PURPOSE: A sound proof wall is provided to facilitate installation, maintenance and repair by arranging a sound proof panel between sound absorbing units and to perform solar power generation of high efficiency by preventing damage due to external force. CONSTITUTION: A sound proof wall capable of generating solar power comprises a sound absorbing unit(120) and a sound proof panel(130). A pillar is separately placed with a predetermined interval. The sound absorbing unit is arranged between pillars, and the sound proof panel is arranged between the sound absorbing units. The sound proof panel is movably coupled between the sound absorbing units, relieves external pressure like wind pressure, and enables separation and replacement. The sound proof panel includes a photovoltaic module in one or more side; a front side, a sound proof layer and the photovoltaic module. The front side and the sound proof layer improve efficiency of a solar cell by attaching an optical sheet or an optical film. |
