1. Compare the life of solar street lights and traditional street lights:
The life of solar lights is much higher than that of ordinary lights. For example, the main component of solar lighting hardware components - solar modules have a lifetime of 25 years; low-pressure sodium lamps have an average life of 18,000 hours; low-voltage high-efficiency trichromatic energy-saving lamps have an average life of 6000 hours; super-bright LEDs have an average life of more than 50,000 hours. The life of solar cells is 2-5 years lower than 38AH; 38-150AH 3-7 years old. According to the regulations of the local community logistics bureau, “in accordance with the pure residential building area disposable residential street lamp maintenance fee of 6 yuan / m2", the initial investment of ordinary lamps is much higher than the initial solar lamp investment. In short, it is quite obvious to comprehensively compare the characteristics of solar lamps to save investment.
2. Comparison of solar street lights and traditional street lights:
Due to the low voltage of 12-24V, the solar street lamp has stable voltage, reliable operation and no hidden danger. It is an ideal product for ecological communities and road management. Traditional street lights have great security risks. People's living environment is constantly changing. Road reconstruction, landscape engineering construction, power supply is not normal, and cross-construction of water gas pipelines brings many hidden dangers.
3. Comparison of solar street lights and traditional street lights:
Solar street lights invest once and benefit in the long run. Because the line is simple, there is no maintenance cost and no expensive electricity bills. The cost will recover in 6-7 years, and power and maintenance costs will save more than 1 million in the next 3-4 years. Traditional street lamps have high electricity bills and complicated wiring, and require long-term uninterrupted maintenance of the line. In the case of particularly unstable voltages, sodium lamps are easily inevitable, and as age increases, line aging and maintenance costs increase year by year.
4. Comparison of installation of solar street lamps and traditional street lamps:
There is no need to set up complicated wiring when installing solar street lights. Only make a cement base and make a battery pit within 1 meter. Secure with galvanized bolts. There are complex operating procedures in traditional streetlight construction. First of all, it is necessary to provide a large number of civil buildings, such as cables, trenching pipes, pipe threading, backfilling, etc., which require a lot of manpower, material resources and financial resources. Finally, debugging is required, and if there is a problem, it is very expensive.
