Plant for producing solar energy including a support structure formed from support poles aligned fixed to the ground, a movement system for receiving devices of solar energy positioned on poles arranged in a row, adapted for allowing the movement of the devices about a first axis and a second axis substantially perpendicular to one another, a rotating main tube about the first axis, to which a plurality of secondary tubes is connected, associated with said main tube, the secondary tubes having the receiver devices fixed to them and a movement mechanism for the primary tubes, and a sustaining and movement support arranged on each pole of said row, which has a housing that receives the main tube of the movement system and that allows the rotation thereof about the axis.

A dual drive shaft solar tracker system comprises a photovoltaic (PV) structure, which includes at least one solar panel, a support structure and first and second drive shafts. The first and second drive shafts comprise first and second belt mechanisms wherein movement of the PV structure occurs by wrapping belts of the first belt mechanism onto the first drive shaft and by wrapping belts of the second belt mechanism onto the second drive shaft so as to provide a non-linear wrapping rate to accommodate the non-linearity of the belt wrapping onto the first and second drive shafts. A linkage, which ties two rows that are unbalanced in opposite directions, cancels out the imbalance as long as both rows have identical components. This allows trackers to use PV modules of any size and weight and the perfect balance is unaffected.

A solar panel assembly where a solar panel(s) is mounted on a support pole that is pivotally attached to a footing. By adjusting the angle of the support pole relative to ground, the orientation of the solar panel can be changed in full-axis directions. A plurality of the solar panel assemblies can be arranged into an array of rows and columns. Each row includes a row support cable that is connected to each one of the solar panel assemblies in the row to simultaneously adjust an angle of each of the solar panels in the row. In addition, each column includes a column support cable that is connected to each one of the solar panel assemblies in the column which may be used to simultaneously adjust an angle of each of the solar panels in the column.

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.

Solar trackers that may be advantageously employed on sloped and/or variable terrain to rotate solar panels to track motion of the sun across the sky include bearing assemblies and other mechanical features configured to address mechanical challenges posed by the sloped and/or variable terrain that might otherwise prevent or complicate use of solar trackers on such terrain.
