Price of solar lamp solar street lamps system of solar battery components

Solar energy battery components ( Solar panels) Is the most important core component of solar street lamps system which convert solar energy into electrical energy during the day to the stored in the storage battery, and output to the street lamp light which the photosource sends out aftertransmits the evening.

solar battery components, Solar panels) Is the core of the solar street light system is the most important parts. It converts solar energy into electrical energy during the day, and sending them to the storage battery. In the evening, it is output to the street lamp light source. Solar energy battery components are affect the solar street light system the most important factor in the quality and cost. What is the traffic lights, because a single solar cells cannot be directly used as power supply, and need to according to the system requirements will be a few individual solar cells in series or in parallel, and tightly encapsulated into the solar cell module. Conventional solar battery components are usually made of crystalline silicon solar cells with high efficiency, super white texture toughened glass, EVA, transparent TPT backplane and aluminum alloy frame. Solar energy battery components according to different materials and the performance of the divided into the following categories: ( 1) Monocrystalline silicon solar cells, and is used in the manufacture of material is single crystal silicon solar cell components, at present the photoelectric conversion efficiency is highest, generally about 17%, up more than 24%. ( 2) Polycrystalline silicon solar cells made from polycrystalline silicon, low cost, the conversion efficiency is slightly lower than that of single crystal silicon, general photoelectric conversion efficiency is about 15%. ( 3) Amorphous silicon solar cell is a kind of thin film solar cells, made of different materials such as ceramic, graphite, and metal as the substrate materials. It has many advantages such as low cost and good weak light. At the same time, because of the short development time, but also has low conversion efficiency and performance is not stable, fast attenuation and other shortcomings. With the continuous development of science and technology, the application of thin film solar modules will be more and more widely. The amorphous silicon panels, thin film solar cells, organic solar cells. In addition, there are many components of composite solar cells and bendable flexible solar module. Because they are not used for solar street light system, so will not covered here.
