Solar photovoltaic wall Façade

Abstract

The solar photovoltaic wall Façades project involves a new type of wall that can generate electricity.

Solar photovoltaic wall facades are a project to integrate solar cell modules with buildings. The wall façades are composed of a square frame formed by vertical and horizontal frames. The solar cell modules are combined in the square frame. The bottom surface of the solar cell modules has a colored bottom layer, and the back of the photovoltaic facade also has a heat insulation layer. The bottom of wall facades are made of porcelain, natural marble, artificial marble, iron angle steel, stainless steel, colored aluminum profiles and aluminum-plastic panels. Multiple wall tiles are installed on the building facade wall through dry hanging steel structures. Multiple wall bricks are connected to the main conductor, which enters the room through the wall hole to connect to the inverter and work in the city power grid, or connect to batteries, charge and discharge protectors, inverters to power electrical appliances, or combine with solar electronic controllers to directly power electrical appliances. Since it can give photovoltaic panels a different appearance like marble or granite, Solar photovoltaic wall facades realize the integration of solar cell modules with buildings. The use of this Solar photovoltaic façades can keep the traditional architectural style unchanged, beautiful, simple and generous.

Solar photovoltaic wall facades are very important building materials for energy conservation and environmental protection in the future. It will play an important role in controlling the greenhouse effect of the earth and saving earth resources for human beings, and it will produce huge social and economic benefits.

Technical Field

The product discloses a solar photovoltaic wall facade, which relates to a new type of wall surface and can realize the integration of solar cell components and buildings.

Technical Background

At present, solar cell modules are mainly installed on the roofs of buildings for power generation. There are great limitations to installing solar cell modules on the roofs for power generation, because the use area is small and the power generation is limited. Although there are solar glass curtain wall power generation devices installed on the exterior walls of buildings, the glass curtain wall cannot retain the traditional architectural style. Installing glass curtain walls is not only costly, but also leads to poor ventilation, air permeability and light transmission functions of the building, affecting the health of the human body indoors. Some buildings are not suitable for installing solar glass curtain wall power generation at all. In addition, in order to save the manufacturing cost of the wall tiles and save earth resources, a solar photovoltaic wall tiles structure with less materials is designed.

Product Structure

The solar photovoltaic wall facade combines a solar cell module with a special building wall tile to form a new type of solar cell module for power generation and decoration of the exterior wall of a building. The solar cell module is embedded in a square frame, a junction box, a battery conductor, a press seam, a patterned bottom layer bonded to the bottom surface of the solar cell module, and a heat insulation layer bonded to the back of the photovoltaic wall tile.

The bottom layer of the solar cell assembly is made into a pattern layer that is the same as or similar to the surface of the vertical frame and the horizontal frame. The pattern layer of the bottom layer of the solar cell assembly can be seen from the front of the wall tile, to achieve the same pattern as the surface of the square frame.

The above-mentioned solar cell modules are made of monocrystalline silicon, polycrystalline silicon, amorphous silicon thin film solar cells, few-crystalline silicon solar cells, etc.

The heat-insulating layer or the heat-insulating layer is combined with the back of the wall tile or is separately attached to the wall surface of the dry-hanging steel structure area where the photovoltaic wall tile is to be installed. In summer, it can prevent solar heat from entering the room through the wall, and in winter, it can prevent indoor heat from being conducted outdoors through the wall, thereby achieving energy savings.

Working principle

A plurality of solar photovoltaic wall facades are mounted on the outer wall of a building by a dry hanging steel structure to form a large area of solar photovoltaic components to absorb solar energy for power generation; each solar cell conductor is connected to a main conductor through a branch conductor according to the power consumption requirements of the user; each connecting conductor is respectively installed in a wire tube; the wire tube is installed behind the photovoltaic wall tiles between the dry hanging steel structures; the main conductor enters the room through a wall hole and is connected to the main power grid through a grid-connected inverter, or connected to a storage battery, a charge and discharge protector, an inverter device to supply power to electrical appliances, or combined with a solar electronic controller to supply power to electrical appliances directly.
