Outer surrounding structure of photovoltaic power generation system

Abstract

To improve weathering and installation performances, a photovoltaic power generation outer surrounding structure comprises a plural long fixing members (1) having protruding portions (1b) in both sides in parallel to a portion (1a) fixed onto a base material (S) of a building, an outer surrounding body (2) arranged on the base material (S) between the fixing members (1, 1) and having fixing portions (2a) extending under the protruding portions (1b) in both ends, a photovoltaic power generation panel (3), and a zipper gasket (4) having pinching and fixing portions (4ac) in both sides for holding the protruding portions (1b) and the fixing portions (2a) together, panel groves (4ab) in both sides for holding the photovoltaic power generation panel (3) and a zipper fitting groove (4aa) and a zipper body (4a) in both sides for tightening the panel grooves (4ab) by insertion of the zipper body (4a) into the groove(4aa).

Description

Technical field [0001] The present invention relates to a photovoltaic power generation peripheral structure, which is used to connect photovoltaic power generation panels to peripheral bodies such as roofs and walls of buildings. Background technique [0002] Generally speaking, a photovoltaic power generation system is composed of photovoltaic power generation panels provided with solar cells that convert the energy of sunlight into electrical energy, a junction box that gathers DC wires from multiple photovoltaic power generation panels, and A power regulator that converts the DC power supplied from the junction box into AC power and controls the frequency, voltage, current, phase, output quality, etc. A plurality of photovoltaic power generation panels of a photovoltaic power generation system are usually arranged on a peripheral body such as a roof and a wall of a building, and the photovoltaic power generation panels are connected in series. [0003] As the installation met...

AI Technical Summary

Problems solved by technology

[0007] However, since it is necessary to drill a hole for wiring at least through the peripheral body itself in each roofing material to lead wiring cables for inputting and outputting electric energy converted by solar cells to the outside of the outdoor, when connecting with the peripheral body In the integrally formed photovoltaic power generation panel, there is a defect that the weather resistance performance deteriorates due to rainwater flowing in through the hole for wiring and leakage occurs.

In addition, because the building itself, the peripheral body, etc. vibrate due to the swaying caused by the surrounding environment, wind, etc., deformation occurs in the hole for wiring, so that there is a defect that the weather resistance performance is further deteriorated.
