1. A photovoltaic component control device, comprising at least one bypass module, a driving circuit, a power supply module, and a controller, wherein
the at least one bypass module is configured to connect in parallel to at least one photovoltaic component,
the power supply module is configured to connect to the at least one photovoltaic component and the at least one bypass module,
the at least one bypass module is configured to bypass the at least one photovoltaic component under control of the controller,
the driving circuit is configured to drive the at least one bypass module to operate under the control of the controller,
the power module is configured to obtain energy from the at least one photovoltaic component and output the energy to the controller and the driving circuit in a case that the at least one photovoltaic component operates normally and the at least one photovoltaic component is bypassed, and
the controller is configured to control an ON state of the at least one bypass module to control whether the at least one photovoltaic component is in a bypass mode, and
wherein the power supply module comprises a buck circuit configured to, in a case that the at least one photovoltaic component operates normally, convert a voltage output by the at least one photovoltaic component to a second operating voltage.
