The simplest principle of solar power generation is what we call a chemical reaction, which converts solar energy into electrical energy. This conversion process is the process by which solar radiation energy photons are converted into electrical energy through semiconductor materials, commonly known as the "photovoltaic effect", and solar cells are made using this effect.
Working principle of solar video surveillance power supply system:
1. When the sunlight is strong, the current generated by the solar photovoltaic modules converges to the controller, which monitors the power supply. Solar photovoltaic modules provide power to video monitoring components through controllers, while storing excess energy in the energy storage system.
2. When the sunlight is weak and the power generation of the solar energy storage unit panel cannot meet the energy requirements of video monitoring, the load not only obtains energy from the solar energy storage unit panel, but also the energy storage system is in a discharge state to ensure stable operation of video monitoring.
3. When the sunlight conditions are poor at night or on cloudy days, the energy storage system will be used to provide power to the video surveillance.
The installation of wireless monitoring systems in the field is severely affected by the remote location where the equipment is installed, the inability to provide power, high power supply costs, and unstable power supply, which seriously affect the application. This situation can be solved by using solar power supply. The working principle of the solar powered wireless video monitoring system is that the solar cell module converts the solar energy into electrical energy. The solar charging and discharging control serves as the central control device, on the one hand, storing the converted electrical energy from the solar cell module in the battery pack, and on the other hand, controlling the battery pack to supply power to the camera, wireless video transmission equipment, and other load devices. If there is an AC device in the electrical equipment, the inverter can convert DC power into AC power to provide power to the AC device.
