Types of solar cookers
There are several different types of solar cookers available, each with its own unique design and functionality. These cookers harness the power of the sun to cook food, making them an eco-friendly and sustainable alternative to traditional cooking methods. Here are some of the most common types of solar cookers:
1. Box cookers
Box cookers are made of an insulated box with a transparent lid, usually made of glass or plastic. The box is painted black on the inside to absorb and retain heat. The lid allows sunlight to enter and the heat gets trapped inside, creating an oven-like environment. Box cookers are versatile and can be used for baking, boiling, and roasting.
2. Panel cookers
Panel cookers consist of a series of reflective panels that focus sunlight onto a cooking pot or tray. The panels are usually made of metal or cardboard covered with reflective material. The pot or tray is placed in the focal point of the panels, where the concentrated sunlight heats it. Panel cookers are lightweight and portable, making them ideal for camping or outdoor activities.
3. Parabolic cookers
Parabolic cookers use a curved, reflective surface to concentrate sunlight onto a single focal point. The cookware is placed at the focal point, where it gets heated by the intense solar energy. Parabolic cookers can reach high temperatures quickly and are ideal for stir-frying, grilling, and frying.
