How Does a Solar Cooker Work? How Does a Solar Cooker Work?
Solar cookers are solar powered, which means the energy required to work them is generated from the sun rather than through standard eletricity. Solar power is an eco-friendly option as well as a cost saver. Energy sourced from the sun is free. Solar-powered devices are fitted with solar panels that collect energy. Once the panels are charged, the device will work just as if it were plugged into an electrical outlet. However, solar cookers need constant contact with the sun to work effectively.
Solar Powered Cookers
Solar cookers are used outdoors because they depend on sunlight to maintain a constant heat. As the sun moves, it is necessary to move the cooker so that it's always in direct sunlight. Shadows can reduce the temperature of the cooker, and solar cookers don't hold their heat in the same way that a barbecue can. Constant energy is the key to keeping a solar cooker working to its full capacity.
Solar cookers work in a few ways, either by concentrating the sunlight and then dispersing the heat, or by trapping and circulating the heat like in a Dutch oven. For this method, you need a transparent cover so that the sun can penetrate through the top.
Another method is where the light is converted to heat. These cookers are usually blackened out. As black conducts heat, this method regulates heat adequately.
