Multi-pivot joint support structures for solar trackers

A solar tracker support structure comprising:

• a first leg, the first leg comprising a first leg proximal end portion and a first leg distal end portion;
• a second leg, the second leg comprising a second leg proximal end portion and a second leg distal end portion;
• a bridge extending between the first leg proximal end portion and the second leg proximal end portion;
• a first pair of pivot joints comprising a first pair first pivot joint at the first leg and a first pair second pivot joint at the second leg, the first pair of pivot joints configured to move the solar tracker support structure about a first axis;
• and
• a second pair of pivot joints comprising a second pair first pivot joint at the first leg and a second pair second pivot joint at the second leg, the second pair first pivot joint spaced apart from the first pair first pivot joint along the first leg, the second pair second pivot joint spaced apart from the first pair second pivot joint along the second leg, the second pair of pivot joints configured to move the solar tracker support structure about a second axis,
• wherein the second pair of pivot joints are configured to impart yaw at the solar tracker support structure to cause the solar tracker support structure to twist about the second axis.
