Detrimental Impact

Waste disposal in remote areas is a hurdle due to lack of active dumping space. Besides, improper dumping of waste on empty land can have a detrimental impact on the environment. Incineration of waste using thermal incineration (using a solar concentrator) can be utilized for mobile incineration devices to dispose of hazardous waste effectively with a limited space. The design and mobility of the solar dish for this purpose is one of the most important considerations. The modeling of the solar dish was performed on SOLIDWORKS® with APEX® for optical simulation. The simulation results showed a linear variation of flux coating to enable a more comprehensive cost benefit analysis for the design. The simulation was also used to check whether the required flux at focus (to achieve ignition) was achieved. Further work is required to validate the results.

The solar concentrator is the primary means of solving the contradiction between cost and photoelectric conversion efficiency. The design and fabrication of concentrator are the key techniques to accelerate the application of photovoltaic systems. A novel type of composite concentrator is designed, including two mirrors and one planar lens. The primary mirror focuses the sunlight on the secondary condenser, which is one multi-segmented cone mirror to produce homogenization on the solar cell. The selection strategy of structure parameters is analyzed by the numerical calculation methods. The concentration ratio and homogenization on the receiving surface are also obtained using the optical simulation method. The designed mirrors are fabricated by the ultra-precision turning method, and then assembled according to the location parameters designed. The proposed methods are proved to be satisfied with the solar application efficiently by the experiments.

Solar Concentrators

Fresnel solar concentrator is one of the most common solar concentrators in solar applications. For high Fresnel concentrating PV or PV/T systems, the second optical element (SOE) is the key component for the high optical efficiency at a wider deflection angle, which is important for overcoming unavoidable errors from the tacking system, the Fresnel lens processing and installment technology, and so forth. In this paper, a new hybrid SOE was designed to match the Fresnel solar concentrator with the concentration ratio of 1090x. The ray-tracing technology was employed to indicate the optical properties. The simulation outcome showed that the Fresnel solar concentrator with the new hybrid SOE has a wider deflection angle scope with the high optical efficiency. Furthermore, the flux distribution with different deviation angles was also analyzed. In addition, the experiment of the Fresnel solar concentrator with the hybrid SOE under outdoor condition was carried out. The verifications from the electrical and thermal outputs were all made to analyze the optical efficiency comprehensively. The optical efficiency resulting from the experiment is found to be consistent with that from the simulation.

In the field of energy supply to agro-industrial facilities, there is an increasing interest in the development of structures and engineering systems using renewable energy sources, including solar concentrator thermal and photovoltaic modules that combine photovoltaic modules and solar collectors in one structure. The use of the technology of concentrator heat and photovoltaic modules makes it possible to increase the electrical performance of solar cells by cooling them during operation, and significantly reduces the need for centralized electricity and heat supply to enterprises of the agroindustrial complex. (Research purpose) The research purpose is in numerical modeling of thermal processes occurring in a solar concentrator heat-photovoltaic module. (Materials and methods) Authors used analytical methods for mathematical modeling of a solar concentrator heat and photovoltaic module. Authors implemented a mathematical model of a solar concentrator heat and photovoltaic module in the ANSYS Fluent computer program. The distribution contours of temperature and pressure of the coolant in the module channel were obtained for different values of the coolant flow rate at the inlet. The verification of the developed model of the module on the basis of data obtained in an analytical way has been performed. (Results and discussion) The results of comparing the calculated data with the results of computer modeling show a high convergence of the information obtained with the use of a computer model, the relative error is within acceptable limits. (Conclusions) The developed design of the solar concentrator heat and photovoltaic module provides effective cooling of photovoltaic cells (the temperature of photovoltaic cells is in the operating range) with a module service life of at least twenty-five years. The use of a louvered heliostat in the developed design of a solar concentrator heat and photovoltaic module can double the performance of the concentrator.
