Does the solar street light need an external power supply?

   In the past, the street lights we used needed to be connected to a power source to work normally, and the installation was complicated, which consumed manpower, material and financial resources. At this moment, Jiangsu Naite Lighting Electric Co., Ltd. is a manufacturer engaged in the production and design of solar street lamps and high-pole lamps. With 20 years of experience in the production of solar street lamps, it has created the most professional solar street lamp manufacturer. Contact number: 13805257308. , The presentation of solar street lights has solved some of the shortcomings of street lights in the past. It has the advantages of environmental protection, energy saving, and high efficiency. Then, some people may have a doubt, that is, do solar street lights need an external power supply? The technical staff of Jiangsu Naite Lighting Electric Co., Ltd. answered the master:

   Solar street light is a new type of energy-saving and environmentally friendly product. It is mainly converted into electrical energy by absorbing sunlight and stored in the battery. The battery supplies power to the light source. Therefore, it does not require an external power source. Solar street light system It is an independent power generation system.

The transformation principle of    solar street lights:

   In daylight, solar cell modules generate an inevitable electromotive force under light conditions, and the solar cell array is formed through series and parallel connection of the modules, so that the voltage of the array can meet the requirements of the input voltage of the system. Then charge the battery through the charge and discharge controller, and store the electric energy converted from light energy. At night, the battery pack supplies input power to the inverter. Through the induction of the inverter, the direct current is converted into alternating current, which is sent to the power distribution cabinet, and the power is supplied by the switching function of the power distribution cabinet. The discharge environment of the battery pack is controlled by the controller to ensure the normal use of the battery.

   Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-regulated sealed batteries (gel batteries) store electrical energy, no need to lay cables, no AC power supply, no electricity bills; DC power supply, control; with good invariability , Long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical advantages.

   The above is the explanation about the need for an external power supply for solar street lights. Solar street lights use solar photovoltaic cells to supply electricity. Solar energy is a green and environmentally friendly new energy source, 'inexhaustible and inexhaustible.' Enriching the operation of solar energy resources is of positive significance to alleviating the tight environment of conventional energy.
