Abstract
Described herein are improved solar tracker systems having variable profiles and related operating methods thereof. Solar-tracking PV systems with variable twisted or aerodynamic profiles offer several advantages including improved wind stability, improved shading characteristics and/or capability to correct system component misalignment. In an embodiment, motor drives (and locking devices if present) of a PV system can be driven against each other to cause a desirable twisted or aerodynamic profile of a torque tube and associated PV modules mounted on the torque tube. The desired twisted or aerodynamic profiles can range from a substantially flat horizontal plate to a twisted helix-like profile and combinations thereof so as to establish improved wind and/or shading characteristics. Advantages can also include a reduction in structural materials, increased structural strength, increased solar energy yield or a combination thereof.
