Roof-integrated photovoltaic system {Roof Type Building-integrated Photovoltaic System}

The present invention relates to a roof-integrated photovoltaic power generation device, and more particularly, it is possible to select and construct insulators of various thicknesses by easily varying the height while securing a bearing capacity through a support assembly supporting a solar module, and furthermore, the support The wings constituting the assembly are branched at an angle to both sides to enhance seismic performance due to a buffering effect. In addition, when the inclined blades are fastened together, the upper and lower surfaces of the insulator through the restraining plate portion that rises upward or downward by the reaction force It relates to a roof-integrated photovoltaic power generation device that restrains by pressurization to form a more stable coupling structure.

In general, a photovoltaic power generation facility is a power generation method for generating electric power by converting sunlight into direct current electricity, and solar power generation uses a photovoltaic power generation module.

Environmental problems of fossil fuels and technology development for the use of renewable energy are expanding, and as demand for renewable energy increases, demand for solar cells and photovoltaic facilities is increasing.

The solar cell is preferably installed at a point exposed to sunlight for a long time, and is generally installed on the roof of a building.

However, when installed on the roof of a building, there is a problem in that the installation is limited according to the exterior of the building, so that it cannot be used efficiently.

Photovoltaic power generation modules are generally installed on the ground or on the roof of a building, but recently they are installed in the form of a Building Integrated Photovoltaic (BIPV) system integrated with a building.

Recently, natural disasters such as heat waves, severe cold, storms, heavy snowfall, and earthquakes frequently occur due to abnormal weather phenomena, and thus, performance enhancement of roofing materials is required.

In addition, there is a demand for products to improve insulation performance through the application of high insulation materials for building energy saving, thermal bridge blocking, and application of passive materials.

In addition, it causes problems in the safety and performance of buildings such as deterioration and damage of the building envelope due to storms, heavy snow, earthquakes, etc.

In addition, heat insulation performance deteriorates during heat waves and severe cold due to deterioration in thermal bridge blocking performance, resulting in an increase in building energy consumption.

Solar modules tend to operate by arranging more solar cells in series in order to realize high voltage, and the size of the module also tends to increase.

At this time, as the solar cell panel has a large area, sagging occurs due to use environments such as wind pressure, snow load, and self-weight.

When some surfaces of the solar cell panel sag, water or dust accumulates, reducing the efficiency of the solar cell panel and causing damage.

In addition, in the past, there was no seismic function, and there was difficulty in responding to blocking thermal bridges for each thickness of the insulation material, and the upper and lower structures (Z-type) of the connecting member were different, causing buckling to occur, resulting in structurally weak performance. .

Accordingly, in the related art, registration number 10-1681208 of 'building integrated solar power generation roof and its construction method', registration number 10-2277989 number of 'building integrated solar power generation system', and registration number 10-2292567 number of 'thermal bridging device are provided. Although a 'building-integrated photovoltaic power generation system' has been disclosed, the above problems are still not being improved.
