Photovoltaic windows

Abstract

The present utility model relates to a connector for photovoltaic windows which is designed to transmit the electrical energy generated by a photovoltaic glass sheet installed in a window pane to the frame, thereby allowing it to be integrated into the electrical grid of the building. The connector consists of flexible conductors embedded in the window joint, which is an electrical contact system between the pane and the frame, having an insulating sleeve. The main advantages include its ease of installation, durability, energy efficiency and aesthetic design, ensuring discrete integration without affecting the functionality of the window. The invention can be used for residential, commercial and industrial buildings seeking to efficiently harness solar energy.

Description

[0001] Title of the invention:

[0002] Photovoltaic Windows

[0003] Description.

[0004] Field of Invention:

[0005] The present invention relates to the sustainable construction sector, and more specifically, to the development of movable opening windows that integrate photovoltaic glass for the generation of solar energy, improving the energy efficiency of buildings.

[0006] Background of the technique

[0007] The use of photovoltaic glass in architecture has increased due to the need to reduce energy consumption. This type of glass is commonly integrated into facades, skylights, or curtain walls, but its implementation in functional windows presents technical challenges related to the sash's mobility and the continuity of the electrical circuit. Currently, there are no widely accepted solutions that allow the incorporation of photovoltaic glass into casement, tilt-and-turn, or sliding windows that simultaneously integrate a secure and automated electrical connection system.

[0008] Object of the invention

[0009] The invention relates to a photovoltaic window that allows it to be opened in operable, hinged or sliding modes, incorporating amorphous silicon glass with different levels of transparency (10%, 20%, 30%) and an integrated electrical connection system, composed of connectors housed in the frame and the sash, which allows the energy generated to be fed into the grid or used in the building.

[0010] Detailed description of the invention

[0011] The invention comprises:

[0012] Yo o A frame (2) and a movable leaf (1) that allows for operable, folding or sliding configurations.

[0013] 2 o A photovoltaic glass (1 A) of amorphous silicon mounted on the sheet, with selectable transparency.

[0014] 3 oAn electrical system consisting of two single-pole connectors (3), one on the leaf and the other on the frame, which establish electrical contact when the window is closed, allowing the conduction of the generated energy to cables (9 and 10) and from there to the network or the electrical system of the building.

[0015] 4 o The connector includes:

[0016] • Metal base (4) for fixing to the frame with screws (hole 7).

[0017] • Insulating jacket (5), preferably made of nylon.

[0018] • Metal clamp-type clip (6), which receives the conductor bolt (8) and connects it to the wiring.

[0019] • Cable (9) from the photovoltaic glass and cable (10) to the grid. Advantages of the Invention:

[0020] • Generation of clean and sustainable energy by harnessing solar radiation.

[0021] • Energy savings in buildings by reducing dependence on conventional energy sources.

[0022] • Maintenance of natural lighting thanks to the different transparency options of photovoltaic glass.

[0023] • Versatility in its installation due to its design with multiple opening systems.

[0024] • Efficient integration of the electrical system through connectors located in the window structure.

[0027] Figure 2: Sectional detail of the single-pole connector, with component numbering and arrangement in the frame.

[0028] Best way to carry out the invention:

[0029] Referring to figure 1, a window sash 1, with a window frame 2, a photovoltaic glass 1 A with cables 2 A for energy injection, and a single-pole connector 3.

[0030] Referring to Figure 2, the connector for fixing to the window frame has a metal base 4, secured by screws in hole 7, and is made of steel. A perimeter sheath of electrically insulating material 5, made of nylon or similar, is also included. A metal clamp-type clip 6, made of aluminum / copper, transmits energy via cable 10 to the grid. This clip 6 secures and transmits energy to the bolt 8, also made of aluminum / copper, which receives energy from the photovoltaic glass via cable 9. The bolt's mounting base is covered by a nylon sheath for insulation from the sash.
