Solar lamps on and off 1. Solar lighting with automatic on and off function, the night comes (5:30 in winter, summer 7:30) solar lights offer, solar lights automatically light up, the morning solar lamps turn off automatically, without personnel management and maintenance. 2. My company does not manufacture the solar lighting solar lighting manufacturers photosensor, complete elimination of daytime lights problem leaves, dust, etc. caused. 3. special requirements, companies can set up manual switch or remote control switch, remote control distance of a remote control, all the lights are off in accordance with the actual requirements of production and management personnel. For example: playground, dormitory area. The main function of solar cells convert light energy into electrical energy in a solar lighting, this phenomenon is known as 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, the use of polycrystalline silicon solar cells as well solar lighting Light price, because 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. Choose high-capacity battery dedicated maintenance, service life of 5 - 12 years. Solar lights, Qingdao Yi Gang (certified), solar lighting is provided by solar energy Ltd. Qingdao Yi Gang. Yi Gang Qingdao Solar Limited (www.gangyisolar.com) is in Qingdao, Shandong, solar and renewable energy leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
