Embodiments disclosed herein relate to solar tracking apparatuses, systems that include the same, and methods of operating the same. An example solar tracking apparatus includes a structure attachment portion configured to be attached to a structure (e.g., a moveable or stationary structure) and to remain relatively stationary relative to the structure. The structure attachment portion may include one or more mounts configured to attach the structure attachment portion to the structure. The solar tracking apparatus also includes at least one solar panel portion coupled to the structure attachment portion. The solar panel portion may be configured to move relative to the structure attachment portion and the structure. For example, the solar tracking apparatus may include one or more actuators coupled to solar panel portion configured to move at least a portion of the solar panel portion relative to the structure attachment portion.

The present invention relates to a photovoltaic plant including a plurality of units each having at least one respective photovoltaic panel, a support structure of the plurality of units designed to support the latter at a distance from the ground (GR).

A method allows positioning the tracker at angles that promote the cooling of photovoltaic modules and therefore, decrease their operating temperature, without reducing the total energy produced thus optimizing power production of photovoltaic (PV) electricity by reducing the working temperature of PV modules of a solar tracker. The method also provides an optimization of the electrical output of the system for particular conditions of instantaneous air temperature and wind speed to improve electrical power generation ratios with respect to those known current techniques taking into account incident power in the PV plane, or in some cases the output power without considering the action of changes in wind speed or air temperature.
