The role of each part of the solar street light

(1) Solar cell modules: Solar cell modules are the central part of the Solar street lamp system, and they are also the most valuable part of the Solar street lamp system. Its function is to convert the sun’s radiant energy into electric energy, or send it to the storage battery for storage, or to promote the work of the load. The quality and cost of solar cell modules will directly determine the quality and cost of the street lamp system.

(2) Solar controller: The function of the solar controller is to control the working condition of the street lamp, and play the role of over-charge protection and over-discharge protection for the battery. In places with large temperature differences, a qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch and time control switch should be optional options of the controller.

(3) Batteries: generally lead-acid batteries, in small and micro systems, nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries can also be used. Its function is to store the electric energy supplied by the solar cell module when there is light, and then release it when needed.

(4) Lamps and light sources: The lamps protect the light source equipment from the sun and rain from the outside, and can also gather the light source and reflected light; the light source is mainly used for luminous lighting, generally divided into several types: electronic energy saving Lamps, LED lamps, low-pressure sodium lamps and induction lamps (LVD); among them, induction lamps have good energy-saving efficiency and are bright (compared with equivalent power).
