System principle: The system works in a simple way. The solar cell made by using the photovoltaic effect principle receives solar radiation energy and converts it into electricity output. It is stored in the battery through the charge and discharge controller, and it gradually decreases to 10 lux at night. Left and right, Solar Panel open circuit voltage is about 4.5V, charge and discharge controller detects this voltage value after the action, the battery discharges to the lamp. After the battery was discharged for 8 hours, the charge-discharge controller was actuated and the discharge of the battery was completed. The main function of the charge and discharge controller is to protect the battery.
Solar Power System working principle:
During the daytime, under the light conditions, the solar cell module generates a certain electromotive force, and forms a solar cell square array through the series and parallel connection of the components, so that the square matrix voltage reaches the system input voltage requirement. Then the battery is charged by the charge and discharge controller, and the electrical energy converted by the light energy is stored. At night, the battery pack provides input power to the inverter. Through the role of the inverter, the DC power is converted into AC power and transmitted to the power distribution cabinet. The power is supplied by the switching function of the power distribution cabinet. The discharge condition of the battery pack is controlled by the controller to ensure the normal use of the battery. The photovoltaic power station system shall also be equipped with limited-load protection and lightning protection devices to protect the system equipment from overloaded operation and from lightning strikes, and to maintain the safe use of system equipment.
The advantages of solar street lights:
1. Solar street lights use solar photovoltaic cells to provide electricity. Solar energy, as a green and new energy source, is inexhaustible and inexhaustible. Making full use of solar energy resources is of positive significance to ease the tension of conventional energy sources.
2. The installation of solar street lights is simple and convenient. There is no need to do a large number of basic projects such as laying cables as with ordinary street lights. It only requires one base to be fixed, and all the lines and control parts are placed in the lighthouse to form a whole.
3, solar Street Lamp operation and maintenance costs are low. The solar energy used by solar street lamps, except for the small part of the cost of electricity generated when converted into electricity for rainy days, is almost zero. The entire system is operated automatically, without human intervention, and almost no maintenance costs.
