The type of bracket in photovoltaic power generation is closely related to the power generation capacity. In order to fully compare and analyze the technical economy of various types of brackets to guide engineering practice, this paper selects fixed, fixed adjustable, flat uniaxial, oblique uniaxial and biaxial five types of brackets as the research object, taking three typical locations in Xinjiang as examples, using METENONRM solar irradiation data resources and PVSYST simulation software, through the calculation and analysis of technical and economic indicators, it shows that with the increase of latitude, the solar irradiation gain of the tracking bracket increases, and the irradiation gain of the Altay tracking bracket is greater than that of Hami and Kashgar. Among them, the irradiation gain of the biaxial tracking bracket is the most significant. The optimal bracket types of photovoltaic projects in the above three locations are oblique uniaxial, flat uniaxial and oblique uniaxial, which are better than fixed adjustable brackets. In addition, compared with the five types of P-type components, the average additional power generation of N-type components in each region is 2.31 %, 2.34 % and 2.41 %, and the investment income of N-type components is higher than that of P-type components.
