A solar-tracking system uses a combination of active and passive movement to protect solar panels from wind while maximizing energy production. The system rotates the panels around a vertical axis using a drive mechanism controlled by a computing unit. The panels are mounted on horizontal hinges that allow them to tilt upward automatically when exposed to strong wind. The computing unit uses motor current, cable tension, or torque sensor data to estimate panel orientation and wind conditions, without needing separate wind sensors or angle sensors. The system also adjusts panel orientation to improve power output based on real-time electrical measurements. This approach provides reliable wind protection and efficient solar tracking with minimal hardware.

A tracking system is provided for solar panels, which are controlled by a pre-programmed microcontroller that sends movement control to a stepper motor. The motor has a shaft that transmits the movement to another concentric panel shaft, which is attached to a first solar panel. Its tracking function begins at 6:00 AM at an angle of 90° with respect to the horizontal, and changes 15° every hour. By noon, the panel is parallel to the horizontal, and by 6:00 PM it has traveled 180° from its starting point. This same rotational movement is used by an autonomous cleaning system consisting of a pair of guide profiles located on the sides of the panels. These guide profiles support screws with spherical heads, which have tangential contact between the screw head and the profile. This contact allows the system to clean the panels as they move to follow the sun.The cleaning system moves due to gravity, performing a transverse movement which is transferred by means of cleaning shafts attached to cylindrical head screws. These shafts, in turn, support soft bristle brushes that clean the panels, removing dust and dirt collected on them. To transmit the tracking movement to all the solar panels, a gear is installed on the motor shaft of the first panel. This gear transmits the movement to a second panel via a toothed belt. The movement and position of the first panel is replicated in a second panel configured in the same way as the first, and so on for all the panels that need to be installed. Finally, the seasonal orientation movement is achieved by means of a manual movement plate that is adjusted depending on the season; this adjustment is only made once a month.

A stop (220) formed by a third fold (222) at the second end prevents over-insertion. The differing widths (WL< W2) and heights (HL< H2 = H3) facilitate easy insertion and reliable retention, improving assembly speed and mechanical stability of solar-module coupling.
