What is a solar light?

The principle of solar light system: the working principle of the system is simple, the solar cell made by the photovoltaic system uses solar cells to receive solar radiation and convert it into electric energy output. The charging and discharging point controller is often in the battery, and the illumination is gradually reduced at night. Up to 101ux, the solar panel open circuit voltage is about 4.5v, the charge and discharge controller detects this voltage value and then the battery is discharged. After the battery discharges 8 jokes, the charge controller operates and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery. Working principle: During the daytime, under the illumination condition, the solar cell module generates a certain electromotive force, and the solar cell array is formed by series connection of the components, so that the square matrix voltage reaches the requirement of the system input voltage. The battery is charged by the charge and discharge controller, and the electric energy converted by the light energy is stored. In the evening, the battery pack provides input power to the inverter. Through the action of the inverter, the DC power is converted into AC power, which is sent to the power distribution cabinet, and is powered 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 should also be equipped with a limited load protection box lightning protection device to protect the system equipment from overload operation and lightning strikes, and to maintain the safe use of system equipment. The advantages of solar lamps: the use of solar photovoltaic cells to provide electricity, solar energy as a new source of green and white energy, full solar energy resources have a positive significance to alleviate the situation of conventional energy shortages. The installation of solar lights is simple and convenient. It does not need to do a lot of basic engineering such as laying cables for ordinary street lamps. Only one base is needed, and all the lines and control parts are square boxes in the lamp holder to form a whole. The operation and maintenance cost of solar street lamps is low. The solar power supply used by solar street lights, except for the conversion of rainy days into pilot power supply wires, generates a small portion of the electricity cost, and the operating cost is almost zero. The entire system is automatically controlled, requiring no human intervention and virtually no maintenance costs.
