摘要： The present disclosure provides a thermomechanical actuator and a cleaning system implementing the thermomechanical actuator. The thermomechanical actuator includes a solar heat collector (SHC) housing shape memory alloy springs connected between a piston movably disposed therein and one end of the SHC. A cable extending from the piston through an opposite end of the SHC is connected to a bias load that develops returning force on the springs. In presence of solar radiation, the springs contract and cause linear movement of the piston in a direction of contraction and, in absence of the solar radiation, the springs expand and cause linear movement of the piston in direction of expansion. Useful power and work is extracted in form of the cleaning system from such linear movement of the piston.
