ARTICULATING SOLAR TRACKER SUPPORT

Resumen de: WO2025030106A1

This disclosure describes an articulated support for a solar array that enables installation of the array upon uneven terrain while still enabling solar tracking using a rotating shaft. By using articulating supports as discussed herein, a single motor or actuator can rotate a tracking shaft, and thereby rotate each panel attached to the shaft, even when the solar array does not form a straight line. For example, if support piles for the array initially start on flat terrain, then climb an incline, a single rotating shaft would need to "bend" in order to follow the curvature of the terrain, yet still be able to transmit torque. Because of the forces generated by such a "bend" when using conventional supports in an uneven environment, the torque required to rotate a single shaft will be higher than that required to rotate a series of shafts using the articulated supports discussed herein.
