Description

  The present invention relates to a solar cell module and its mounting structure, and a tile material used therefor, and more particularly to a solar cell module installed on an inclined roof, its mounting structure, and a tile material used for installing such a solar cell module. Is.

  In recent years, a photovoltaic power generation system has attracted attention as an electric power system in consideration of the environment. The solar power generation system can meet the power demand of ordinary households by installing solar cell modules on the roof of ordinary houses, and the power generated by solar power generation from the power consumed by each household during the day If the value exceeds the limit, the surplus power can be sold to the electric power company, and it is expected that it will further spread to ordinary households in the future.

  Currently, when introducing a solar power generation system, not only the performance of the solar power generation, but also the motivation to consumers, such as the ease of installation on the roof and the ease of maintenance, etc. Has become important. In solar power generation systems, dozens of solar cell modules (panels) are installed on the roof according to the amount of electric power required by the household. Ensuring safety, ensuring that the solar cell module does not fall off the sloped roof after construction, and ensuring the safety of maintenance work are also socially required, and consumers It will be a decisive factor for whether or not to introduce a solar power generation system.

  Patent Document 1 proposes one technique for simplifying installation of such a solar cell module on the roof and ensuring safety. According to Patent Document 1, first, a necessary number of solar cell units including a plurality of solar cell modules assembled in advance by preparing a detachable solar cell module fixture are prepared. The prepared solar cell unit is lifted on an inclined roof and installed on the roof surface with a wire. Thereafter, a solar power generation system is constructed by connecting the power terminal cables of the respective solar cell units.

  However, this technique requires an additional work in addition to the work of fixing the solar cell unit. That is, in order to connect the power terminal cable, the solar cell module fixture is removed on the inclined roof, the solar cell module is slid, and the solar cell module having a size of about 985 mm × 445 mm is turned over. Stable and cumbersome work is required.

  Also, when a solar cell module is damaged due to bad weather such as a typhoon, or when replacing a solar cell module with degraded performance, such a defective solar cell module is located near the center of the solar cell unit However, there is a restriction that a defective solar cell module cannot be removed unless some normal solar cell modules are removed.

  Therefore, in order to replace a defective solar cell module, the number of solar cell modules temporarily removed from the roof increases on the roof, and the risk of the solar cell module falling from the roof increases. In some cases, safety could be compromised.

  Also, if you try to fix the solar cell module to the roof with wires and try to get the same level of fixing strength to the roof as the tile material, you need to increase the number of wires, when fixing the solar cell module to the roof In some cases, the number of man-hours could increase.

In order to solve such a problem, Patent Document 2 proposes a solar cell module in which the solar cell unit has the same size as the tile material.

  However, in the conventional solar cell module described above, the installation when the solar cell module is attached to the roof becomes simpler and the degree of freedom of layout of the solar cell module is improved, but the connection of the power terminal cable is still easy. There was a problem that was not.

  In addition, when replacing the solar cell unit, there is a problem that the replacement operation is more complicated and difficult than the operation of replacing a normal roof tile.

  The present invention has been made to solve the above problems, and one object is to provide a solar cell module that can be easily and safely installed and maintained on a roof.

In FIG. 1, the external appearance which installed the solar cell module in the inclined roof rolled with the steel plate is shown. For example, a steel plate tile 3 having a size of 350 mm long × 1517 mm wide is laid on the entire sloped roof. In the middle of the inclined roof, for example, the solar cell module 1 having a size of 273 mm long × 1437 mm wide is installed.

  In the solar cell module 1, as shown in FIG. 2, the solar cell module main body 2 is attached to a steel plate roof tile (not shown), and one solar cell module main body 2 is attached to one steel plate roof tile. Each of the steel plate tiles of the solar cell module 1 is attached with a pair of frames 5 and 7 that face each other along a direction orthogonal to the direction of the inclination of the roof. An end portion (lower end) of the solar cell module body 2 is locked to the frame body 5 located on the low inclination side.
