How bright 20 w solar street light

Ordinary street lamps in the installer complex, need laying cable, must carry on the cable trench excavation, buried pipeline and line. In some places is bad of buried pipeline, the cost will be higher. Governor, leading one time installation and debugging, wasted a lot of manpower material resources. Moreover,

ordinary street lamp installation process complex, need for laying cable, mining cable conduit, buried pipes and wires. In some parts of the buried pipeline is difficult, but the cost will be higher. And installation time is long, waste a great deal of manpower, financial and material resources. In addition, the ordinary street lamp of electricity prices as prices rise. Run the plant also claims that the losses, it also requires constant maintenance lines. Embedded wire pose a safety hazard. If someone else in the underground construction of the pipeline, it might damage the pipeline, likely to cause safety accidents. Solar street light is easy to install, no need complex laid lines, just dig a small hole, a cement base, stainless steel screws. Solar street lamps, relying on solar energy into electricity, so after they built, almost no investment, only need to aging of daily maintenance and equipment maintenance. Although the purchasing cost is relatively high. However, after the cost would be slowly to recover. The service life of the solar street light is longer than the commercial street. Solar street light, however, there are also some shortcomings. No one can guarantee the rainy day lighting problems, such as battery life. But with the development of technology, these problems will be resolved soon. I believe that the future solar street lights will gradually replace the commercial street lamp.
