Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balcony with solar panels, in which solar panels are mounted outside the handrails of the balcony.

[0002]

2. Description of the Related Art Conventionally, a solar cell panel mounted on a building is disclosed, for example, in Japanese Unexamined Patent Publication No. 9-96071, in which a gantry is assembled on a roof of a building and a plurality of solar cell panels are arranged on the gantry. Things are known. However, when the solar cell panel is mounted on the roof, the ladder must be used for cleaning and repair, and the maintenance work is difficult. In addition, the installation work of the solar cell panel also needs to be performed on the roof similarly, which has a disadvantage that it takes a large scale. As a specific means for solving this problem, a balcony with a solar cell panel is described in JP-A-10-219814. In the case of this balcony with a solar cell panel, a plurality of solar cell panels are attached to the outer wall surface of the balcony of the apartment house at a predetermined angle.

[0003]

However, in the case of the balcony with a solar cell panel disclosed in JP-A-10-219814, rain that falls on the surface of the solar cell panel flows down the inclined surface of the solar cell panel and causes the sun to fall. Because it falls directly from the bottom of the battery panel to the ground,
There is a problem of giving discomfort to passers-by and the like.

[0004] The present invention has been made in view of the above-mentioned problems, and has as its object to provide a balcony with a solar cell panel in which rainwater does not fall directly to the ground from the solar cell panel during rainfall.

[0005]

According to the first aspect of the present invention, there is provided a balcony with a solar cell panel having a solar panel mounted outside a handrail of the balcony. An eave provided with an eaves gutter is provided below the lower end, and rainwater flowing down from the solar cell panel during rainfall is made to flow into the eaves gutter with the solar cell panel It is a balcony.

In the present invention, as means for allowing rainwater flowing down from the solar cell panel to flow into the eaves gutter, an eaves gutter is provided below the lower end of the solar cell panel so that the rainwater flowing down falls. May be directly received, or rainwater flowing down by a water guide plate or the like may be guided to an eaves gutter. Also, a gutter may be provided at the lower end of the solar cell panel to collect rainwater that has flowed down before guiding it to the eaves gutter.

According to a second aspect of the present invention, there is provided a balcony with a solar cell panel having a solar cell panel attached to the outside of a handrail of a balcony, wherein an eaves gutter is provided below a lower end of the solar cell panel. An eave is provided, and a slit-shaped water guide hole is provided across a width direction of the solar cell panel between a lower end of the solar cell panel and an upper end of the eave. A balcony with a solar cell panel, wherein rainwater flowing down a battery panel flows into the eaves gutter through the water guide hole.

According to a third aspect of the present invention, in the second aspect of the present invention, the water guide plate extends in the width direction of the solar cell panel between the upper end of the eave forming the water guide hole and the eaves gutter. Is a balcony with a solar panel.

[0009] The invention described in claim 4 is the first invention.
In the invention according to the second or third aspect, the handrail is formed of a handrail panel, and the handrail panel is provided with an inspection port.
Here, it is preferable from the viewpoint of design and safety to provide the inspection opening with a lid that can be opened and closed and detachable.

The balcony according to the first to fourth aspects of the present invention may be provided so as to protrude from the outer wall of the building, or may be provided on the roof of the building. Further, the eaves gutter may be provided as a separate component from the eaves main body, or may be formed integrally with the eaves main body. Claims 1 to 4
In the solar cell panel according to the present invention, it is preferable that a drain is provided at the lower end because rainwater flowing down the solar cell panel can be effectively guided to the eaves gutter. In addition, when the solar cell panel is formed integrally with the handrail of the balcony, the solar cell panel can be used as a structural element of the handrail. Furthermore, since the solar cell panel is attached to the outside of the handrail, it is preferable to provide the solar cell panel with a somewhat large angle in order to effectively use the floor area of the balcony. Specifically, 45 ° or more is preferable. In order to effectively utilize solar energy, the angle is preferably 90 ° or less. Even when the angle of the solar cell is close to 90 °, if the wind blows during rainfall, rainwater may adhere to the surface of the solar cell panel and flow down. Therefore, it is necessary to take measures against rainwater fall.

[0011]

In the balcony with solar panels according to the first aspect of the present invention, an eave with an eaves gutter is provided below the lower end of the solar panel, and rainwater flowing down from the solar panel during rainfall is provided. Flow into the eaves gutter. Therefore, the rainwater flowing down the surface of the solar cell panel and flowing down the solar cell panel does not fall directly to the ground from the lower end of the solar cell panel.

[0012] In the balcony with the solar cell panel according to the second aspect of the present invention, a slit-shaped water guide hole is provided between the lower end of the solar cell panel and the upper end of the eaves in the width direction of the solar cell panel. In addition, rainwater that has flowed down from the solar cell panel during rainfall flows into the eaves gutter through the headrace hole. In other words, by the slit-shaped water conduit,
Foreign matter such as fallen leaves can be prevented from flowing into the eaves gutter together with rainwater.

In the balcony with the solar cell panel according to the third aspect of the present invention, a water guide plate is provided across the width of the solar cell panel between the upper end of the eaves forming the water guide hole and the eaves gutter. Therefore, the rainwater flowing down the inclined surface of the solar cell panel can be reliably guided to the eaves gutter.

In the balcony with a solar panel according to the fourth aspect of the present invention, the handrail is formed of a handrail panel, and the handrail panel is provided with an inspection port. Therefore, maintenance such as cleaning of the eaves gutter and maintenance of the back surface of the solar cell panel can be easily performed from the inside of the balcony using the inspection port.
