SOLAR PANEL ORIENTATION DEVICE Russian patent published in 2024 - IPC H02S20/30 

FIELD: autonomous power supply systems.

SUBSTANCE: invention relates to automatic control systems that orient solar panels, and can be used in the design of autonomous power supply systems to increase the electricity production of solar panels by optimally orienting them without the use of light sensors. The solar panel orientation device contains a movable frame on which solar panels are installed, equipped with a frame rotation system in the form of a vertical shaft and a horizontal shaft installed between the frame and the vertical shaft, driven by electromechanical drives, as well as an automatic control system containing a control unit with sensors voltage and current connected to the output of the solar panel to find the generated power and determine the position with the maximum generated power, and a power module to control the electromechanical drives. Brushless electric motors with worm gearboxes are used to drive two shafts. The position of the solar panels is determined subject to an initial calibration using end position sensors by counting the number of discrete steps of movement of the solar panels without their reverse movement. After the initial calibration, the control unit is configured to measure and store the power generated by the solar panels using current and voltage sensors, alternately transmit commands to the shaft drives to move one step, measure the power generated by the solar panels and make a decision on further movement independently for each shaft. If the power has increased, the control unit transmits a command to the shaft drive to move one more step; if the power has decreased or remained unchanged, the frame stops, with the subsequent movement starting one step after a period of time different for the two shafts.

EFFECT: reducing energy costs when rotating solar panels to the optimal position and increasing the autonomy of the device due to increased reliability.
