How do solar street light will light energy into electrical energy?

Solar street lamps mainly consists of four parts: photovoltaic modules, light emitting diode, solar battery and the controller. Photovoltaic modules to absorb light during the day, convert solar energy into electrical energy storage in solar cells, to discharge lighting when it is dark at night. General

solar street lamp is mainly composed of four parts: the photovoltaic modules, light emitting diode, solar battery and the controller. Photovoltaic modules to absorb light during the day, convert solar energy into electrical energy storage in solar cells, to discharge lighting when it is dark at night. Sunny days commonly, under the ideal light intensity, full of electricity, as long as four hours per charge can guarantee up to five days after the completion of the above, continuous rain 3 days also can work normally. In addition, the LED street lamp, according to different requirements, the controller can be solar street light switch is designed for electric or time control, not only the storage battery charging and discharging time can be controlled, can also control the intensity of discharge size. In short, in the energy consumption is more and more big in the city, the city electricity has not its weight: industrial electric power consumption in recent years, life has been high, rising year by year, many cities peak electricity is more common. If solar street lamps can widely spread, people don't have to worry about affected the normal production and living.
