Save Money Using a Solar Oven

Just got my new solar oven a week ago and I am loving it! I’ve cooked in it once or twice a day since receiving it. It’s very easy to use and is powered completely by the sun. I save money I would have spent on electricity to run my kitchen oven and again by not having to run the AC to cool the house back down afterward. This means a lot in Texas in August! I’m also saving by not eating out as much or using expensive convenience foods as much since the solar oven is so easy and fun to use. From electricity savings reports from other solar oven users I should recoup my cost for the oven in less than six months. The oven is built to last 15 years or more.

The oven I chose is a Global Sun Oven. It is a little more costly than some other solar ovens but is built to last many years and is very well insulated and seals tightly to reach higher temperatures and keep food warm longer. The oven is very portable and light weight. It weighs 21 pounds and quickly folds down to the size of a small suitcase with a built-in carrying handle.

The oven is also great to have for emergencies. If you don’t know if your water is safe to drink put it in a dark pot with a lid in the oven. I have a Water Pasteurizing Indicator (WAPI) that I can drop in the water. The wax in the WAPI melts at exactly 150 degrees after 6 minutes which indicates the water is safe to drink. The oven can also be used to heat bath water, sanitize dishes or dry wet firewood during a power outage.

For my oven’s first test run I put in a whole chicken, several whole Yukon gold potatoes, a few carrots, a sweet potato and a whole onion sliced in half. I used a 15-inch black graniteware roasting pan.(this is the largest roaster that will fit in this oven) I left the food in the oven for about 3 1/2 hours with temps fluctuating between 300 and 350 degrees.

The chicken came out very juicy and falling off the bones. The sweet potatoes were melt-in-your-mouth good. The other veggies were tasty also. The carrots were slightly over done but came out great the next time when I put them in whole instead of chopping them into small slices.

Thin dark metal pans work best for solar applications. Shiny pans should not be used as they reflect the sun’s rays back out of the oven. If you don’t have any other pans available you can drape a dark tea towel over the shiny pans. Make sure the towel is all cotton. Synthetics may melt. Glass or cast iron pans can be used but take longer to heat up than the thin dark metal. A pot with a tight-fitting lid should be used over all foods except baked goods. Without a lid steam will rise and cover the glass blocking out much of the suns rays.

To keep the highest possible temp the oven needs to be turned slightly every 30 minutes or so. Turn until the shadows on each side are even. If the sun is low in the sky there is an adjustable leg on the rear that can tilt the oven until there are no shadows inside the cooking chamber. If you will be gone for hours you can use the oven as a slow cooker. Just point it south. The insulated chamber will keep the food warm up to an hour after the sun goes down or

longer if you use a cast iron pot and lid. As long as there is sun the oven can be used no matter how cold the temps are. Sun Ovens have been used successfully at base camps of Mt. Everest where it gets below zero degrees.

Food in the solar oven never needs to be stirred. The heat rises slowly and evenly in the whole chamber so there are no hotspots. Anything that can be cooked on the stovetop or in a regular oven can be cooked in the solar oven except for fried foods. Cookies are about the only food you have to worry about burning in the sun oven due to their high sugar/fat content. I baked some peanut butter cookies today.

I used stacking dehydrator racks to get 3 levels of cookies in the oven at once. They took 20-30 minutes to cook. In the regular oven they take about 10 minutes. The top rack was done sooner than the lower racks. I used small toaster oven cookie sheets on the top two racks and parchment paper on the bottom rack. The cookies have a slightly chewier texture from being cooked more slowly at a lower temp.

The oven can also be used for dehydrating foods. I have not yet had a chance to try this. I have three special

dehydrating racks that fit into the oven at once. To dehydrate you would just turn the knobs that seal the glass door inward so it doesn’t seal allowing air to circulate. If insects are a problem you can cover the opening with netting. Fruits and vegetables take a day to dry. Meats may take 2 days. Seal it up at night and open it back in the morning to keep insects out if the drying takes more than one day.

I am in LOVE with my new solar oven. If you want to cook amazing food without using any fuel or heating up your kitchen try a solar
