<p>PURPOSE: A light emitting diode (LED) address display panel using a solar cell module is provided to enable an address to be easily distinguished at night. CONSTITUTION: An LED address display panel comprises a controller (100), a solar cell module (120), a brightness sensor (140), a timer (160), and an LED display unit (190). The solar cell module collects solar thermal energy to generate electricity. A battery stores the electricity generated by the solar cell module. The LED display unit displays an address by driving a light emitting diode using the electricity charged in the battery. The brightness sensor senses a brightness value. The timer measures a current time. When the time measured by the timer is a night time, the controller controls the electricity stored in the battery to be supplied to the light emitting diode of the LED display unit.
