1. Remove the Pull Tab
If your solar string lights are brand new, let them charge before using them. Because they are not fully charged. Another thing is to remove the battery tab or strip.
The strip or pull tab is present between the battery and terminal. It is used to preserve the batteries from draining out during shipping. So, you have to remove the pull tab or strip before using it.
2. Deep Charge Your Lights
A common reason behind solar lights not working is an insufficient charge. The sunlight is not available in plenty or the batteries are not fully charged. You should apply the deep charge technique.
- Switch OFF your solar string lights.
- Charge them fully for 72 hours.
- Do not use lights while they are on a deep charge.
- After 72 hours, turn the lights ON and check.
3. Check the Cable and Connection
Solar string lights are connected to the panel via cable. This connection wire may be damaged or faulty. Therefore, your lights cannot get power. So, examine the entire cable. Look for any exposed or damaged areas.
Tape the defective parts. Sometimes, animals chew the cable. If it is too damaged, replace the connection cable. Moreover, plug the cable firmly into the panel. Make sure the connection is not loose.
4. Clean the Solar Panel
As you know, sunlight is very essential for running solar lights. So, if the panels are dirty, the quality of light can be compromised. Since they are installed outdoors, solar panels are vulnerable to dirt and moisture.
All you have to do is clean your panels fully to remove any dust or debris.
- First, remove the dirt with a dry cloth.
- Scrub a soft cloth to remove sticky marks or debris from the surface.
- You can wash it off with clean water.
- Let the panels dry in the air.
- Once they are completely clean and dry, check the lights again.
5. Check the Sensor
Solar lights are equipped with a light-sensitive sensor. It shuts them off during the day and turns them on during the night. However, a faulty sensor leads to a problem.
The string cannot differentiate between day and night. Hence, the power is drained out during the day. The solution is to manually switch off the lights during the daytime. Fix the sensor to solve the issue permanently.
6. Replace the Batteries
One of the main reasons is that the batteries of your solar string are expired. Most solar lights come with rechargeable batteries that store power.
However, these batteries can die after living their lifespan. So, check and replace the dead batteries. Purchase a high-quality product for replacement.
7. Check for Water Damage
Almost all solar lights come with Ingress Protection. This feature protects them from harsh weather and water damage. However, still they can suffer water intrusion.
If water enters the panels, it damages the circuit board and wiring. Thus, your strings stop working at all.
