Hunan rural solar street light

Solar energy battery components generally choose monocrystalline silicon or polycrystalline silicon solar cell components; High power LED light source is generally selected LED lamp holder; Controller is usually placed in a light pole, relating to, the control, overcharge, discharge protection and reverse connect protection, more advanced control

solar battery components usually use monocrystalline silicon or polycrystalline silicon solar cell components; High power led light source are normally used for light emitting diode lamp holder. Controller is usually placed on the light pole, light control, time control, over charge and over discharge protection and reverse connection protection. The superior controller adjust the lighting time, half power, intelligent charge and discharge, etc. Battery in general on the ground, otherwise there will be a special battery insulation box. Can use a colloid battery, iron and aluminum battery or lithium battery. Solar street lamps to run automatically, no need for trenching and wiring, but need to install the light pole in the embedded part ( Concrete base) On. Photovoltaic solar panels is solar panels, photovoltaic panels is a professional term, solar panels is our solar power. Photovoltaic panels is one of the types of solar panels, it USES electronic semiconductor materials under the light from within, and generate an empty hole of the current. Solar panels, solar photovoltaic power generation system consists of several kinds of methods, is composed of solar battery, solar controller and battery. If the output power to 220 v or 110 v ac, also need a inverter. The role of each part is: ( 1) Solar panel: solar panel is the core part of solar power generation system, also is the most valuable part of the solar system. Its function is to convert the sun's radiation ability into electrical energy, or store it into the battery, or promote work load. Quality and cost of solar panels will directly determine the quality and cost of the whole system. ( 2) Solar controller: solar controller's function is to control the working state of the whole solar street light system, to prevent the battery charge and discharge. In difference in temperature big place, qualified controller should also has temperature compensation function. Other additional features, such as light control and time control switch should be the optional features of the controller. ( 3) Battery: normally lead-acid battery, nickel metal hydride batteries, nickel-cadmium batteries or lithium batteries can also be used for small and micro system. Its function is when there is light store electric energy from solar panels, and released when needed. ( 4) Inverter: in many cases, the need to provide 220 v alternating current (ac) and 110 v alternating current. Due to the direct output of solar energy is commonly 12 VDC and 24 VDC and 48 VDC. To 220 volts ac power supply, need to convert solar power generation system to produce direct current (DC) to alternating current (ac), so you need to use DC ac inverter. In some cases, when need different voltage of load, DC - is needed DC inverter, such as 24 v DC power is converted into a 5 v DC power supply ( Note that this is not a simple step-down) 。 According to the solar street lamps lighting control point lights have some irrationality. In many cases, users need to turn on the light, before the light completely dark and light can't completely below lighting control points, this is the traditional solar street light can't do it. The advantages of above is for solar electromagnetic plate is introduced. I hope you can understand. Hebei solar led street light
