The use of solar energy for baking, heating or drying represents a sustainable way of solar energy
applications with negligible negative effects. Solar oven is an alternative to conventional oven that rely
heavily on coal and wood or Electric oven that uses the power from the National grid of which the end
users have little or no control. Since the Solar oven uses no fuel and it cost nothing to run, it use are
widely promoted especially in situations where minimum fuel consumption or fire risks are considered
highly important. As useful as the Solar Oven proved, it major setback in the area of applications has
been its future sustainability. For the use of Solar Oven/Cookers to be sustained in the future, the design
and development of solar oven must rely on sound analytical tools. Therefore, this work focused on the
design and development of the solar oven. To test the performance of the Small Solar Oven a 5000cm3
beaker of water was put into the Oven and the temperature of the water was found to reach 810C after
about 3hrs under an average ambient temperature of 300C. On no load test, the oven reached a
maximum temperature of 112oC in 6hrs. In order to carry out the parametric studies and improve the
performance of the Solar Oven, Mathematical models were developed and solved by using
Characteristics-Based Split (CBS) Finite Element Method. The Model results were compared with the
Experimental results and a good agreement ware found between the two results
