However, there may be some misunderstandings during the installation of solar panel street lights. The wrong way to install solar street lights will reduce the lighting time and life of solar lights.

ADNLITE solar street light manufacturer wants to let you learn the details that need to be paid attention to during the installation of solar lights through this article. In addition, we will also introduce the installation process of split solar street lights and integrated solar street lights.

7 Mistakes of Solar Street Lights Installation

The 7 incorrect installation methods for solar street lights that our customers have informed us about are listed below:

1. Incorrect Installation Location Selection

The installation location of solar panel street lights is very important. Installing in the shadow of high walls or trees, or being blocked by buildings, fences and other objects will affect the charging effect of solar panels. Even a small shadow on a solar panel can cause a large drop in power across the solar panel. The chips of a solar panel are usually arranged in multiple strings. If a darker shade falls on one cell in the string, the entire string of solar chips will not work. If the solar panels are stringed together, the entire solar panel will not generate electricity. Therefore, the correct choice of installation location is the key to ensure the normal operation of street solar lights.

2. There is Another Light Source

Another situation is that there is another light source next to the solar panel. In this case, the charging voltage of the solar panel will be higher than the voltage controlling the lights. This will prevent the LED from lighting up. For example, there are other street lights next to the solar street lights. Turning on the street lights caused the solar panels to detect the light source, misjudging it as daytime. At this point, the controller will turn off the LED.

3. Irrespective of Lighting Conditions

Solar panel street lights need sufficient sunlight to charge and provide lighting. If there is not enough direct sunlight or is often shaded, the performance of solar street lights will be affected. Therefore, lighting conditions should be carefully evaluated prior to installation.

4. Incorrect Installation Angle

Incorrect installation angle of the solar panel will lead to inefficient charging of the solar panel. Correct angle adjustment of solar panels follows a simple principle. Allow direct sunlight to hit the solar panels to maximize charging efficiency. In various locations, the tilt angle of the solar panels can be referenced to the local latitude. Latitude is the degree to which the solar panel is tilted horizontally. Therefore, it is crucial to adjust the angle of the solar panels for different latitudes and road surfaces.

5. Ignoring Battery Capacity And Quality

Batteries are an important part of storing solar energy. Some installers may opt for lower quality or insufficient capacity batteries to keep costs down. However, this can result in insufficient lighting hours at night or shortened battery life. High-quality batteries with suitable capacity should be selected to ensure the reliability and performance of street solar lights.

6. Cable Too Long

Considering the shading problem of the installation site, there needs to be a long distance between the solar panel and the lamp. Some people will separate the solar panel and lights by 10 meters or more. Then buy two-core random wire from the market to connect the solar panel and the light. If the connected wires are too thin and too long, considerable energy will be lost. This reduces the charging efficiency of the whole solar light.

7. Lack of Proper Maintenance Plan

Solar powered street lights require regular maintenance. This includes cleaning solar panels, checking battery status, cleaning light fixtures, and more. Some installers may neglect a maintenance schedule resulting in degraded or damaged equipment. Regular maintenance is the key to ensure the long-term effective operation of solar street lights.

Install The Battery Box

Mount the battery box on the pole or nearby structure. Ensure that it is securely fixed and protected from moisture and dust. Connect the battery to the system according to the manufacturer’s guidelines.

Set Up The Controller

Considering the shading problem of the installation site, there needs to be a long distance between the solar panel and the lamp. Some people will separate the solar panel and lights by 10 meters or more. Then buy two-core random wire from the market to connect the solar panel and the light. If the connected wires are too thin and too long, considerable energy will be lost. This reduces the charging efficiency of the whole solar light.

Test The System

Before finalizing the installation, thoroughly test the solar street light system. Verify that all connections are functioning correctly. Including the charging, battery storage, and lighting. Adjust any settings or connections as necessary.

Secure The Light Fixture

Attach the LED light fixture to the top of the pole securely. Ensure it is appropriately aligned and directed towards the desired illumination area. Use appropriate fixtures or brackets provided with the light for proper installation.
