Publication number: 20160049537Abstract: It is an object to provide a solar cell module having a uniform configuration, presenting stable output characteristics, and having a size enabling easy wiring in arrangement and a solar cell array presenting stable output characteristics by employment of said solar cell modules. A solar cell module 10 has a solar cell panel 12 having a length of its longer edges of 900 to 1100 mm. The solar cell panel 12 is constituted by a number of unit solar cells 100 connected in series and has an open-circuit voltage of 100 to 180 volts. The unit solar cell 100 is of a strip-like shape with a length of its shorter edges of 7 to 12 mm and arranged in a longer-edge direction of the panel 12 so that its longer edges extend in a shorter-edge direction of the panel 12 and its shorter edges extend in the longer-edge direction of the panel 12.Type: ApplicationFiled: October 29, 2015Publication date: February 18, 2016Inventors: Yasuhiro Ueda, Takeharu Yamawaki, Kensuke Ishida, Takeharu Nakajima, Tadashi Obayashi

Patent number: 6506970Abstract: The invention includes a tile main body, a recess formed in the tile main body for receiving a photovoltaic module having its reverse surface provided with a terminal box, and a terminal-box-receiving recess provided at the bottom of the recess for receiving the terminal box. A cable lead-out section is provided at a portion toward a ridge of a roof. Output lead-out cables connected to the terminal box are led from the lead-out section toward the ridge.Type: GrantFiled: December 5, 2001Date of Patent: January 14, 2003Assignee: Kaneka CorporationInventor: Takeharu Yamawaki

Patent number: 6489552Abstract: A photovoltaic cell module tile that includes a tile body, a recess, a fitting section, and a pressure member. The recess is provided in a top surface of the tile body, which stores a photovoltaic cell module. The fitting section is provided in the recess on an eaves side of the tile body. An eaves-side end portion of the photovoltaic cell module is inserted and fitted in the fitting section. The pressure member is provided on a ridge side of the tile body and presses a ridge-side end portion of the photovoltaic cell module against the tile body.Type: GrantFiled: November 19, 2001Date of Patent: December 3, 2002Assignee: Kaneka CorporationInventors: Takeharu Yamawaki, Teruki Hatsukaiwa, Fumihiro Tanigawa, Isao Yoshida

Publication number: 20020043277Abstract: The invention comprises a tile main body, a recess formed in the tile main body for receiving a photovoltaic module having its reverse surface provided with a terminal box, and a terminal-box-receiving recess provided at the bottom of the recess for receiving the terminal box. A cable lead-out section is provided in a side wall located at the ridge-side of a roof where the tile main body is mounted on the roof. Output lead-out cables connected to the terminal box are led from the lead-out section to the ridge side. This structure prevents rainwater entering the receiving recess from reaching a connection of the terminal box and the cables.Type: ApplicationFiled: December 5, 2001Publication date: April 18, 2002Applicant: KANEKA CORPORATIONInventor: Takeharu Yamawaki

Publication number: 20020036010Abstract: A recess which stores a photovoltaic cell module is provided on the top surface of a tile body arranged on a roof or the like of a house. A fitting section having a groove is formed by undercutting at least one side of the recess. An end portion of the photovoltaic cell module is inserted and fitted into the fitting section. The photovoltaic cell module is therefore detachably fixed in the recess of the tile body.Type: ApplicationFiled: November 19, 2001Publication date: March 28, 2002Applicant: KENEKA CORPORATIONInventors: Takeharu Yamawaki, Teruki Hatsukaiwa, Fumihiro Tanigawa, Isao Yoshida

Patent number: 6268559Abstract: A wiring apparatus comprises a trunk cable, branch junctions, and branch cables diverging individually from the branch junctions. A plurality of photovoltaic modules, which are arranged side by side on a roof of a building or the like, or module units, composed of the modules, serve as generating sections. The respective outputs of the generating sections are lead into the building by means of a trunk conductor of the trunk cable. Each branch cable includes a branch conductor that is connected to the trunk conductor of the trunk cable. Each branch cable of the wiring apparatus is connected to a connector for use as an output terminal of the module units by means of a connector attached to the distal end portion thereof. The module units are connected in parallel with one another by means of the wiring apparatuses, and their respective outputs are supplied to loads in the building by means of a pair of lead-in wires.Type: GrantFiled: October 6, 1999Date of Patent: July 31, 2001Assignee: Kaneka CorporationInventor: Takeharu Yamawaki
