With a few inexpensive household materials, you can build a safe and effective oven that can utilize the sun’s power to generate interior temperatures in excess of 200 degrees Fahrenheit. That’s hot enough to cook sausages, bacon, hash browns, or tater tots.
How is a solar oven made?
Solar ovens use solar energy—light and heat emitted from the sun—to cook food. The solar oven you will build in this activity is a relatively simple one made out of a pizza box, aluminum foil, plastic wrap and a sheet of black paper. You will cut a flap out of the pizza box’s lid and line this flap with aluminum foil.
What materials can be used to make a solar oven?

- Cardboard pizza box.
- Pencil.
- Ruler.
- Box cutter or scissors.
- Aluminum foil.

What is the best insulator for a solar oven?
Good insulating materials include: aluminum foil (radiant reflector), feathers (down feathers are best), spun fiberglass, rockwool, cellulose, rice hulls, wool, straw, and crumpled newspaper.
What does plastic wrap do in a solar oven?
The foil reflects the ray, and bounces it into the opening of the box. Once it has gone through the plastic wrap, it heats up the air that is trapped inside. The black paper absorbs the heat at the bottom of the oven, and the plastic wrap helps the heat stay inside the box to cook the food.
How hot does a homemade solar oven get?
The solar box cooker typically reaches a temperature of 150 °C (300 °F). This is not as hot as a standard oven, but still hot enough to cook food over a somewhat longer period of time.
What is the best shape for a solar oven?
The parabolic style tends to be more effective, reaching higher temperatures and faster cook times, but is expensive and requires frequent adjustments. The panel style cooker can be very cheap and easy to build, but often are not as effective as the other models.

Use a box knife or sharp scissors to cut a flap in the lid of the pizza box.
How do you make a solar cooker?
Directions to make a Solar Powered Oven: Draw a border (at least one inch) around all four sides of the top of a pizza box. Cut along three sides leaving the line along the back of the box uncut. Gently fold the flap back along the uncut edge to form a crease. Wrap the underside (inside) face of this flap with aluminum foil.
