摘要： A foldable parabolic solar collector includes a first panel having a semi-parabolic reflective inner surface, a central tube to which the first panel is fixed, and a second panel having a semi-parabolic reflective inner surface. The second panel is pivotably mounted to the central tube with the reflective inner surface of the second panel facing the reflective inner surface of the first panel. A receiver tube carries a heat transfer fluid. A tracking motor rotates the central tube. A torque sensor lies in between the tracking motor and the central tube and is configured to measure torque between the tracking motor and the central tube. A servomotor pivots the second panel about the central tube between an open position and a closed position when it is determined by a controller that the torque between the tracking motor and the central tube exceeds a predetermined torque threshold.
