Abstract

A study was carried out to design, construct and test the performance of the angular reflective panel solar cooker. The reason study on solar cooker was conducted is because Malaysia receives abundant solar radiation throughout the year which is important for solar cooking. In addition to that, solar cooker is also seen as being able to provide a healthier and environmental friendlier alternative to cooking as oppose to cooking using firewood which is still practice by some rural communities. The design of the solar cooker was done with the aid of computer-aided design programs. The solar cooker was constructed from stainless steel with the aid of templates made with the aid of the computer-aided design programs. The performance test was done according to American Society of Agricultural Engineers' standard of testing and reporting solar cooker performance. In addition, test on the effect of the solar cooker under different configuration and the cooking performance of the solar cooker was also carried out. Test result according to the American Society of Agricultural Engineers' standard shows that the solar cooker lack proper insulation as the rate of heat loss was found to be high, viz 4.04 W/°C. The lack of proper insulation would dampen the solar cooker's performance especially when slow cooking, viz cooking at consistent temperature over a long period of time, is required. The test of the solar cooker under different configuration showed that the rate of heat gain would decrease with the increase in load volume. The test also concluded that out of all the cooking vessels used, the beaker provided the best performance. This is because the beaker allowed most of the wavelength that is emitted by the Sun to penetrate it thus heating the water directly. In terms of cooking performance of various foods, it was found that a meal of six dishes can be cooked within the 4h of the 1000 hr to 1400 hr solar time. Further improvement can still be made on the solar cooker especially in terms of its lack in proper insulation.
