NOVELTY - The device has a male connector (100) arranged on a generating unit (1A) of a photovoltaic panel (1), where the connector has a set of external connection strips (5, 5', 5'') electrically connected to electricity generating cells. Two external connectors (180, 190) comprise electrical connection vanes (181, 191) with the strips connected to polarities of the cells, respectively. A maintaining unit i.e. socket (140), maintains an assembly of connectors and an electrical interconnection strap (160).    USE - Device for external electrical connection of an electrically active cell i.e. electricity generating cell, of an electrically active panel i.e. photovoltaic panel (all claimed), in a building e.g. house. Can also be used for connecting an electrical receiver such as LCD panel, organic electroluminescent panel, and display panel e.g. plasma screen.    ADVANTAGE - The device permits providing a universal unit for external electrical connection of the electricity generating cells of the photovoltaic panel on an external circuit, and avoids hiding of one of surfaces of the panel when the panel is transparent. The device permits satisfying a connector technology on the generating unit of the panel irrespective of the transparent or opaque type of the panel. The device permits satisfying the intervention on the electrical connection of the panels while ensuring safety by international protection rating (IP2X) stakeholders irrespective of the type of the panel based on IEC 529 AND NF EN 60529 standards.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electrically active panel i.e. photovoltaic panel, mounted in a support frame comprising four hollow tower legs.
