The reasons of solar street light does not light

Solar energy is an important energy source around us. Through solar energy, we have invented solar water heaters and solar street lights. After installation, if it is found that the solar street light does not light, it is necessary to find out the reason and solve the problem according to the reason.

A: solar street light does not light reasons:

1.the solar street light can shine, mainly because there is a battery, and there are three types of battery, one is lead-acid battery, its service life is only about two years. Colloidal batteries have a long service life of about three years. At present, many solar street lights use lithium batteries, with the longest service life of about 6 years. If the lead-acid battery is chosen, it may be damaged after one or two years, making the lighting time of street lights shorter and failure to light up.

2. It is also possible that the controller of the solar street light is damaged, after wind, rain, lightning or other reasons, leading to the normal operation of the controller.

3. It is also possible that the light source of the light cap is damaged. If it is not artificially damaged, it may be the battery damage or other natural reasons that lead to the normal operation of the solar street light, which is not bright or flashing.

4. the last reason is the aging of the line, this phenomenon is also more common, the aging of the line is disconnected, and the solar street light can not work normally.

Two: solution

1.the best choice of installed solar street light battery is lithium battery, long service life, installation also need to pay attention to the voltage and capacity of the battery to match, at the same time after the installation also need to be debugged, can be used normally.

2. If the controller is damaged, remove the original controller, select a matching controller of the same model, and debug it.

3. if it is because of the damage of the solar lamp source, it can only be replaced, the welding should be firm, and attention should be paid to the maintenance of the line.

Solar street light has become an essential item of The Times, which brings light and beauty to the residents.
