Countries such as Kenya, Rwanda, Nigeria, Chad, Algeria, Libya, Egypt, Sudan and many others on the African continent have such Ideal solar cooking conditions. It is possible to solar cook on the pacific shores of Chile, Peru and Costa Rica, as well as the deserts of Australia, Saudi Arabia and Iraq.
Solar ovens use solar energy—light and heat emitted from the sun—to cook food. They can also be used to pasteurize water or even sterilize instruments.
Solar ovens can reach temperatures comparable to those of traditional gas and electric ovens (in the region of 400 degrees F). A solar oven is just as easy as your oven in your indoor kitchen. Consider using dark-colored bakeware, which absorbs and retains heat better than light-colored pans and casseroles.
Use a dark-colored pot to absorb more sunlight because the reflectivity of the oven interior will increase the solar energy in the cooking vessel. Paint the oven's interior all black using high-temperature BBQ paint so it absorbs and retains heat so much better by conduction.
Reflectors: Cut some cardboard, glue aluminum foil to each piece (shiny side out), and tape the reflectors together and onto the oven. You can boost the heat quite a bit with a reflector, which increases the amount of total sunlight radiation that gets into the oven cavity.
Can you sterilize water in a solar oven? Yes. In all three types, water can be brought to a boil. A little-known fact, however, is that to make water safe to drink, it only has to be pasteurized, not sterilized.
The three most common types of solar cookers are box cookers, panel cookers, and parabolic cookers. Hundreds — if not thousands — of variations on these basic types exist. Evacuated tube cookers and trough cookers are two lesser known styles of cooker design.
Solar technologies can harness this energy for a variety of uses, including generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use.
Above the earth's atmosphere, solar radiation has an intensity of approximately 1380 watts per square meter (W/m2). This value is known as the Solar Constant. At our latitude, the value at the surface is approximately 1000 W/m2 on a clear day at solar noon in the summer months.
Solar cooking tips:This recipe takes about 20 minutes when prepared in a conventional oven heated to 450 degrees Fahrenheit. So, expect it to take about an hour in your solar oven. Refocusing the oven every 30 minutes to follow the sun's rays will help you cut cooking time for an even speedier snack.
Set the solar oven in direct sunlight and make sure the foil on the flap is reflecting light into the box. Cook the marshmallows until they're squishy (approximately 30 minutes).
Solar panel efficiencyA higher efficiency rating is better, because it means that your solar panel is able to convert more of the sunlight it captures into electricity. The best solar panels available on the market today are SunPower's A-Series Residential Solar Panels, which are 22.8% efficient at their maximum.
The biggest disadvantage of using a solar cooker is that it is dependent on sunlight for cooking. As a result, you cannot cook using a solar cooker at night. Besides, rain, low sunlight penetration, cloudy weather, etc. also serve as impediment to cooking on a solar cooker.
Solar cookers really do work. Many families in the world use solar cookers exclusively. Solar cookers allow you to prepare food when there is a power outage even if it is not a bright sunny day. Also, they can get hot enough to sterilize foods and drinking water.

A solar cooker uses the energy of direct sunlight to heat, cook, bake or pasteurize food or drink. It only works when the sun shines, so solar cooking can never be a stand-alone technology.
Can I use a SUN OVEN® in the winter? Yes, a SUN OVEN® can be used on a clear winter day. The most important factor in using a SUN OVEN® is the brightness of the sun, not the outside air temperature. Often, a 40-degree, clear, low-humidity day will allow food to cook faster than a 100-degree day with high humidity.
Prop the foil-lined rectangle on the lid open and hold it open using metal wire or bamboo sticks placed at the corners. Place your food, in cookware, inside the shoebox and put the lid on top. Position your solar cooker where it will get the most exposure to sunlight.

In the solar oven, the light energy from the sun is transferred into heat energy when it strikes the black construction paper. The now warm object reradiates the energy it received from the sun into the surrounding environment in the form of infrared (heat) radiation.
Your oven is ready! You can try heating s'mores, English muffin pizzas, or hot dogs, or even try baking cookies or biscuits. Test how hot your oven can get using a simple oven thermometer!
