“…Cooking with solar box cookers has been the most investigated, and well-documented solar cooking method [12,13,14,15]. Solar box cooking experiments have been carried out at intermediate to high temperatures using different test loads and fluids to improve their thermal performance [16,17,18,19,20,21].…”

Biomass and fossil fuels are mostly used in rural areas of developing countries for cooking. These energy resources have negative impacts on the environment and human health mainly due to deforestation and greenhouse gas emissions. A cleaner and environmentally-friendly form of cooking is solar cooking using the sun's energy. Parabolic solar cookers perform better than other solar cookers such as box solar cookers since higher temperatures are achieved in a shorter duration. These higher temperatures allow most types of cooking processes such as; boiling, frying, roasting, and baking to be possible. The major problem with most conventional solar cookers is that cooking is not possible during off-sunshine periods. Integrating solar cookers with thermal energy storage (TES) makes cooking during off-sunshine periods possible. This paper presents a comprehensive review of parabolic solar cookers with TES which is a sustainable cooking solution for developing countries. Previous work on both parabolic trough and parabolic dish solar cookers with TES is presented. Solar cookers with storage are classified according to the two main types of TES technologies which are; sensible heat thermal energy storage (SHTES) and latent heat thermal energy storage (LHTES). The main conclusions of the review are that; parabolic dish solar cookers with TES are more common than parabolic trough cookers, more studies have been done using latent heat storage as compared to sensible heat storage, limited modelling work has been presented, most of the parabolic cookers used aluminum sheets as the reflecting material, large scale experimental studies are limited and fewer studies tackled the techno-economic and socio-economic aspects. The review also highlights research gaps on parabolic solar cookers with TES in terms of the modelling, combined TES (sensible and latent heat), different reflector materials, large-scale experimental setups, and techno-economic and socio-economic analyses. Other important aspects to consider for parabolic solar cookers with TES include; the choice of sensible or latent heat storage materials, environmental impact, types of food to be cooked, and social acceptance.

Amid numerous sources of energy, solar energy possesses calibre to combat energy requisite for various sectors. A lot of significant research work has been carried out on solar energy to maximize its applications and efficiency of available designs. Among many applications, cooking is the one of the dominant application of solar energy. Other than basic design of box type solar cooker, solar collectors are employed in solar cooking system for the feasibility of more effective cooking. This manuscript inhibits various cooking system based on solar collectors like FPC(flat plate collector),ETC (evacuated tube collector),PDC(parabolic dish collector), PTC(parabolic trough collector), fresnel lens based collector and scheffler reflector type collector. Solar collectors based cooker designs render compatibility of cooking regarding cooking load, cost, cooking type, ease of operation and cooking time

“…In applications, and particularly in PV energy cookers, [9][10][11][12] these techniques pose the problems of convergence towards the point of maximum power PPM, 1 of non-optimal operation of converters, of supply of thermal resistances by suitable electrical powers and therefore very low thermal and overall efficiency. In the literature, we find, practically, the absence of reliable results on the feasibility of these new generation cookers with PV energy.…”

In this paper we propose the control of a parallel multi-stage photovoltaic (PV) system using a reliable and precise Maximum Power Point Tracking (MPPT) control strategy. This technique is based on the acquisition of the electrical output quantities (voltage, current, and power), common to DC/DC converters, and the control of the power switches, in alternation. In the case of two stages, during the time t i , converter 1 is regulated in real time by the MPPT control, and the second converter keeps the previous MPPT optimization parameters (t i À 1 ). During the following time t i + 1 , converter 1 retains the previous MPPT optimization parameters (t i ) and converter 2 is regulated in real time by the MPPT controller. The proposed technique is experimented on a photovoltaic system that feeds a solar cooker. This system is formed by a thermal resistance, two types of PV panels (200 and 230 W) and two DC/DC converters. Compared to the classical technique (instantaneous control), the results obtained show a significant performance and improvements: Convergence speed towards the maximum power point PPM of 48%, variations the electrical quantities gaps (current, voltage, power) at the input and output of the DC/DC converters by a factor of 2.46, electrical energy production of 4%, plate heating temperature of 27.3%, and an efficiency of 5%. The temperatures of the thermal resistances are validated by the thermal models established during this work. The improvements in DC/DC converter performance and solar cooker heating temperature are attributed, on the one hand, to the nature of the proposed MPPT control, which reduces the dispersion of electrical quantities at the input and output of the DC/DC converters, and, on the other hand, to the rapid heating of the solar cooker by the electrical energy produced by the photovoltaic panels.
