Disadvantages of ordinary street lamp: in the installation process is complex, need to lay cable, to carry out the excavation of cable trench, buried pipeline and line. In some places, it is difficult to bury pipelines, so the cost will be higher. And for a long time of installation and debugging, a lot of manpower, financial and material resources are wasted.
With the rise of electricity prices, the power station also claims that it is operating at a loss, and often has to maintain the lines.
There are hidden dangers in the buried line. If someone else works in the buried line, the pipeline may be damaged, which is easy to cause safety accidents.
Advantages of ordinary street lamp: not affected by the weather. It has no effect on the ground reaction with insufficient sunlight. Relatively speaking, the cost of street lamps is slightly lower.
Advantages of solar street lamp: simple installation, no need to lay complex lines, just dig a small pit, a cement base, fixed with stainless steel screws. Solar streetlights rely on solar energy to convert into electricity, so after the completion of almost zero investment, only need daily maintenance and equipment aging repair. Although the cost of procurement is relatively high. But the later cost will be recovered slowly. The service life of solar street lamp is longer than that of city circuit lamp.
But solar street lamps also have shortcomings. In rainy days, no one can guarantee the lighting, battery life and other issues. But with the progress of technology, these problems will be solved soon. I believe that solar street lamp will gradually replace the city circuit lamp in the future.
