Document Type and Number:
WIPO Patent Application WO/2020/217947
Kind Code:
A1
Abstract:
A solar-tracking solar power generation system that comprises an array that receives sunlight and generates power, a support mechanism that supports the array via a drive unit that drives the array around two axes, and a control unit that controls the drive unit so as to make the array track the sun and to make the array perform a retraction operation when retraction is required because of wind. The control unit has a selection function that selects whether to use wind speed or wind load as an indicator to determine whether the retraction operation is necessary and a retraction determination function that uses the selected indicator to determine whether the retraction operation is necessary.
