The present invention relates to new energy vehicle field, and more particularly to vehicle-mounted tracking solar power generation system without photoelectric sensor. The current vehicle-mounted thin-film solar power generation device has a low power generation, inductive tracking technology has high cost and large volume, so neither of them can meet the electricity demand of new energy vehicles, therefore, at the moment when the photoelectric conversion rate is difficult to effectively improve in the short term, making the vehicle-mounted photovoltaic power generation system not only able to track but also has practicality, has become a technical problem that needs to be solved urgently in the vehicle-mounted solar charging industry, the present invention provides a solar tracking technology that adopts a combination of the orbital device and the platform, does not require real-time tracking and photoelectric sensors, and solves the above-mentioned technical problems well.
