The operation of the solar street light is relatively simple, it is a process of charging and discharging, solar panels power battery to power a lamp at night during the day, every day cycle this process, if failed solar street lamps, such as lamps and lanterns lighting time shorter lamps and lanterns is not bright, how do we find out the reason?
the first thing you need to know the lamps and lanterns of lighting time is short or not bright, if time is short of lamps and lanterns lighting configuration problems or panels generating capacity is not enough, the reason may be configured not reasonable configuration is small, it is possible that the panels attached above a thick layer of dust, the situation in the riverside region is more common, lamps and lanterns of lighting in the winter time is short, continuous cloudy days are short, out clean scrubbed the battery of this kind of circumstance, according to the degree of adhesion often do it; The second is not bright, not bright lights more concentrated in the condition of the controller is broken or the battery is broken, broken led lamp holder is less, the damage to the panels also is less, if the problem is the controller, screening method is we use a voltmeter to measure the voltage and battery voltage panels, if there is a sun in the daytime of panels more than 12 v voltage panels, there is no problem, if the battery voltage is explained in more than 10 v battery is normal, then we can consider to change a new controller to see, to change after the lamps and lanterns is explained in the 1 to 2 natural lighting in the future is the problem of controller, general panels and the battery is normal without light is small, if we measured the voltage of the panels during the day lower than 10 v, so we need to check panel wire is good, if there is a connection is in good condition, but or low voltage panels, this could be the panels, but appear such circumstance is very few, most has focused on the battery, the battery voltage is lower than 10 v, generally it is the first choice is the controller battery discharge problem that caused loss of electricity and not charge in time, the second is the battery quality, the use of long time lead to too much resistance, already can't normal charge and discharge.
in short if the lamps and lanterns is not bright we preferred drug in controller, if found that for a long period of time of lamps and lanterns light so we don't recommend replacing battery ( Long time not bright, storage battery must be damaged) 。
