What Is The Higher Power Generation Of The Oblique Uniaxial Subarray And The Fixed Subarray?
May 11, 2018

As we all know, in the photovoltaic power generation system, the mounting method of the bracket is different, and the power generation amount is also different. Then, which photovoltaic system with oblique single-axis tracking and the photovoltaic system with a fixed-inclination type yield higher power?


The fundamental reason is: Compared with the horizontal installation method, the surface of the fixed-tilt sub-array component sacrifices part of the solar radiation energy in the summer, and increases the solar radiation energy in the winter, so that the solar radiation energy received by the component surface throughout the year is relatively balanced. The oblique uniaxial sub-array component surface can significantly increase the solar radiation energy in each month, so the oblique uniaxial subarray has the largest proportion of power generation increase in the summer than the fixed subarray and the minimum increase in the amount of power generation in the winter.


Therefore, in the construction of photovoltaic power plants, on the one hand to consider the station radiation resources (radiation, direct ratio, etc.), on the other hand to consider the construction cost of inclined single shaft and fixed two installation methods, staffing and post- Operation and maintenance costs, and ultimately a reasonable choice of system installation.
