Abstract: The invention relates to a solar module and a method for manufacturing a solar module, wherein the solar module comprises at least one solar cell; at least two connection elements (3) for establishing an electrical connection to the at least one solar cell; a bypass component (4) which is connected with the connection elements (3) and a connection box (2), in which the bypass component (4) is provided, wherein the connection box (2) comprises a potting material (6) which covers at least partially the bypass component (4). According to the invention the connection box (2) comprises at least one connection area (7, 7a, 7b) which is free of potting material (6), wherein a bypass component (40) and/or another electronic component is connectable with the connection elements (3) using the connection area (7, 7a, 7b). The invention also relates to a method for repairing and/or retrofitting a solar module.

Abstract: The present invention relates to a solar module (1) comprising at least two solar cells (3, 5), wherein each of the solar cells (3, 5) comprises an upper end (21), a lower end (23) which is situated opposite the upper end (21), two opposite side ends (25, 27) and at least one busbar (11, 13) which extends from the first side end (25) to the opposite second side end (27) of the solar cell (3, 5), wherein at least one finger (7, 9) of the solar cell (3, 5) makes electrical contact with the busbar (11, 13), wherein at least one first busbar (11) of at least one first solar cell (3) is arranged at a first side end (25), which is situated opposite a second side end (27) of at least one second solar cell (5) which is arranged or can be arranged next to the first solar cell, at a first distance from the upper end (21) of the at least one first solar cell (3), and at least one second busbar (13) of the at least one second solar cell (5) is arranged at the second side end (27) at a second distance from the upper end (

Abstract: A solar cell module (100) comprises a first terminal (101) and a second terminal (102), a plurality of solar cells (110) and a switch (120). The solar cells (110) can be electrically connected to one another between the first terminal (101) and the second terminal (102) in order to generate a voltage between the first terminal (101) and the second terminal (102) in normal operation. The switch (120) electrically connects the first terminal (101) and the second terminal (102) to one another in a default setting or isolates the plurality of solar cells (110) from the first or from the second terminal (101, 102) and can be controlled in such a way that, when a valid control signal is present, the first terminal (101) is electrically isolated from the second terminal (102) or the plurality of solar cells (110) are connected to the first and the second terminal (101, 102).
