PURPOSE: A solar power controller is provided to improve work efficiency by automatically switching solar power to utility power. CONSTITUTION: A power input unit(10) receives power through a sunlight collector or an external power supply unit. A controller(20) is comprised of a microprocessor, a timer, a watt-hour meter, and a driving memory. A switching unit(30) selectively connects the progressing path of power inputted through the sunlight collector or external power supply unit. A relay(40) selectively outputs DC power or AC power. An inverter(50) converts DC power outputted from the relay to AC power. A sensor is comprised of an impact sensor and a current sensor.
