Why All-in-one Integrated Solar Street Lights May Not Work?

If the newly installed  all-in-one integrated solar street lightdoes not light up within a week, you can check for the following reasons. Typically,all-in-one integrated solar street lights not lighting up can be caused by the following situations.

Check if the installation site of the all-in-one integrated solar street lightreceives sufficient sunlight

Although the all-in-one integrated solar street light can absorb light energy even on cloudy days, if the installation site has poor lighting conditions, the solar cells will not effectively absorb and store energy. Therefore, it is necessary to check whether the installation site of the all-in-one integrated solar street light has good lighting. If the lighting is insufficient, consider relocating the installation or trimming surrounding obstructions to improve lighting.

Check if the LED light source of the all-in-one integrated solar street light is soldered firmly

Currently, most all-in-one integrated solar street lights use LEDs as the light source. It is essential to check if the LED light source is soldered firmly and if there are any issues with poor contact. If you find that some LED beads are not lighting up, you can replace the non-functioning beads or re-solder any loose beads.

Check if the circuit of the all-in-one integrated solar street light is intact

In rural areas, a common reason for solar street lights not lighting up is poor circuit contact. This can easily lead to insufficient power supply from the solar cells, reduced storage capacity, and unstable power, causing the street light to flicker. If faced with poor circuit contact, immediately check and replace any damaged or poorly connected wires.

Check if the battery of the all-in-one integrated solar street light is aging

All-in-one integrated solar street lights have long battery life, but due to prolonged usage, the battery may age, resulting in shorter lighting times. Therefore, carefully examine the energy storage status of the solar street light's battery. If the battery is aging, consider replacing it.

Check if the controller of the all-in-one integrated solar street light is damaged

A common misconception is that a non-functioning all-in-one integrated solar street light is due to a faulty controller. The controller is the core component that coordinates the operation of all systems. The steps to check the controller are as follows:

• Check if the battery voltage is correct. If the battery voltage is below the low-voltage protection value of the controller, the controller will stop input, causing the solar street light to not light up.

  
  

• Check if the controller's wiring is secure and if there are any loose or poor contacts.

• Check the controller's settings to ensure the operational mode and timing settings are correct.

By following the above steps, you can identify the reasons why the integrated all-in-one solar street lightis not lighting up and resolve the issue accordingly to ensure the proper functioning of the street light. If the issue cannot be resolved, it is recommended to contact professional solar street light repair personnel for further inspection and repair.
