The invention discloses an elevator power supply source, comprising a commercial power input terminal and a second power source input terminal. The invention is characterized in that the second power source comprises a solar photovoltaic cell and an electrical energy recovery module, solar energy is converted to electric energy by the solar photovoltaic cell, the electric energy generated under generating mode of the elevator is received by the electrical energy recovery module, the solar photovoltaic cell and the electrical energy recovery module are connected with the input terminal of a voltage preference module, the output terminal of the voltage preference module is connected with a storage battery, and the storage battery provides a second power supply voltage for elevator operationby an inverter. The invention has the advantages that electric energy changed by utilizing solar energy and electric energy generated under generating mode of the elevator are input into the storage battery by virtue of the electric energy recovery module, the storage battery is used as the second power source of the elevator by virtue of the inverter, can partially substitutes commercial power tooperate, and can drive the elevator to operate normally when commercial power is interrupted or the power is cut off, thus improving using convenience of the elevator.
