How to Make a Solar Panel With Aluminum Foil

One of the most common ways to power homes and businesses is by using a solar panel. This unit sits on the roof of your building, absorbs the sun’s heat, and produces electricity that can be used to power your home or business during the day. But with so many different types of solar panels on the market today, it can be difficult to know which is best for you. That’s why we put together a guide to help you make your own solar panel out of aluminum foil. After following these simple steps, you will be able to generate your own green electricity using nothing but aluminum foil and sunshine!

How To Make A Solar Panel With Aluminum Foil?

1. Find a clear, flat surface to work on. The best place to make your solar panel is out of direct sunlight. If you want to use it indoors, then find a sunny window where you can place it.

2. Cut up an aluminum foil sheet in the shape of a rectangle or square and place it on the surface that you’ve chosen for your solar panel.

3. In order for the aluminum foil to absorb sunlight, fold it over and put one side down on the table or surface that you’re working on. Then fold the other side over so that there are no gaps between the two pieces of aluminum foil and you have a very thick piece of aluminum foil with both sides folded over toward each other.

4. Now take one end of this piece of folded aluminum foil and place it on top of your solar cell (the part where the light shines through). Make sure that there is no space between this end and your solar cell so that light will shine all the way through the piece of folded aluminum foil onto your solar cell – there should be no air pockets between these two pieces!

5. Next, take another piece of folded aluminum foil, this time without any folds, and put this piece in between your previous folded section as pictured above (this is called sandwiching). Make sure that this second piece has enough space in-between so that when you fold over these two pieces together they won’t be touching each other but will instead be touching the piece of aluminum foil in the middle.

6. Next, take the second piece of aluminum foil that you placed in-between your previous folded section and put it on top of your first piece (the one with no folds). Now you should have this very thick piece of aluminum foil sandwiched between two pieces of folded aluminum foil with a gap in-between them (see above picture).

7. Finally, cut these three pieces of folded aluminum foil into two equal sections – one piece should be the size that fits over your solar cell while the other should be the size that fits over the bottom part of your solar cell (see below picture). Then fold up these two pieces together so that they are very close to one another and then secure them by putting tape or electrical tape around them to make sure that they don’t come apart when exposed to sunlight.

8. Finally, place this whole thing on top of your solar cell! In order to make sure it stays put, you can use a couple of pieces of tape or electrical tape around it as well as a couple of rubber bands around each end to hold it in place.

9. Lastly, make sure there is some kind of ventilation underneath where you’ve placed this solar panel so that any heat from your solar panel doesn’t build up too much and melt your plastic table or surface underneath it! That’s all there is to make a homemade solar panel out of aluminum foil – now go get some sunshine!

How Do Solar Panels Generate Electricity?

1. The solar panel consists of a photovoltaic cell that converts sunlight directly into electricity. You can see the photovoltaic cell in the picture above.

2. The solar cell is made up of two parts: a semiconductor (which is the bottom part) and a p-n junction (which is the top part).

3. When you shine a light on the p-n junction, electrons flow from it to the semiconductor and create an electric current that can be used as power. This process is called the photoelectric effect.

4. The photovoltaic cell consists of two parts: a p-n junction and a semiconductor material such as silicon or cadmium telluride (this type of solar cell is commonly referred to as a “thin-film” solar cell).

5. When light strikes this thin film, it traps some of that energy within it and begins to heat up – in order for this heat to escape, electrons jump from one side of this thin film to another across this p-n junction.

6. This current flows through wires placed inside your home or building in order for you to use that electricity for something useful like lighting or refrigeration. For example, when food goes bad in your refrigerator, all that food is going bad because there’s no way for any excess energy from your solar panels to escape because there are no wires attached! So you have all these perfectly good fruits and vegetables rotting away while the rest of your food is perfectly good and fresh.

7. If a solar panel generates so much electricity that it can’t be stored, it goes back to the store where it was purchased and is used to power something like an electrical converter that can convert that energy into usable forms of energy like heat, light, or electricity.

How To Use Your Aluminum Foil Solar Panel?

Step 1: Get a roll of aluminum foil and two pieces of tape.

Step 2: Place the foil on a flat surface with the shiny side facing up.

Step 3: Take one piece of tape and stick it on the back (the shiny side) of the foil, leaving about
an inch of space between the tape and the edge of where you will start sticking your cuts.

Step 4: Start cutting along that line with a box cutter or other sharp object, making sure to make each cut at least 1 inch long.

Step 5: Be careful not to cut through your tape’s sticky side!


You can use aluminum foil to make a solar panel to generate electricity. This project is easy and can be done in just a few steps.
