Patent number: 9640486Abstract: The invention relates to a method for marking wafers, in particular wafers for solar cell production: The method comprises the steps of manufacturing a position line (21a, 21b, 21c) on a peripheral surface of a silicon ingot or column, the ingot or column extending in an axial direction and having a longitudinal axis in the axial direction, wherein the position line extends in the axial direction along substantially the whole ingot or column and is inclined with respect to the longitudinal axis. By this position line it is possible to determine the position of a wafer cut from the ingot or column within the ingot or column, respectively. Further, an individual identification pattern (20a, 20b, 20c) of lines on the peripheral surface of the silicon ingot or column is manufactured, the individual identification pattern of lines extending in axial direction over substantially the whole ingot or column and providing an individual coding which allows to identify the silicon ingot or column.Type: GrantFiled: June 13, 2007Date of Patent: May 2, 2017Assignee: Conergy AGInventors: Andre Richter, Marcel Krenzin, Jens Moecke

Patent number: 7849849Abstract: The invention relates to a frame assembly for mounting solar modules (1), said frame assembly comprising at least two flat frames which are arranged at a distance, preferably forming a triangle respectively with the frame sides (2, 3, 4) thereof, respectively one frame side (4) being inclined in relation to the surface of the ground or the roof (5). Carrier profiled parts (6, 7) which can be respectively displaced and fixed and are used to support and fix a solar module (1) are respectively arranged on two adjacent frames on the inclined side (4) of the frame. The carrier profiled parts (6, 7) are used to ensure the connection to the adjacently arranged frame sides (2, 3) in such a way that they can be displaced and fixed in relation to each other. The frame sides (2, 3) are also connected in such a way that they can be displaced and fixed in relation to each other and/or comprise at least one length adjustment device.Type: GrantFiled: February 28, 2005Date of Patent: December 14, 2010Assignee: Conergy AGInventor: Gido Genschorek

Publication number: 20090316448Abstract: The invention relates to a power inverter circuit for coupling a power station to a power supply system. The invention addresses the problem to reduce the risk of damages to components of the power station and the power supply system in the course of coupling action by providing a power inverter circuit for adjusting symmetry of the AC voltage before coupling the inverter output to a load, comprising: first switching means for selectively connecting a positive voltage to the inverter circuit output, second switching means for selectively connecting a negative voltage to the inverter output, and ohmic resistance means coupled in parallel to the inverter output, a controller for selectively switching the first and second switching means with a switching frequency to produce an AC voltage from the positive and negative voltage, wherein the controller is adapted to alter the duty ratio of the switching frequency to adjust the symmetry of the AC voltage produced by the inverter.Type: ApplicationFiled: September 25, 2006Publication date: December 24, 2009Applicant: Conergy AGInventors: Peter Knaup, Karl Koch, Thomas Lenz

Patent number: 7634875Abstract: The invention relates to a mounting system consisting of aluminum profiles (1, 11) in which threaded sliding blocks (14) inserted in the profiles are used, in particular, for fastening to solar modules and roof supports. The mounting system comprises at least two spaced apart profiled mounting rails (1) respectively with a support (2) limiting the profile height (7) and a connection (3) below the support (2) for the roof mounting. Threaded sliding blocks (14) are inserted in a form-fitting manner in each profiled mounting rail (1) for fastening the connection with the solar modules and the roof mounts. The profiled mounting rail has additional connecting profiles (4, 5, 6), arranged on the side or on the side and bottom, for engagement with complementary connecting profiles (8, 9, 10) of a profiled connecting rail (11). The profiled mounting rail (1) can be extended by sliding shaped pieces (13) with the profile of the profiled mounting rail (1) onto the profiled connecting rail (11).Type: GrantFiled: January 10, 2006Date of Patent: December 22, 2009Assignee: Conergy AGInventor: Gido Genschorek

Publication number: 20090195293Abstract: The invention relates to a power circuit with a emitter-switched bipolar transistor (ESBT) (T2) and a MOS transistor (T3) connected downstream of the bipolar transistor. The bipolar transistor (T2) is controlled by a Mosfet transistor (T1). A zener diode (D1) which is disposed between the exit of the MOS transistor (T3) and the base of the bipolar transistor (T2) transmits the return current of the base collector diode of the bipolar transistor (T2) to the foot point of the ESBT (T2). Furthermore, a voltage source (U) is inserted between the collector of the bipolar transistor (T2) and the drain of the Mosfet transistor (T1).Type: ApplicationFiled: December 28, 2006Publication date: August 6, 2009Applicant: CONERGY AGInventor: Hans Oppermann
