1, the installation contrast Installation of solar street lights, no paved the complex line, only a cement base and do a battery pit of 1m galvanized bolt can. The city circuit lamp construction in complex operating procedures. Must first paved cable trenching piping, pipe threading, backfill and other large civil construction, consumes a lot of manpower, material and financial resources. Debug Finally, if there are problems, they cause great consumption. 2, the cost comparison Solar lights an investment, the long-term benefit, simple lines, not to produce maintenance costs, does not produce expensive electricity bills. 6-7 years to recover the cost savings of more than 100 million electricity and maintenance costs after 3-4 years. City circuit lights are expensive electricity tariffs, circuit complexity, requires long-term uninterrupted line overhaul. Particularly unstable voltage sodium lamp perishable inevitable With the extension of the useful life, the aging, the maintenance cost is increasing year by year. 3, the safety of contrast Solar street light is 12-24V low voltage, voltage stability, reliable operation, there is no security risk, ecological communities, the Highways department ideal product. City circuit lamp safety hazards, people's living environment, road reconstruction, landscape engineering, construction, power supply is not normal, in the case of changing cross water gas pipeline construction and other aspects to bring a lot of hidden dangers.

Solar power supply system, the performance of the battery is good or bad is a direct impact on the overall costs of the system and run good or bad, and the life of the program, the selection of the company with the Institute of Metal Research, Chinese Academy of Sciences jointly developed the latest achievements in energy storage gel batteries, Ji Guangguang electric Compared with ordinary lead-acid battery, it is in the design and manufacturing process has the following salient features: long service life, under normal circumstances, the service life of five to ten years. Use appropriate ratio of negative alloy recipe and active substances, the battery for energy storage battery cycle charge and discharge characteristics. The design of the gel electrolyte, and effective inhibition of sulfation phenomenon of the active material off the rust and plate, thereby delaying the performance of the battery during use will decline. Greatly improved battery deep charge-discharge cycle life. Selection of sleeping mat four generations of lighting products LED light source.
