Modular tracker systems that include at least first and second tables or are continuous without the use of tables, a single motor driving the first and second tables, first and second intra-table drive shafts and an inter-table drive shaft. Each table includes a support structure including first and second mounting posts, a frame supported by the support structure, at least one solar panel supported by the frame, and first and second gearboxes being concentrically aligned for each table. The first and second gearboxes are each configured to produce first and second outputs. The first output has a first rotational speed, and the second output has a second rotational speed less than the first rotational speed, and is operatively coupled to the frame. The inter-table drive shaft couples the second gearbox of the first table with the first gearbox of the second table, whereby the first and second tables are rotated synchronously.

A series of photovoltaic panels (PV) arranged on a planar, horizontal support platform so as to form a PV array that is pivotally connected to a PV array support structure that can pivotally raise, angle and support the PV array above agricultural fields at heights that allow the passage of large mechanized farm equipment to pass beneath. 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.

A solar tracker comprises a support frame, a panel assembly comprising one or more solar panels, and an actuator to rotate the panel assembly to track the movement of the sun. The panel assembly comprises a central spine and one or more panel carriers extending transversely over the top of the central spine for supporting solar panels. The panel carriers are secured to the central spine by respective support brackets. The support brackets comprise a top surface, side walls extending downwardly from opposing sides of the top surface, and a slot with a downwardly facing opening extending transversely through the sidewalls. The slot is configured to receive the central spine.

Disclosed is a load-bearing structure for single-axis for tracking photovoltaic panels including: first and second support beams for photovoltaic panels, having a longitudinal axis; crosspieces fixing the photovoltaic panels to the first and second beams; support poles for the first and second beam, secured to the ground and having a hinge allowing rotation of the beams about their axis; a linear actuator with first and second ends, the first being hinged to one of the support poles of the first beam; first and second cranks associated respectively with the first and second beams, and imparting a rotation movement thereto; and a connecting rod between the first and second cranks. The second end of the linear actuator is hinged to the connecting rod, allowing simultaneous and coordinated movement of the first and second cranks and the consequent simultaneous and coordinated rotation of the first and second beam of the structure.

Solar tracking installation includes first movement assembly which functionally engages with the primary axis shaft to cause rotation of the primary axis shaft around the primary axis for moving the plurality of planar modules of solar collector elements in a first rotational direction around the primary axis. The installation further includes a second movement assembly which functionally engages with the secondary movement member to cause tilting of each of the plurality of planar modules of solar collector elements around each respective pivotal mount. In this way the movement of the multitude of solar collection elements is a combination of the rotation of first movement assembly and the tilting motion caused by the second movement assembly.

The present invention relates to a tracking photovoltaic solar system comprising at least a tracker unit maintaining an array of photovoltaic modules (101) aligned to the sun during the course of the day. The tracker unit includes: a support structure (100), said support structure comprising a plurality of elongated elements (105) supporting said array of photovoltaic modules and a torque tube (104) for rigidly supporting said plurality of elongated elements and arranged to rotate along a first rotational axis (106), a pole structure (200) operably connected to said support structure, having an upper part rotationally fixed along said first rotational axis (106) on said support structure, and a lower part rotationally connected along a second rotational axis (204) orthogonal to the first rotational axis on foundations (500), and a steering mechanism (300) mechanically coupling together said first and said second rotational axis for rotating said support structure and said operably connected pole structure around said first and second rotational axis in the same movement.

Tracking systems for adjusting a photovoltaic array are disclosed. In some embodiments, the tracking system includes an actuator that moves one or more links to cause the array to rotate. The tracking system may be disposed below a torque rail of the tracking system. The actuator may be a slew drive that retracts or extends the one or more links to cause the array to rotate.

An integrated wind and solar solution is provided, including a solar energy collection assembly (100) and a vertical axis wind turbine (400), combined to provide an integrated power output. In preferred embodiments, the vertical axis wind turbine is positioned above the solar energy collection assembly. Concentrating solar mirror collectors (116) are used to direct sunlight to a heat engine (250), which converts the collected heat energy into rotary motion. Rotary motion from the heat engine and from the vertical axis wind turbine preferably are on the same rotating axis (600), to facilitate load sharing between these two sources. A dual axis azimuth-altitude solar panel alignment tracking system is used in order to boost the energy conversion capability of the solar energy collectors.

Disclosed embodiments provide apparatuses and techniques for use and construction of a two-axis solar tracking device that closely approximates the efficiency of Vertical Biaxial Trackers but with simplified construction, and thus are cost competitive with uniaxial horizontal tracking systems. The flexible mounting system can accommodate both photovoltaic and solar thermal panels. Disclosed embodiments provide a solar panel stand that provides biaxial tracking for solar energy generation efficiency, with reduced cost and complexity, enabling more off-grid and micro-grid energy generation capabilities.
