Description

  The present invention relates to a pedestal for a photovoltaic power generation module, and more particularly, to a structure capable of collecting heat by integrating a gantry body and a heat medium circulation part through which a heat medium circulates.

  Conventionally, solar power generation systems that generate electric power using solar energy have been put into practical use. A photovoltaic power generation system includes a plurality of photovoltaic power generation modules, a stand for installing these photovoltaic power generation modules on a roof installation surface, etc., and a power line for outputting electric power converted by the plurality of photovoltaic power generation modules to the outside And an inverter. The solar power generation module generally has one power generation panel that receives sunlight and directly converts it into electric power, and a frame that is provided around the power generation panel and supports the power generation panel. doing.

  By the way, the solar power generation module and the solar heat collector described above are not limited to being installed and used alone, but may be used together, but the solar power generation module and the solar heat collector are provided side by side. In this case, since the installation area of the solar power generation module is reduced by the amount of installation of the solar heat collector, there is a possibility that the required power generation amount cannot be achieved.

  In addition, there is a problem in that the appearance is impaired due to the difference in appearance between the solar power generation module and the solar heat collector. In other words, when using a solar power generation module and a solar heat collector in combination, the shape, size, fixed structure, etc. are not necessarily designed in the same way, so the arrangement pattern is limited due to design problems, There is a possibility that various restrictions may arise, such as the necessity of installing each with a different fixing structure, which takes time and increases the cost.

  Therefore, in order not to reduce the amount of power generation due to the reduction in the number of installed solar cell panels, a hybrid panel as in Patent Document 1 may be employed. However, since the hybrid panel generally has a complicated structure and is expensive compared to the photovoltaic power generation module and the solar heat collector, the installation of the hybrid panel increases the cost.

  An object of the present invention is to provide a structure capable of collecting heat while maintaining the amount of power generation without reducing the number of installed photovoltaic power generation modules compared to a conventional photovoltaic power generation system, reducing design value.

Therefore, it is possible to collect heat by simply fixing the solar power module frame to the solar power module mount. be able to. According to this structure, it is possible to easily collect heat from the frame of the solar power generation module, and to cool the solar power generation module. Both efficiency can be improved.

  In addition, since it is possible to make a structure that can collect heat by using the existing solar power module mount, the power generation amount can be maintained without reducing the number of installed solar power modules. A photovoltaic power generation system can be changed from a structure that only generates power to a structure that simultaneously generates power and collects heat. Compared with the case where it is installed side by side with an existing solar heat collector, it is possible to realize a structure that can collect heat with a small installation area and low cost without affecting the number of installed photovoltaic modules, and the appearance is maintained. Therefore, the design value is not impaired.

Is possible.

  According to the invention of claim 3, the plurality of photovoltaic power module mounts are linearly arranged in the longitudinal direction, and the first joint portion is provided at the end of the heat medium circulation portion.
