A brief description of the off-grid solar power generation system and the principle of solar street light-litersol

The off-grid solar power generation system uses solar panels to convert solar energy into electrical energy in the presence of light, supplies power to the load through the solar charge and discharge controller, and charges the battery at the same time; in cloudy weather or no light, through the solar charge and discharge control The inverter supplies power to the DC load from the battery pack, and the battery also directly supplies power to the independent inverter, which is converted into AC power through the independent inverter to supply power to the AC load. System Overview Off-grid solar power generation systems are widely used in remote mountainous areas, non-electric areas, islands, communication base stations and other applications. The system is generally composed of photovoltaic arrays composed of solar cell components, solar charge and discharge controllers, battery packs, off-grid inverters, DC loads and AC loads. The photovoltaic array converts solar energy into electric energy under the condition of illumination, supplies power to the load through the solar charge and discharge controller, and charges the battery pack at the same time; when there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller, At the same time, the battery also directly supplies power to the independent inverter, which is converted into alternating current through the independent inverter, and supplies power to the alternating current load. Under the action, holes flow from the n region to the p region, and electrons flow from the p region to the n region, and a current is formed after the circuit is turned on. This is how photoelectric effect solar cells work. Solar power generation There are two ways of solar power generation, one is the light-heat-electric conversion method, and the other is the light-electric direct conversion method. (1) The light-heat-electric conversion method generates electricity by utilizing the thermal energy generated by solar radiation. Generally, the solar collector converts the absorbed thermal energy into the steam of the working medium, and then drives the steam turbine to generate electricity. The former process is a light-thermal conversion process; the latter process is a thermal-electrical conversion process. (2) Light-to-electricity direct conversion method This method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for light-to-electricity conversion is solar cells. A solar cell is a device that directly converts sunlight energy into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode will convert the sun's light energy into electrical energy and generate electricity. current. When many cells are connected in series or in parallel, it can become a solar cell array with relatively large output power.
