NOVELTY - The structure has fixing members (1) with protruding portions in parallel to a portion fixed onto a base material (S) of a building. A cap member pinching fixing portions of an outer surrounding body (2) is arranged in an outdoor side of the fixing members, when the body extends along the protruding portions. A zipper gasket (4) has pinching and fixing portions for holding the protruding and the fixing portions. A photovoltaic power generation panel (3) is fixed between the fixing members by inserting a zipper body into a zipper fitting groove of a gasket main body.    USE - Used for attaching a photovoltaic power generation panel to an outer surrounding body e.g. roof, wall or base material such as balk and roofing board of a building, using a fixing device such as screw and nail, where the photovoltaic power generation panel with solar cells is used for converting an energy of solar beam into an electric power.    ADVANTAGE - The cap member pinching fixing portions of the outer surrounding body is arranged in the outdoor side of the fixing members, when the body extends along the protruding portions so improving the weathering performance. The zipper body is inserted into the zipper fitting groove so improving installation performance. The zipper gasket has pinching and fixing portions in both sides for holding the protruding portions of the fixing members and the fixing portions of the outer surrounding body together so executing wiring for connecting the photovoltaic power generation panels easily without being exposed to an outdoor side of the building and improving a heat insulating effect by forming an air heat insulating layer in the outer side of the building. The photovoltaic power generation outer surrounding structure prevents rain water from entering into an indoor side of the fixing members and an indoor side of the outer surrounding body and also prevents corrosion due to potential difference between different metals from being generated. The photovoltaic power generation outer surrounding structure is easy to install.
