The diagram shows how meal is cooked by solar box oven.
Overall, it is evident that the process compromises six distinct stages, beginning with painting a cardboard box and culminating in exposing the entire setup to the sun.
Initially, the cardboard box is painted black, with the pot filling with vegetables. Having been placed, it can move on to the next stage where the pot is put into the cardboard box. Before rolling newspaper, grass, or sawdust at the bottom of a large box, the cardboard box is placed into the large box.
After setting the large box, at the top of the box is covered with a foil and a glass lid is placed on the top. Finally, whole construction is put under direct sunlight, with a minimum temperature of 82 degrees. The food is cooked as the black color absorbs sunlight and converts it into a heat.
