How to quickly find out the new solar street lights street lamp failure reason

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, but if failed solar street lamps, such as lamps and lanterns lighting lamps and lanterns of a shorter time



the operation of the solar street light is relatively simple, is a process of charging and discharging, solar panels during the day' 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. 】 Power battery to power a lamp in the evening, circulating the process every day, but if failed solar street lamps, such as lamps and lanterns lighting time shorter lamps and lanterns is not bright, how can we quickly find out the reason? First of all need to know the lamps and lanterns 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 area along the river bank is ordinary, 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. 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 also normal. Then we can consider to change a new controller, after the replacement of 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, less than 10 v, so we need to check panel wire is good, if there is a connection are intact, but or low voltage panels, this could be the panels, but appear such circumstance is very few, mostly is concentrated on the battery. Battery voltage is lower than 10 v, generally this is the preferred controller problems, leading to loss of battery discharge power and cannot 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 we must first consider if the lamps and lanterns dawn in controller, if it is found that lamps and lanterns long light so we don't recommend replacing battery ( Long time not bright, storage battery must be damaged) 。 Recommended reading: windy influential for solar street light
