A protection system protects against incident wind in a photovoltaic installation and a method protects a photovoltaic installation against damage caused by incident wind. The protection system for protecting a photovoltaic installation includes a plurality of parallel and spaced apart rows of solar trackers having a central shaft attached to supports by means of couplings and supporting photovoltaic panel; and at least one actuator device kinetically connected to the central shaft for modifying its angular position. At least one row comprises a deflecting barrier below the photovoltaic panels and between the supports, covering between 40% and 65% of the distance (D) existing between the central shaft and the ground, defining a passage (P) between the deflecting barrier and the central shaft for redirecting the incident wind.

The invention is directed to a construction tube which has a circular cross section, wherein the circular cross section including two circular stretches and two flat stretches diametrically opposite from each other which define two parallel planes interrupting the circular stretches. It enables the advantages of construction tubes with a circular cross section and the advantages of tubes with a polygonal cross section to be combined. The construction tube can be joined to a connectable element, which is preferably selected from another construction tube and an output shaft of a reducer of a solar tracker, in particular, using inner parts and/or clamps. The construction tube of the invention has a special application in solar collection systems, making up a torsion shaft of a solar tracker.

A solar tracker system includes a torque tube, a solar panel assembly attached to the torque tube, a housing defining a chamber and a fluid passageway extending from the chamber, and an active lock connected to a seal configured to prevent a flow path of fluid while in a sealed state and allow the flow path of fluid in an unsealed state. The system further includes a controller in communication with the torque tube and the active lock. The controller is programmed to receive a command to place the solar panel assembly in a stowed position, instruct the torque tube to rotate the panel assembly to a stowed angle corresponding to the stowed position, monitor a current angle of the panel assembly, compare the current angle to the stowed angle, and instruct the seal to transition to the sealed state when the current angle is equal to the stowed angle.
