    Abstract: Methods and systems of managing dynamic response to wind in a solar tracker system are provided. The method includes determining a wind speed, comparing the wind speed to a predetermined threshold value to determine if the wind speed equals or exceeds the predetermined threshold, positioning a windward most solar tracker to a predetermined angle based on the comparing, and positioning a leeward most solar tracker to the predetermined angle based on the comparing. The solar trackers are positioned at the predetermined angle at a predetermined interval starting at the windward most solar tracker and the remaining solar trackers remain in a normal operating condition.
