Solar Energy Substrate Aerodynamic Flaps

Methods and systems for solar energy capture. One of the systems includes a solar energy substrate mounted on a support member and one or more flap assemblies coupled to the solar energy substrate. The solar energy substrate is configured to receive solar rays from the Sun and is further configured to move in at least one direction such that an orientation of the solar energy substrate can be adjusted in accordance with a direction of the solar rays. The support member is configured to support the solar energy substrate. The one or more flap assemblies each include a flap and an actuator that is configured to move the flap relative to the solar energy substrate. Movement of the flap is controllable to counter a wind-induced moment acting on the solar energy substrate.
