The special requirements of solar lighting Limited, the company can set up manual switch or remote control switch, remote control distance according to actual requirements, a management staff by remote control, all the lamps go out. For example: playground, dormitory area. Solar cell is essentially a semiconductor device, it is typically characterized by light energy directly into electrical energy. The main function of solar cells convert light energy into electrical energy in residential solar lighting system, this phenomenon is called the photovoltaic effect. Among the more common solar cells, and more practical, there are three single crystal silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells in the sunshine good too sunny eastern and western regions of solar lighting equipment site, the use of polycrystalline silicon solar cells as well, because of polycrystalline silicon solar cell production process is relatively simple, the price is lower than the single crystal. Conversion efficiency in recent years continues to increase. More sunshine in the rainy days are not very abundant relative to southern regions, the use of single crystal silicon solar cells as well, because the electrical properties of silicon solar cells is relatively stable parameters. Of course, in the case of amorphous silicon solar cells sunlight is weak indoors better, because amorphous silicon solar cells on solar illumination conditions require relatively low. Solar lighting manufacturer | Qingdao Yi Gang (certified) | solar lighting provided by Yi Gang, Qingdao Solar Limited.
