There is provided a system for cleaning a surface of a solar cell panel. The system includes a measurement unit measuring a power generation value of a solar cell panel, a reference unit providing a reference value, a control unit comparing the power generation value measured at the measurement unit with the reference value provided from the reference unit to command cleaning of the solar cell panel, a driving unit operating a cleaning apparatus for cleaning a surface of the solar cell panel. The control unit commands cleaning of the solar cell panel only when the power generation value decreases because of a contamination of the surface of the solar cell panel.
