Institutional Solar Thermal Cooking Stove

Identification

Designed for institutional users such as rural and peri-urban schools in Kenya, the Solar Thermal Cooking Stove system delivers a solution to both cook and heat water without using any firewood.

Addressing the lack of electricity, reliable supply and sustainable energy sources, this solution developed a tailor-made cooking system with the same capacity as the wood fuel stoves, using only the sun's rays as fuel. Apart from a minor demand of power for solar tracking, sustained by a small PV panel, the system requires no electricity or other fuel, storing heat for morning cooking. The institutional solar stove consists of a number of solar collectors (2 to 6, depending on application type, location and need for input heat), a heat storage component and an adequate number of cooking units, for school and larger-scale cooking - referred to as sufuria heaters. The heat is transferred between each component by means of thermosiphons, which are tubes, filled with water and at a slight sub-pressure. The solution helps to reduce cooking cost, deforestation, indoor pollution and improve the workplace environment for the cooks.
