Types of lithium battery solar street energy storage batteries and anti-theft measures

In the life of the calendar, you will often see Lithium battery solar street light as a lighting tool. However, in appearance, you will not see a battery with energy storage, you can only see the solar panels, but at night, you will use the energy of the energy storage battery to provide power for the street lights to illuminate the road. Therefore, we also need to know the type of energy storage battery and its installation and theft prevention when we understand the solar street light.

Lithium Battery Solar Street Light Solar Photovoltaic Power Generation System is a solar cell made by the principle of photovoltaic effect that directly converts solar energy into electrical energy. Solar cells are the smallest unit used for photoelectric conversion. It measures from about 4 square centimeters to 100 square centimeters. The operating voltage of the solar cell is 0.45 to 0.50 volts, and generally cannot be used alone as a power source. After the tantalum battery cells are connected in series, paralleled and packaged, they become solar cell modules. It has a power range from a few watts to a few hundred watts and can be used as a power source alone. The solar cells are connected in series, paralleled and mounted on the bracket, which constitutes a square array of solar cells. It can output several hundred watts, and the power of kW or more is the power generator of the photovoltaic power station. Commonly used lithium battery solar street light batteries are mainly silicon solar cells. There are currently three commercially available silicon solar cells in the world: monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells.

Lithium battery solar street lamp Monocrystalline silicon solar cell is currently the fastest developed solar cell. Its structure and production process have been shaped, and its products have been widely used in space and ground. This kind of solar cell uses high-purity single crystal silicon rod as raw material, and the purity requirement is 99.999%. In order to reduce production costs, solar cells such as solar cells for ground applications are now using solar-grade single crystal silicon rods, and material performance indicators have been relaxed. Monocrystalline silicon solar cells have the highest manufacturing costs, but the photoelectric conversion efficiency is also the highest, with the highest reaching 24%. At present, polycrystalline silicon materials used in polycrystalline silicon solar cells are mostly aggregates containing a large number of single crystal particles, or melted and cast from waste secondary silicon material and metallurgical grade silicon material, and then injected into a graphite mold to be slowly solidified and cooled. That is, a polycrystalline silicon ingot. The ingot can be cast into cubes for slicing into square solar cells for improved material utilization and ease of assembly. The manufacturing process of polycrystalline silicon solar cells is similar to that of single crystal silicon solar cells, and its photoelectric conversion efficiency is about 12%, which is slightly lower than that of single crystal silicon solar cells, but its material is simple to manufacture, saves power consumption, and the total production cost is low. A lot of development has been made.
