Air conditioning system and method of using solar cell

The present invention introduces an air conditioning system using a solar cell (10), which uses the electricity effectively by heating the heat devices (51,52,53) for designated time and a method for driving the system. The air conditioning system includes a solar cell generating electricity from solar light, a power distribution control part (20) controlling operating voltage of the electricity of the solar cell (10) and distributing to a battery (60) or to the heating element, a control terminal (40) generating a user command signal and an interface part (30) controlling the power distribution control part in response to a command signal from the control terminal.
