "a one-time charge of 6 yuan / ㎡ for the maintenance of street lamps in the community based on the pure residential building area" in the conventional community, the initial investment of ordinary lamps is much higher than that of solar lamps. In short, from a comprehensive comparison, the characteristics of saving investment in solar lamps are quite obvious.
