With the increasing lack of wholesale solar lights earth's resources, based on investment costs of energy rising Shandong solar lights, safety and pollution problems can be said to be everywhere. Solar energy as an "inexhaustible" security, environmental protection and new energy sources more and more important solar lighting, and with the improvement of technology, cost reduction, has ushered in rapid development, but also the future of a major Renewable energy development. 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. Auxiliary mounting equipment: expansion screws, mounting bracket and buried. A solar lighting, solar lighting, provided by Qingdao Qingdao Yi Gang Yi Gang Solar Limited.
