Abstract:

Food, cloth and shelter are three basic necessities of life. Food can be regarded as essential component for growth and survival of human being. So, the source of cooking is one of the most important things in our daily lives. There are various cooking sources of energy like kerosene, LPG, Firewood and Renewable sources etc. and one of them is solar cooking which is a renewable source of energy. Solar cooks are limited by the fact that cooking can only take place during daytime. If a thermal energy storage system is provided to solar cookers, food can be cooked during hours of evening or night. In the last few decades, the cooking sector has used various solar cookers, including the box type solar cooker, flat plate type solar cooker, parabolic dish type solar cooker, evacuated tube type solar cooker and Scheffler dish solar cooker with sensible heat, latent heat and Combined heat storage technologies for the solar cooker. As a result, this paper summarizes the investigation and analysis of the available thermal energy storage materials (sensible heat, latent heat and combined heat storage materials) to store heat during the daytime and use it for purposes other than daytime hours for use in solar cooking application. The current study also compares the Sensible heat, Latent heat and combined heat storage systems for cooking.

Abstract:

Energy demand is increasing due to population increment and industrialization. To meet this energy demand, technologies that use renewable energy such as solar energy are being developed. A parabolic solar cooker is one of the main solar cookers, which can cook food and boil water at a high temperature within a short period. This study aimed to design, construct, and evaluate the performance of the constructed parabolic solar cookers. Moreover, this study aimed to compare the constructed cooker with firewood, charcoal, kerosene, and electricity in terms of cooking time and energy cost. The cooker was constructed using different materials such as old satellite dishes, tyres, steel, and aluminum foil. The aperture diameter, aperture area, receiver diameter, receiver area, depth of the parabola, focal length, rim angle, circumference of the circle, surface area, length of the circumference, and concentration of the cooker were 1.8 m, 2.54 m2, 0.16 m, 0.02 m2, 0.3 m, 0.67 m, 67.38°, 5.76 m, 2.81 m2, 5.76 m, and 123.46, respectively. The cooker can track the sun from north to south and from east to west. The performance of the cooker was evaluated by calculating the efficiency and power. The output energy, input energy, and average upcoming solar radiation of the constructed parabolic solar cooker were 0.182 kW/m2, 1.691 kW/m2, and 0.665 kW/m2, respectively. The efficiency and power of the cooker were 10.75% and 0.3 kW/hr, respectively. The constructed parabolic solar cooker relatively showed better performance in cooking different foods. A family, which has five members, was considered to compare the constructed cooker with other fuels in terms of energy cost of cooking. Since the parabolic solar cooker does not have any energy cost, it can save the energy cost of cooking foods. Therefore, parabolic solar cookers have a great advantage for developing countries including Ethiopia.

Abstract:

The most common type of energy used is firewood. In some Sub Saharan countries, up to 90% of total energy use is from firewood. The consumption of wood fuel is in some countries as high as twice the sustainable yield, something that has led to environ-mental degradation due to deforestation and scarci-ty of firewood. The use of fossil fuels such as kerosene and LPG for cooking is expensive. Solar energy is a non-consumptive and non-polluting fuel. It can help alleviate the problem of insecurity of cooking energy, which is the major domestic energy requirement. Several attempts have been made to introduce solar cookers in different coun-tries and have achieved variable successes. There are still critical issues yet to be resolved in order to make that technology acceptable for wider dissemi-nation. They include getting the most appropriate types of solar cookers for specific locations, opti-mum size/capacity, types of materials to be used, optimal design and affordable cost. In an attempt to resolve these issues, a comprehensive study involv-ing theoretical review, development work, experi-mental testing and evaluation of solar cookers was conducted for several years on six different types of solar cookers. The cookers are the ‘SunStove’ box cooker, wooden box cooker, panel cooker, reflector cooker with unpolished aluminium reflectors, reflec-tor cooker with polished aluminium reflectors and reflector cooker with glass mirror reflectors. This paper presents the results of the study. Results obtained indicate that many of the cookers could be used to cook food for households in areas with medium and high insolation, with appropriate selec-tion of the type and specification of the cookers. The specification should be based on the measured inso-lation data of the location indication of the direct and diffuse components. As a guiding tool, reflector cookers offer best comparative performance in areas with longest durations of clear sky (greatest direct beam), panel and collector cookers under moderate cloudy conditions and box cookers under very cloudy conditions.

Abstract:

Single Point Incremental Forming is a new process, which has been developed to make both Rapid Prototyped products and low volume product batches from Sheet Metal. This paper presents a case study of the manufacture of a solar cooker cavity for developing country applications. In the first instance the request was for a rapid prototype, which quickly evolved into a request for low volume production of solar cookers for the developing country market. The paper describes the manufacture of the solar cooker cavity, and shows how the possibility of manufacturing part of the solar cooker, by Single Point Incremental Forming, gives rise to the possibility of manufacturing other parts for the solar cooker less expensively.

Abstract:

An inclined box-type solar cooker employing tracking reflectors with dimensions 700mm x 440mm x 280mm, has been successfully designed and fabricated. The detachable reflectors, which were mounted on the box cooker, were suitably positioned in an east-west configuration on an inclined framework. This automatically tracks the apparent motion of the sun within 15 minutes time interval so as to align with the earthâ€™s rotation when displayed under the sun. Thermal performance of the inclined box-type solar cooker has also been compared with that of a conventional box-type solar cooker whose dimensions and make are identical to the inclined box cooker. Testing of the tracking box type solar cooker has been carried out with load and without load conditions at Federal University of Technology Owerri, Imo State, located at Latitude 5oN, Longitude 7oE, Altitude 156m (Altitude 511ft) and 12km south of Owerri capital territory. Experimental results obtained from the field test show that the inclined box-type solar cooker with tracking reflectors attained temperature of 94oC, with efficiency of 93% and boiled water for 1hour 28 minutes. The conventional box-type solar cooker attained a temperature of 91oC, with efficiency of 90.9% and boiled water for 1hour 36 minutes. The tracking box cooker was found to be more efficient and effective than the conventional box cooker. Meteorological variables like Air Temperature, Irradiance, Relative Humidity and Wind speed were also obtained to investigate their effects on the performance of the box cookers.

Abstract:

Solar cookers can greatly reduce the overall carbon footprint of the cooking done in India. In the present work a funnel-type solar cooker is designed using cardboard. After making the solar cooker it is then analyzed on the various performance metrics namely the figures of merit, efficiency value and Cooker Opto–thermal Ratio (COR) which are dependent parameters. Paraffin wax which is a phase change material (PCM) is also incorporated in the testing process to evaluate the overall improvement in the thermal efficiency of the solar cooker. The time taken to break is also calculated. The experimental results show that the solar cooker is capable of reaching a temperature of 125 °C. From the results it can also be seen that using paraffin wax also offers significant improvement in the overall thermal efficiency. The results are tested on various parts of India considering the major cities such as Chennai, Trivandrum, Kanpur and Delhi with the ANN model, which is a deep learning model. The advantage of this model is that it can forecast and estimate the temperature of the absorber plate and water from weather forecasting data which is used to calculate F1 and F2 metrics for the performance of the solar cooker. For all the cities, the model’s R2 value is greater than 99% and RMSE values are small.

Abstract:

The failure of a pane of glass from a solar box cooker made and used in Sabana Grande, Nicaragua, was analyzed to determine the cause of failure and to recommend possible solutions. Background research into solar box cookers, the environment in which the failure occurred, characteristics of glass and wood, methods of fractography, and glass cutting tools and methods was carried out. The type of glass used in the solar cooker was unknown, so the observable physical properties, an energy dispersive spectroscopic scan, and thermal analysis of the glass were used to identify the glass as soda-lime glass. The properties of the glass, the conditions of use, and an analysis of the fracture pattern and fracture surfaces were used to determine that the glass had been weakened by cutting processes and that the fracture occurred as a result of thermal stresses. Several recommendations were presented including altering the design of the solar cooker to provide more clearance for the glass panels, incorporating the use of improved glass cutting techniques and sanding the edges of the glass.

Abstract This work shows the results and evaluation of a solar cooker box-type by using CFD. The values indicate where the highest temperature values happen inside the solar cooker. Also, values for density and airspeed were obtained. These results show where and how density and airspeed have the most important values during the water heating process. The effects of convection as a consequence of the temperature difference can guide possible improvements in future designs of solar cookers since if geometric shapes are used that take advantage of this heat transfer mechanism, the solar heating process can be better.

Abstract:

This paper presents the feasibility of using solar photovoltaics (Solar PV) as the energy source for cooking with special focus on the loss mechanisms and possible remedial measures. If the heat loss is minimized, to reduce the temperature losses, it is possible to cook with a low power source less than 500 W. A slogan has been adopted by the researchers—‘It is temperature that cooks food not heat’, meaning that it is not the flow of energy that cooks food, but rather, that food is cooked when held at a key temperature for a time. The slogan draws attention to the core concept that if heat loss is minimized, maintaining the temperature inside the cooker and the cooking pan, then the cooking process becomes very energy efficient. The paper considers ways to maintain temperature, but with due reference to the ‘art of cooking’, those all-important cultural processes that determine how meals are made. A prototype solar home system e-cooker was designed, fabricated and tested for cooking different foods in Bangladesh. Experimental results are presented to show that cooking is possible using much less power and energy than is commonly thought. A cost analysis is also presented to show that such a cooker can be cost effective in off-grid areas if connected to a properly designed Solar Home System.

Abstract:

The objective of the present research work is to design user friendly solar cooker which can be commercialized too. This cooker is designed, developed, and tested in our laboratory. The basic principle is to incorporate heating into material by photovoltaic effect and thermal treatment. Different temperatures inside the solar cooker were measured and profile of solar cooker was studied for several days during April, May, and June 2012. It is observed that the designed cooker needs the boosting of only 30 watt power which is generated by a small solar panel connected with it. Heater connected with it can be powered by a solar panel of 75 watt. This boosting can reduce the cooking time. Different recipes were prepared to test its actual performance.

Abstract:

In this paper, the potential use and effectiveness of paraffin wax in a new solar cooker was experimentally investigated during daylight and late evening hours. For these experiments, a cooker having an inner reflecting surface was designed, constructed by filling paraffin wax and metal shavings. The side- and sub-surface temperatures of the paraffin wax in the cooker are measured in the summer months of June and July. The thermal efficiency of the cooker was tested on different conditions. The results show that the optimum angle of the outer reflector is 30?. Here, the peak temperature of the paraffin wax in the solar cooker was 83.4 ?C. The average solar radiation reflected makes a contribution of 9.26% to the temperature of paraffin wax with the outer reflector. The solar cooker with the outer reflector angle of 30? receives also reflected radiation from the inner reflectors. Besides, the heating time is decreased to approximately 1 hour. The designed solar cooker can be effectively used with 30.3% daily thermal efficiency and paraffin wax due to the amount of energy stored.

Abstract:

Sugar alcohols have interesting thermodynamic properties that make them good options as heat storage materials (HSMs) to be used in solar cookers. Among sugar alcohols, xylitol is affected by severe supercooling that can significantly alter its usefulness in thermal energy storage (TES) systems. To overcome the supercooling issue, in this work the thermal behavior of a xylitol-based TES installed in a portable solar box cooker was investigated experimentally. The solar cooker has a 4.08 concentration ratio and the TES is a double-pot system filled with 2.5 kg of commercial-grade xylitol. The TES includes a manual mixing device that can be used to trigger the nucleation of xylitol. The effectiveness of the TES system with and without triggering was assessed through several outdoor tests, divided into heating and cooling phases, using silicone oil as absorbing media. It was found that the average load cooling time, in the temperature range of the test fluid from 110 to 80 °C, increased by about 346% when the solar cooker was equipped with the xylitol-triggered TES. The mixing device can therefore be considered an effective solution for regarding xylitol as an actual and performing phase change material.

Abstract:

In this paper, a line focus solar cooker with deflection trough concentrators and heat pipe was for Tibet area successfully developed. The designed cooker met the demands of indoor use, miniaturization and improved the power and temperature of current solar cooker. It included two key parts: array of deflection trough concentrators and heat pipe. Firstly, the structure of the solar cooker was described, especially the improvement of the structure of the heat pipe. The condensing section of the heat pipe was designed to simplify the process of heat transfer, reduce the heat loss and improve the heat efficiency. Secondly, the mirror array of the deflection trough concentrators was tested experimentally. Meanwhile, the overall performance of the solar cooker was also estimated. Simultaneously, the solar radiation flux at the focal spot was improved. With the temperature of the condensing section of the heat pipe increasing, the power of the cooker was amplified. Finally, the data of the experiment was analyzed. The result showed that under the conditions of Nanjing, the power of the solar cooker was enhanced and it could reach 1200W. The temperature tested in the experiment reached the desired temperature, which maximum value was 214, so it will work well in Tibet.

Abstract:

Along with the development of technology, the need for fossil energy for cooking purposes using conventional stoves is increasing. The limitations of fossil energy reserves that cannot be renewed have resulted in an energy crisis starting to hit. Solar energy is an energy source that is environmentally friendly and available free of charge. Solar energy is utilized using the system. Concentrating solar power (CSP) focuses solar radiation to a point to get a higher temperature. This type of box-type solar cooker has a long history dating back to the 18th century when Nicholas-de-Saussure first made this type of solar cooker. A parabolic solar cooker is a solar-powered stove that uses reflections from the sun's radiation which is concentrated directly on the pan. A trough solar cooker collects sunlight and reflects it to a focal point using a reflective film. A box-type solar cooker has an important part between the reflectors which use aluminum foil with a diameter of 41 cm and a thickness of 0.2 mm. The collector was made of brass copper for cooking with a diameter of 41 cm and a thickness of 0.2 mm. The parabolic type of solar cooker has important parts, including a collector that uses a parabola with a diameter of 140 cm and a depth of 40 cm and a reflector that uses a reflective film with an emissivity value of 0.91. The trough-type solar cooker performs better than the box and parabola types because it has a higher temperature where the ambient temperature is 25.5 ℃, the focal point temperature is 164℃, and the load temperature is 163℃.

Abstract:

The main objective of our project is to conserve the available solar energy and improve its utilization with the help of phase change material; here we have absorbed solar energy to prepare food especially for cooking rice, boiling potatoes and eggs. The use of PCM in the solar cooker has improved its efficiency over conventional solar cooker and cooking food hot in off sunshine hours. It is being eco-friendly and other than that it save fuel, gas, coal which are exhaustible source of energy. In the present article some of different phase change materials are studied for solar cooking and among them Coconut Oil (commercial grade) is found to be a good latent heat storage which is experimentally tested in a simple box type solar cooker and the comparison is made with and without PCM.Key word: solar cooker, coconut oil, concentrating lens, phase change materials.

Abstract:

Solar cooking finds a major application in rural areas of Uttarakhand, India, yet its utilization is still limited due to certain limitation such as intermittent nature of solar radiations. This drawback limits solar cooker in becoming a viable alternate solution of LPG and other pollution causing resources such as wood. In order to cater this problem a numerical analysis of box type solar cooker with storage is carried out. The energy stored in the storage material will keep the cooker warm up to the time when food is consumed. Charging and discharging time analysis is performed in with an aim to understand the effect of storage on solar cooker. Heating and cooling characteristic time are being evaluated and analysed with storage. Thermal performance of box type solar cooker is measured in terms of figures of merit according to BIS standards. The effect of storage has also been analysed in terms of charging and discharging time and first figure of merit of box type solar cooker.it has been observed that during discharging the heat is stored for more duration as compared to the charging time as discharge time is approx. 4-5 hours while charging time for the same amount of insolation is around 3-4 hours.

Abstract:

Abstract Solar box cookers draw attention of many researchers across the globe as a promising renewable energy application for cooking purposes. Compared to other types available in literature, solar box cookers are more in the centre of interest owing to their simple and low-cost design, emerging thermodynamic performance figures, high durability and reliable cooking processes without any risk of burning food. On the other hand, cooking power and overall thermal performance of solar box cookers are still somewhat challenging to compete with the conventional cooking systems for the climatic conditions with low solar radiation potential like the Black Sea Region of Turkey. Within the scope of this research, a novel solar box cooker is devised, fabricated and tested to overcome the said shortcomings of traditional solar box cookers through natural and recycled materials. Double-glazed structure having 16-mm-thick air between two 6-mm-thick thermally resistive clear glasses is considered for aperture glazing with an area of 0.16 m2. The oven area has a depth of 350 mm, and it is entirely painted matte black for maximum solar absorption. The oven body made of stainless steel sheets is encountered by a latent heat storage medium filled by natural beeswax product, waste of propolis. Propolis is a resinous mixture that is used for protection of beehives, from either climatic changes or diseases. Polyphenols rich in balsamic part of the structure is extracted by alcohol than used for many apitherapic purposes. The remaining pulp or waste is not considered. In this study, it is used as green chemistry agents. It is found that water temperature in the cooking pot is kept over 40°C till very late hours as a consequence of latent heat storage. First figure of merit is determined to be 0.08, and the thermal efficiency of the cooker varies from 7.47 to 4.54%.

Abstract:

Being one of the major energy consumers, cooking is a necessary part of daily life. Non renewable cooking fuel sources, such as wood or cow dung cause hazardous pollution and a poor ecosystem worldwide. Over the past few decades, solar-powered cooking has undergone numerous improvements. Solar cooking has been predominantly used as a substitute for reducing oil and gas dependence, increasing environmental sustainability, and reducing global warming threats. This paper talks about the recent development of the box-type solar cooker. The paper discusses the principles and classifications of various parameters that affect the performance, energy, and exergy related to the solar cooking system. In line with the sustainable development goals of the UN agenda 2030 and especially the heed to the accomplishment of SDG 7 and SDG 13, various economic factors, such as the payback period (PP), net present value (NPV), benefit–cost (B–C) ratios, internal rate of return (IRR), levelized cost of heat (LCOH), and levelized cost of cooking a meal (LCCM) have been discussed. The environmental analysis has also been presented to show the overall benefit of solar cooking. The review also focuses on the current development of a box-type solar cooker, its components, and its heat transfer characteristic. Various geometrical modifications, the use of reflectors, and transparent insulating materials that improve cooking have been discussed. The concept of energy storage in the form of Phase change material (Latent heat storage) with the latest studied designs improvements of solar cookers has been obtained to be efficient, which also help in late-evening cooking. It can be said that with better policy implications, the social and economic acceptability of the solar cooker can be achieved.

Abstract:

The e-cooking feasibility was evaluated for two of the main staple foods across rural Sub-Saharan Africa (rice and maize porridge) considering basic solar home systems (SHS) of 100–150 W and using inexpensive market available low-power DC cooking devices (rice cooker and slow cooker). The coverage of e-cooking necessities was spatially evaluated for the African continent considering households of two, five, and eight people. While households of two people were able to be covered >95% of the days, the increase in e-cooking necessities implied that only larger PV generators (150 W) located in high irradiation sites (>2400 kWh/m2/year) were able to fulfill e-cooking, even in scenarios of households of five and eight people. Furthermore, the economic cost and the greenhouse gases emission factor (GHG) of e-cooking via small SHS were evaluated and benchmarked against traditional technologies with wood and charcoal considering three-stone and improved stoves and liquefied petroleum gas (LPG) cookers. The GHG for e-cooking was 0.027–0.052 kgCO2eq./kg·meal, which was strikingly lower than the other technologies (0.502–2.42 kgCO2eq./kg·meal). The e-cooking cost was in the range of EUR 0.022–0.078 person/day, which was clearly lower than LPG and within the range of the cost of cooking with wood and charcoal (EUR 0.02–0.48 person/day). The results provided a novel insight regarding market available technologies with a potential of changing cooking conditions in this region.

Abstract:

Low-income sub-Saharan Africa (SSA) households rely on wood for cooking for the simple reason that it is the lowest cost cooking fuel. Thus, full attainment of Sustainable Development Goal 7 (SDG7) requires developing clean cooking technologies that are cheaper than wood cooking. This study provides a comparative marginal levelized cost of energy (MLCOE) analysis for wood cooking vs. innovative solar electric cooking technologies. The two key off-grid solar technologies evaluated are: (1) direct-use DC solar (DDS) electricity for cooking applications, and (2) high-cycle-life lithium titanate (LTO) batteries. MLCOE is reported in USD/kWh for energy delivered to cooked food. A low median MLCOE of USD 0.125/kWh is attained using DDS electricity which is output directly by a solar panel with little or no intervening electricity storage and few electricity conversion and control costs. DDS solar panel output has variable voltage and current that is managed by a specialized DDS cooker. LTO battery-regulated electricity has a median MLCOE of USD 0.24/kWh which declines to USD 0.16/kWh with electric pressure cooker use. The distributions of MLCOE for wood-based, DDS-electric, and LTO-electric cooking strongly overlap. The MLCOE cost model suggests specific means for modifying input costs, component lifetime, and system efficiency to improve solar MLCOE further relative to wood MLCOE.

Abstract This study aims to develop a homemade solar cooker to be used in teaching and learning Thermodynamics. The research was based on the Design and Development Research (DDR) approach using the ADDIE model as an instructional design framework. The survey method was used to gather information about the solar cooker usability. The sampling technique used in this study is a simple random sampling that involved 30 respondents consisting of physics trainee teachers who had taken the Thermodynamics course. The research instrument consisted of validation and survey forms that have been validated by experts (n = 2). The data obtained through survey questionnaires were descriptively analyzed by the mean values and standard deviations (sd). Findings showed that the usability of solar cooker as a teaching aid were high i.e. the usability perception (mean = 4.57, sd = 0.349), usefulness (mean = 4.58, sd = 0.373) and user satisfaction (mean = 4.47, sd = 0.459). The study shows that the solar cooker can be used by students to learn Thermodynamics. It is hoped that the findings of this study will relate to the necessity for teachers to develop homemade products that relate the concepts and theories of Physics with real life.

Abstract:

Cooking using biomass, which is commonly practiced in developing countries, causes rampant deforestation and exposure to emission. Hence, utilization of solar energy for cooking is a green solution. As solar radiation is not available at every hour of the day, thermal storage is essential for availing thermal energy at required time of use. Therefore, this work investigates the efficiency of solar cooker with parabolic concentrating collector integrated with thermal storage using 1D finite difference computational model. A cook stove on packed pebble bed thermal storage having 0.3 m diameter and 0.9 m height and a storage capacity of 40.1 MJ of energy during a clear day and 12.85 MJ energy was simulated for charging and discharging (cooking), under Addis Ababa climatic condition for days, with highest and lowest solar irradiance and thermal storage efficiency of 66.7%, cooker thermal efficiency of 45% during discharging of heat by forced convection, and 41% during discharging of heat by conduction, were obtained for the day with the highest solar irradiance. The overall efficiency of the cook stove with thermal storage was 30% and 22% for discharging by forced convection and conduction, respectively. For the day with lowest beam solar irradiance, the storage, thermal and overall efficiencies were 70.9%, 31.1% and 22.0%, respectively. Hence, it can be concluded that solar concentrating cookers with thermal storage can have an overall cooking efficiency between 22% and 30% on a clear sky day when the Sun is overhead in tropical areas.

Abstract:

In the remote northwestern Chinese province of Qinghai (Tibetan plateau), the Tibetan people struggle to gather yak dung, wood, straw, and other fuels for heating, boiling, and cooking—the basic necessities for survival. Over the past seven years, extreme cold (-35°C) and drought has had a significant effect on the environment, the Tibetan people, and the livestock and crops upon which these people depend. The environment has become increasingly denuded and many Tibetans, both farmers and herders, are caught in a vicious cycle of destitution. The use of solar cookers as a partial substitute for dung, wood, bushes and straw has helped alleviate this cycle. This paper reports on the accrued benefits to remote Tibetan communities following a program of solar cooker introduction to 48 such recipient communities. Work carried out in 2003 primarily by Tibetan students studying in an English Training Program, at the Qinghai Nationalities Teacher's College, Qinghai Normal University, Xining City, PRC (supported by the Canada Fund) combined with observations over three visits to the region in 2003 and 2004 are discussed.

Abstract:

Use of latent heat storage system using Phase Change Materials (PCM) is an effective way of storing thermal energy and has several advantages like high storage density, isothermal nature of the energy storage etc. Solar cooking is one of the solutions to overcome increasing demand of fossil fuels in country like India. However it suffers from problems like low solar intensity, fluctuations during cloudy environment, limited availability (only during few hours of the day), and fluctuations with time. Use of latent heat storage system in solar cooking, can overcome some of the problems listed above. In this paper, efforts were made to gather the information on previous works on solar cooking system using PCM, use of Phase Change Materials (PCMs) for evening / night cooking and conceptual design of solar cooker using PCM. This review will be important for further research in this field. Heat storage system enables cooking food during cloudy sky or in the evening. Hence, solar cooker with PCM storage will increase the utility and reliability of the solar cookers. As the source temperature raises, the chemical bonds within the PCM breaks which changes phase from solid to liquid. The phase change is a heat-seeking (endothermic) process and therefore, the PCM absorbs heat on melting. Upon storing heat in the storage material, the material begins to melt when the phase change temperature is reached. The temperature then stays constant until the melting process is completed. The solar energy stored during day time can be used directly for cooking or can be stored in PCM and used during night/evening time.

Abstract:

Increased energy demand has forced societies to rely on traditional fuel sources with negative health andenvironmental impacts. In most developing countries, solar energy is available for long hours and in ranges thatif exploited can reduce dependence on biomass and fossil fuels. However, despite its potential, uptake of solarcooking devices is low due to intermittent radiation, technological challenges, lack of awareness and slowercooking rates compared to other energy sources. There are four traditional types of solar cookers, box, panel,parabolic and tube. The latest technology is the PV conversion to electricity. Since the advent of solar cooking,numerous experiments, designs and improvements of solar cookers have been successfully developed. Researchhas focused on improving solar cooker performance such as; improved design, sun tracking mechanisms, solarthermal storage or “hybrid” designs that remove limitation of nighttime cooking or periods of poor irradiance.These improvements have increased the efficiency, reduce the cost of the solar cookers, and addressedsociocultural challenges such as sheltered cooking, visual appearance, and the ability to cook traditionalrecipes. However, more needs to be done to increase ease of adoption, the capacity of energy storage andflexibility. The cost of domestic workloads and environmental degradation should also be a factor in energypolicy formulation.
