How do solar ovens work?

The best way to answer this question is to learn how to make solar oven ideas by yourself by awakening your inner Einstein. Follow this guide, as I have explained below.

Materials Required

The primary materials that you need for creating homemade solar ovens are:

  • A metal drum
  • A sheet of metal
  • An aluminum sheet
  • Scrubber with soap
  • Reflective paint
  • A strip of cardboard
  • Insulation spray
  • A rectangular wooden frame
  • Metal driller
  • Tempered glass
  • Aluminum racks
  • Wood stove Thermometer
  • ⅛” pop rivets

1. Slice Open The Metal Drum

The first step is to take a jigsaw chainsaw and slice open the metal drum in half vertically. ou only need one half of the metal drum, you can discard the other half if you want to.

2. Clean The Drum Inside Out.

After you slice the metal drum, clean the insides thoroughly. Use a scrubber with a non-greasy soap to make cleaning the insides easier. Ensure you clean it enough to make it gleam under the sunlight.

3. Cover The Interior Of The Drum With A Metal Sheet.

After cleaning the insides, stick the metal sheet with the insides of the metal drum. For the best fit, measure the curved inside of the drum with a measuring tape and cut or buy a metal sheet of its size.

To attach this metal sheet, you must drill ⅛” holes along the sides. You must have pop rivets of the same size as the holes (⅛”).

Safety Note: Wear goggles if you are cutting the metal sheet.

4. Cover The Ends Of The Drum

Now the curved inside of this metal drum is covered, it’s time to cover the round ends. For this job, make semicircular lids with the same sheet of metal as used above.

5. Apply Reflective Paint In The Inside

You have finished with the coverings, it’s time to awaken the Van Gogh inside you. Paint the insides entirely with reflective paint. This will ensure that it can reflect the maximum heat on the food. Ensure that you are using eco friendly paint.

6. Make A Metal Lip With Three Edges

To attach the sheet of glass to DIY solar ovens, you need to create a lip on the top. You can do by creating it with six metal flashings. Here’s how you can create the metal lip flashings:

  • Create a flashing sandwich of two layers by placing cardboard in and drilling the layers.
  • Attach a rivet near the bottom to attach it to the edges of the metal drum.

7. Spray Insulation On The Outside

Flip the metal drum over and apply a thin layer of insulation spray on its outside. This will ensure that the heat absorbed stays inside and doesn’t get emitted outside. This is necessary you don’t have a solar panel setup attached to this.

8. Attach A Wooden Base On The Bottom.

To ensure solar ovens are cookable, you ensure stay in place and don’t roll for their curved bottom. Create a big enough rectangular wooden frame and place this solar oven on top of it.

9. Drill Drainage Holes

Inside the metal drum, drill a line of holes that are three inches apart from each other. It should drill the insulation layer too. This will help all the vapor to escape in cooking. You don’t need air sealing here.

10. Cover The Metal Lip With Tempered Glass.

Now, slide the tempered glass on top of the metal drum. Ensure that it fits perfectly between the metal lips. Ensure that the tempered glass is 3/16” or 0.48 cm thick.

11. Place A Thermometer Inside (Optional).

If you want, you can place a wood stove circular thermometer. This type of thermometer is recommended for it can withstand the heat absorbed by the metal inside.

12. Cover The Bottom With Aluminum Racks From The Inside.

Place aluminum racks on the inside of this homemade solar oven. Ensure they are straight and won’t cause your cooked food to tilt and fall.
