A satellite solar power supply module system comprises a solar battery pack, the solar battery pack comprises a plurality of solar battery units, bypass safety parts are arranged in the solar battery units, and when the bypass safety parts are connected, solar battery pieces connected with the bypass safety parts in parallel are discharged out of power supply lines of the solar battery units, the output end of each solar cell unit is provided with an MPPT unit, and the output power of the solar cell unit is maintained at the maximum output power point by using an MPPT algorithm. An actuating mechanism is arranged, and is configured to be capable of maintaining at least one solar cell unit in a fully-shielded, semi-shielded or non-shielded state so as to obtain different maximum output power points under the control of an MPPT algorithm, and the change of the maximum power points and the change sequence from non-shielded to fully-shielded are in a non-linear relation.
