This paper analyzes the common faults and ordinary street lamp solar street lamps

Solar street light failure? The operation of the solar street light is very simple, mainly through the solar panels generate electricity during the day, evening again by the battery to power a lamp holder, the daily cycle of this process, if failed solar street lamps, such as: lamps and lanterns lighting

if the solar street light is broken? Solar street lamps operation is very simple. It mainly electricity generation by using solar panels during the day, and then use the battery for lamp holder power supply in the evening. Every day in the process cycle. If malfunction solar street lamps, such as lamp lit a shorter time, the light not bright, what shall we do? How to deal with it?

1。 How long does it take to solar street lighting?

if the time is short, lighting the lamp configuration has a problem, or panels of electricity shortage. Reason may be that the unreasonable configuration is relatively small, or attached to a thick layer of dust on panels. Lamps and lanterns lit for a while in the winter. In this case, just put the panels to wipe clean. ？

2。 Look at the solar street light off?

light is not on the main reason is that the controller is broken or had a bad battery, solar energy lamp cap damage are relatively small, relatively small panels damage. If the controller has a problem. ？

investigation method: first measured with voltmeter solar street light plate voltage and battery voltage. If there is a sun in the daytime, the panel voltage is higher than 12 v, then the panel, there is no problem. If the battery voltage is higher than 10 v, the battery showed normal is normal. Then we can consider to change a new controller, take a look at it. After replace the lamp, the problem of the controller is whether the lamp in one or two days of nature was clear location.

usually, panels and the situation of the battery is usually not bright is relatively small. If we measure the voltage less than 10 v, panels during the day, so we need to check whether panels of wire connection is good. If the line is in good condition, the panel voltage is still low, it may be defective panels. However, this is very rare.

all in all, if not bright solar street lamps, we should first consider replace the controller. If you don't bright lights for a long time, we recommend replacing battery ( If you don't bright lights for a long time, the battery will be damaged) 。
