The invention relates to the field of vehicle-mounted solar charging, in particular to a vehicle-mounted solar charging method and related equipment. The method comprises the following steps: determining whether the generated power of a photovoltaic panel meets a charging starting condition or not; if the charging starting condition is met, a pre-stage transformation circuit is controlled to modulate a power supply output by the photovoltaic panel into a low-voltage power supply based on a maximum power tracking algorithm; when the generated power of the photovoltaic panel is greater than a first threshold value but less than a second threshold value, controlling a post-stage transformation circuit to boost the low-voltage power supply and then charging a power battery in a pulse charging mode; and when the generated power of the photovoltaic panel is greater than or equal to the second threshold value, controlling a post-stage transformation circuit to boost the low-voltage power supply to the required voltage of the power battery in a voltage following charging mode, and then charging the power battery. Maximum power tracking and voltage following charging are respectively realized through two stages of voltage transformation circuits, so that the utilization rate of solar energy is improved.
