1. Easy installation: When installing solar street lights, there is no need to install complex circuits. Only a cement base and a battery pit are made, and they can be fixed with galvanized bolts. No need to consume a large amount of manpower, material resources, or financial resources, simple installation, no need for wiring or excavation construction, and no concerns about power outages or restrictions..
2. Low investment: Solar street lights have a one-time investment and long-term benefits. Due to their simple wiring, they do not incur maintenance costs or expensive electricity bills. Recovering costs in 6-7 years and saving over 1 million in electricity and maintenance costs in 3-4 years. It can save the high electricity cost of city circuit lights, complex lines, and the need for long-term uninterrupted maintenance of the lines. In the case of unstable voltage, it is inevitable that sodium lamps are prone to damage, and with the extension of time, the aging of the circuit and maintenance costs increase year by year.
3. Good safety performance: Solar street lights are ideal products for ecological communities and road administration departments due to their use of 12-24V low voltage, stable voltage, reliable operation, and no safety hazards. No accidents such as electric shock or fire. The safety hazards of urban circuit lights are significant, and people's living environment is constantly changing. Road renovation, landscape engineering construction, abnormal power supply, and cross construction of water and gas pipelines have brought many hidden dangers.
4. Energy conservation and environmental protection: Providing electrical energy through solar photovoltaic conversion, which is inexhaustible and inexhaustible. No pollution, no noise, no radiation. Solar street lights can add new selling points to the development and promotion of noble ecological communities; Sustainable reduction of property management costs and reduction of shared expenses among property owners. In summary, the inherent characteristics of solar lighting, such as safety without hidden dangers, energy conservation without consumption, green environmental protection, easy installation, automatic control without maintenance, etc., will directly bring obvious advantages to the sales of real estate projects and the construction of municipal engineering.
5. Long lifespan: The lifespan of solar lamps is much higher than that of ordinary electric lamps, such as the main component of solar lamps - the solar cell module, which has a lifespan of 25 years; The average lifespan of low-pressure sodium lamps is 18000 hours; The average lifespan of low-voltage tri color energy-saving lamps is 6000 hours; The average lifespan of ultra bright LED is over 50000 hours; The lifespan of solar batteries is 2-5 years below 38AH; 3-7 years from 38-150AH. The product has high technological content, and the control system and accessories are all international brands with intelligent design, ensuring reliable quality. According to the regulations of the local price bureau, which charge a one-time maintenance fee of 6 yuan/square meter for street lamps based on the pure residential building area in regular residential areas, the initial investment for ordinary lamps is much higher than that for solar lamps. In summary, when compared comprehensively, the investment saving characteristics of solar lighting fixtures are quite obvious [3].
In the solar power supply system, the performance of the battery will directly affect the comprehensive cost, operation and service life of the system. In this scheme, the * * new 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 lifespan of five to ten years.
Adopting suitable positive and negative alloy formulas and active material ratios to make the battery more suitable for the cyclic charging and discharging characteristics of energy storage batteries.
The design of colloidal electrolyte effectively inhibits the rusting of active substances and the sulfation phenomenon of * * plates
