This article delves into the practicalities of using the sun's inexhaustible energy to dehydrate food, sharing personal experiences, challenges, and solutions. Learn how to harness solar power effectively, save on energy costs, and enjoy the benefits of sustainable living.

The Journey to Solar Cooking

My wife and I have been living full-time in a 40-foot motorhome for over three years,Solar Oven Cooking and Food Dehydration: DIY Solar Oven Dehydrator Kit Articles having sold our house and donated everything to Disabled American Veterans. This nomadic lifestyle has its challenges, especially when it comes to cooking and energy consumption. Without access to shore power, we rely on a generator to power our oven, toaster, microwave, and charge our house batteries. Running the generator multiple times a day consumes diesel, which is more expensive than gasoline. Cooking in a small space also heats up the RV, making it uncomfortable during hot summer days.

The Solar Oven Revelation

A year ago, I discovered solar sun ovens and purchased two just in time for Christmas. This marked the beginning of our love affair with solar cooking and baking. Solar ovens use the sun's energy to cook food, eliminating the need for a generator and reducing our diesel consumption. However, my first attempt at dehydrating food with a solar oven was far from successful.

The Dehydration Debacle

I naively thought that dehydrating food with a solar oven would be straightforward. However, my first experiment with sliced bananas resulted in them cooking onto the drying racks, creating a mess that was impossible to clean. After some research, I learned that the ideal temperature for dehydrating food is much lower than the 350 degrees Fahrenheit I had used.

Ideal Dehydration Temperatures

  • Jerky: 145-200°F
  • Tomatoes and Bananas: 120-145°F

Solar ovens lack a thermostatic control knob, making it challenging to maintain these precise temperatures. Solar ovens essentially have two settings: sunny and shady.

The DIY Solar Oven Dehydrator Kit

Determined to make solar dehydration work, I experimented with various techniques. I eventually created a solar oven dehydrator kit by placing a small fan at the bottom of the stacked racks and connecting it to a small solar panel. I propped the oven door open slightly to allow airflow, which helped maintain the temperature between 120 and 145 degrees Fahrenheit.

Steps to Create a Solar Oven Dehydrator Kit

  1. Position the Oven: Align the solar oven directly with the sun.
  2. Add a Fan: Place a small fan at the bottom of the stacked racks and connect it to a solar panel.
  3. Prop the Door: Turn the door latches inward and rest the door on them, leaving it open about half an inch.

This setup allowed me to dehydrate bananas and tomatoes successfully. The bananas turned out crispy and dry, while the tomatoes dehydrated perfectly.

The Benefits of Solar Dehydration

Using a solar oven for dehydration offers several benefits:

  • Energy Savings: Solar ovens eliminate the need for electricity or fuel, reducing energy costs.
  • Sustainability: Solar cooking is an eco-friendly alternative that reduces carbon emissions.
  • Convenience: Solar ovens are portable and can be used anywhere with sufficient sunlight.
