1. Street light engineering installation and operating procedures of chaos, need laying cable. A large number of foundation engineering, such as cable trench excavation, pipe laying, wear tube, backfilling, etc. Is needed. In addition, the device will be debugging for a long time. Terrain and routes will be chaos, Labour and auxiliary material cost will be high. 2. Electricity price is very high. Lines and other configuration should be long-term protection or replace, without interruption, protecting fees should be increased year by year. 3. Unsafe, because in construction, landscape engineering, abnormal material aging, power supply, water and electricity pipes conflict, as well as many potential safety hazard. 4. The unification of the commercial street lamp life of about 10000 hours, the longer service life, the aging condition of pipeline. 5. The size, the greater the commercial street lamp equipment related cost is higher, its total investment will be higher than the solar street light. In addition, unable to estimate the stolen cable loss every year. Solar street lamps 1 simple traffic light. The equipment is simple, do not need to laying messy lines. It just needs a cement base, and stainless steel screws. 2. No electricity, solar street light is a one-time investment, no protection fee, 1 - Three years back your investment, long-term benefit. 3. There is no safe hidden trouble. Solar energy lamp is a kind of safe and reliable operation of low voltage products. 4. The main components of solar street lamps; Ndash solar panels, service life is 25 years. High brightness leds even life over 50000 hours. The service life of solar cell for 5 - 12 years. 5. Green environmental protection, for the development and promotion of noble ecological community to add a new selling point; Can continue to reduce the cost of property management, reduce the public to share the cost of owner.
