Abstract: Disclosed herein is a technique of configuring flexible photovoltaic tracker systems with high damping and low angle stow positions. Under dynamic environmental loads implementing a high amount of damping (e.g., greater than 25% of critical damping, greater than 50% of critical damping) or a very high amount of damping (e.g., 100% or greater of critical damping, infinite damping) enables the flexible tracker system to prevent problematic aeroelastic behaviors while positioned in a low stow angle. The disclosed technique is further applied to a prototyping process during wind tunnel testing.

Abstract: Systems, methods, and computer-readable storage media for dynamically adjusting nodes in a mesh network embedded in objects. The nodes, which are individually capable of sensing and/or transmitting data, are paired together such that when one node is active, the other node is collecting energy via solar, wind, or other energy collecting means. When a node reaches a certain energy level, the nodes can switch status, such that the passive node becomes active and vice versa. Exemplary objects in which the systems can be embedded include benches, receptacles, and light fixtures.
