  However, in Patent Document 1, since the power supplied from the solar power generation device is only supplied from the solar cell in a limited area called the curved roof portion above the wind power generation device, the power supply amount is naturally limited. Yes, it can only be supplied to the attic space at best. In addition, since the wind power generator is supported by the support structure and protrudes from the roof surface, it is difficult to obtain effective wind power than turbulent flow or surrounding wind power, and the power supply by the wind power generator is limited. is there. In addition, since the support structure is required on the roof surface, there is a problem that the appearance of the building is damaged.

  Moreover, when a solar cell of a photovoltaic power generation apparatus is installed with a maximum area on the roof surface in a general building, there are the following problems. The roof shape considering the optimum power generation efficiency of the solar power generation device is, for example, a triangular roof with a slope of 30 ° to 35 ° on the south side or a single flow, but if the power generation capacity is 5 kW, 6 kW, 7 kW, it is installed on the entire surface of the single flow roof In addition, the roof area will be increased. Therefore, the height of the roof top and the maximum height of the building are increased, and there is a problem that, when a building is arranged on the north side or the road side in a narrow site or the like, it is restricted by the oblique line in the Building Standard Law.

It is characterized by becoming.

  The invention according to claim 5 is characterized in that, in claim 3, the sloped roof has a curved surface only on the roof surface around the ridge, and is formed as an inclined surface from the eaves to the curved surface. And The invention according to claim 6 is the invention according to claim 5, wherein the curved surface is formed only on one side of the roof surface, and the other side of the roof surface is formed on an inclined surface having the same inclination as the inclined surface. It is characterized by that.

To do. The invention described in claim 8 is characterized in that, in claim 7, the windmill is a vertical axis windmill.

  The present invention is as described above, wherein the roof surface is a sloped or curved slope roof, a plurality of solar battery panels are installed on the roof surface of the sloped roof, and the wind turbine generator is installed near the top of the roof surface. Since the windmill is located, both the solar power generation device and the wind power generation device can take a larger amount of power supply by the power generation than the conventional one, and can use natural energy to the maximum. it can. Moreover, since a support structure is not required as in the prior art, the appearance of the building is not impaired. In addition, it is possible to expect an excellent effect that it can be implemented even in a small site or the like without being restricted by the oblique line in the Building Standard Law.

  Embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a front view of a building having both a solar power generation device and a wind power generation device, FIG. 2 is a side view thereof, and FIG. 3 is a plan view thereof. 1 is a two-story building with a flat roof, and has a one-sided gradient roof 2 facing the south surface. The roof surface of the sloped roof 2 is formed into a gently curved surface 3 at predetermined height intervals from the eaves to the ridge. A plurality of solar battery panels 5 are arranged on almost the entire curved surface 3 so as to be arranged vertically and horizontally from near the eaves of the sloped roof 2 to near the ridge. In this example, as is apparent from FIG. 3, a total of 49 solar cell panels 5 of 7 × 7 are installed. Although details are not shown when installing the solar cell panel 5, the upper and lower parts of the frame of the panel are supported by a gantry fixed in parallel to the vertical direction of the roof surface.

  That is, in consideration of the power generation efficiency of sunlight, the solar cell panel 5 has a first row of solar cell panels 5 near the eaves having a gradient of 35 ° with respect to the horizontal plane, and the second row of solar cell panels 5 is 1 A gradient of 2 ° to 3 ° is given to the solar cell panels in the row, and the solar cell panels 5 in the third row and thereafter are also similarly sloped to the solar cell panel 5 in the last row near the ridge. And supported by the mount. The slope of the solar cell panels 5 in the first row is preferably about 30 ° in consideration of the maximum efficiency in summer, but is set to 35 ° from the viewpoint of not reducing the power generation efficiency throughout the four seasons. However, this is merely an example, and an arbitrary angle in the range of 20 ° to 40 ° may be used, and an arbitrary angle in the range of 24 ° to 35 ° is preferable.

  The solar cell in the solar cell panel 5 directly converts the radiant energy of solar rays into electric energy efficiently and stores it in a solar power generation device (not shown). In this example, the roof surface is the curved surface 3 as described above, but this may be a surface inclined in a gentle step shape. The solar cell panel 5 is supported on the inclined surface by the gantry and installed with the above-described gradient.

  A flat roof 7 is formed adjacent to the opposite side of the ridge of the sloped roof 2 thus formed so as to be lower than the ridge, and a wind power generator 8 is attached to the upper part of the support tower 9 on the flat roof. The wind turbine 10 is installed near the ridge. The windmill 10 is a vertical axis windmill, and flows upward from the eaves of the sloped roof 2 along the roof surface as indicated by an arrow in FIG. 1 so as to efficiently receive and rotate the wind concentrated right above the ridge. It has become. Then, the wind energy generated by the rotation of the windmill 10 is directly and efficiently converted into electric energy, which is stored in the wind power generator 8. The installation position of the wind power generator 8 may be anywhere on the flat roof 7. The windmill 10 may be a horizontal axis windmill.

  Since it is configured as described above, the solar cell radiant energy is converted into electric energy by the solar cell in the solar cell panel 5, and it is stored in the solar power generation device, and the place required by the building On the other hand, the wind energy is converted into electric energy by the rotation of the windmill 10, which is stored in the wind power generator 8, and is also used as the power of the place that the building requires. In this way, it is possible to increase the amount of power supplied by the power generation as compared with the conventional one, and natural energy can be utilized to the maximum extent. In particular, since the roof surface is composed of the curved surface 3, the wind speed near the ridge that is the roof top is increased, the rotation of the windmill 10 is increased, and a wind speed (force) higher than the surrounding wind speed can be obtained.

  In addition, the maximum height of the roof surface can be suppressed even with the same solar power generation capacity, and the height can also be suppressed by installing the wind power generator 8 on the flat roof 7 on the opposite side to the ridge. Moreover, since the installation of the wind power generator 8 can be performed on the flat roof 7, the work and the maintenance work after installation become easy. Moreover, although the support tower 9 is used for the installation, the cost is much lower than that of the conventional support structure, leading to cost reduction of the members.

  Further, only the wind turbine 10 of the wind power generator 8 protrudes from the roof surface, and does not significantly protrude from the roof surface unlike a conventional support structure, so that the appearance of the building is not impaired. Moreover, since the wind power generator 8 is installed on the flat roof 7 formed at a position considerably lower than the roof surface, it is not subject to the oblique line restriction in the Building Standard Law even in a small site.

  4 and 5 show another embodiment, FIG. 4 is a perspective view of the roof portion, and FIG. 5 is a front view of the roof portion. This embodiment is basically different in that the gradient roof of the above embodiment is a single-flow roof, but is a gable roof provided with a gradient roof on the opposite side. That is, the sloped roof 12 is formed on a surface 13 in which the roof surface from the ridge to the eave in the opposite direction is continuously curved in addition to the ridge to the ridge. The gradient of the roof surface at the ridge is almost equal. The flat roof 17 on which the wind power generator 18 having the windmill 20 is installed by being supported by the support pole 19 is slightly biased to the opposite side. In this example, the roof surface may be an inclined surface. In the building having such a configuration, wind force from the roof surface on the opposite side can be efficiently received by the windmill 20, and the power generation efficiency can be further increased. Although the solar cell panel of the solar power generation apparatus is not shown, it is installed in the same manner as in the above embodiment. Furthermore, in this embodiment, the solar cell panel can be installed on the roof surface on the opposite side or may not be installed.

  6 and 7 show still another embodiment, FIG. 6 is a perspective view of the roof portion, and FIG. 7 is a front view of the roof portion. In this embodiment, the sloped roof is a single-flow roof, but is basically different from the above embodiments in that the shape of the roof part is partially different. That is, the sloped roof 22 is a curved surface 23 only on the roof surface around the ridge, and is formed as a sloped surface 24 from the eaves to the curved surface. Even with such a configuration, the same effect as that of the nuclear embodiment can be expected. Although the solar cell panel of the solar power generation apparatus is not shown, it can be installed on the inclined surface 24 in this example as well, and can also be installed on the curved surface 23. In the case where the solar cell panel is installed only on the inclined surface 24, the solar cell panel can be installed more easily than the curved surface 23, and the curved surface 23 is exposed. It improves and wind power generation efficiency increases. Reference numeral 27 denotes a flat roof on which the wind power generator 18 is installed.

  FIG. 8 is a modification of the embodiment of FIGS. 6 and 7, in which the curved surface 33 is formed only on one side from the center of the roof surface, and the other side of the roof surface is continuous with the inclined surface 24. It is formed on the inclined surface 34 of the same inclination. In this example, the wind power generator 38 is installed on the flat roof 37 corresponding to the curved surface 33 with the windmill 40 positioned near the ridge. This form is suitable for buildings where solar power generation is more important than wind power generation, and it is possible to install solar cell panels using the entire inclined surfaces 24 and 34. Even with such a configuration, the same effect as that of the nuclear embodiment can be expected.

  Each of the embodiments described above is merely a preferable example. The shape of the sloped roof 2, the number of solar cell panels 5 installed therein, whether the roof is single flow or double flow, the wind power generator 8, The installation location of 18, 38, the type of wind turbine 10, 20, 40 (whether it is a vertical axis wind turbine or an aquatic axis wind turbine), etc. are appropriately changed according to the technical matters described in the claims at the time of implementation. can do.
