How to Make Solar Panel from CD: Step-by-Step Guide

Here’s a step-by-step guide on how to make solar panel from CD:

Step 1: Prepare the Materials

Gather all the necessary materials and tools mentioned earlier: soldering iron with a thin rod, multiple CDs, silicone sealant, double-sided adhesive tape, soldering supplies, copper wire, fasteners, drill, plywood or plexiglass, and Schottky diodes.

Step 2: Design the Layout

Plan the arrangement of the CDs on the plywood or plexiglass substrate. Ensure there’s enough space for the CDs to be attached in rows or a desired pattern.

Step 3: Attach CDs

Use double-sided adhesive tape to secure the CDs onto the plywood or plexiglass, arranging them according to your layout design.

Step 4: Connect the Solar Cells

Solder the Schottky diodes to the back of the solar cells. These diodes prevent reverse current flow and protect the cells. Then, solder the solar cells to each CD, creating a series or parallel connection, depending on your design and desired voltage/current output.

Step 5: Wire Connections

Using copper wire, create electrical connections between the solar cells. Solder the wires onto the solar cell contacts, ensuring proper polarity and secure connections.

Step 6: Seal and Insulate

Apply silicone sealant around the solar cells, wiring, and connections. This seals the components and provides protection against moisture and environmental factors.

Step 7: Mount the Substrate

Use the fasteners and drill to attach the plywood or plexiglass substrate with the attached CDs to a sturdy frame or support structure. Ensure the panel is securely mounted and positioned for optimal sunlight exposure.

Step 8: Test and Install

Place the completed CD solar panel in direct sunlight. Use a multimeter to measure the voltage and current output to ensure the panel is generating electricity. If everything is working as expected, install the panel in a sunny location.

Step 9: Maintenance and Monitoring

Regularly inspect the panel for any signs of damage or deterioration. Clean the CDs and solar cells to maintain optimal efficiency. Monitor the performance of the panel over time and make any necessary adjustments.

Remember to exercise caution while working with soldering irons and tools. Prioritize safety and follow proper soldering techniques to ensure reliable connections. Adjust the steps as needed based on your specific design and materials.

Pros and Cons of CD Solar Panel

pros and cons of cd solar panel - how to make a solar panel with cd?

The following are the advantages and disadvantages of a CD solar panel DIY, with a focus on the former:


  • Cost-Effective: Reusing old CDs lowers the cost of materials, which makes CD solar panels an affordable way to experiment with solar power.
