If you wish to make investments extra money and time to construct a extra elaborate photo voltaic oven, you’ll additionally want wooden to construct a body, instruments to chop the wooden, a drill, and screws.

Elements of a photo voltaic oven 

A easy photo voltaic oven sometimes consists of a cardboard field, aluminum foil, a chunk of glass or Plexiglas, insulation or cotton padding, a thermometer, and a body. 

The field and the foil work collectively to mirror and soak up daylight, trapping the warmth contained in the oven. 

The glass or plexiglass retains the warmth trapped inside (with out blocking the daylight), whereas the insulation or cotton padding prevents warmth loss. 

Moreover, some photo voltaic ovens additionally use reflectors to direct extra daylight into the oven.

Completely different designs

There’s all kinds of designs for photo voltaic ovens.

Probably the most easy design consists of a reflective materials (panel) put collectively in a approach that directs the daylight to a goal (the pan/meals). You’ll be able to name it the “sluggish cooker” of photo voltaic ovens, because it doesn’t lure the warmth “inside” the oven to hurry up the cooking course of.

Nonetheless, it could actually create sufficient warmth to prepare dinner meals should you’re keen to attend lengthy sufficient.

That is what it appears like:

Now, suppose you’re on the lookout for one thing extra intermediate-level. In that case, a normal DIY photo voltaic cooker design consists of a cardboard field coated with aluminum foil and a chunk of glass (and even plastic wrap or baking luggage) on the highest. 

Including flaps wrapped with reflecting materials could make it extra highly effective.

Right here’s an instance:

Any such oven is appropriate for primary cooking as it could actually attain temperatures round 230ºF (110ºC) and as much as 250ºF (121ºC).

If you need a extra sturdy and strong photo voltaic oven, you may construct a wood body and use reflectors to direct extra daylight into the oven. This fashion, it could actually attain temperatures over 300ºF (140ºC).

This design will can help you prepare dinner extra advanced meals:

On this article, we current a easy DIY photo voltaic oven design that’ll enable you perceive how photo voltaic ovens work. Moreover, we offer the instruments to create your individual photo voltaic oven design later.

How To Construct A DIY Photo voltaic Oven

Step 1: Planning

Like several DIY mission, you must begin by establishing a plan.

Determine the scale of your photo voltaic oven. It must be sufficiently big to suit the pan/pot/baking tray you intend to make use of.

For this mission, you’ll want two cardboard bins (one will go inside the opposite, with some insulating materials between them).

After you have your required dimensions, it’s time to sketch your plan.

Step 2: Measuring and slicing

If you have already got the cardboard bins with the specified dimensions, nice. If not, you’ll want to chop them to match the proper dimensions. You should utilize aluminum duct tape to seal the perimeters/corners.

If the inside cardboard field has flaps, hold them. You’ll convert them into reflectors afterward. If not, you can also make flaps utilizing one other cardboard field. Merely minimize out the size and use duct tape as hinges.

Step 3: Getting ready the outer and inside bins

The outer (bigger) cardboard field is the primary physique of this photo voltaic oven, so it must be sturdy sufficient. Alternatively, you may construct a wood body because the outer field.

Use black spray paint to color the underside (inside) of the inside field. As soon as the paint is dry, cowl the within of the smaller field with aluminum foil (solely the perimeters, not the underside). If mandatory, use glue.

Step 4: Including insulation

Place the smaller cardboard field contained in the bigger one, and fill your entire area between them with an insulating materials. Ensure that to insulate the underside, too, not solely the perimeters. Add sufficient to make it tight – the inside field shouldn’t be unfastened contained in the bigger field.

You should utilize shredded paper, cotton padding, items of cardboard, or something that may act as a warmth insulator.

As soon as the insulation is finished, you need to use cardboard items to shut the “hole” between the 2 bins, so it basically turns into one field. At this level, it ought to look one thing like this:

Step 5: Creating reflecting flaps

Wrap the inside field’s flaps with aluminum foil to mirror extra daylight into the oven. If the field doesn’t have flaps, use one other cardboard field to chop items so you need to use them as reflectors.

Use aluminum duct tape to tape the flaps to the perimeters of the field so it acts as a hinge.

Ultimately, it ought to look one thing like this:

Step 6: Make the highest with plexiglass, glass, or plastic

To maintain the warmth contained in the oven whereas letting the daylight in, you’ll must cowl the highest of the field with a clear materials, equivalent to glass, plexiglass, and even plastic/plastic wrap.

In case you select to make use of glass, you need to use styrofoam/polyethylene foam to construct a “body” for the piece of glass, like this:

In case you don’t need to use a glass prime, you may cowl the highest of the oven with plastic wrap once you’re prepared to make use of it.

Step 7: Utilizing the photo voltaic oven

As soon as your photo voltaic oven is prepared, place it exterior below direct daylight.

Alter the reflecting flaps in line with the place of the solar. Then, place the cooking pot containing the meals you need to prepare dinner within the heart of the oven.

Cowl the oven with the glass prime (or with plastic wrap), and that’s it – the photo voltaic oven will do the remainder of the job!

You’ll be able to place a thermometer contained in the oven to watch its inside temperature.

9 Suggestions for utilizing a DIY photo voltaic oven

You’ll be able to take some measures to get probably the most out of your photo voltaic oven cooking expertise.

1. Use black pans: Cowl them with lids or aluminum foil. Darkish-colored pots and pans will soak up extra warmth from the solar and velocity up the cooking course of.
2. Placement is vital: Place the oven going through the solar and alter the reflectors to maximise daylight absorption.
3. Monitor the temperature: Use a thermometer to watch the oven’s inside temperature.
4. Preheating: Preheat the oven earlier than cooking —go away it below the solar for some time earlier than inserting the meals. This can make sure the oven is sizzling sufficient once you place your meals.
5. Begin cooking early within the day: The very best time to prepare dinner with a photo voltaic oven is through the morning and early afternoon when the solar is at its strongest.
6. Add additional insulation: If the oven’s temperature isn’t excessive sufficient to prepare dinner the meals, strive including further insulation layers to the body.
7. Cook dinner in batches: To profit from the warmth, prepare dinner a number of objects concurrently (in case your photo voltaic oven is sufficiently big to suit a number of pans).
8. Defend the oven from the wind: Wind can lower the temperature within the oven, so be certain that to put it in a spot topic to much less wind.
9. Excessive temperatures: A photo voltaic oven can attain excessive temperatures, so watch out with the warmth once you open/take away the glass on prime of the oven (such as you would with a traditional oven).

Closing ideas

Photo voltaic ovens are an efficient and sustainable option to prepare dinner meals with out electrical energy or fuel. What’s extra, they’re fairly simple to construct.

With the best supplies and a few spare time, you may assemble your photo voltaic oven and begin getting ready recent, home-cooked meals., all whereas saving electrical energy!

By following the steps outlined on this information, it is possible for you to to construct a DIY photo voltaic oven that’s environment friendly and easy to make use of.

So, begin constructing your photo voltaic oven right now and revel in the advantages of cooking with the solar’s energy!
