Oh the variety and solar oven designs out there these days! You can get a parabolic that will have your ham & cheese sandwich done in seconds, or burnt to ashes if you don’t watch it. The wonderful evacuated tube models can sometimes cause food to suffer similarly, if you don’t mind them. For some panel cookers, especially depending on your latitude, you may be waiting awhile for thorough cooking.¬† Don’t get me wrong, all these models serve their purpose very well!

With a double box solar oven, it is very difficult, to impossible, to burn any food. The other advantage of a big solar oven, like a box style cooker, is the generally large cooking chamber. If properly focused, and with plentiful sunshine, the box cooker usually only requires a few hours to prepare a typical meal. Depending upon the model, you can usually get a couple pots of food cooking simultaneously. This allows for bigger portions and servings for family and guests. This is an advantage not always used, especially if you may be hiking on a trail alone, on the beach with friends, or simply your back patio.

Stacking in solar ovens, solar cooking stacking

The Solavore Solar Oven goes anywhere and cooks a lot!


The other great advantage of a solar box oven, is that often the pots or baking pans can be stacked in the cooking chamber. For example, you may have a 3 quart pot of stew in there, but can also set a 9 inch baking pan, or cookie sheet into the chamber. It’s great! You can have your main course as well as dessert!

With some big solar ovens, like the Solavore Sport, three items, sometimes four, can be cooking: two, 3-quart pots plus the aforementioned cookie tray, baking pan, bread pan, etc. It’s easier than you may think to accomplish this.


Here’s how it can look in the Solavore Sport Oven:

In this oven, it’s easy to stack up the trays, plates, pots and pans. While remaining a light-weight and very portable solar oven, this model has a large chamber to cook loads of food simultaneously. Here’s how it all turned out:

So, if you have a large, double box solar oven, give stacking a fair try. Sometimes it takes more than one chance to be successful. But the rewards of cooking several meals at the same time are really enjoyable.

Very well, we think! Really, the double box solar oven is a simple, but efficient design. It is a box within a box with the two boxes separated by insulation (the non-toxic variety). There are many great plans out there to construct solar ovens, from using plywood, cardboard boxes and even pizza boxes.

However, here, we are discussing the normal commercial model.The outside box, essentially the case, which is usually equipped with a carrying handle, a feature loved by campers and hikers. It is typically made from a durable, black plastic. The inside box is usually comprised of aluminum with a anodized black, non toxic paint surface. It becomes the cooking chamber for the oven; where you put your potful of food. A double paned glass or plastic lid covers all and often has a seal to prevent air leakage. Also, clips or catches allow the tight closure of the lid for proper cooking. Most commercial models also include polished aluminum reflectors to enhance solar power and speed up cooking temperatures and time. By including, say, your soup ingredients into a dark colored thin-walled metal pot (granite-ware, stoneware type pots) the input of strong sunshine multiplies the green house effect and cooking temperatures can often be reached in less than twenty minutes.

Realistically, 220 to 300 degree temperatures are more common. This is sufficient to bake bread, make soup or stew, bake vegetables, pasteurize water, etc. in just a few hours.You get the picture, right? If conditions are excellent, and you have preheated your solar oven, temperatures of 400 degrees F are possible! But, it’s best to think of your solar oven as a solar powered crock pot. Lower temperatures allow thorough cooking of the food in its own juices. For many dishes, adding water is not necessary. Another benefit of solar cooking is the retention of vitamins and minerals of the meal. Try to cook your double box solar oven meal between 10am and 3pm if you are in the northern hemisphere.

Doing your part to save the planet is a “breeze” by breaking out your solar oven. Most commercial solar cookers are simple to use and set up in minutes. Prepare your next meal (providing it’s a sunny day) with a solar oven and use the sun’s free energy to do it.

Keep your solar oven on a back porch or patio with accessories close bye. Have a list of recipes and foods so you are ready to get cooking with sun power. By using just solar energy, you save money and the planet at the same time. No need to use gas or electric to make a meal on a sunny day; just set up a sun oven.

Loads of recipes are available for solar ovens, but you’ll find that many of your own traditional dishes can be made in them. Since most¬† ovens reach temperatures of between 250 and 400 degrees, depending on the quality of sunshine, it may just take a little longer to cook the meal (this concerns the typical double box solar oven style). Just think of your oven as a solar crock pot. The slow, even cooking allows foods to cook in their own juices. Healthy vitamins and minerals are retained this way. You’ll find less liquids need to be added to solar cooked food. Start cooking with the sun to be “greener”.
