NOVELTY - Operating a stringer (10) comprises entering a new roll (2) with a new continuous solder ribbon strip (13.2); connecting the end (17) of the momentarily employed continuous solder ribbon strip (13.1) to the new continuous solder ribbon strip (13.2) within a connecting station (11); moving the composed continuous solder ribbon strip to a cutting station (14); cutting the composed continuous solder ribbon strip into solder ribbon cut-offs in the cutting station (14); and removing the solder ribbon cut-offs that comprises the connection point.    USE - The method is used for operating a stringer (10), where solar cells are connected in series with each other by means of solder ribbon cut-offs, the solder ribbon cut-offs being cut off a continuous solder ribbon strip (claimed).    ADVANTAGE - The method is a method for operating a stringer by which the exploitation of the continuous solder ribbon strip(s) can be improved; by which an employed continuous solder ribbon strip that runs out can be connected to a new continuous solder ribbon strip time-savingly; and by which an employed continuous solder ribbon strip that runs out can be connected to a new continuous solder ribbon strip during running operation of the stringer.    DETAILED DESCRIPTION - Operating a stringer (10), where solar cells are connected in series with each other by means of solder ribbon cut-offs, the solder ribbon cut-offs being cut off a continuous solder ribbon strip (13), comprises monitoring depletion of the momentarily employed continuous solder ribbon strip (13.1) by means of a monitoring unit (16); detecting by means of the monitoring unit (16) when the end (17) of the momentarily employed continuous solder ribbon strip (13.1) approaches; entering a new roll (2) with a new continuous solder ribbon strip (13.2); connecting the end (17) of the momentarily employed continuous solder ribbon strip (13.1) to the new continuous solder ribbon strip (13.2) within a connecting station (11) thus forming a composed continuous solder ribbon strip with a connection point; moving the composed continuous solder ribbon strip to a cutting station (14); cutting the composed continuous solder ribbon strip into solder ribbon cut-offs in the cutting station (14); and removing the solder ribbon cut-offs that comprises the connection point. An INDEPENDENT CLAIM is a stringer for performing a method above, comprising a feeding station for supplying a continuous solder ribbon strip (13) and a cutting station (14) for cutting the continuous solder ribbon strip (13) into solder ribbon cut-offs; a monitoring unit (16) for monitoring depletion of the momentarily employed continuous solder ribbon strip (13.1), a connecting station (11) for connecting the end (17) of the momentarily employed continuous solder ribbon strip (13.1) to the new continuous solder ribbon strip (13.2) to form a composed continuous solder ribbon strip with a connection point, and removing means (19) for removing a solder ribbon cut-off that comprises the connection point.
