1, installation comparison
When the solar street lamp is installed, there is no need to set up a complicated circuit, only a cement base and a battery pit within 1m, which can be fixed by galvanized bolts.
There are complicated operating procedures in the construction of circuit lights in the city. First of all, it is necessary to provide a large number of civil constructions such as cables, trenching pipes, pipe threading, backfilling, etc., which consumes a lot of manpower, material resources and financial resources. Finally, debugging is required, and if there is a problem, it is very expensive.
2, cost comparison
Solar street lamps are invested once and benefited for a long time. Because the lines are simple, no maintenance costs are incurred and no expensive electricity costs are incurred. The cost will be recovered in 6-7 years, and the electricity and maintenance costs will be saved by more than 1 million in the next 3-4 years.
The city's circuit lights have high electricity costs and complicated lines, and it is necessary to maintain the lines for a long time without interruption. In the case of special voltage instability, the sodium lamp is easy to be damaged, and as the age increases, the line aging and maintenance costs are increasing year by year.
3, security comparison
Due to the low voltage of 12-24V, the solar street lamp has stable voltage, reliable operation and no hidden dangers. It is an ideal product for the ecological community and the road administration department.
The safety of circuit lights in the city is great. People's living environment is changing constantly. Road reconstruction, landscape engineering construction, power supply is not normal, and cross-construction of water gas pipelines brings many hidden dangers.
