ソーラー街路灯はどのくらい持ちますか？

First of all, let's take a look at the main components of solar street lights: solar panels, LED light sources, batteries, street light controllers, light poles, etc. Batteries are further divided into lithium iron phosphate batteries, lead-acid batteries, UPS batteries, etc. Solar street light batteries need to have the characteristics of long life, strong deep discharge capacity, high charging efficiency, and good cycle capacity, which can effectively reduce the number of maintenance, but in practice In the application, customers often respond to the problems of frequent failures and short service life of solar street lights. This is because in the market competition, merchants have to reduce product quality in order to compete for the market price war, such as lithium iron phosphate batteries, which can be used under normal circumstances. Eight to ten years, but the batteries used in solar street lights may be recycled twice. Although this kind of solar street lights is cheap, the service life is very short, even only a few months! The life of the battery often determines the life of the whole lamp, and a good battery has a higher price.
