Mount for solar cell module, and photovoltaic power generation system using the mount

Abstract

A frame member (21) of a solar cell module (2) is fixed and supported by being sandwiched between a lower fixture (4) and an upper fixture (3a). A protrusion (44a) on an upper plate (40) of the lower fixture (4) is pressed to the surface of the frame member (21) of the solar cell module (2). When a bolt (8) is tightly fastened, the upper plate (40) and the frame member (21) are brought into strong contact with each other with pressure, and the protrusion (44a) on the upper plate (40) enters the surface of the frame member (21) of the solar cell module (2) and permits electricity to be carried.

Description

technical field [0001] The present invention relates to a base for fixing and supporting a solar cell module and a solar power generation system using the base. Background technique [0002] Usually, when a solar cell module is installed on a roof or the like, a base for the solar cell module is mounted on the roof or the like, and the solar cell module is placed on the base and fixed. On the other hand, the charged charge is grounded, and the frame structure of the solar cell module and the like are connected to the ground through wiring. [0003] However, since the frame structure of the solar cell module formed of a conductive metal body is provided with an insulating film for corrosion protection, the work of wiring the ground wire of the solar cell panel is cumbersome. In contrast, there has been proposed a solar cell panel mounting base in which the ground wire is grounded easily and reliably. [0004] For example, Patent Document 1 describes a technique of providing...

[0006] However, as in Patent Document 1, the tiny protrusions that support the solar cell panel on the base without looseness are weak, and when the frame is pressed from above, the protrusions may become distorted before they sink into the frame.

Or, when the position of the frame of the solar cell module is adjusted after falling into the frame, or the frame of the solar cell module is shifted by collision, the micro-protrusions are skewed or crushed, and the solar cell module and the micro-protrusions cannot be stabilized. electrical connection

[0007] For example, when an aluminum material is used for the frame of a solar cell module, an insulating oxide film is formed on the surface of the aluminum. In the state where the oxide film on the surface is in contact, it becomes difficult to conduct conduction via the solar cell module frame with tiny protrusions
