4,such as the installation of solarpanels in the pole,it is necessary to consider the overall wind strength,investmentwill be slightly higher than the ordinary lamp.Device selection and composition of solarenergyIn the design of solar lighting,solar cell components,battery,charge anddischarge controller,light source and other links,any of which will cause the problemof product defects.A solar lamp comprises a solar battery component and a bracket,storage battery,charge and discharge controller,light source,lamps pole,cable andconnecting and fastening auxiliary parts six basic components.One,solar cellSolar cellsuse photovoltaic effect to convert solar energy into electrical energy.For siliconbattery,in standard conditions(spectral irradiance:100W/m 2,spectrum:AM1.5,temperature:25),its open circuit voltage of 0.48~0.6V.will be more than one singlesolar cell connection,and can be a different area,different power solar cellcomponents,can also be referred to as solar panels.Solar cells in the sun,the sun isproportional to the logarithm of the sun,with a negative temperature coefficient,thetemperature rise once,the voltage drop 2mV~3mV.Single crystal silicon solar cells,polycrystalline silicon solar cells,amorphous silicon solar cells are currently morecommon,more practical three kinds of solar cells.Polysilicon solar cell productionprocess is relatively simple,the price is lower than the single crystal silicon.Inrecent years,due to the continuous progress of polysilicon solar cell technology,itsconversion efficiency has been improved.At present,there are two kinds of solar batterypackaging mainly lamination process and epoxy technology.Solar cell using laminationprocess package can guarantee more than 25 years of working life,the technologycharacteristics and the use of life is superior to that of the epoxy packaging form.Solar lighting products introductionsolar cell in essence is a semiconductordevice,its typical characteristics is the direct conversion of light energy intoelectrical energy.Its working principle is,when sunlight shines onto the siliconpanels,resulting in photoinduced electron-hole,in a battery built electrostaticfield,due to electron hole points with different charge separated on both sides to forma"photovoltage",namely"photovoltaic effect".If the built-in electric field on bothsides leads to the electrodes and connected to the load,the load will produce"current",so that the sun light is converted into electrical energy.in fact,batterysunshine is to convert light energy into electrical energy.Therefore,even if thecloudy days can work.
