Abstract

Solar tracker systems include a torque tube, a column supporting the torque tube, a solar panel connected to the torque tube, and a damper assembly. The damper assembly includes a first end pivotably connected to the torque tube and a second end pivotably connected to the column. The damper assembly further includes an outer shell, a piston within and moveable relative to the outer shell, a first chamber wall and a second chamber wall within the outer shell at least partially defining a chamber, and a valve within the chamber. The valve includes a first axial end defining a slot and is biased to a first position within the chamber in which the first axial end is spaced from the first chamber wall. The valve is moveable within the chamber from the first position to a second position to passively change a flow resistance of the damper assembly.
