Description

Elevation finishing material type Building Integrated Photovoltaic (BIPV) System}

This design is a building-integrated photovoltaic power generation system and concerns the application of a vertical facade finishing material such as the exterior wall of a building. More specifically, when placing solar modules on the exterior wall of a building as a construction finishing material, water leakage due to rainwater, etc. is prevented. It is about a building-integrated solar power generation device that functions as a structural exterior wall, has natural ventilation to reduce the temperature rise of solar modules, and is a detachable facade finishing material.

Solar power generation generates electricity by irradiating light energy to solar cells (modules) made of semiconductors and converting the light energy into direct current electricity. It uses unlimited and pollution-free solar energy, so there are no fuel costs and no air pollution. It generates little waste, has no mechanical vibration and noise, has a long lifespan of at least 25 years, and is easy to maintain.

In general, a solar power generation system includes a solar module that converts light energy into direct current electrical energy, an inverter that converts direct current power into alternating current power, and a connection that transmits the direct current power generated by the solar module to the inverter. AC power converted by the inverter is sent to the power grid system through a separate AC distribution board and supplied to the premises or customers for use.

Since the amount of electrical energy generated from a unit solar cell is very small, several solar cell groups are usually manufactured as modules. In addition, an array is formed with multiple solar modules in series and these groups are again connected in parallel. By uniting, we will secure the necessary power.

Installation of modules, which are key materials for solar power generation, an eco-friendly new renewable energy, requires a certain size of structure and space, and generally, the required area of a module to produce 1KW of power requires a space of at least 4 square meters. In urban areas, it is not easy to secure space, so there are increasing cases of installing them on the exterior walls of buildings, windows, and roofs, and as an integrated building exterior material.

These Building Integrated Photovoltaic (BIPV) devices do not interfere with the exterior of the building and are used as a finishing material for buildings, so they can reduce construction costs to some extent, but they also have problems with water leakage and dust accumulation due to weather conditions. , there is a task of solving the problem of combination of solar module installation as building structure and exterior material, and economic problems.

Building Integrated Photovoltaic (BIPV) is a building-integrated photovoltaic device (BIPV) that solves these problems by installing insulation on the exterior wall that increases the effect of blocking outside air temperature, and attaching a steel Z-bar to secure the solar module while fixing the insulation to the wall. After fixing it vertically, specially manufactured module supports are installed horizontally on the Z-bar at intervals of one module height, and solar modules (PV) are inserted into the module supports and fixed with module fixing clips at regular intervals.

At this time, rubber packing with anti-vibration and waterproof functions is inserted between the module supports at the top and bottom of the module, and between the modules placed on the left and right of the module, the space between the vertical modules is filled with a sealant that has a waterproof effect and has shrinkage properties to prevent vibration. It is fixed, and the exterior wall other than the module is a product with a louver-type air inlet that is difficult to infiltrate by rainwater. It is constructed at the same height as the module finish surface and is completed as an integrated exterior wall of the solar module. This is a solar power generation device that is integrated with the exterior wall of the solar module, providing architectural structural technology. Technologies such as construction budget reduction technology, waterproofing problem, wind vibration treatment, and module generated heat treatment are applied.

In this way, by installing a building integrated photovoltaic (BIPV) device as a façade finish, the architectural role of the exterior wall and solar power generation, an endless eco-friendly new renewable energy, are simultaneously implemented, while providing architectural waterproofing, aesthetic treatment, and expensive reinforcement. Certified PV solar modules are cheaper than glass BIPV modules, and can achieve economic benefits by reducing construction costs using exterior wall materials and reducing the cost of setting up a separate solar module installation site by installing the modules in the exterior wall space.

This design solves architectural engineering structural problems, insulation treatment, vibration treatment due to wind, rainwater treatment problems, dust accumulation due to weather conditions, and modules by harmoniously combining solar modules when integrated and installed with the exterior wall or facade finishing materials as described above. We aim to provide a building-integrated photovoltaic power generation device designed as a façade finishing material to solve the problems of natural ventilation required due to generated heat treatment and the possibility of maintenance in case of breakdown.

In order to solve the above problems, this design is a Building Integrated Photovoltaic (BIPV) device installed on the exterior wall or facade finishing material.
