“…According to his results, 16.8 million tons of firewood can be saved and the emission of 38.4 million tons of CO2 per year can also be prevented. Hernandez and Huelsz [16] presented the optimization of optogeometrical design of a solar oven for the intertropical zone. It was found that the constructed oven can save a potential quantity of wood of 850 kg per year.…”

Limited fossil resources and environmental problems imply that development of solar thermal appliances will play major role in incoming years, especially to meeting domestic energy requirements. The cooking energy demand, which is the largest primary energy-consuming sector and, are continuously increasing. This research paper deal with the temperatures and efficiency mapping of a realized parabolic solar cooker tested in Saharan region of Ghardaîa (Algeria) climatic conditions. Using Black body temperature equation's based on Stefan-Boltzmann law, maps for focal areas receiver temperatures of the cooker are obtained by converting obtained results from optical simulation to thermal values. Several maps are generated through present study for both summer and winter with clear and cloud skies. It was found that cooker temperature values obtained during experimentations and that estimated using the proposed approach has good agreement. The rate of using the cooker from Northern to Southern regions of the country was not identical. For cloudy skies, the major area of the country is favorable for the use of the cooker during winter months. For clear skies, the mapping results indicate that the realized cooker is efficient in all the country throughout the summer season with temperatures exceeding 110 °C. The use of the cooker will be reduced by going in South to North regions during the winter months, depending on the amount of solar radiations received.

“…Some of the tests conducted earlier in 1978 have been summarized by Bowman [4]. Ahmad [5], Al Towaie [6], Amer [1], Avala [7], El Reidy [8], G Hernandez [9] also have conducted tests on solar cookers and concluded that solar ovens are environmentally friendly and cost effective devices for harnessing solar energy. Field testing has been conducted by Herliyani [10] in order to encourage the usage of solar ovens in Indonesia.…”

Solar cookers or solar ovens are devices that use sunlight as their energy source. These devices are primarily used for heating purposes. A double layer quintuplet solar oven was researched; the objectives were to study performances of the solar oven in harvesting sunlight to reach the highest temperature and heat storage, and to compare theoretical models against actual experimental data. The solar oven was fabricated using glass panels and supported by a trolley for mobility. The solar oven in-field testing was set at 08:00 to 18:00 hours to ensure maximum exposure to daytime direct sunlight, thus maximum heat captured. A temperature sensor (thermocouple) was used to measure the temperature changes inside the oven. A XR440 Pocket Logger was connected to the sensor to record the measured temperature on an hourly basis. The experimental data were then collated and presented in a graphical format to visualize the trend. A numerical analysis based on theoretical modeling was done to compare with the experimental data which was affected by actual weather conditions. The experimental data showed that the maximum temperature captured inside the solar oven was 80°C. In principle, the temperature inside the solar oven will increase proportionately to the increments of the solar radiation from sunlight. This experimental study concluded that the maximum heat gained by this double layer quintuplet solar oven was 80°C or at solar irradiance value of 578.04W/m2. This experimental irradiance value when compared against the irradiance value calculated based on the theoretical model shows a variance of 8.44%. This parametric research study is worth exploring further as a research frontier in alternative sustainable energy in Malaysia. Similar research by other scholars reported that the solar oven will function effectively as a cooking device if the solar irradiance heat generated inside it is more than 800W/m2. With this finding, a further enhancement can be made to the oven design to improve the maximum heat gain.
