With the increasing scarcity of the earth's resources and the increasing cost of investment in basic energy, various security and pollution risks can be described as ubiquitous. Solar energy as a "inexhaustible, inexhaustible" new energy of safety and environmental protection has been paid more and more attention. In this way, solar lighting products came into being with the popularization of solar water heaters. Here, we make a practical comparison between the effects of solar lamps and the use of municipal electric lamps.
对比一市电照明灯具安装复杂：在市电照明灯具工程中有复杂的作业程序，首先要铺设电缆，这里就要进行电缆沟的开挖、铺设暗管、管内穿线、回填等大量基础工程。然后进行长时间的安装调试，如任何一条线路有问题，则要大面积返工。而且地势和线路要求复杂、人工和辅助材料成本高昂。太阳能照明灯安装简便：太阳能灯具安装时，不用铺设复杂的线路，只要做一个水泥基座，然后用不锈钢螺丝固定就可。
Comparing with the installation of electric lighting fixtures in a city, there are complicated working procedures in the lighting fixtures project. First of all, cable should be laid. Here, a large number of basic projects, such as cable trench excavation, buried pipe laying, pipeline crossing and backfilling, should be carried out. Then long-term installation and debugging, if any line has problems, large areas of rework. Moreover, the terrain and line requirements are complex, and the cost of manual and auxiliary materials is high. Solar lighting installation is simple: Solar lighting installation, do not need to lay complex lines, as long as a cement base, and then fixed with stainless steel screw.
对比二市电照明灯具电费高昂：市电照明灯具工作中有固定高昂的电费，要长期不间断对线路和其它配置进行维护或更换，维护成本逐年递增。太阳能照明灯具免电费：太阳能照明灯具是一次性投入，无任何维护成本，三年可收回投资成本，长期受益。
Compared with the high electricity charges of the electric lighting lamps in the two cities, there are fixed high electricity charges in the work of the electric lighting lamps in the two cities. The maintenance or replacement of the lines and other configurations should be carried out uninterruptedly for a long time, and the maintenance cost increases year by year. Solar lighting is free of electricity charges: Solar lighting is a one-time investment, without any maintenance costs, three years can recover investment costs, long-term benefits.
对比三市电照明灯具有安全隐患：市电照明灯具由于在施工质量、景观工程的改造、材料老化、供电不正常、水电气管道的冲突等方面带来诸多安全隐患。
Compared with the three city electric lighting lamps, the city electric lighting lamps have many potential safety hazards, such as construction quality, landscape engineering transformation, material aging, abnormal power supply, water and gas pipeline conflict and so on.
太阳能照明没有安全隐患：太阳能灯具是超低压产品，运行安全可靠。太阳能照明的其它优势：绿色环保，能为高尚生态小区的开发和推广增加新的卖点；可持续降低物业管理成本，减少业主公共分摊部分的费用。
Solar lighting has no potential safety hazards: Solar lamps are ultra-low voltage products, safe and reliable operation. Other advantages of solar lighting: green 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 public share of owners.
