A Study on Development of Azimuth Angle Tracking Algorithm for Tracking-type Floating Photovoltaic System

Abstract

Since floating facility with mooring system has the overall structure move and rotate by wind or environmental variables, the error in azimuth angle must be compensated using GPS receiver and geo-magnetic sensor. Accordingly, when the existing photovoltaic tracking algorithm is applied to floating photovoltaic system as is, optimal photovoltaic tracking cannot be performed. In this paper, a tracking-type floating photovoltaic model was manufactured to develop an effective azimuth angle algorithm for photovoltaic tracking in floating condition, and the developed algorithm was applied for verification.
