Description

  The present invention relates to a solar cell panel support frame and a solar power generation system.

  Solar power generation systems that convert sunlight, which is permanent and clean energy, into electrical energy are rapidly spreading. In addition, solar power generation systems that generate power by installing solar panels on the roofs and roofs of buildings have become widespread, but in recent years, a large number of land such as beach reclaimed land and waste final disposal sites A large-scale photovoltaic power generation system that generates power by arranging and arranging solar cell panels is drawing attention.

  Here, generally, a solar cell panel is installed at a predetermined inclination angle by being attached to a solar cell panel support frame. For example, a concrete base block (base) serving as a counterweight and a plurality of steel materials such as struts, beam materials (hanging lumber), braces (braces), etc., are bolted or welded to the solar cell panel support frame. It is assembled in the shape of a truss or a box frame, and the bottom end of the support is fixed to the upper surface of the foundation block with anchor bolts, and it is equipped with a gantry body that supports the solar panel attached to the beam (For example, refer to Patent Document 1).

JP 2010-98241 A

  On the other hand, in the conventional solar cell panel support frame described above, the foundation block serves as a counterweight, and even when the solar cell panel receives a wind load, the solar cell panel can be stably held to some extent.

  However, in this conventional solar cell panel support frame, since the lower end portion of the column is configured to be fixed to the upper surface of the foundation block with an anchor bolt, the solar cell panel is subjected to wind load and lift force is applied. At this time, this lifting force is received by the tensile force (tensile resistance) of the anchor bolt. That is, since the joining between the support column and the foundation block is a tensile joining, the joining portion is likely to be damaged when a large lifting force is applied during a typhoon or the like.

  Furthermore, in the conventional solar cell panel support frame, for example, a brace is provided to improve the strength and rigidity of the frame body. However, due to the struts, it is difficult for the solar cell panel to enter or exit below the solar cell panel, that is, the inside of the solar cell panel support frame, and the work efficiency when performing maintenance or replacement of the solar cell panel is deteriorated.

The solar cell panel support frame of the present invention has a pair of side surfaces facing in opposite directions and is formed with a predetermined weight, and is erected with a base functioning as a counterweight and a lower end connected to the base. A pair of support columns, and at least one set of panel support frames made of suspended wood that is installed on and supported by the upper end portions of the pair of support columns, and the pair of support columns of the panel support frame includes: , One support column is disposed on one side surface of the pair of side surfaces of the base, and the other support column is disposed on the other side surface with a lower end portion rigidly connected thereto via a fixing bracket. The pair of side surfaces of the base are rigidly joined to each other, and the lower ends of the pair of support columns are detachably rigidly joined to each other.

  Moreover, the photovoltaic power generation system of the present invention converts the above-described solar cell panel support frame, the solar cell panel attached to the solar cell panel support frame, and DC power obtained from the solar cell panel into AC power. And a DC / AC converter.

  In the solar cell panel support frame and the photovoltaic power generation system of the present invention, the lower end of one column is rigidly joined to one side of the base, and the lower end of the other column is rigidly joined to the other side of the base. A panel support frame of the battery panel support frame is formed. For this reason, the joining part of the support | pillar and base | substrate which a solar cell panel receives a wind load and a lift force acts becomes a shear bond, and it becomes possible to improve the intensity | strength with respect to a lift force, and a rigidity more reliably than the conventional tension joining. .

  Further, since the pair of support columns are rigidly joined to the base, the rigidity of the panel support frame made of the pair of support columns and the hanging lumber can be increased without using braces. Thereby, the solar cell panel can easily enter and exit the lower space, and the workability such as maintenance and replacement of the solar cell panel can be greatly improved. Furthermore, since it is possible to easily go into and out of the lower space of the solar panel without the need for bracing, it becomes possible to install equipment such as a DC / AC converter on the base, for example, below the solar panel. Space can be used effectively.
