You can repurpose the plain old CDs to the fullest extent. You can take advantage of their distinctively shiny surfaces to build a solar heating panel or a solar power tower (heliostats).

Follow the demonstration later for a complete guide to make a solar panel with CD to produce your solar power.
Although, this energy won’t power your home electronic appliances. The article is not about a traditional solar panel you can expect to build.

And that raises the question, how will you benefit from this endeavor?

Who benefits from “make a solar panel with CD” projects?

Suppose the world’s temperatures increase to 1.5°C. In that case, we will lose 70 – 90 % of coral reefs, according to a report by IPCC.  [I]

As climate change continues to threaten our environment, renewable energy deployment is becoming quite commonplace.

But what is the best form of renewable energy?

Green technologies substantially depend on the sun directly or indirectly. The sun’s rays’ conversion through photovoltaic cells or reflective mirrors makes solar power the most significant contributor to renewable energy.

The demonstration of making a Solar Thermal Panel with CD should benefit us. It should improve our understanding of how you can utilize the sun to produce heat energy and heal through snowy days. 

While it is a unique method to produce heat, it might not help make power.

The practical applications (included but not limited to) of this project are

  • Educating yourself

Whether you are a grown-up or a child, you can educate yourself through such a small-scale solar project without wasting a lot of time, money, or energy.  You can observe the power of the sun’s rays first-hand.

  • Instant gratification

A relatively lighter project will still be brighter if you can get an immediate result of your effort.

  • Off-grid applications

Suppose your power sources are cut or you’re away from the power grid. In that case, this endeavor will prepare you to adapt to off-grid applications. You can efficiently progress your real-life solar power project. You will be able to adapt to survive and build your solar system.

How do you generate solar energy with a CD?

– The solar photovoltaic (PV) cells are more efficient at absorbing photons if you can imprint quasi-random nanostructures (non-smooth) on the solar cells. Even though it looks smooth, a Blu-ray disc has ‘islands’ and ‘pits.’ This surface pattern gives them the ability for light-trapping. A Blu-ray-patterned solar panel can absorb 21.8 % more lights comparing to a non-patterned solar panel. [II]

– Unlike the CDs and DVDs, the Blu-ray discs have a higher capacity, transfer rate, and ability to improve solar PV panels’ efficiency. The information patterns (imprinted) of Blu-ray discs work so well to concentrate lights. This technique can improve the efficiency of polymer or other types of solar cells.

However, it is pretty costly to construct the molds for fabrication.

Let’s see the processing of such Blu-ray-patterned solar cells below:

How can I make a simple solar panel at home with a CD?: DIY Step by step Guide of Making simple solar panel with cd-

The traditional solar photovoltaic panel produces electrical power through the photovoltaic process (convert sun’s rays into useable energy).

In comparison, the solar thermal panel reflects the sun’s rays to heat a particular object, fluid, or area.

Although they do not convert the sun’s rays into electricity, they are crucial to the solar platform.

You do not require battery or inverter integration with the solar panels.

The process is less sophisticated than that of a grid-connected system. The technology is not any less valuable than that of the photovoltaic generation as well.

How to make a solar panel with cd? Step by Step Guide

1st step for making a solar panel with CD : Measure and Cut

  • At first, measure the length and the width of a window south-facing or otherwise. Add 4/8 inches to the length and width as well. For instance,


Length Width
Actual 22 36
Required 26 40


Now, pick a cardboard piece large enough to shape it with a utility knife according to the required measurements above.

From any unused cardboard, cut few rectangles (4 pieces) of 4-inches width. The rectangles should also be 3/4 of the width of the container.


2nd step for making a solar panel with CD : Paint

  • Move forward to the next step, spray on any one side of the cardboard, preferably black entirely, as dark colors absorb the highest light energy (heat) from the environment. You can apply a coating material for the best result or an enhanced aesthetics. But you must wait half a day or more to let dry the paint thoroughly before using any other colors.


3rd step : Create a Container –

  • With the utility knife, cut a 4-inch square from every corner of the rectangle cardboard and tape them up with the masking tape to create a container. The dark section should form the inside of the box.


4th step for making a solar panel with CD : Placement

  • Insert the CDs into the container in uniform columns& rows from bottom to top of the cardboard with the non-reflective side facing inward.
  • Next, use a pencil to locate the midpoint of the CD rows. Cut a hole from both the top and bottom rows of CDs to glue them down over the holes.


5th step for making a solar panel with CD : Glue the Rectangles

Take the four rectangles from the first step and glue them inwards of the container to form a maze wall.

Rectangles 1st 2nd 3rd 4th
Position in container Left  side Right side Left side Right side
Position at CD rows Bottom row

Top row


6th step for making a solar panel with CD : Hooking Arrangement

  • In the last step, pick a drop cloth piece of overall length to shape it 3 inches longer and wider than the container with a utility knife.


  • Unfold the cloth over the top gluing the sides of the container. Make holes in the two upper corners of the container to inject the S-hooks. Finally, you can hang the solar thermal panel on the window.


Conclusions for make homemade solar panels with CD: Why is solar power the best energy source?

This technological era of YouTubes or iTunes made the CD, DVD & Blue-ray discs outdated relics.

Nevertheless, you can upcycle the obsolete discs to bring them back into existence. You can utilize the shiny sides of old plastic disks to create an electricity-generating solar panel or solar heating thermal panel.

  • You can repurpose your old CDs from the pile of useless CDs, DVDs & Blue-ray discs lying around the house or in your backyard!

FAQ: How to make solar cell with copper wire, cd, and diodes?

The electrical conductivity of copper is one of the best among the metals. Although, it cannot generate electricity when exposed to just sunlight. Unless, you swing a magnet around a coil of copper wire.

The Zener diodes, however, can produce some measurable voltage when exposed to sunlight.

The diodes are only capable of producing only a couple of millivolts. You can test it with a voltmeter or multimeter.

But it will not essentially run any electronic devices as the current output will be tremendously low and hence the power.

The DIY videos on YouTube to build CD solar panels with copper wire and diodes won’t provide sufficient energy to power any home electronic appliances.
