The spacer comprises a first flat part spanning a first flat part plane together with first flat part outer edges, and a further flat part spanning a further flat part plane together with further flat part outer edges. The first flat part has fixing means and/or the further flat part has further fixing means. The first flat part and the further flat part configured to be mounted on one another such that the first flat part plane is arranged at a fixing angle to the further flat part plane and forms, between the first flat part plane and the further flat part plane, a plug recess located a distance from the first flat part outer edges and the further flat part outer edges. ## Claims ### Claim 1 A kit of parts for a solar module system, comprising a solar module having a positive pole cable with a positive pole plug, and having a negative pole cable with a negative pole plug, a spacer, wherein the spacer has a first flat part, which spans a first flat part plane with first flat part outer edges, and a further flat part, which spans a further flat part plane with further flat part outer edges, wherein the first flat part has a first connecting structure and/or the further flat part has a further connecting structure, the first flat part and the further flat part can be mounted on one another in such a way that the first flat part plane is arranged at a fixing angle to the further flat part plane and a plug recess which is at a distance from the first flat part outer edges and the further flat part outer edges are formed between the first flat part plane and the further flat part plane; and wherein the positive pole plug or the negative pole plug is arranged in the plug recess on the spacer. ### Claim 2 (depends on 1) The kit of parts as claimed in claim 1, wherein the fixing angle is in a range of from 75° to 90°. ### Claim 3 (depends on 2) The kit of parts as claimed in claim 2, wherein the fixing angle is in a range of from 80° to 90°. ### Claim 4 (depends on 3) The kit of parts as claimed in claim 3, wherein the fixing angle is in a range of from 85° to 90°. ### Claim 5 (depends on 1) The kit of parts as claimed in claim 1, wherein the first connecting structure and/or the further connecting structure are designed as mechanical connecting structures. ### Claim 6 (depends on 5) The kit of parts as claimed in claim 5, wherein the first connecting structure of the first flat part is designed as a slot which is designed in such a way that it fits around a section of the further flat part in an assembled state of the spacer, and/or the further connecting structure of the further flat part is designed as a slot which is designed in such a way that it fits around a section of the first flat part in an assembled state of the spacer. ### Claim 7 (depends on 1) The kit of parts as claimed in claim 1, wherein the flat part and the further flat part are of identical design. ### Claim 8 (depends on 1) The kit of parts as claimed in claim 1, wherein the first flat part is of axially symmetrical design in its first flat part plane and/or the further flat part is of axially symmetrical design in its further flat part plane. ### Claim 9 (depends on 1) The kit of parts as claimed in claim 1, further comprising a fastening structure designed to fasten the positive pole plug or the negative pole plug on the spacer in a state in which said fastening structure is fastened on the spacer. ### Claim 10 (depends on 9) The kit of parts as claimed in claim 9, wherein the fastening structure is selected from the group consisting of UV-stable binders, UV-stable clamping means, adhesives, magnetic means and/or mechanically acting touch-and-close fastening means. ### Claim 11 (depends on 9) The kit of parts as claimed in claim 9, wherein the fastening structure is designed as a cable tie. ### Claim 12 (depends on 9) The kit of parts as claimed in claim 9, wherein the first flat part and the fastening structure are of integral design and/or the further flat part and the fastening structure are of integral design. ### Claim 13 (depends on 1) The kit of parts as claimed in claim 1, wherein the first flat part has at least one cutout, which extends in the first flat part plane, and/or the further flat part has at least one further cutout, which extends in the further flat part plane. ### Claim 14 (depends on 1) A method for producing a solar module system, comprising the following steps: providing a plurality of kits of parts as claimed in claim 1, assembling the first flat part with the further flat part using the first connecting structure and/or the further connecting structure to produce an assembled spacer in such a way that the first flat part plane is arranged at a fixing angle to the further flat part plane and forms a plug recess, which is at a distance from the first flat part outer edges and the further flat part outer edges, between the first flat part plane and the further flat part plane, connecting the positive pole plug of one of the solar modules to a further negative pole plug of one of the further solar modules, thus forming a plug connection, arranging the positive pole plug and the further negative pole plug in the plug recess on the assembled spacer, and arranging the assembled spacer on an underlying surface, on which the solar modules also stand. ### Claim 15 (depends on 14) The method as claimed in claim 14, further comprising a step of fastening the positive pole plug and/or wherein the further negative pole plug on the spacer includes fastening the positive pole plug and/or the further negative pole on the spacer with a fastening structure. ### Claim 16 A method of using a spacer in a solar module system having a solar module for holding a plug connection at a predetermined distance from an underlying surface, wherein the spacer has a first flat part, which spans a first flat part plane with first flat part outer edges, and a further flat part, which spans a further flat part plane with further flat part outer edges, and wherein the first flat part and/or the further flat part have/has a first connecting structure, the method comprising: mounting the first flat part and the further flat part on one another in such a way that the first flat part plane is arranged at a fixing angle to the further flat part plane and a plug recess which is at a distance from the first flat part outer edges and the further flat part outer edges is formed between the first flat part plane and the further flat part plane; and arranging a positive pole plug of the solar module or a negative pole plug of the solar module in the plug recess on the assembled spacer. ### Claim 17 (depends on 16) The method as claimed in claim 16, wherein the solar module includes a positive pole cable with the positive pole plug, and a negative pole cable with the negative pole plug, and the solar module system further comprises a further solar module having a further positive pole cable with a further positive pole plug, and having a further negative pole cable with a further negative pole plug, and the spacer is used for arranging the plug connection between the positive pole plug with the further negative pole plug, or between the negative pole plug with the further positive pole plug, on the spacer, the predetermined distance between the plug connection and the underlying surface thus being ensured by the spacer.
