Description

The present invention relates to an appliance for installing a photovoltaic power generation panel inside a window glass at an angle with respect to a glass surface.

Although pedestals and appliances for collectively installing photovoltaic power generation panels on the roof or on the ground are widely known, small photovoltaic power generation panels with a power generation capacity of 10 watts, etc. are directed toward the south side where power generation efficiency is good. There is no known device for tilting indoor installation such as window glass.
Large-scale construction such as making holes in the wall and wiring is required to install the photovoltaic power generation panel outdoors and connect it to indoor equipment, but in condominiums and rental houses, it is necessary to install it on the wall. It is often impossible to perform drilling.
Therefore, in order to use small-scale solar power generation at home, the solar power generation panel must be hung on a window or laid on the floor.

The energy of sunlight passing through the window glass is attenuated due to light absorption and scattering by the glass, and there is a problem that sufficient photovoltaic power generation cannot be expected unless light is received at an appropriate angle. In addition, there is a problem that an appropriate place for installing a photovoltaic power generation panel cannot be secured indoors due to window curtains and obstacles in the room.

Provided is an installation fixture configured to maintain an appropriate angle with respect to sunlight by tilting a photovoltaic power generation panel on the indoor side of a window glass.

It is possible to configure a small-scale photovoltaic power generation system that is not affected by curtains or obstacles in the room. By installing one side of the photovoltaic power generation panel in close contact with the window glass and installing it in parallel, it is possible to minimize the swelling of the photovoltaic power generation panel from the glass surface into the room.

It is the figure which looked at this instrument from the side. (Beside the window glass) It is the figure which looked at this appliance from the front (the front of the room side with respect to the window glass). A diagram in which a photovoltaic power generation panel is mounted on this device, and the angle between the pedestal portion 3 and the arm portion 2 is changed only in the vertical direction by the connection angle variable portion 4 as an example in the direction of the sun with the fixing portion 1 fixed to the window glass. Is. FIG. 3 shows an example in which the window facing south is installed at an elevation angle of about 45 degrees. It is a figure which shows the case where this apparatus is installed on the window glass at an elevation angle of about 45 degrees outside the room by rotating the connection angle variable part 4 45 degrees to the opposite side from the example shown in FIG.

FIG. 1 shows the configuration of this device.
It is an instrument for installing the photovoltaic power generation panel on the indoor side of the window glass at an angle toward the sun, and for fixing the fixing portion 1 for fixing the appliance to the window glass and the photovoltaic power generation panel. The pedestal portion 3 of the above, the arm portion 2 for directing the photovoltaic power generation panel of the pedestal portion 3 toward the window glass fixing surface side of the fixing portion 1, and the pedestal portion 3 and the arm portion 2 by the connection angle variable portion 4. It is a photovoltaic panel installation device that is configured so that the connection angle of the can be changed.
The length of the arm portion 2 connected to the pedestal portion 3 so that the photovoltaic power generation panel does not hit the window glass is adjusted so that the arm portion 2 does not protrude from the window glass fixing surface of the fixing portion 1.
Basically, the fixing portion 1 is used at a position lower than the pedestal portion 3 so as not to cast a shadow on the photovoltaic power generation panel on which the arm portion 2 and the fixing portion 1 are mounted.
The fixing portion 1 may be fixed to the glass window by using a suction cup, or may be fixed by using an adhesive tape or an adhesive when the possibility of changing the fixing position is low.
The pedestal portion 3 has a photovoltaic power generation panel holding portion for mounting and fixing the photovoltaic power generation panel. The photovoltaic power generation panel holding portion has a U-shaped pressing groove for pressing the photovoltaic power generation panel and a screw mechanism for gripping. The panel may be gripped by one or a plurality of known fixing methods such as a mechanism using a spring or rubber, a suction cup, an adhesive tape, an adhesive, and screwing.
As shown in FIG. 1, the photovoltaic power generation panel can be fixed by providing a U-shaped presser groove at the two ends (lower left and upper right in FIG. 1) of the pedestal portion 3, and the pedestal portion 3 can be fixed as shown in FIG. It can be fixed stably even if it is turned upside down. A U-shaped holding groove may be provided at the tip of a rod-shaped appliance built in the pedestal portion 3 according to the width of the photovoltaic power generation panel, and the solar panel may be fixed by expanding and contracting.
The pedestal portion 3 and the arm portion 2 are provided with a connection angle variable portion 4 capable of changing the connection angle so that sunlight efficiently hits the photovoltaic power generation panel. The variable connection angle portion 4 is a combination of a circular ball and a ball grip portion, a combination of horizontal and vertical rotation mechanisms such as a camera tripod, and a pedestal portion 3 and an arm portion 2 by a known method such as a flex arm. The connection angle of may be variable in the horizontal plane and the vertical plane.
By setting the connection angle of the connection angle variable portion 4 to the opposite side of 3 as shown in FIG. 4 (the elevation angle of 45 degrees in FIG. 3 is set to -45 degrees in FIG. 4), even on the outdoor side of the window glass. It can be an appropriate elevation angle (eg 45 degrees) with respect to the sun.
In recent years, low-power devices such as smartphones, cameras, and music devices are often charged by USB connection, and many small mobile batteries for USB charging are also on sale. The solar power generation panel that generates electricity with 5 volts for USB is several hundred grams, and the size is about 30 cm or less on the long side, and it is lightweight and compact. Therefore, it is convenient in terms of convenience that the photovoltaic power generation panel and the battery can be installed in the vicinity. Therefore, an instrument for accommodating the mobile battery may be provided in the pedestal portion 1, the arm portion 2, or the pedestal portion 3.
Since the photovoltaic power generation panel has a power supply (USB, etc.) on the back side and interferes with fixing on the pedestal part, the pedestal part 3 has a central part empty as shown in FIG. 2 so that the power cable can be passed through. You may.
The connection angle between the pedestal part 3 and the arm part 2 (the angle of the variable connection angle part 4) is the horizontal line depending on the latitude where the house is located, the elevation angle at mid-south of the sun, the line perpendicular to the window glass surface, and the south direction. The appropriate angle can be obtained from the horizontal angle formed.
For example, in Tokyo, the maximum elevation angle of the sun in January is about 30 degrees, the maximum elevation angle of the sun in August is about 80 degrees, and the annual average optimum elevation angle for power generation is about 30 degrees. The connection angle of the variable connection angle portion 4 (vertical direction: the angle formed by the pedestal portion 3 and the window glass on the vertical surface minus 90 degrees (elevation angle)) is set so as to be the angle of these maximum elevation angles, and is set in the horizontal direction. (Angle formed by the pedestal portion 3 and the horizontal plane of the window glass) is set to zero (parallel). Furthermore, the vertical angle can be determined in consideration of the latitude (43 degrees Hokkaido 38 degrees Sendai, 35 degrees Tokyo, 26 degrees Okinawa, etc.). Since it is generally troublesome to change this angle frequently depending on the season, the optimum elevation angle of 30 degrees may be set for the whole year. If the building position of the house (the direction in which the window faces) is not in the southward direction, the horizontal angle of the connection angle variable portion 4 is changed according to the angle in the horizontal plane formed by the windowpane with respect to the south, and the windowpane is used. Install. For example, when a house is constructed at an angle of 90 degrees east of the south (windows facing east), the sunlight that hits the photovoltaic panel within the time from sunrise until the windows are no longer exposed to direct sunlight. To maximize. For example, if the solar panels are fixedly installed throughout the year, the sun will be set at the midpoint (9:00 am) around 12:00 when the direct sunlight will stop from sunrise (around 6 o'clock in Tokyo), with the spring equinox day as the standard. The pedestal portion 3 (photovoltaic panel) is oriented and fixed in a direction of an elevation angle of 34 degrees and a horizontal plane of 60 degrees from the south. Similarly, when the house is constructed with an inclination of 90 degrees to the west with respect to the south, or when the house is inclined to 30 degrees, 45 degrees, or 60 degrees to the east and west, the optimum elevation angle and the south in the horizontal plane. The angle from can be calculated. Based on this, the connection angle of the connection angle variable portion 4 can be adjusted. For example, the vertical tilt angle of the pedestal portion 3 is limited to 3 stages (for example, 30 degrees, 60 degrees, 80 degrees), and the horizontal angle is limited to 5 stages (for example, 0 degrees, east-west 45 degrees, east-west 90 degrees). However, marks and protrusions can be added to the optimum positions of the connection angle variable portion 4 according to the angle in the horizontal plane formed by the window glass with respect to the south and the sun elevation angle (latitude, season, etc.). For example, in the case of a rotating mechanism that uses a circular ball and a grip, the season (summer, winter, spring / autumn, year-round) and the direction of the window (south, east-west 30 degrees, east-west 45 degrees, east-west 60 degrees, east-west 90 degrees) By putting a mark or protrusion on the circular ball at the optimum position (one point on the sphere) corresponding to, the connection angle variable part 4 can be set as the optimum position, and the solar power generation panel can be installed at the optimum horizontal and vertical angles. it can. The angle can be fixed by stopping the rotation of the circular ball with a pin or screw according to the mark or protrusion of the circular ball.

The present invention relates to an installation device for indoor use of a small-scale photovoltaic power generation panel, and the photovoltaic power generation panel can be installed on a window glass at an optimum inclination in the direction of the sun, for an apartment, a rental house, or the like. The effect of accelerating the installation of small-scale photovoltaic power generation panels can be expected.
