Photovoltaic module assembly for building exterior and its construction method

The present invention relates to a solar module assembly for building exterior and a construction method thereof, and more particularly, by integrally configuring a solar cell module and a plurality of module frames, a plurality of solar module assemblies are continuously installed on the outer wall of a building, roof or structure. It relates to a solar module assembly for building exterior that can be jointly constructed and a construction method thereof.

In general, photovoltaic power generation is a technology that directly produces electricity using solar cells. A solar cell is a semiconductor device that converts light energy into electrical energy using the photoelectric effect, and is composed of two semiconductor thin films each having positive (+) and negative (-) polarities. ) are connected in series/parallel to generate the voltage and current required by the user, and the user can use the power generated by the solar cell.

Unlike other alternative energy utilization technologies, this photovoltaic system has a simple system configuration, so efforts to apply it to the building field have been actively attempted recently, and this is called a Building Integrated Photovoltaic (BIPV).

A BIPV system (Building Integrated Photovoltaic System) is a PV system integrated into a building, and refers to a solar power generation system that uses a building-integrated photovoltaic module as a building exterior material in addition to generating electricity from solar energy and supplying it to consumers.

The most representative is combining existing building materials with solar cells to simultaneously demonstrate building materials and power generation functions. For the BIPV system, research on BIPV modules and building application techniques has been actively conducted for the past 10 years, and currently and in the future, buildings that produce electricity while serving as building materials by integrating PV modules using the roof and elevation of the building It is a technology that is in the limelight as a skin technology. The BIPV system must be planned and constructed in harmony with the building from the design stage. There are various application methods for each building type, and depending on the application area, it can be divided into upper building elements such as roofs, building elevation elements such as walls, and awnings or lighting elements.

In this BIPV system, it is necessary to consider not only the reduction of workability due to the frame structure of the module, but also the effect of installation on the frame structure of the wall. Therefore, when installing PV modules, systems such as ease of construction, shortening of construction period, water leakage prevention, durability, and safety should be planned.

Recently, a technology for maximizing efficiency by installing a BIPV system on an outer wall, single window, curtain wall, or outer wall of a building has been developed. However, there is a problem that causes a lot of inconvenience during the construction of the outer wall of the conventional module frame, increases problems such as safety during application, and affects the safety of the constructor. Watertightness, ease of construction, and shortening of the construction period are very important factors in terms of architecture, but there are various problems in applying BIPV modules in existing construction methods, so technology to apply innovative BIPV modules to wall installation methods is needed. .

The technology of integrating solar cells into buildings is a concept that converts solar cell modules into construction materials and applies them to the exterior walls or roofs of buildings, thereby increasing economic feasibility as well as various added values to more efficiently supply and activate solar cell systems. In other words, in addition to producing electrical energy with solar energy through the BIPV system and supplying it to consumers, it is used as an exterior material for buildings to reduce construction costs and improve the beauty of buildings.

However, in the conventional technology as described above, the filling material (caulk), which is a type of petroleum compound, changes its physical properties to oily substances due to external environments such as ultraviolet rays, solar heat, and acid rain, and flows down like an oil strip on the outer wall of the building, which is not good for appearance. In addition, due to the limit of the durability of caulking, rainwater flows through the gaps, causing problems such as water leakage and condensation, thereby contaminating the corrosion of the frame and interior finishing materials, thereby weakening durability and stability.

In addition, lateral loads acting on buildings or structures due to earthquakes or strong winds can cause damage to module frames or solar cell modules, and as earthquakes with high intensity have recently occurred in Korea, earthquake resistance is required in the field of BIPV systems as well. am.
