“…Few solar cookers' studies assess the analysis of the local context: needs, habits, and available resources. Biermann reported the results of a 1‐year comparative field assessment of 7 different models of panel, box, and parabolic solar cookers, involving 66 households in study areas in the South Africa context. Wentzel and Pouris presented a work, which summarizes the findings of available impact and use rate studies related to solar cookers dissemination in DCs.…”

Design and performance evaluation of solar cookers for developing countries: The case of Mutoyi, Burundi

Summary Here, we propose an approach for supporting the design and performance evaluation phase of solar cooking technologies, to assess their eventual appropriateness for remote rural contexts, before proposing them for local field tests. The approach is based on (1) local context description and analysis, (2) design and construction of the solar cookers, and (3) thermodynamic performance evaluation. We used the approach to analyse 3 cookers for the area of Mutoyi, Burundi: a parabolic, a panel, and a box cooker. From phases 1 and 2, only panel and box cookers emerged as the technically viable solutions: They were sized, optimized, built, and tested. In phase 3, the thermodynamic evaluation indicated that the box cooker is inappropriate, since water does not reach high enough temperature. Instead, the panel cooker shows a Standardized Cooking Power of 46.85 W and a stagnation temperature higher than 75°C, which is able to bring the water to the boil when the environmental temperature is higher than 25°C. The thermal efficiency of the cooker resulted equal to 8.13%, while the mean integral temperature Tm remained around 60°C for all the lab test replicates, higher than the minimum internal temperature to cook legumes. The results of the procedure applied to the case study indicate that the panel cooker can be proposed for local field tests with local food and cooking practices, for assessing its final appropriateness on the field.

“…The overall efficiency of the novel solar cooker was found to be 29.5%. Ibrahim and El-Reidy [9] designed a box-type solar cooker and evaluated its performance for use in the Egyptian climate where they found that a good meal for four people could be cooked in 3-4 h. Biermann et al [15] performed 1-year comparative tests on seven different types of solar cookers in South Africa. Measurements revealed an overall fuel saving of 38%.…”

SUMMARYThe performance of a low-cost compound box-reflector solar cooker designed and constructed by the department of Mechanical Engineering, at the University of Zimbabwe, was investigated and evaluated using a microcontroller-based measurement system over a period of 3 months. Solar radiation and temperature measurements are sent directly to the computer for monitoring and subsequent analysis using a spreadsheet program. The system is connected to the computer through the RS232 port. Temperature was measured by LM335 temperature sensors, whereas solar radiation was measured by a Kipp & Zonen CM3 thermopile-based pyranometer that was initially calibrated against the Eppley Precision Spectral Pyranometer. Peak temperatures of about 901C for the food can be attained in about 5 h on a clear day in Bindura, Zimbabwe (181S, 311E). A standardized cooking power of 11 W and an overall efficiency of 15% were found for this cooker.

“…Ahmad [5] found that some families in Gujarat, India chose not to use solar cookers because they did not have suitable space in their living area, other families could not adjust to the routine of using a solar cooker, and others still were simply not interested in using solar power. Additional studies have shown conflicting results concerning the implementation of solar cookers in different regions of Africa, primarily relating to acceptance of the technology and perceived ease of use [18][19][20].…”

Abstract:We explored repurposing discarded materials to construct simple, field expedient, solar heating devices capable of heating drinking water to water pasteurization temperatures. Results of different test configurations quickly constructed from junk material indicate important design parameters to include maximizing exposed container surface area and using transparent glass and dark absorbent material inside the solar heater box. The optimal configuration heated water to 69 °C in a few hours demonstrating that a field expedient, zero cost solar heater capable of pasteurizing water (65 °C) can be quickly assembled from discarded material. Translating these key design parameters, rather than the exact design itself, to people in developing countries via relief organizations could help improve drinking water quality, reduce respiratory distress from indoor biomass burning, and potentially reduce the time and household income devoted to acquiring traditional biomass fuels. Organizations that operate in austere or disaster prone regions where safe drinking water may be unavailable may also benefit from knowing these design principles.
