Era in the development, the core technology problems be solved step by step, the lithium battery has low cost, large capacity, long service life. Lithium-ion batteries used in led solar street lamps to reduce the cost, increases the storing capacity and prolong the service life, shorten the cycle back to this, for the wide application of led solar street lamps have laid a good industrial base. In some areas, remote set up grid lamp quantity is big, power consumption is big. Rural solar street lamp does not need wiring, because each with a street light on the solar street light photovoltaic panels of independent power generation. Because each led solar street light is independent of the system, even when mudslides and landslides and other geological disasters won't because of a street lamp or a number of street lamp damage and cause all the lights go out. Believe that once led solar street light, the slow development under the lead of new technology, new technology innovation, and constantly move forward, for the comprehensive construction socialism new countryside play an irreplaceable force, perhaps the development of the rural market will have more value.
