How To Make A Solar Oven

Setting Up & Cooking In Your Solar Oven

How to make a simple solar cooker to understand the use of solar energy

13. Take your solar oven to a spot in your yard that receives unobstructed sunshine. Attach the collectors to the oven by sliding the Slip-In Piece in between pieces of cardboard insulation at the top of the oven. Tilt your solar oven so that its pointed at the sun, and support it using bricks, rocks, overturned clay pots, or other sturdy things. Wearing sunglasses, fine-tune your ovens position by observing the shadows inside the Small Box. Place your food inside the Small Box and set the glass into place. Again, there shouldnt be any gaps between the glass and the top rim of the Small Box, and the glass should be supported by the piece of cardboard insulation that you left sticking up in Step 4.

Positive Sides Of A Solar Oven

How to Make a Solar Oven with @Beau Coffron | The Home Depot Kids Workshops

Before jumping to the main topic lets have a look at some of the positive sides of a solar oven.

Use of Natural Energy

It uses sunlight by condensing the ultraviolet and electromagnetic rays of the sun to produce heat which is required to cook food. The energy derived from these electromagnetic rays causes the molecules of the solid or liquid to move rapidly and generate a huge amount of heat.

Solar ovens trap this heat and utilize it for cooking food. No gas, fuel or artificial energy is involved in the activity of solar oven.


The most important feature of a solar oven is that it does not require constant monitoring as a fuel derived oven would. It can be placed under the sun and kept in that similar position until the cooking is completed.

It can also be kept in a place randomly away from the sunlight and left like that for a few hours. The cooking is completed when the sunlight crosses the side of the oven at alternative phases of the day.


It is affordable as cooking, boiling, and baking almost anything can be done using a solar oven. So, a single solar oven can serve multiple purposes. The materials required to create a solar oven are affordable and budget friendly. So, it serves as a cheap alternative to other cookers which are nowhere near the affordable range.

The only requirement is sunlight and there is no obligation of the usage of firewood or any other elements or materials.

Making A Lightweight Solar Oven

How to Make a Solar Oven
  • 1Place a cardboard box inside a larger cardboard box. Remove the tops of both boxes, and place the small one inside the larger one. Make sure there is at least a gap of 1 inch between the boxes. Glue the smaller cardboard box into place by squeezing glue onto the bottom and then pressing the smaller box firmly into the larger box. XResearch source
  • 2Fill the gap between the boxes with shredded newspaper or torn fabric. Tear the newspaper or fabric into strips, crumple them, and stuff them into the gap between the two boxes. Make sure to entirely fill the gap so there is no empty space.XResearch source
  • The paper or fabric will act as insulation, which keeps the heat trapped inside the oven.
  • 3Line the inside of the smaller box with black construction paper. Cut pieces of black construction paper that are the dimensions of the walls and bottom of your cardboard box. Use glue to paste them in.XResearch source
  • Black absorbs heat very easily, so it will keep your oven toasty.
  • 4Cut trapezoids from cardboard. The narrow side of the trapezoid should be the same width as one side of your large box. This is the side you will attach to the box. The wide edge of the trapezoid should be 2 inches wider than the small edge.XResearch source
  • Use a utility knife to cut the cardboard. Place your cardboard on a scratch-proof surface, like the garage floor to cut it. Always cut in the direction away from your body, to avoid accidentally cutting yourself.XResearch source

    The Science Behind A Diy Solar Oven

    It is useful to understand the working principle of the device you just made. After all, solar ovens work entirely on science.

    Here is the chronology of the solar energy and consequent cooking process.

    • The heat from sun rays enters the box through the transparent plastic wrap opening.
    • Due to the flaps and aluminum materials, the rays get focused in the cooking area.
    • The air trapped inside heats up due to sunlight.
    • Now, you might remember the existence of black construction paper. This paper absorbs maximum heat towards the bottom of the solar oven.
    • In addition, the newspaper tubes help with ineffective insulation. In simple words, the heat doesnt escape the inside of your solar oven.
    • This heat cooks the food kept on a plate within the box. On sunny days, the temperature can cross 150 degrees Fahrenheit.
    • Thus, your solar oven is ready for food to cook on a hot day.

    How To Make Rainbow Crayons:

    This is a perfect recipe for this experiment because its not a food item and demonstrates how your oven works. To make them simply chop some old crayons up and place them into silicon cupcake liners. Place the silicon cupcake liners inside your oven and observe them cooking over time. Taking note of the results will give you a good idea of how your oven cooks when its time to make a food item.

    The hottest our oven got on this day was 80ºC . It was enough to mostly melt the crayons but there were a few chunks left which were obviously not going to change no matter how long we left them in the oven.

    Time To Use The Aluminum Foil

    Make a pizza box solar oven

    The next step is to cover the inner side of the cardboard opening. You can wrap the aluminum foil tightly. Further, with the help of tape, paste this foil firmly inside the box.

    Aluminum works as a reflective material that keeps the sun rays concentrated inside the box. Hence, to make a solar oven efficient, such foil is mandatory.

    Furthermore, repeat the same procedure for each solar oven flap. The trick is to help maintain the temperature of the interior of your DIY solar oven.

    Are Solar Ovens Worth It

    Clearly, solar cookers and ovens have some limitations.

    As with any solar system, they depend on bright, direct sunlight to be effective.

    This limits your cooking to daylight hours and decent weather.

    Solar cooking is often slower than other cooking methods. This means you may have to be in camp for longer and plan your day around the timing of cooking tasks.

    Due to the size of the cooking vessel, it may also be challenging to cook for a large group.

    If you can work with these limitations, a clean, fuel-less cooking system has lots of benefits.

    Its silent, generates no smoke or soot, and can run as long as you have sunlight.

    A lightweight solar cooker can often weigh less than a comparable traditional stove. Plus, it doesnt need heavy, costly fuel.

    While I wouldnt likely make it my primary cooking system in the cloudy Pacific Northwest.

    Ive certainly come to enjoy using my Fresnel lens solar cooker.

    And I plan to build and experiment with other designs in the future.

    I Just Found These The Perfect Pots And Lid

    I didn’t know if I should put these in the associated steps or just add them as an epilogue …so I decided to put them where a returning viewer may notice. I was at IKEA and spotted this set of matt-black painted aluminum pots for less than $13 and this package of dark-grey rigid silicon lids for $8 . I would have bought the smallest lid I would have bought just it because it’s perfect for for all 3 pots. But my wife wanted the larger ones so it was a no-brainer to by the set. But, if you want a lid for each pot you can easily cut them down to size with a pair of scissors

    Total cost: 12 Euros

    These are PERFECT for almost any size solar oven AND the handles are screwed on, so it you want to remove them for storage you can do that. Or, if you want leave the handles on, but they are too big for your oven, they are made of plastic so you can cut them off to any length required. I plan on leaving mine on for now but my take them off at a latter date.

    I included the product label for faster look up on the IKEA catalog if you want to check for local availability.

    Editors note: these are much cheaper than a set of good aluminum camping cookware, so if you’re looking for a good set, look no further!
