PROBLEM TO BE SOLVED: To provide an acoustical panel with a solar cell panel, from which a wire transmitting electric power generated by the provided solar cell can be easily lead to the outside.SOLUTION: Frame materials are attached to four sides of a quadrilateral sound insulation plate equipped with a solar cell, respectively, a recessed groove recessed to the inner side of the frame material is formed along the longitudinal direction of the frame material over its entire length, an end part of the sound insulation plate is inserted into and attached to the recessed groove, and a wire transmitting electric power generated by the solar cell is arranged along the end part of the sound insulation panel and stored in the recessed groove. Since the wire transmitting electric power generated by the solar cell is arranged along the end part and stored in the recessed groove formed over the entire length of the frame material, the wire is easily wired to the outside of the frame material. |
