With the increasing scarcity of the earth's resources, the investment cost of basic energy is rising, and various safety and pollution hazards are ubiquitous. As a kind of “inexhaustible and inexhaustible”, solar energy is getting more and more attention. Here we make a practical comparison of the effects of solar lighting and the use of commercial lighting.
Contrast 1: The installation of the mains lighting fixtures is complicated: there are complicated operating procedures in the mains lighting project. First, the cables must be laid. Here, a large number of basic projects such as trenching, laying down pipes, pipe threading, backfilling, etc. . Then carry out long-term installation and debugging. If there is any problem with any one line, it will be reworked in a large area. Moreover, terrain and line requirements are complex, and labor and auxiliary materials are costly.
Solar lighting is easy to install: when installing solar lights, there is no need to lay complicated lines, just make a cement base and then fix it with stainless steel screws.
Contrast 2: The electricity cost of the mains lighting fixtures is high: there is a fixed high electricity bill in the work of the mains lighting fixtures. It is necessary to maintain or replace the lines and other configurations continuously for a long time, and the maintenance cost is increasing year by year. Solar lighting fixtures are free of electricity: solar lighting fixtures are a one-time investment, without any maintenance costs, and can recover investment costs in three years, benefiting in the long run.
Contrast 3: The mains lighting has safety hazards: the mains lighting fixtures bring many safety hazards due to construction quality, landscape engineering renovation, material aging, power supply abnormality, and conflicts between water and electricity pipelines. There is no safety hazard in solar lighting: solar lighting is an ultra-low voltage product that is safe and reliable.
