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.

  對比一市電照明燈具安裝復雜：在市電照明燈具工程中有復雜的作業程序，首先要鋪設電纜，這里就要進行電纜溝的開挖、鋪設暗管、管內穿線、回填等大量基礎工程。然后進行長時間的安裝調試，如任何一條線路有問題，則要大面積返工。而且地勢和線路要求復雜、人工和輔助材料成本高昂。太陽能照明燈安裝簡便：太陽能燈具安裝時，不用鋪設復雜的線路，只要做一個水泥基座，然后用不銹鋼螺絲固定就可。

    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.

  對比二市電照明燈具電費高昂：市電照明燈具工作中有固定高昂的電費，要長期不間斷對線路和其它配置進行維護或更換，維護成本逐年遞增。太陽能照明燈具免電費：太陽能照明燈具是一次性投入，無任何維護成本，三年可收回投資成本，長期受益。

    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.

   對比三市電照明燈具有安全隱患：市電照明燈具由于在施工質量、景觀工程的改造、材料老化、供電不正常、水電氣管道的沖突等方面帶來諸多安全隱患。

    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.

   太陽能照明沒有安全隱患：太陽能燈具是超低壓產品，運行安全可靠。太陽能照明的其它優勢：綠色環保，能為高尚生態小區的開發和推廣增加新的賣點；可持續降低物業管理成本，減少業主公共分攤部分的費用。

    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.
