Causes of Premature Failure of Solar Street Lights Off Grid Solar Power Systems

Description:

After the solar street light is generally installed, the time for replacing the battery for the first time is 5 to 7 years after installation. Before this, the solar street light can be used and operated normally, because other components except the battery have a service life. They are very long, the life of solar panels is generally 20 to 25 years, the LED usage time is 15-20 years, and the controller life is 8-10 years.

If the solar street light is damaged before the initial replacement of the battery, it is caused by the following reasons:

1. The configuration is not reasonable

Unreasonable configuration will cause the solar street light to be charged normally every day. The battery will be overloaded for a long time, which will shorten the service life of the battery. We suggest that when configuring the battery capacity, there should be more than 20% of the balance. The battery plays a very good role in protection.

2. The installation method is wrong

Some solar street lights are very reasonable in configuration, and the quality of each component of the product is also very good. However, because the installation method is not correct, the battery can not be charged properly. Common installation errors are:

(1). The installation angle of the solar panel is wrong.

For China, the installation direction of solar panels is generally about 15 degrees west of the south, and different areas need to be adjusted accordingly.

(2). Blocking of buildings and trees

Solar street lights are installed in buildings and trees that block sunlight, causing solar street lights to fail to charge properly.

(3). The solar panel is covered

Some construction sites and contaminated areas are dusty, or have many leaves, or heavy snow. After the solar panels are covered, it is difficult to recharge, causing long-term loss of electricity, thus reducing the life of solar street lamps.

Solar street lamps are expensive. When installing solar street lamps, we should install them according to requirements. We should also maintain them regularly in order to ensure that solar street lamps can work normally.
