Title: Performance Optimization and Verification of a New Type of Solar Panel for Microsatellites
Authors: Teng, L, etc.
Abstract: In this paper, a new method of replacing the conventional honeycomb aluminum panel with 3D metal printing on the microsatellite is presented. The multiobjective optimization method is used to optimize the temperature difference, compression strength, shear strength, and weight of the new type of solar panel structure. The relationships between the structural parameters and optimization targets are established, and the influence of five factors on thermal and structural properties is analyzed. Finally, a group of better structural parameters of the panel is obtained. The relative deviations between simulation analysis and model are 27.45%, 6.12%, 1.365%, and 3.27%, respectively. The optimization results show that the regression model can be used to predict thermal and structural properties of the panel, and the establishment of the model is effective. The analysis results show that the performances can be improved by 91.62%, 46.94%, 17.91%, and 10.28%, respectively. The optimized results are used for 3D metal printing, and the new type of solar panel is obtained. It is proved that the method can effectively improve the thermal and structural properties of the panel and can effectively shorten the development and manufacture cycle of the panel and also reduce the cost. It has high engineering application value.2019-02-27T00:00:00ZAdvanced Nanomaterials and Nanotechnologies for Solar Energy

Abstract: As the world faces serious energy challenges, the development and implementation of renewable energy technologies become increasingly important. Solar energy resource dwarfs all other renewable and fossil-based energy resources combined. This special issue addresses the role of the development of solar energy. The themes include a photocatalytic process, a photoelectrochemical process, a photosynthesis process, solar cell technologies (photovoltaics (PV)), and solar PV/thermal systems, which resulted in a collection of twelve outstanding articles submitted by investigators representing eleven countries across Asia, Europe, and North America.2019-01-01T00:00:00ZModeling and Analysis of Photo-Voltaic Solar Panel under Constant Electric Load

Title: Modeling and Analysis of Photo-Voltaic Solar Panel under Constant Electric Load
Authors: Salilih, Elias M.; Birhane, Yilma T.
Abstract: This paper presents modelling electrical performance of a typical PV panel/module (which is Kyocera 200GT) for constant electric loads (which are 2Ω, 4Ω, 6Ω, and 8Ω) under weather condition of a tropical region. The specific case of the city Jigjiga (9.35°N,42.8°E), located in the Eastern region of Ethiopia is considered. Electrical characteristics of the PV module are determined on the basis of detailed numerical algorithm, which was designed based on tested numerical technique from reviewed articles. The overall evaluation of the hourly variation in the electrical performance of the PV module is done by means of graphical technique, which determines the operating point of the PV module on voltage vs. current plane for each load, and the performance of the PV panel is compared for each load. The 4Ω electric load resulted in highest daily energy output of the PV panel on a daily basis for 11 days of the month of January (out of 12 considered days), but in the last day it resulted in a poorer performance with respect to the other two electrical loads (i.e., 6Ω and 8Ω electric loads).2019-08-01T00:00:00Z
