Device for external electrical connection of the electrically live cells of an electrically live panel, such as the electricity generating cells of a photovoltaic panel

Abstract

Device for the external electrical connection of a photovoltaic panel (1), comprising: a male connector (100) placed on the edge of the photovoltaic panel (1), comprising a plurality of external connection blades (5, 5', 5'') electrically connected to the electricity-generating cells; an electrical interconnection strip (160) for interconnecting the external blades, which comprises electrical junction means (165) for joining to the external connection blades, and electrical circuits suitable for interconnecting the electricity-generating cells; a first external connector (180) comprising an electrical junction means (181) for joining to a first external connection blade; a second external connector (190) comprising an electrical junction means (191) for joining to a second external connection blade; and a means (140) for holding together the assembly comprising the male connector (100), the interconnection strip (160), the first external connector (180) and the second external connector (190).

Description

technical field [0001] The invention relates to a device for the external electrical connection of a power generating unit of a photovoltaic panel. Background technique [0002] In order to provide a building such as a house with a generator using solar energy, an assembly of panels consisting of a plurality of photovoltaic cells is provided, for example, on the roof of said building. The panels generally consist of a stack of different layers of glass, silicon, conductors and polymers. Each side of the typically square silicon unit can measure up to 200mm. The units that make up the generator are assembled in series and then bonded between two sheets of glass or between a sheet of glass and layers of different polymers. As an example, a module with a nominal voltage of 12V typically consists of 36 (2×18) single or polycrystalline units placed in series. The 36-unit assembly was then assembled in parallel. In the case of a 24V module, 72 silicon cells are thus used. [...

AI Technical Summary

Problems solved by technology

[0005] When the photovoltaic panels are transparent, the cable harness is particularly unsightly, which is a disadvantage especially when the panel is intended to be positioned as a surface of a building

This clear panel can be used as a decorative device, however the presence of cable harnesses at the rear that are visible due to the transparent nature of the assembly makes this panel unsuitable for this use
