Parabolic solar cookers use a parabolic-shaped reflector to direct sunlight to a small area in order to generate heat for cooking. They are able to reach high temperatures, 350 °C (662 °F), which allows them to be used for grilling and frying. These temperatures are significantly higher than what can be reached by a solar box cookers or solar panel cookers and allow the cooking times on a parabolic cooker to be comparable to a conventional stove, such as an electrical or gas burner.

The amount of food being cooked and the way in which the heat is used is generally dictated by the size of parabolic dish. Smaller dishes, which are generally around one meter in diameter, are intended to heat a traditional size pot or pan much like how you would cook on a traditional cooktop. The larger dishes, which can be as wide as five meters in diameter, are generally not used to heat a pot or pan directly, but instead are used to create steam by directing sunlight onto pipes carrying water. The steam is directed to cooking surfaces in a kitchen and is regulated by valves in order to offer control to the chef.

Advantages and disadvantages


  • Cooking times are similar to a traditional stovetop
  • High temperatures allow for food to be fried and grilled


  • Requires periodic adjustment to refocus it as the sun moves or a mechanical solar tracking apparatus
  • Generally more expensive than panel and box cookers

What can you cook?

Parabolic solar cookers generally operate at very high temperatures so they are ideal for frying, grilling, and boiling food. You can also bake breads and other baked-goods in a parabolic cooker. While they don't easily offer slow-cooking capabilities, they can be paired with a retained-heat cooker to prepare foods which call for longer cooking times at lower temperatures, such rice, beans and many other foods.

Types of parabolic solar cookers


If you’re interested in a parabolic solar cooker for personal use, an approximately 1 square meter dish is an excellent choice. This size will allow you to cook for yourself and a small group of friends and family and can accommodate a larger group if simple technologies like heat-retention cooking are used to maximize the cooking power of the parabolic oven. A 1 meter dish is similar in size to a traditional barbeque so storage should not be too difficult.

Examples of personal parabolic cookers


Parabolic cookers offer advantages to box and panel cookers for individual consumers, but the technology is also well-suited to larger ovens on an institutional scale. Used slightly differently, larger parabolic cookers, which can reach up to five meters in diameter, are often used to focus sunlight on pipes carrying water. Rather than using the resulting heat to directly cook food, the heat turns the water into steam which is piped into a kitchen to heat a cooking surface. The steam is usually controlled by a valve in order to regulate heat during cooking.
