“…The use of solar energy is increasing with several pilot projects undergoing field tests in many developing countries (Fang and Li, 2013;Ondraczek, 2014;Otte, 2013). The solar energy devices such as solar cookers have been under demonstrations in Africa to solve part of environmental problems associated with firewood demand for cooking and for small-scale food processing in the rural areas.…”

“…Good quality road, ports, airports and railways infrastructure will play an important role in the facilitation and adoption of technological innovation. Otte (2013) argues that good road infrastructure is the key to the application and maintenance of solar cookers among the rural poor in Africa. Wickramasinghe (2011) analyzed road infrastructure in Sri Lanka and showed that the development and maintenance of road infrastructure in rural areas increased the efficient use of computers, internets, telecommunication technologies and networking facilities.…”

“…Ashraf Chaudhry et al (2009) argue that poor infrastructural development and lack of human capital development presents one of the biggest constraints to the installation, operation and maintenance of renewable energy products in Pakistan. Otte (2013) analyzed factors that may facilitate the adoption of solar cookers in developing countries and showed that poor infrastructure could be a hindrance in spreading the idea of solar cooking as well as limiting the opportunity of providing maintenance services in Tanzania. Moreover, it may be difficult to introduce renewable energy product such as solar cooker, where majority of the rural households use firewood, due to lack of awareness and benefits that may be associated with the solar cooking (Vanschoenwinkel et al, 2014).…”

In this study, a portable concentrating solar cooker was designed, fabricated and tested. A 90 cm standard old satellite dish was used as a concentrator. This standard satellite dish is available for all. So, it can motivate using solar energy in routine life. Temperature rise more than 40 °C in one kilogram of water observed only in fifteen minutes. It proves that the cooker is good enough for cooking and baking or being used as a water heater. A series of experiments were performed to study its performance. Based on those experiments, the solar cooker optical efficiency was estimated about 39.1%. Energy and exergy study were also performed. Results showed that its first law efficiency was about 32.6% and second law efficiency was 2.55%. These figures may prove its proficiency beside its simplicity.

“…Sunshine is free and always available, and if all the power from the sun can be harnessed, then all of the human energy need would be met. An important method in which direct energy from the sun is being used is through solar cooking technology, which ranges from very simple ones to very sophisticated ones in terms of technicalities [3].…”

Abstract:The continuous increase in global demand and cost of electricity are some of the reasons that solar cooking has received much attention recently. Another factor which has also contributed to the acceptance of solar cookers is global campaigns against actions that contribute to climate change. Various types of solar cookers are currently in existence, these are box, panel and parabolic cookers. Some solar cookers only function when the cooking section is placed under direct sunshine, while others have been modified to cook without directly exposing their cooking section to the sun. Most solar cookers face similar challenges, and these include, exposure of users to sun, inability to function at night or when there is no sunshine, low utilization efficiency and technical complexities. This report presents an indirect parabolic cooker that eliminates the identified solar cooker challenges. The cooker uses a parabolic reflector to focus the sun rays to a frustum shaped receiver that was placed at its focus. The cooker has an insulated cooking/heat storage tank which was separated from the dish and cavity receiver system. The heat transfer fluid was distributed through the system with the aid of high temperature flexible hoses. Several cooking tests including water boiling and pancake baking were done, an extensive analysis of cooking based on the international testing procedures for solar cookers was also carried out. This solar cooker had a utilization efficiency of 39%, an overall calculated exergy efficiency of 0.05% and an average characteristic boiling time of approximately 13 minutes/kg. The manufactured solar cooker in this study was used for family cooking.
