After the 531 new deal, the market of household photovoltaic has basically stagnated, and many dealers have started the solar street lamp business. According to reports, now this business is particularly popular in rural areas.
For the better construction of the city, the street lamps in the city are generally changed to solar street lamps. The price of solar street lamps is reasonable. The procedures for the installation of the traditional street lamps used in the past are complex, and the circuit should be laid, etc., and the power consumption is relatively high, and the street lamp caps with large wattage should be used, which not only makes the lights dim, but also is not conducive to the illumination of the city.
The price of solar street lamp is relatively low, energy-saving and environmental protection, and the installation procedures are simpler than the traditional ones. At the same time, there is no need to lay a very complex circuit. The solar price consists of four parts: LED lamp at the lamp head, lamp pole, battery plate and the controller of solar energy street lamp.
Under the control of the intelligent controller, the solar street lamp in the daytime is illuminated by the sunlight, which absorbs the sunlight and converts it into electric energy. The solar cell module charges the lithium battery in the daytime, and the lithium battery provides power to the LED lamp source in the evening to realize the lighting function. The DC controller can ensure that the lithium battery will not be damaged due to overcharge or overdischarge, and has PIR human body induction, light control, time control, temperature compensation, lightning protection, reverse polarity protection and other functions.
