Solar street light heart
Nowadays, solar street lamps can be seen on the streets of most cities and rural areas in our country. As a very ideal lighting equipment in modern society, it can be foreseen that it will be more widely used in the future, and it will be used endlessly during the day. The energy produced by the sun's rays brings light to the night and brings convenience to people.
Because solar street lights are environmentally friendly and pollution-free, while saving energy, they are being promoted vigorously in our country. Let's let the solar street light manufacturer-Yangzhou Only Optoelectronics Technology Co., Ltd. interpret for us where the "heart part" of this street light is!
The solar street lamp can work normally, and it must be inseparable from its "heart"-solar panels. Only with it, can the absorbed solar radiation energy be converted into electrical energy that can provide light energy through the corresponding photochemical reaction, etc. It can be seen how important the position of solar panels is, and we want to increase the service life of solar street lights. , The first thing is to improve the technology of manufacturing solar panels.
Generally speaking, the materials used to manufacture solar panels are silicon. The production technology of this kind of raw material is relatively complicated and has a certain impact on the environment. Therefore, only technologically advanced solar street lamp manufacturers can produce silicon that meets the use of solar panels.
According to the classification efficiency of solar panels, it can usually be divided into two types: monocrystalline silicon and polycrystalline silicon. In order to obtain better photoelectric conversion efficiency, it is best to use monocrystalline silicon solar panels, which may be slightly more expensive, but the service life of solar street lights using this panel is much longer than that of ordinary products, and it also saves energy. It is cost-effective in the long run. However, due to cost issues, many new rural construction nowadays use polycrystalline silicon solar panels.
