Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-controlled sealed batteries (gel batteries) store electrical energy, ultra-bright LED lamps are used as light sources, and are controlled by intelligent charge and discharge controllers to replace traditional public power lighting street lights.
As an indispensable part of solar street lights, battery is one of the important parts of solar street lights. What are the characteristics of batteries produced by solar street lamp manufacturers?
1. Relatively good deep cycle capability, with good overcharge and overdischarge capabilities.
2. Long life, special process design and long life battery guaranteed by gel electrolyte.
3. Suitable for different environmental requirements, such as batteries that can be used normally under different conditions such as high altitude, high temperature and low temperature.
Solar batteries are related to the service life of solar street lights. To ensure that its street lights can be used for a long time, the quality of the solar battery must be guaranteed.
With the development and progress of solar photovoltaic technology, it was first applied to lighting fixtures for civilian use. In recent years, solar lighting products have been applied in solar garden lights, solar lawn lights, and solar decorative lights due to the dual advantages of environmental protection and energy saving. Gradually form a scale.
The main function of solar street lamp batteries is to convert light energy into electrical energy. This phenomenon is called photovoltaic effect. Among the many solar cells, there are three kinds of solar cells that are more common and practical: monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells. In the eastern and western regions with sufficient sunlight, it is better to use polycrystalline silicon solar cells. The production process of polycrystalline silicon solar cells is relatively simple, and the price is lower than that of single crystal.
Exchange efficiency has been continuously improved in recent years. In the southern regions where there is a lot of sunlight on cloudy and rainy days, it is better to use monocrystalline silicon solar cells because the electrical performance parameters of monocrystalline silicon solar cells are relatively stable. Of course, amorphous silicon solar cells are better when indoor sunlight is very weak, because amorphous silicon solar cells have relatively low requirements for sunlight conditions.
