Briefly describe the comparison results of solar street lights and ordinary street lights

　　 With the ever-decreasing of earth resources, the investment cost of basic energy is rising day by day, and various safety and pollution hazards can be said to be everywhere. As a kind of 'inexhaustible and inexhaustible' safe and environmentally friendly new energy source, solar energy has received more and more attention. In this way, solar lighting products came into being with the popularization of solar water heaters. Here, a practical comparison is made between the effects of solar street lamps and ordinary street lamps.　　Comparison 1: 　　Complex installation of general lighting street lamps: In general lighting street lamp projects, there are complicated operating procedures. First, cables must be laid. There must be a large number of basic works such as excavation of cable trenches, laying concealed pipes, threading inside the pipes, and backfilling. Then carry out a long-term installation and debugging, if any one of the lines has a problem, a large area of u200bu200brework is required. In addition, the terrain and lines are complex, and the labor and auxiliary materials are expensive.　　Solar street light is easy to install: when solar street light is installed, there is no need to lay complicated lines, just make a cement base and fix it with stainless steel screws.　　 Comparison 2: 　　 General lighting street lamps have hidden safety hazards: General lighting street lamps have many hidden safety hazards due to construction quality, landscape engineering transformation, material aging, abnormal power supply, conflicts between water and electricity pipelines, etc.　　Solar street lights have no safety hazards: solar street lights are ultra-low voltage products, which are safe and reliable in operation. Other advantages of solar street lights: green and environmental protection, can add new selling points for the development and promotion of noble ecological community; sustainable reduction of property management costs, reduce the cost of the public share of the owners.　　 Comparison 3: 　　 High electricity bills for general lighting street lamps: There are fixed and high electricity bills in the work of general lighting street lamps, and it is necessary to maintain or replace the lines and other configurations for a long time, and the maintenance cost is increasing year by year.　　Solar street lamps are free of electricity fees: solar street lamps are a one-time investment, without any maintenance cost, the investment cost can be recovered in three years, and long-term benefits.　　 To sum up, the characteristics of solar street lights, such as safety, no hidden dangers, energy saving, no consumption, environmental protection, simple installation, automatic control and maintenance-free, will directly bring obvious advantages to urban and rural construction.
