The PV array support structure pivotally raises its PV array into its operating elevation and positional range with a system of motorized pivot arms operationally positioned between its array columns and the members of the support frame. Once in place, these PV arrays may be horizontally moved by tilting or angling the array columns within a specified operating range (by computer positioning known as dynamic shifting). At the same time, the PV panels may all be optimally tilted for sun sharing and sun shading for both the generation of electricity and to increase the agricultural efficiency of the underlying land. ## Claims ### Claim 1 A dynamically shifting photovoltaic panel array apparatus, comprising: at least one planar platform horizontally translatable between an East and West direction; an array of tiltable photovoltaic panels mounted onto a top of said platform; at least four foundation piers; at least four vertical tiltable array columns having a lower end and an upper end, each said lower end pivotally mounted to one of said at least four foundation piers by a lower pivot assembly, and each said upper end pivotally mounted to said platform by an upper pivot assembly; at least two extendible linear actuators, each having a first end and a second end, each said first end directly connected to said platform and each said second end directly connected to one of said tiltable array columns, and wherein each of said at least two extendible linear actuators is disposed at an acute angle between said platform and one of said at least four tiltable array columns that exceeds zero degrees, so as to enable the horizontal translation of said array of tiltable photovoltaic panels. ### Claim 2 (depends on 1) The dynamically shifting photovoltaic panel array apparatus of claim 1, further comprising: at least one torque tube onto which at least some of said array of photovoltaic panels are mounted; at least one drive motor rotatably connected to said torque tube for the tilting of said at least some of said array of photovoltaic panels. ### Claim 3 (depends on 1) The dynamically shifting photovoltaic panel array apparatus of claim 1, wherein said extendible linear actuators are selected from the group consisting of electric screw jacks, hydraulic jacks or pneumatic jacks with angle limiting stop mechanisms thereon to keep said platform within a preset limit of horizontal travel. ### Claim 4 (depends on 2) The dynamically shifting photovoltaic panel array apparatus of claim 2, wherein said extendible linear actuators are selected from the group consisting of electric screw jacks, hydraulic jacks or pneumatic jacks with angle limiting stop mechanisms thereon to keep said platform within preset limits of horizontal travel. ### Claim 5 (depends on 1) The dynamically shifting photovoltaic panel array apparatus of claim 1, wherein each of said upper pivot assemblies is made of a first coupling half affixed to a distal end of a respective one of said array columns and pivotally connected with a pivot axle to a second coupling half affixed to said platform, and wherein each of said lower pivot assemblies is made of a first coupling half affixed to a proximal end of a respective one of said array columns and pivotally connected with a pivot axle to a second coupling half affixed to a respective one of said foundation piers. ### Claim 6 (depends on 5) The dynamically shifting photovoltaic panel array apparatus of claim 5 wherein each said first coupling half is a plate with a first orifice therethrough, and each said second coupling half is a base plate with a pair of parallel plates with a pair of aligned second orifices therethrough extending normally therefrom, wherein said pair of parallel plates are spaced apart to receive said plate. ### Claim 7 (depends on 4) The dynamically shifting photovoltaic panel array apparatus of claim 4, further comprising: a data acquisition computer in communication with said at least one drive motor communication with said electric screw jacks or hydraulic jacks or pneumatic jacks; a first drive signal sent from said data acquisition computer to said at lease one drive motor to rotate said torque tube and tilt at least some of said array of photovoltaic panels; and a second drive signal sent from said data acquisition computer to said electric screw jacks or hydraulic jacks or pneumatic jacks to extend or retract said jacks and shift said platform in the East or West direction. ### Claim 8 (depends on 7) The dynamically shifting photovoltaic panel array apparatus of claim 7, wherein said first drive signal and said second drive signal are simultaneous signals. ### Claim 9 (depends on 1) The dynamically shifting photovoltaic panel array apparatus of claim 1, further comprising: a platform East travel limit no less than one half of a photovoltaic panel length; and a platform West travel limit no less than one half of said photovoltaic panel length. ### Claim 10 (depends on 1) The dynamically shifting photovoltaic panel array apparatus of claim 1, further comprising: at least four linear actuator mounts, said mounts pivotally affixed between a proximal end of said at least two linear actuators and two of said at least four array columns, and pivotally affixed between a distal end of said at least two linear actuators and said platform.
