To lay the cable, here it is necessary to carry out cable trench excavation, laying hidden pipe, pipe threading, backfilling and a large number of foundation projects.Then carry out a long time of installation and debugging, if any line has a problem, it will be a large area of rework.And terrain and wiring require complex, costly labor and auxiliary materials.Solar lamp installation is simple: when solar energy lamps and lanterns is installed, need not laid complex line, want to do a cement base only, fix with stainless steel screw next ok.There are high fixed electricity charges in the work of municipal lighting fixtures, and maintenance or replacement of lines and other configurations should be carried out continuously for a long time. The maintenance cost increases year by year.Solar lighting free of electricity: solar lighting is one-time investment, no maintenance costs, three years can recover the investment cost, long-term benefit.Green environmental protection, can be noble ecological community development and promotion to add new selling points;Sustainable reduction of property management costs, reduce the owners of public share part of the cost.To sum up, the inherent characteristics of solar lighting, such as safety without hidden trouble, energy saving without consumption, environmental protection, easy installation, automatic control and maintenance-free, will directly bring obvious and exploitable advantages for the sales of real estate and the construction of municipal engineering.
