The invention provides a portable
solar power generation device and a control method. The portable
solar power generation device comprises a control module, a mechanical module and an
energy storage module. The control module comprises an
arduino UNO control board, a
motor control board and four photosensitive sensors. The mechanical module comprises a housing, five motors, two rotating brackets,and
solar cell panels. The
energy storage module is a movable
energy storage device, and is equipped with a
USB circuit output port. When in operation, light rays irradiate on the two pairs of photosensitive sensors inclinedly, illumination intensities received by the photosensitive sensors are different, thus potential differences are generated, and the different potential differences are corresponded to
azimuth and heights of the sun. When the potential differences are higher than a value, the
motor control board controls the motor to rotate, so that the
solar cell panels are perpendicular to the light rays. The portable
solar power generation device has the advantages of high efficiency, small size, automatic
stain cleaning, high intelligence, safe and reliable operation and the like, can be applied to household and industrial power generation, emergency power generation, outdoor travel power generation and the like, and has broad market prospect.
