Abstract

PROBLEM TO BE SOLVED: To provide a solar battery module which is superior in appearance and stability and has a function as television reception antenna by installing a reception antenna element on the surface of the solar battery module or a part which becomes blank of the module in constituting a series-parallel circuit. SOLUTION: A solar battery module is constituted of a solar battery 1, a dielectric 2 of glass and the like, an antenna element 3 and an antenna protection layer 4. The antenna element 3 is arranged in a loop form by making it run through the solar battery 1 so that electrical interference between the solar battery 1 and the antenna element 3 can be suppressed to be a minimum. Since the antenna element corresponds to various frequency bands by changing the size and the structure of the antenna element 3, the function of the reception antenna of all the frequencies such as VHF, UHF, BS and CS can be provided. Then, a television antenna affecting the solar battery 1 arranged on a roof can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The invention of this application relates to a solar cell module. More specifically, the invention of this application relates to a solar cell module having a receiving antenna function.

[0002]

2. Description of the Related Art Conventionally, television receiving antennas have been installed upright or overhanging on the roof or roof of a building such as a house, or on a wall surface. In recent years, it has been attempted to dispose solar cells at these sites such as the roof surface. However, conventionally, when both a solar cell and a television receiving antenna are installed on a roof or the like of a house, not only the appearance is impaired, but also a plurality of television receiving antennas, in particular, BS and CS parabolic antennas are installed. In this case, there is a problem that the efficiency of the solar cell is reduced by the shadow of the antenna falling on the solar cell.

Accordingly, an object of the present invention is to provide a new solar cell module which eliminates an object that casts a shadow on a solar cell, is excellent in appearance and stability, and has a function of a television receiving antenna.

[0004]

Means for Solving the Problems The present invention solves the above-mentioned problems. First, the invention has become a margin of the surface of a solar cell module or a module in forming a series-parallel circuit. A solar cell module is provided, wherein a receiving antenna element is provided in a portion.

Secondly, the invention of this application also provides the above-mentioned solar cell module in which a plurality of units are installed and a parallel common-mode circuit is configured.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, the present invention incorporates a television receiving antenna element on the surface of a solar cell module or on a (dummy module) surface or the like in a blank portion of a module generated on a series-parallel circuit configuration, By removing obstacles that cast shadows on the solar cell, it also has a function of a television receiving antenna, and provides a solar cell module with excellent aesthetics and stability. An embodiment will be described.

1 is a sectional view of a solar cell module according to the present invention, and FIG. 2 shows an example of the arrangement of antenna elements on the surface of the solar cell module according to the present invention. As shown in FIG. 1, for example, a solar cell module according to the present invention includes a solar cell (1), a dielectric such as glass (2), an antenna element (3), and an antenna protection layer (4). be able to.

[0010] As shown in FIG. 2, the antenna element (3) is looped through the gap of the solar cell (1) so as not to be an obstacle to the solar cell (1). It shall be arranged in a shape. Or Figure 3
Like As a result, electrical interference between the solar cell and the antenna element can be minimized. Further, by changing the dimensions and structure of the antenna element (3),
VHF, UHF, B to support various frequency bands
It is possible to have the function of a television receiving antenna of all frequencies such as S and CS.

Furthermore, since the solar cell (1) is generally laid along the roof, the direction angle and the inclination angle are not fixed. For this reason, in order to obtain the required gain as a television receiving antenna, the gain can be increased by installing a plurality of similar solar cell modules and forming an appropriate parallel circuit. The present invention provides, for example, a solar cell module having the function of a receiving antenna, which has not been seen before, with the above-described configuration.

When the electric field strength and the visual sense of the VHF antenna were actually measured and evaluated using the solar cell module of the present invention, the measurement was as shown in Table 1 and FIG.

[0011]

[Table 1]

As shown in Table 1 and FIG. 4, the electric field strength of the solar cell module as a VHF antenna almost clears 70 dBμ / m, which is a reference of the receiving characteristic of the antenna, on the right side of the panel without obstacles. You can see that it is doing. Of course, the present invention is not limited to the above examples, and it goes without saying that various aspects are possible.

[0013]

As described in detail above, according to the present invention, a television receiving antenna which casts a shadow on a solar cell installed on a roof is eliminated, and a television receiving antenna excellent in appearance and stability is provided. A new solar cell module having a function is provided.
