Title: SOLAR ENERGY HARVESTING SYSTEMS INCLUDING AT LEAST ONE THERMAL-MECHANICAL ACTUATOR FOR SOLAR TRACKING
Abstract:
Embodiments relate to a solar energy harvesting systems that include at least one solar panel configured to adjust an orientation thereof and where the adjustment is obtained solely by thermal-mechanical actuation. In an embodiment, a solar energy harvesting system is disclosed, which includes at least one support structure pivotable about at least one pivot axis, and at least one solar panel supported by the at least one support structure and pivotable about the at least one pivot axis. The system includes at least one thermal-mechanical actuator configured to convert thermal energy to mechanical energy, and at least one actuation link coupling the at least one thermal-mechanical actuator to the at least one solar panel. The link is configured to cause the at least one solar panel to pivot about the pivot axis responsive to the actuator converting the thermal energy to the mechanical energy.
