A door includes a door panel and an electric lock device including a solar energy module, a biometric verification module, a control module and an electric lock. The solar energy module converts solar energy into an electricity output. The biometric verification module receives a biometric input signal relative to a biometric feature, determines whether the biometric feature conforms with a set of pre-established data, and generates a conforming signal if the determination is affirmative. The control module receives the conforming signal to generate a control signal and an unlocking signal. The electric lock receives the control signal and the unlocking signal. The electric lock operates to unlock the door panel.
