On rainy days the sun is relatively more abundant in the southern region is not very solar lighting company, monocrystalline silicon solar cells as well solar lighting manufacturers, silicon solar cells due to relatively stable electrical performance 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. Using proprietary technology of solar lighting, special microcomputer control system, automatically detect and adjust the charge and discharge control and protection systems. The working principle is solar lighting sales, when the sun light shines silicon solar panels, photo-generated electron - hole pairs in the battery built-in electrostatic field next, since the electron hole with different charge points are separated on both sides of the formation of 'the photovoltaic', that 'the photovoltaic effect'. Solar lighting company, Qingdao Yi Gang (online consultation), 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. Qingdao Yi Gang leader with the staff warmly welcome all inquiries negotiations to create Qingdao Yi Gang better future.
