Choose high-capacity battery dedicated maintenance, life of more than 5-12 years. Auxiliary mounting equipment: expansion screws, mounting bracket and buried. About Solar lighting applications Comparison: Comparison of a mains lighting installation complexity: in the city lighting project has a complex operating procedures, first laying of cables, cable trench excavation will be carried out here, and the laying of underground pipe, pipe threading, backfill and other large infrastructure projects. Then lengthy installation, such as a problem with any one line of mobile solar lights, they have a large area of ??rework. And the terrain and lines require complex, high cost of labor and auxiliary materials. Solar lighting installation is simple: When installing solar lamps, without laying a complex line, just do a cement base, and then use stainless steel screws. Like trees in general, save a lot of manpower and material resources. Comparing two high electricity mains lighting: mains lighting work with a fixed high tariffs, to long uninterrupted lines and other configurations for maintenance or replacement, and maintenance costs annually. Shandong tariff-free solar lighting solar lights, and solar panels can guarantee more than 15 years of life. Comparison of three mains lighting a security risk: mains lighting due to the transformation of the construction quality, landscape engineering, materials aging, power supply is not normal, bring a lot of security risks, such as water, electricity and conflict pipeline. Solar lighting is no security risk: solar lighting is ultra low voltage products, safe and reliable operation. Other advantages of solar lighting: Green small solar lights, energy for government office space, noble ecological community continue to reduce property management costs, reduce the cost of overall spending. In summary comparison of the safety of non-solar lighting problems, no consumption of energy-saving, environmental protection, ease of installation, maintenance inherent characteristics such as automatic control will directly bring obvious advantages available construction real estate sales, municipal engineering. Contrast four ordinary lamps light will release carbon dioxide, sulfur dioxide, nitrogen oxides and other harmful gases. Solar Lighting LED light does not release harmful gases, is the green light in the true sense. Small solar lights, solar lighting, provided by Qingdao Qingdao Steel Yi Yi Gang Solar Limited.
