Adaptable orientation optimization for vehicles with solar photovoltaic surfaces

Abstract

Solar power generation panels added on a transportation vehicle have a layout wherein power output of the panels varies according to an azimuth orientation of the vehicle. A controller includes a database of calibration curves relating an expected power output to a respective range of the azimuth orientation according to different solar altitude angles. A self-learning sequence is performed which (a) collects a magnitude of power output while the vehicle traverses the respective range of the azimuth orientation, (b) identifies a current solar altitude angle, and (c) stores a resulting calibration curve. A parking sequence comprises (a) selecting a calibration curve according to solar altitude angle, (b) determining a target vehicle azimuth angle which optimizes a cumulative power output based on the calibration curve and solar azimuth, and (d) initiating a movement of the vehicle to orient it at the target vehicle azimuth angle.
