The basic principle of solar battery

The basic principles of the solar battery photovoltaic power generation system are the same, so the design ideas of solar street lights can also be based on the general solar power generation system. First determine the power of the light source, the daily working time, and ensure a few cloudy and rainy days, and then calculate the battery capacity and solar battery components. Power. However, solar street lights have their particularities and need to ensure the stability and reliability of the system, so special attention should be paid when designing. Solar street lights use the photovoltaic effect principle of solar batteries. During the day, the solar batteries absorb solar photon energy to generate electricity, which is stored in the battery through the controller. When night falls or the light around the lamp is low, the battery supplies power to the light source through the controller until it is set. Cut off after a set time.   The working time of solar street lights every night is the core parameter that determines the size of the components in the solar street light system. By determining the working time, the daily power consumption of the load and the corresponding charging current of the solar battery components can be calculated preliminarily. The number of consecutive cloudy and rainy days that the solar street light needs to maintain. This parameter determines the size of the battery capacity and the solar cell module power required to restore the battery capacity after the cloudy and rainy days. With the continuous improvement of solar cell conversion efficiency and production technology, the application of solar battery photovoltaic power generation has become more and more extensive. In the field of lighting, solar street lamps are the main application mode of photovoltaic power generation systems in China. Recognize and accept.
