Abstract: The photovoltaic industry has developed rapidly, but the research on the basic selection of the photovoltaic brackets is relatively small. The assessment index system is not perfect. This article summarizes the main factors that affecting the foundation of photovoltaic stents, establishing comprehensive aspects of the basic assessment index system to help decision making during the basic selection process of the bracket. The use of hierarchical analysis to quantify the indicator system, to analysis the impact of each evaluation indicator on the basic selection of the bracket are evaluated. The results of this study show that, at the primary level of assessment, “basic stability”, “cost”, and “constructability” hold the most significance. When the decision making regarding the selection of the bracket foundation, these three aspects should be given the utmost considerations. Among them, the “stability of the load”, the “stability of conventional loads”, “construction technology cost” and the “construction period quality” carry the greatest weight, making them the most influential factors in the bracket foundation selection. The results fulfill the research gap in the field of basic selection of photovoltaic brackets, provide useful tools and methods for related fields, and are expected to improve the basic quality and economic benefits of photovoltaic power station projects.
