Using proprietary technology of solar lighting manufacturers, dedicated microcomputer automatic control system, automatic detection and adjustment charge and discharge control and protection systems. Poles, lighthouse, lamp, after oxidation, anti-corrosion treatment of small solar lighting, environmental adaptability, anti-frost, anti-sun exposure. On rainy days, the sun is relatively more abundant in the southern region is not very, monocrystalline 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 is better indoor sunlight is weak because the amorphous silicon solar cells for solar illumination conditions require relatively low. Solar lights offer _ Qingdao Yi Gang (certified) _ solar lighting is provided by solar energy, Ltd. Qingdao Yi Gang. Qingdao Yi Steel Solar Limited (www.gangyisolar.com) is Qingdao, a leader in solar and renewable energy, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
