“…Solar energy is, among other sources, a potential substitute of wood in a large portion of the DCs: Solar cookers are thus considered as one of the possible options for solar energy exploitation . Comprehensive technical reviews of different solar cooker models have been made: Mirdha and Dhariwal investigated the optimal arrangements of booster mirrors in box cookers to define a particular design, which allows a cooker to be fixed facing south without the need of tracking during the cooking. Panwar et al developed a comprehensive review on classification, standard method for testing solar cookers, energy and exergy‐based approach for analysing the thermodynamic performance, and economic evolution of different types of solar cooker, especially box and parabolic cookers.…”

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.

Menipisnya persediaan energi yang berasal dari fosil seperti minyak bumi, batu bara dan gas alam mengharuskan masyarakat beralih menggunakan energi alternatif. Dalam hal ini, Kementrian ESDM menghimbau untuk mencari dan mengembangkan energi alternatif sebagai pengganti energi konvensional. Salah satu energi alternatif yang harus dikembangkan adalah energi surya. Salah satu penggunaan energi surya dapat diaplikasikan dalam proses memasak. Tujuan penelitian ini adalah untuk mengetahui perubahantemperatur tiap titik pengukuran pada box kolektor surya dan vessel saat proses charging dan discharging, mengetahui perbandingan temperatur vessel yang menggunakan lug dan tidak menggunakan lug pada proses charging dan discharging, serta untuk mengetahui efesiensi termal box kolektor surya pada proses charging dan silinder isolator pada proses discharging dalam menjaga temperatur nasi. Pengujian pada proses charging dilakukan dengan menggunakan box kolektor berukuran 120 × 120 (cm) dan pada proses discharging menggunakan silinder isolator berukuran 30 × 45 (cm). Pada proses charging dilakukan pada pukul 10:00-16:00 WIB dan proses discharging pukul 16:00-09:00 WIB. Temperatur rata-rata proses charging untuk vessel menggunakan lug adalah 78,81 oC dan tidak menggunakan lug adalah 73,10 oC. Hal ini terjadi karena pada vessel yang menggunakan lug dapat menyerap energi panas dari sisi bawah vessel. Sedangkan efesiensi yang diperoleh box kolektor surya tertinggi adalah pada proses charging 41,54 % namun belum mampu meleburkan PCM yang memiliki temperatur lebur 120 oC karena temperatur maksimal yang mampu ditangkap box kolektor adalah 99,52 oC. The depletion of energy supplies derived from fossils such as oil, coal and natural gas requires people to switch to use alternative energy. In this case, the Ministry of Energy and Mineral Resources calls for seeking and developing alternative energy as a replacement for conventional energy. One of alternative energy which must be developed is solar energy. Solar energy can be applied in cooking process. The purposes of this study were to determine the change in temperature of each measurement point in solar collector box and vessel during the charging and discharging process; to compare the temperature vessel using lug and not using lug on the charging and discharging process; and to determine thermal efficiency of solar collector box during the charging process and cylinder insulator in discharging process for maintaining the temperature of rice. Testing on the charging process was conducted by using collector box of 120 × 120 (cm) and in discharging process by using an insulator cylinder of 30 × 45 (cm). The charging process was done at 10:00 - 16:00 WIB and discharging process from 16:00 to 09:00 WIB. The average temperature of the charging process for vessels using lug was 78.81oC and not using lug was 73.10oC. This happens because the vessel using lug could absorb heat energy from the bottom side of the vessel. While the highest efficiency obtained by the solar collector box was on the charging process, i.e. 41.54% but had not been able to melt PCM which has melting temperature of 120oC because the maximum temperature that could be captured by the collector box was 99.52oC.

“…A number of solar cookers have been designed and studied by different authors (Vishaya et al 1985;Nahar 1990;Grupp, Montagne, and Wackernagel 1991;El-Sebaii and Ibrahim 2005;Negi and Purohit 2005;Nandwani 2007;Kumar 2008;Kumar et al 2008;Mirdha and Dhariwal 2008;Harmim et al 2010). The values of bare plate temperatures, ambient temperatures and insolations, which were observed during stagnation test by the authors for their systems, are listed in Table 3.…”

“…Solar cooking is a low-priced, smoke-free solution for many problems that have arisen and are increasing day-by-day because of the consumption of solid fuels. Although, several solar cookers have been designed, developed and studied by many authors (Vishaya et al 1985;Nahar 1990;Grupp, Montagne, and Wackernagel 1991;Negi and Purohit 2005;Nandwani 2007; Kumar et al 2008;Mirdha and Dhariwal 2008;Harmim et al 2010), yet possibilities for improvement in the thermal performance of solar cookers that are subjected to the design improvements and the selection of more efficient materials to develop different components of the system are still open.…”

This paper presents the fabrication details and on-field experimental studies of two novel solar cookers, suitable for cooking requirements of small families; these are named as small family solar cookers (SFSC-1 and SFSC-2). Small size, good thermal performance, light weight, low-cost and short payback periods are some important features of these cookers. The values of some essential thermal performance parameters, first figure of merit (F 1 ), second figure of merit (F 2 ) and standard cooking power suggested by Bureau of Indian Standards and International Standard for box-type solar cookers, have been evaluated by experimental studies and found to be 0.116 • C m 2 /W, 0.466, 30 W and 0.118 • C m 2 /W, 0.488, 50 W for SFSC-1 and SFSC-2, respectively. A comparative analysis of the thermal performances of SFSCs with the solar cookers, developed by many authors, has also been presented here. The payback periods with respect to different cooking fuels for SFSCs have been found to be reasonably short.
