How to ensure the quality of solar street lights?

Solar street lights are mainly composed of 5 major components, namely solar panels, led light sources (other 12v or 24v light sources can also be used, but the overall luminous efficiency is not as good as led light sources), batteries, controllers, and light poles. Among them, the light poles and solar panels and light sources do not need to be considered. Under normal circumstances, even the inferior solar panels can be used for several years (provided that they are produced by regular manufacturers). Even if the light pole is rusted, it can be used for a few years without a problem. Then there is the light source. , No matter how bad the heat dissipation is, it can be used for several years (provided that the manufacturer is regular). For solar street lights, the controller and battery of solar street lights are prone to problems. The controller accounts for a small proportion of the cost of solar street lights, but the role it plays is extensive and comprehensive. If there is a problem, it is usually enough to replace it. The battery is a difficult problem. A good battery can be charged and discharged normally within the specified time of use. If the quality is inferior, it is easy to have problems. If there is electricity, it cannot be discharged or cannot be charged at all. This is an easy problem. . The solution to the above problems is very simple: when configuring solar street lights, the solar panels must be from regular manufacturers, and the solar panels must be configured as large as possible. Secondly, the battery must be large, so that the stored power is more, and the number of deep discharge cycles It is a kind of protection for the battery, which can prolong the life of the solar street light, and the corresponding quality has also been improved.
