Abstract

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.

Description

technical field [0001] The invention relates to a portable solar power generating device, in particular to a foldable automatic tracking solar power generating device. Background technique [0002] At present, many solar power generation devices are fixed. This type of solar cell module cannot change with the height and direction of the sun. Most of the time of the day, the light is irradiated on the module obliquely, so the power generation efficiency is low. Can make full use of solar energy resources. [0003] In recent years, with the continuous progress and development of human life, all kinds of handheld electronic products consume more and more power. It is very difficult to charge electronic products when they are outdoors for a long time, so a mobile power supply is needed. The solar mobile power supply uses solar energy to generate electricity, does not need mains electricity, and is environmentally friendly and safe. However, in order to obtain greater power, so...
