Energy need for cooking in both the rural and urban areas all over the world is increasing every day as a result of an increase in population. The consequence of global warming due to the usage of fuels such as fossil fuel, firewood, and other biomass products for cooking necessitates innovative techniques that will improve the standard of living of people. In this study, the design, fabrication, and thermal evaluation of a solar cooking system integrated with an Arduino-based tracking device and sensible heat storage (SHS) materials was investigated. During the water boiling trials with black oil sensible material (BOSHSM), the obtained maximum temperatures for water, cooking box, and sensible heat storage material at 14:00 h when the solar radiation attained its peak value of 881.2 W/m2 were 64,52, and 54°C, respectively, while at 14:00 h with Black coated granite sensible heat storage material (BCGSHSM) at the solar radiation peak value of 890.4 W/m2, the maximum temperatures for water, cooking box, and sensible heat storage material were 73.5, 76, and 59°C, respectively. The maximum cooking power and thermal efficiency obtained from the water boiling trials were 48.4 and 56.4 W, and 31.6 and 35.8% respectively. Also, the results from the cooking of edibles revealed that the cooking power values ranged between 42.5 and 58.2, while that of efficiency ranged between 34.5 and 40.3% respectively. The maximum solar radiation during the cooking trial period was 986, 975, 956, and 953 W/m2. In general, from the results, the developed solar cooking system is a viable alternative to cooking with traditional/open burning of wood or other biomass products that pose a serious environmental and health-related threat to the people living in developing countries.
Cooking is one of the major domestic activities that require energy for human sustenance. All over the world, energy for cooking is being sourced for using different types of cooking fuels such as fossil fuels, firewood, charcoal, etc. are in use. Due to the increase in the cost of cooking gas, fossil fuel, and also the epileptic nature of power supplies in developing countries, the majority of people in the rural and urban areas still use firewood for cooking (Komolafe and Awogbemi, 2010). Burning of firewood, charcoal, or crop residue, slash and burn agriculture, and deforestation account for 5–20% of all carbon emissions worldwide (Smith et al., 1993). Energy experts all over the world have recently become more conscious of the adverse effects of global warming as a result of the usage of non-environmental and eco-friendly fuels such as fossil fuel, firewood, charcoal, etc. Harnessing the abundant potentials in the freely given renewable energy source (Sun) which is clean, safe, and readily available for cooking has become a burning issue and most attractive alternative. History made it clear that the idea of using solar energy for cooking started in 1,650 as a result of fuel shortages and rationing arising from the second world war (Wentzel and Pouris, 2007). Using solar cooking would not only eliminate or at least reduce the respiratory illness arising from the exposure to smoke but could also be used to defeat another scourge of the developing world, contaminated water (Tucker, 1999). Solar cookers are classified broadly into two categories, the box, and the concentrating type. The box-type permits solar radiation directly through the glass window for cooking while the concentrating type uses parabolic or spherical, linear fresnel reflectors and a central receiver tower with the cooking pot positioned at the focal point where the Sun rays are focussed (Kumaresan et al., 2016; Noman et al., 2019).
Several studies on various configurations of the box and concentrating types of solar cookers have been reported (Kumar et al., 2008; Akoy and Ahmed, 2015; Hafez et al., 2016; Noman et al., 2019). However, in an attempt to increase the performance of solar cooking systems, researchers have suggested the use of thermal storage materials (sensible, latent heat, and thermochemical). Sensible and latent thermal energy storage has become a critical feature of energy management, with prominence in the effective use and reuse of waste heat and solar energy not only in manufacturing and buildings but also for cooking (Goldstein et al., 2006). The use of thermal energy storage is crucial whenever there is a mismatch between the supply and demand for energy. Based on the cost of the three identified types of thermal storage materials, sensible thermal storage materials is cheaper and readily available for people in rural areas and some urban areas of developing countries like Nigeria. Table 1 presents the summary of studies on solar cooker with thermal storage materials (Hussein et al., 2008; Saxena et al., 2013a; Saxena et al., 2013b; Kumaresan et al., 2016; Saxena and Karakilcik, 2017; Yadav et al., 2017; Bhave and Thakare, 2018; Coccia et al., 2018; Saxena and Agarwal, 2018; Keith et al., 2019; Khallaf et al., 2020; Omara et al., 2020; Saxena et al., 2020; Hosseinzadeh et al., 2021; Kanyowa et al., 2021). Some authors have reported integration of tracking device (Sun tracker) (Roth et al., 2005; Regin et al., 2008; Skouri et al., 2016; Herez et al., 2018; Babu et al., 2019). (Roth et al., 2005; Regin et al., 2008; Skouri et al., 2016; Herez et al., 2018; Babu et al., 2019). However, heating of the cooking pot/vessel through the parabolic dish and cooking box at the same time has not been reported.
In this study, therefore, design, fabrication, and thermal evaluation of a solar cooking system integrated with a photovoltaic controlled Arduino-based data logging cum tracking device and sensible heat storage materials (Black coated granite and used engine oil) for both the rural and urban areas are presented.
2 Materials and Methods
2.1 Material Selection
Locally sourced and eco-friendly materials such as aluminum sheet, angle iron, mild steel pipes, plywood, reflective glass, Rockwool, aluminum foil, etc. were selected for the fabrication solar cooking system based on design consideration, preliminary investigation, etc. Also, black coated granite and used black engine oil (black) were used as sensible heat storage materials. Fresh and clean samples of sweet potato and plantain purchased from the neighbouring market were used for the performance evaluation of the cooking system. The measuring instruments and thermophysical properties of SHS are shown in Tables 2–4 respectively.
TABLE 3. Thermo-physical properties of engine oil (Sharma et al., 2009).
TABLE 4. Thermo-physical properties of granite (Bejan and Kraus, 2003).
2.2 Description of the Parabolic Solar Cooker
The experimental set-up of the fabricated solar cooking system is presented schematically and pictorially as shown in Figures 1, 2 respectively. It comprises mainly four components namely: the parabolic solar reflector, cooking box, data acquisition and tracking device and supporting frame.
(a) Parabolic reflector: The reflector was fabricated from an aluminum sheet. It is 110 mm in diameter and 150 mm deep. It was cut and glued to the parabolic reflector’s surface.
(b) Cooking box: The cooking box has an overall dimension of 1,376 × 1203 × 1,203 mm. It has three of its sides made of wood (lagged with Rockwool for insulation) and the other three reflective glass. The three glasses were located at the top, bottom, and one of the sides of the box to allow the Sun rays into the cooking pot. Inside the cooking box, were a cooking pot made of aluminum sheet and a compartment for heat storage material as shown in Figure 3.
(c) Data acquisition and tracking device: The data acquisition and tracking device consists of eight major components namely; micro-controller, Bluetooth module, SD card, real-time clock, temperature sensors (DS18B20), Humidity sensor (DHT22), battery, solar panel, and stepper motor.

2.3 Experimental Procedure
Water boiling and cooking tests were carried out in November 2019 between 8:00 and 17:00 h to evaluate the performance of the tracking device integrated cooking system using black-coated gravel and used engine oil. The experimentation site was Teaching and Research Farm, Landmark University, Omu Aran, Nigeria which is located at latitude 8.8oN, longitude 5.5oE. Prior to the cooking tests, water boiling trials were conducted in order to ascertain the thermal response of the system with SHS materials. Thereafter, two edibles (Rice and plantain) were used for the cooking tests. The time, date, relative humidity and temperature of water in the pot and other locations within the cooking system data were programmed to be collected by the micro-controller (Atmeg) from the real-time clock chip (DS1307) and stores it in the SD card at intervals of 10 min. The stored temperature solar radiation, data were retrieved from the solar cooker via the Bluetooth connection without any physical contact with the SD card or device. Data for solar radiation, relative humidity, wind speed and ambient temperature were also monitored and recorded for comparison with readings from the installed Campbell Scientific Ltd. made metrological station at Landmark University Teaching and Research Farm which is just a few centimetres away from where the solar cooking system was positioned. The solar tracking device tracks the Sun with the help of two light sensors and a stepper motor. The two LDR (Light dependent renters) were used to monitor the light rays at opposite sides of the parabolic dish. The microcontroller was also configured and programmed to monitor the direction of light rays and to move the parabolic collector with the aid of a stepper motor towards the direction of the sensor with higher light rays. However, when the light ray sensors on both sides sense an equal ray of light, the stepper motor adjusts and position the parabolic reflector at the centre. Specification of measuring device is shown in Table 1.
2.4 Theory and Analysis
2.4.1 Parabolic Concentrator
Various components of the solar cooking system were designed using the following parameters (Stine and Diver, 1994; Sup et al., 2015; Hafez et al., 2016; González-Avilés et al., 2018; Babu et al., 2019; Noman et al., 2019; Ahmed et al., 2020).

2.4.3 Thermal Modelling
The available energy is absorbed by the cooking fluid while the unavailable is lost to the surrounding by convection and radiation. The energy balance equations for various components of the cooking system namely; the parabolic reflector, Vessel (cooking pot), vessel fluid, energy storage material, cooking box glass cover and the enclosed air cover were written (Mbodji and Hajji, 2017; Yettou et al., 2019; Khallaf et al., 2020; Bhavani et al., 2021). The following assumptions were made:
a. Thermo-physical properties of air, glass, and reflector/absorber remain constant within the cooker temperature range.
b. Proper thermal contact between cooking pot and reflector/absorber surface of the cooker.
c. Negligible heat transfer by reflection between the sidewalls and cooking pot.
d. Exchange of heat as a result of air within the lid covered pot not considered.

3 Results and Discussion
Figure 3 shows the plot of solar radiation and the temperature of the water, cooking box, sensible heat storage material, and air against time with used engine oil as sensible heat storage material. It is evident from the figure that the temperature of the water and that of other locations within the cooking system were almost the same in the early hour of the experiment and began to vary from 11:00 h. The observed temperature profile follows the same pattern with the solar radiation. Thus, an increase in solar radiation resulted in to increase in temperature. The obtained maximum temperatures for water, cooking box, and sensible heat storage material at 14:00 h when the solar radiation attained its peak value of 881.2 W/m2 were 64,52, and 54°C, respectively. The figure further revealed that at 17:00 h when the lowest solar radiation value of 80 W/m2 was attained, the temperatures of water and the cooking box were 50 and 53°C, respectively. This could be attributed to the incorporation of insulating and heat storage materials into the cooking box.
The variation of relative humidity and the temperature of the water, cooking box, sensible heat storage material, and air against time with used engine oil (black) as heat storage material is shown in Figure 4. It can be seen that the relative humidity decreased with time as the temperatures increased. The relative humidity minimum and maximum values of 57.2 and 88.6% were attained at 15:00 and 17:00 h respectively. When compared with Figure 3, solar radiation and temperatures decreased as the relative humidity increased and vice versa.

Figure 5 depicts the variation of solar radiation and the temperature of the water, cooking box, sensible heat storage material, and air with time. From the graph, it is evident that the temperature profile follows the same pattern with the solar radiation in a similar manner to Figure 3. However, the maximum temperatures for water, cooking box, and sensible heat storage material at 14:00 h when the solar radiation attained its peak value of 890.4 W/m2 were 73.5, 76, and 59°C, respectively. The difference in these temperature values and those reported in Figure 3 could be attributed to the irregular intensity of solar radiation or the thermal conductivity of the sensible heat storage materials used. Similar reports have been presented by (Komolafe and Waheed, 2018).
