Nowadays more and more widely popularization of solar street lights, but not all of the area is fit for the development of solar street lamps, so what is hindered the development of solar street light? One, not only the high cost, limited by natural factors influence too much current
now the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 The popularity of more and more widely, but not all of the area is fit for the development of solar street lamps, so what is hindered the development of solar street light? One, not only cost is high, the restrictions are more affected by the natural factors of the use of solar street lamps and two shortage, it is because of its high cost, to invest big, this is the big problem encountered in the process of promotion of common; Second, solar energy as a kind of natural energy, after all to subject to the conditions of illumination, the weather and other natural factors, which to a certain extent, it restricts the development of solar street light. Second, the light narrow range due to solar street lamps for general illumination range 6 - 7 meters, more than 7 meters will be dark, not suitable for the tunnel, the urban main road these high requirement to the light, at present is mainly suitable for the narrow two-lane road. Three, difficult to achieve economies of scale if familiar to solar power, we will know solar panels 【 Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 Are able to convert the sun's light energy into electrical energy, panels, conversion rate is quite important. At present there are polycrystalline and monocrystalline silicon solar panels 【 Silicon single crystal. 】 Two, the former conversion rate is less than the latter, but win on price. But these enterprises are in foreign raw materials imported for assembly, able to produce domestic enterprises hardly monocrystalline silicon and polycrystalline silicon panels, solar photovoltaic enterprise of domestic general scale is small, difficult to achieve economies of scale.
