In fact, after several years of promotion and use, the advantages of wind-solar complementary street lights have long been known to more and more people. Since their use, they have always been the subject of research and attention, except for their use on urban roads. In addition to what kind of effect it brings, the price of wind-solar complementary street lamps has always been discussed. If it is expensive, it depends on all aspects. To say that the price of wind-solar complementary street lamps is higher than that of ordinary lamps, this is everyone knows. But if the construction cost of the input project is to be calculated in the entire project, the result is different. They are not much different in the initial investment cost. It is even possible that the price of ordinary lamps will be higher than the price of wind-solar complementary street lamps. If the project is larger and the construction work of ordinary lamps is higher, the investment cost will be higher than the price of wind-solar complementary street lamps, and the longer the use of wind-solar lamps, the more it can reflect its benefits. Subsequent use of electricity and maintenance costs are included together, and the cost of ordinary lamps will be higher than the price budget of wind-solar complementary street lamps.
