This is known as the urban heat island effect.In order to prevent the heat island effect is generally the solar battery obliquely placed,so that the leaves are not attached to,at the same time Solar cell components are installed on the battery charge and discharge control regardless of the size of solar lamps,a good performance of charging and discharging control circuit is essential.To extend the service life of the battery,it is necessary to limit the charge and discharge conditions,to prevent the battery charging and deep discharge,in addition,due to solar photo voltaic power generation system in the control of battery charging more complicated.Failure and success,without a good performance of the charging and discharging control circuit,it is impossible to have a good performance of solar lamps.3.1 anti reverse charge control to prevent the anti charging function,generally is in the solar loop series a diode,diode to prevent reverse charge,the diode should be is a Schottky diode,Schottky diode drop B iP through diode is low.In addition,field effect transistor control to prevent the anti charging function,the pipe pressure drop is lower than that of Schottky diode,just control circuit to be more complex than the front.3.2 anti over charging control to prevent over charging Function,can be connected in series or parallel with a discharge transistor,voltage differential circuit control transistor switch,the excess solar energy through the transistor discharge,ensure that no high voltage to battery charging.The key is to prevent over charging voltage,single lead acid battery for 2.2V.3.3 in addition to the Ni-Cd battery,the battery has a battery of permanent damage.Discharge,so the discharge voltage is not too low.3.4 temperature compensation,battery voltage control point is with the ambient temperature and change,so the solar system should have a temperature controlled reference voltage.
