  The membrane material 12 is a roof material attached to the roof of a building (not shown), and is used for a tent, a dome-type roof material, or the like. The membrane material 12 is formed by forming a fluororesin film excellent in oil repellency and water repellency on the surface of a base fabric woven with glass fibers or fibers made of synthetic resin such as polyamide or polyester. The fluororesin film formed on the surface of the film material 12 makes it difficult for dirt to adhere to the surface of the film material 12 and is excellent in durability. The membrane material 12 expands and contracts in the surface direction (including both the in-plane direction and the out-of-plane direction) by an external force such as an internal pressure of the building or a wind blown to the outside of the building. That is, the membrane material 12 is constructed while introducing initial tension at the time of construction. In addition, after construction, tension is applied by external forces such as wind, thermal expansion, snow accumulation, and accumulated water, and the surface expands and contracts. In the present embodiment, the film material 12 is configured to extend by, for example, a maximum of about 5%.

  The solar cell module 14 is a sheet-like member having flexibility, and a thin film solar cell is disposed on a resin film substrate having electrical insulation properties such as polyimide, and the surface of the solar cell (light receiving) together with an electrode. Surface) is coated with a light-transmitting protective film. The solar cell and the film substrate, and the solar cell and the protective film are bonded with an adhesive. The solar battery cell is composed of a photovoltaic device such as crystalline Si, polycrystalline Si, amorphous Si, or CIGS compound semiconductor. The solar cell module 14 can be bent with an arbitrary curvature. In this embodiment, the solar cell module 14 is formed in a substantially rectangular shape. For example, the length is 3500 to 6000 mm, the width is 350 to 500 mm, and the thickness is 1 to 10 mm. In addition, the dimension of the solar cell module 14 is not limited to this. Moreover, in this embodiment, the tensile strength of the vertical direction of the solar cell module 14 is about 1400-1500 N / cm, and the tensile strength of the horizontal direction is about 1100-1200 N / cm.

And a pair of horizontal frame members 20 arranged. A substantially rectangular frame edge member 16 is formed by arranging both ends of the pair of vertical frame members 18 and both ends of the pair of horizontal frame members 20 in contact with each other in plan view. In this embodiment, since the film | membrane material 12 expands / contracts in a surface direction, the both ends of a pair of vertical frame material 18 and the both ends of a pair of horizontal frame material 20 are not connected. The frame edge member 16 is made of, for example, resin or rubber.

  As shown in FIG. 2, the pair of vertical frame members 18 of the frame edge member 16 is a substantially “U” -shaped member arranged symmetrically, and an opening of the approximately “U” -shaped member is formed. It arrange | positions so that it may face the solar cell module 14 side. The pair of vertical frame members 18 are bent inward in the width direction from the upper wall portion 18A, the vertical wall portion 18B bent downward from the width direction end portion of the upper wall portion 18A, and the lower end portion of the vertical wall portion 18B. And a lower wall portion 18C.

  The lower wall portion 18 </ b> C of the vertical frame member 18 is bonded (adhered and fixed) to the surface of the film material 12 with an adhesive 22. The distance between the inner end faces of the pair of vertical frame members 18 is set to be shorter than the width of the solar cell module 14, and the edges on both sides in the width direction of the solar cell module 14 are inside the pair of vertical frame members 18. It is inserted and supported while being sandwiched between a pair of vertical frame members 18.

  The edge of the solar cell module 14 is held between the inside of the vertical frame member 18, that is, between the edge on both sides in the width direction of the solar cell module 14 and the inner wall surface of the vertical frame member 18. The pressure-sensitive adhesive 24 for suppressing the detachment is filled. As the adhesive 24, for example, a low-viscosity silicone resin or an elastomer is used.

  Although not shown in the drawings, the pair of horizontal frame members 20 on both sides in the longitudinal direction of the frame edge member 16 are substantially “U” -shaped members arranged symmetrically, and like the vertical frame member 18, the upper wall 20A, a vertical wall portion bent downward from the outer end portion of the upper wall portion 20A, and a lower wall portion bent inward in the width direction from the lower end portion of the vertical wall portion (FIG. 2). See).

  A lower wall portion of the horizontal frame member 20 is fixed to the surface of the film member 12 by an adhesive 22. The distance between the inner end faces of the pair of horizontal frame members 20 on both sides in the longitudinal direction is set to be shorter than the length in the longitudinal direction of the solar cell module 14, and the edges on both sides in the longitudinal direction of the solar cell module 14 are a pair. It is inserted into the horizontal frame member 20 and supported while being sandwiched between a pair of vertical frame members 18.

  The edge of the solar cell module 14 is held inside the horizontal frame member 20, that is, between the edges on both sides in the longitudinal direction of the solar cell module 14 and the inner wall surface of the vertical frame member 18. The pressure-sensitive adhesive 24 for suppressing the detachment is filled.

  The vertical frame member 18 and the horizontal frame member 20 that constitute the frame edge member 16 are supported by the periphery of the solar cell module 14 so as to be movable, and are restricted members that limit the amount of movement of the solar cell module 14.

  Since the fluororesin coating on the surface of the film material 12 has poor adhesion, the lower wall portion 18C of the vertical frame material 18 and the lower wall portion of the horizontal frame material 20 are bonded and fixed to the surface of the film material 12 with an adhesive 22. When doing so, it is preferable to perform the surface treatment of the fluororesin coating on the adherend portion of the membrane material 12 in advance. Surface treatment methods include chemical treatment methods using potassium dichromate, metallic sodium and sodium-naphthalene complexes, methods using corona discharge, plasma discharge, sputter etching and other discharge treatments, and irradiation with an argon fluoride excimer laser. A processing method or the like is used. The surface treatment method for the fluororesin coating is described in JP-A-2007-33085.

  As the adhesive 22, a reaction curing type adhesive, a hot melt type adhesive, or the like is used. For example, an epoxy adhesive, a phenol adhesive, a bromine adhesive, an acrylic-modified silicone adhesive, a butyl rubber adhesive, or the like is used. Instead of the adhesive 18, a rubber-based or acrylic resin-based pressure-sensitive adhesive may be used.

  As shown in FIG. 1, a plurality of solar cell modules 14 are arranged side by side in the horizontal direction and the vertical direction of the surface of the film material 12, and the plurality of solar cell modules 14 are each formed of the film material 12 by a frame edge material 16. It is supported so as to be movable with respect to the surface. Although illustration is omitted, wiring is connected to the electrode provided inside the solar cell module 14, and wiring processing is performed so that the wiring is drawn inside the frame edge member 16 and connected to an external power source. ing.

  When the solar cell module 14 is attached to the surface of the film member 12, the vertical frame member 18 corresponding to three sides, leaving one side of the vertical frame member 18 and the horizontal frame member 20 constituting the frame edge member 16, and The horizontal frame member 20 is bonded in advance to the surface of the film member 12 with an adhesive 22. And the edge part of the solar cell module 14 is inserted in the vertical frame material 18 and the horizontal frame material 20 corresponding to 3 sides. Thereafter, the remaining vertical frame member 18 or horizontal frame member 20 is extrapolated to the edge of the solar cell module 14, and the vertical frame member 18 or horizontal frame member 20 is attached to the surface of the film member 12 by the adhesive 22. The attachment of the solar cell module 14 is completed by bonding.

As shown in FIG. 2B, the membrane material 12 attached to the roof of the building (not shown) expands and contracts in the plane direction (in-plane direction and out-of-plane direction) by external force such as internal pressure or wind of the building. When this occurs, the vertical frame member 18 and the horizontal frame member 20 move due to the expansion and contraction of the film member 12, whereby the peripheral portion of the solar cell module 14 and the vertical frame member 18 and the horizontal frame member 20 move relatively. For this reason, the solar cell module 14 does not follow the expansion and contraction of the film material 12, and the generation of distortion of the solar cell module 14 is suppressed. For this reason, damage to the solar cell module 14 can be prevented. FIG. 2B shows a state in which the film material 12 is extended in the surface direction.

  Further, since the movement amount of the solar cell module 14 is limited by the frame edge member 16, the solar cell module 14 does not leave a predetermined position on the surface of the film material 12.

  For example, the film material 12 may extend up to about 5%, and the solar cell module 14 may break the power generation element with a strain of about 2 to 3%, and the power generation capacity may be reduced. The peripheral portion of the solar cell module 14 and the vertical frame member 18 and the horizontal frame member 20 move relative to each other, so that generation of distortion of the solar cell module 14 due to expansion and contraction of the film member 12 is suppressed. For this reason, it is possible to prevent the solar cell module 14 from being damaged and the power generation capacity from being lowered.
