Solar lights have revolutionized the way we light our outdoor spaces. They are cost-effective, environmentally friendly, and easy to install. However, sometimes the cable provided with solar lights may not be long enough to reach your desired location or may get damaged. In this guide, we will explain how to extend a solar light cable in a few simple steps.

Step 1: Measure the Required Length of Cable

The first step is to measure the length of cable required to extend the solar light. This can be done by measuring the distance from the solar panel to the desired location of the light. It is important to add an extra foot or two to the measurement to allow for any twists or turns.

Step 2: Purchase Extension Cable

Once you have determined the required length of cable, the next step is to purchase an extension cable. Extension cables are readily available at hardware stores or online retailers. Make sure to purchase a cable that matches the gauge of the existing cable. This information should be printed on the original cable or can be found in the instruction manual.

Step 3: Cut the Existing Cable

Using wire cutters, cut the existing cable at the point where you want to extend it. Leave a few inches of cable on either side of the cut to work with.

Step 4: Strip the Wires

Strip the insulation off both ends of the cut cable using wire strippers. Be careful not to nick or damage the copper wires inside.

Step 5: Connect the Extension Cable

Take the extension cable and strip the insulation off both ends using wire strippers. Twist the copper wires together with the copper wires from the existing cable. Use wire nuts or electrical tape to secure the connection. Make sure the connection is tight and secure to prevent any water from entering.

Step 6: Test the Connection

Once you have connected the extension cable, test the connection by turning on the solar light. Make sure the light is functioning properly and that there are no issues with the connection.

Step 7: Insulate the Connection

Using electrical tape, wrap the connection to insulate it from the elements. This will prevent water and other debris from entering the connection and causing damage.

Step 8: Bury the Cable

If the extension cable is going to be buried underground, use a shovel or trenching tool to dig a trench. Lay the cable in the trench and cover it with dirt. Be careful not to damage the cable during the burying process.


Extending a solar light cable is a simple process that can be completed in a few steps. By following these steps, you can ensure that your solar light is placed exactly where you want it without having to worry about the length of the cable. Remember to take all necessary safety precautions when working with electricity, and always test the connection before burying the cable. With a little bit of effort, you can extend your solar light cable and enjoy the benefits of solar lighting in any outdoor space.
