With the advancement and maturity of solar energy technology, the current cost of solar street lights has been reduced, and the price is naturally not much different from that of ordinary street lights. However, solar street lights do not require electricity and are converted from sunlight. Their service life is 5 years. It can be used for about 500,000 hours and can save tens of thousands of kilowatt-hours of electricity every year. Compared with ordinary ones, the use of solar street lights is relatively cost-effective. In particular, our country has abundant solar energy resources. Solar street lights are widely used outdoor street lights, and the benefits produced by solar street lights are still considerable in terms of economic and social benefits. But despite the many advantages of solar street lights and how excellent its performance is, it is still in 'trial installation, trial, and testing' at the current stage of use, and has not been widely popularized. In recent years, the use of solar street lights has gradually decreased. The main reason is that many solar street light manufacturers are not thinking about how to continue to expand in the face of this huge market, but about how to grab customers and make a fortune. In order to retain customers, some manufacturers cut corners and cut corners in their products in order to retain customers. Over time, the quality of solar products purchased by consumers is not good enough. They gradually lose confidence in solar energy and reduce their use of solar street lights.
