In 2009, the market scale of my country's solar led street light industry was 532 million yuan, and in 2013 it exceeded 5 billion yuan, 10 times that of 2009, which shows the rapid development speed. In 2016, it reached more than 20 billion. The forecast in 2019 will reach around 50 billion yuan. Why is the development of solar street lights so fast? What are the reasons behind this?
Everyone knows that many energy sources in the world are non-renewable, and energy supply is relatively tight. Many countries fight for non-renewable energy even at wars, and are also vigorously developing the application of renewable energy. Among them, solar energy is one of the inexhaustible green energy sources.
Solar energy has many advantages: safety, noise-free, pollution-free, solar power generation does not require energy problems, is not restricted by region, does not require fuel, no mechanical rotating parts, low failure rate, easy maintenance, short construction period, random specifications and sizes, which can be convenient Combine with architecture, etc. These advantages are beyond the reach of coal power generation, which saves resources and protects the environment. The rapid development of my country's society and economy has provided better development opportunities and space for the photovoltaic market. Driven by the market and ecological environment, my country's photovoltaic industry is bound to have a major development. The use of solar photovoltaic technology to produce new types of solar lighting is an important work in the recent popularization and application of photovoltaic system technology in civilian high-tech. A few days ago, the electricity used for lighting in our country has exceeded 12% of the total electricity consumption in the country, and 50 million new street lights are added every year. If 1% of them use solar street lights, it will save the country an additional 700 million kWh of electricity. It is equivalent to saving a 100,000 KW power plant every year without any pollution or consumption.
In China, the more popular solar energy utilization projects are solar water heaters, solar roof projects and solar road lighting. In recent years, the country's western development plan has helped many herders use solar energy to light, boil water, and watch TV. It is also known as a "power plant on horseback."
What are the advantages of comparing solar street lights with ordinary lamps?
1. Lifespan comparison: The lifespan 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 lifespan of low-pressure sodium lamps is 18,000 hours; 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. 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.
2. Safety comparison: Solar street light adopts 12-24V low voltage, stable voltage, reliable operation, and no safety hazards. It is an ideal product for ecological communities and road administration departments. There are many hidden dangers to the safety of electric circuit lights in the city. 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.
3. Installation comparison: When solar street lights are installed, there is no need to install complicated circuits, only a cement base needs to be made and fixed with galvanized bolts. There are complicated operating procedures in the construction of municipal electric circuit lights. First of all, a large amount of civil construction such as digging and laying pipes, threading in the pipes, and backfilling must be supplemented with cables, which consume a lot of manpower, material and financial resources. Finally, debugging is required. Once a problem occurs, it will cause a lot of consumption.
4. Post-maintenance: The city's electricity costs are high, and the circuit is complicated. It requires long-term uninterrupted maintenance of the circuit. The risk is also very high. It requires a lot of maintenance costs. Once a problem occurs, it will cause a lot of consumption.
In summary, solar street lights are green, environmentally friendly, and the first choice for sustainable development of road lighting! This is also the reason why solar street lights have developed so rapidly.
