How to maintain solar street lights in winter in northern areas?

Winter in the north often has rain and snow. It is very cold and the sunshine time is short. How to maintain the normal operation of solar street lights in this season? Lithium batteries cannot be used in areas with cold temperatures. Only solar colloidal batteries can be used. What we should pay attention to are the two major components of storage batteries and solar panels.

1. Frequently check the surface of solar panels
Solar panels use the photovoltaic effect to charge the battery. In winter, the sunshine time is short and the light intensity is weak, resulting in low charging efficiency, and the brightness at night is not as strong as in summer. Therefore, we must pay special attention to the use of solar panels. There is a lot of snow in the north in winter, so we must check the surface of solar panels frequently. If it is covered by a thick layer of snow, it will not be able to absorb sunlight to charge the battery. It will cause the light not to light up, and it will also affect the battery life.

2. Maintenance of battery
The ground temperature in the north is cold in winter. If the battery is buried too shallowly, the battery may be frozen. Pay attention to the wiring openings around the valve of the street light pole. The weather is dry and cold. Will cause the battery to short-circuit and burn out.

In short, the maintenance of solar street lights in northern areas requires special care. If the lights are not turned on, the above two situations must be considered first, and then how to solve the problems that occur during the use of solar street lights? , If you still don’t turn on the lights, you can consult the solar street light manufacturers. Finally, I hope that all buyers will buy good quality and choose reliable manufacturers. This is important.
