What is the reason why the solar street lamp does not turn on when it rains, and how to solve it

Many customers buy solar street lights against their original intentions and can't stand the temptation of low prices. They choose low-priced products. This will cause the solar street lights to not turn on when it rains. So what causes it?

We all know that the solar lamp absorbs light energy during the day and converts it into electrical energy and stores it in the battery. At night, it supplies power to the light source to achieve the lighting effect. If it does not turn on when it rains, it is because the battery has no electricity. Under what circumstances will cause the battery to appear dead?

1. The power of solar panel is too small

The low power of the battery panel leads to a slow charging speed. Often it can only be charged about half after a day of charging. Therefore, the battery’s storage capacity is small and can only be used for one night. If the next day is cloudy and rainy, it will be Doesn't light up.

2. The battery has a small capacity

The capacity of the battery is small, and the wattage of the light source is constant, so the total lighting time must be small. Often it can only be used for one night, and the stored power in the battery is gone. If it rains and there is no sunlight the next day, Naturally, the lights cannot be turned on at night.

3. The solar panels are blocked

If the solar panel is obscured by surrounding things, even a small part of it will seriously affect the charging efficiency of the solar panel, the charging efficiency will drop, and the amount of electricity stored in the battery will naturally be less.

In general, the reason why solar street lights do not turn on when it rains is because of the low configuration of solar lights and the solar panels being blocked by surrounding things. The solution we can solve is to choose a regular solar street lamp manufacturer to replace a higher-power battery panel or a larger capacity battery, and always check whether there is something around the solar street lamp that blocks the solar panel.
