Solar Oven

solar-oven-principle

The solar oven works following the principle of the greenhouse effect:  the sun’s short-wave rays cross the two glass walls without losing energy.  In touching the internal walls of the oven which are covered with a non-toxic paint, they are transformed into heat rays that can no longer cross the glass walls.  This creates an energy trap  that allows us to cook or heat meals.

Usage Advice

The solar oven is easy to use: After placing the meal in the black tank, the oven is placed in the sun, oriented in the direction of the sun’s rays.  Cooking time depends on the intensity of the sun and the meal to be cooked. The empty solar oven achieves temperatures of around 180°C.

Guidelines for the Solar Oven
  • There is not a lot of evaporation from the solar oven - most dishes require less liquid.
  • Amount of time for cooking depends on the sun. Give the food plenty of time. Because the solar oven doesn't achieve burning temperatures, you can put the dish in and let it go while you work on other things.
  • Re-orient the oven about every 45 minutes towards the sun, so that the oven’s shadow is directly behind the stove, with the sun reflecting through the glass. Extra time will often make up for higher temperatures.

Important: If the food is not cooking (clouds appear or the sun goes down), the temperature can become a perfect temperature for pathogens to take over. Partially cooked foods should be removed and cooked in a nonsolar way (wood, gas, etc.)
