The Solar Box is a square, usually wooden, well-insulated crate/box with a lid. The inside of the box and lid are lined with aluminium foil.
The bottom (where the pan sits) is painted flat black. The box is sealed hermetically with a glass lid. A temperature of approx. 140˚C can be reached.
Mostly all types of food can be prepared in the solar box, but it is approx. 3 to 4 times more expensive than the CooKit. It is often too expensive for the very low-income target group. However, the box is more durable. By initially starting to cook with the CooKit, women could save for a Solar Box.
All cooking equipment, including the Solar Box, is produced locally.
Other Solar boxes
The Togo Tilé project in Mali, is experimenting with a cardboard box. This box was designed by Piet Sluimer, a member of our work group ISC/R.E.T. (Renewable Energy Technology) for Households. This cheaper and lighter box also reaches a temperature of ± 140°C and works perfectly. The Togo Tilé project currently looks at the box’s durability when used in the African climate as well as into the possibilities for local production.
