NOVELTY - Silicone junction box (1) comprises: a silicone base member (3) comprising a silicone composition for housing an electrical connection; and a cover member (21) in sealing operative contact with the silicone base member.    USE - The silicone junction box is useful as photovoltaic use-type silicone junction box in a photovoltaic panel assembly and photovoltaic system (all claimed).    ADVANTAGE - The silicone junction box: has an outdoor use rating of f2 or better, a flammability rating of 5VA or better, a hot wire ignition rating of less than or equal to 4, a high-current arc ignition rating of less than or equal to 3, a comparative tracking index rating of less than or equal to 2, and a relative thermal index rating of greater than or equal to 90 degrees C, which are measured using Underwriters Laboratories (UL) 1703 and UL 746C (claimed) ; is flexible and exhibits improved resistance to cracking and UV light and water resistance, hence it can be used in abusive environments; utilizes the silicone composition, which exhibits improved storage stability; has a silicone exterior surface that has sufficient adhesion to a silicone adhesive without priming or activating; and protects the electrical connections from the abusive environments such as heat, cold, weather elements, dust, physical impact or vibration.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a photovoltaic panel assembly comprising: a subassembly of electrically connected photovoltaic cells; a photovoltaic use-type silicone junction box comprising the silicone base member and the cover member; and an electrical connector disposed within the silicone junction box and in electrical connection to the subassembly; and    (2) a photovoltaic system comprising: the subassembly of electrically connected photovoltaic cells; the photovoltaic use-type silicone junction box; the electrical connector; and an electric cable extending into the silicone junction box and in sequential electrical connection to the electrical connector and subassembly.    DESCRIPTION OF DRAWING(S) - The figure shows a perspective view of the silicone junction box comprising a printed circuit board.
