A photovoltaic concentrator system, a tracking error detection method, a tracking deviation correcting method, a control device, a tracking deviation detection program, and a tracking deviation correcting program

摘要

A concentrator photovoltaic system comprises: a concentrator photovoltaic panel; a drive device for allowing the concentrator photovoltaic panel to perform the operation of tracking the sun; and a control device for detecting a variation pattern repeatedly occurring in the aging variation of the power generated in the concentrator photovoltaic panel, comparing the detected variation pattern with a form specific for an azimuth error and a form specific for an elevation error, thereby detecting the presence or absence of a tracking error.
