“…Concentrated solar power (CSP) technology is one of the way to generate electricity by producing heat when sunlight focuses on a receiver [6,[12][13]. This technology uses optical component either mirrors or lenses or any reflective type material to concentrate a large area of sunlight into a small beam to heat up the receiver for steam converted to electricity [7][8][9]. There are three common methods to concentrate the sunlight, i.e.…”

“…The modes of these drives are single axis and dual axis including temperature, solar irradiation and installed system area factors. The active drive type tracking system is much adopted drive compared to passive drive with single axis, vertical single axis and azimuth dual axis tracking Modes [6][7][8].

This paper demonstrates the designing parameters of a solar parabolic dish prototype for rustic areas with great solar irradiance rate availability, where have no access of electricity services or low-income people survives to buy a stove (electric or gas). The solar parabolic dish prototype intends a solution against these types of remedies and pursues solar light to work. The parabolic dish has a polished surface, where the solar radiations fall and collected at a single concentrated focal point. At this point the collected form of energy is used to derive different thermal applications like as; cooking & heating with single and dual axis schemes. This paper discusses the important stages of dual axis prototype; implementation, solar location strategy, the analysis in terms of theory, structural design & material. The dual axis prototype is implemented through the help of Arduino chipboard that is easily in maintenance, along with that this prototype is configured with anti-lock H-bridge (L298) module to overcome the control circuit complexity and AVR modules. Two rotational motors of 12V are installed on 4*4ft designed aluminum frame with a dual-axis tracking system. The jerks among trackers are also reduced with this prototype which maintains the experimental declination angle about .To finish, this paper results that parabolic solar dish tracker obtains 3.43% improved power efficiency in comparison of photovoltaic panel tracker.

An alternative way to generate electricity from solar energy is through the use of generators comprising Stirling engines with a parabolic collector. This study describes a parabolic collector with Stirling engine and investigates the design of a linear mobile generator for these systems. Especially for direct drive in free piston mechanisms proposed for these systems, linear generators are important due to their advantages such as compact structure, light weight, high efficiency and high power intensity. Although conventional one‐phase and three‐phase multi slot/pole models are widely available in the literature, three phase is considered for lower PM cost and to reduce the cost of power electronics and 3/2 slot/pole combination is considered for high speed and frequency. In this study, a new 3/2 slot/pole three‐phase tube‐type linear generator was designed and evaluated for performance and manufacturability. Objective functions were defined for power and efficiency increase to reduce generator power ripple, and the results of Mixed‐Integer Sequential Quadratic Programming, Multi‐Objective Genetic Algorithm (MOGA), and Screening methods were compared and examined. Performance of the two‐dimensional and optimized models was evaluated in terms of induced voltage, power density, efficiency, and output power. The best results were found with MOGA compared to other methods. When compared with the initial value, there was a 97.3% increase in power density for a 32.4% increase in moving weight. Moreover, the efficiency of the MOGA model is improved by 16.2% compared with the initial model. Additionally, significant improvements were shown in terms of thrust coefficient, voltage coefficient, power, and no‐load voltage. A prototype of the model was made and a motor‐driven crank mechanism system was used in place of the Stirling engine to undertake practical measurements.

“…Unfortunately, most of the research focuses on each component individually. Indeed, limited studies [12][13][14][15][16][17][18] have addressed the whole system and the interactions between its components. Yaqi et al, [12] developed a general analytical model for the maximum output power and its corresponding thermal efficiency.…”

Design and three-dimensional simulation of a solar Dish-Stirling (SDS) engine is currently performed. The design starts with the GPU-3 Stirling engine, which is originally built to generate power from the fossil fuel exclusively. The design is conducted through three subsequent phases. Firstly, several parabolic dishes with different rim angles and number of facets are investigated to optimally design the dish concentrator. Secondly, different relative positions of the receiver aperture to the dish focal plane are tested to reach the optimal position. The optical simulation of the solar concentration process is carried out using SolTRACE software. Finally, an optimal design for a cavity receiver that involves a new structure of the heater tubes is performed. The simulation of the engine with the designed receiver is implemented using the commercial CFD code ANSYS FLUENT. Having finished the design, a comprehensive energy analysis of the designed SDS engine is carried out. The results show that a nearly uniform temperature distribution of the heater tubes throughout the cycle is achieved. The overall thermal efficiency of the designed SDS engine is about 31.8 % at a DNI of 1000 W/m2.
