Device for fixing a support structure for at least one solar panel, in particular a support rail of a support structure for at least one solar panel, to a corrugated roof comprising at least one corrugated roof plate, said device comprising: - at least one base element comprising at least one aperture for receiving at least part of at least one fastening element, in particular a fastening screw, for fixing the device onto a corrugated roof; - at least one, at least partially resilient, first leg which is connected to the base element; - at least one, at least partially resilient, second leg which is connected to the base element, wherein the at least one second leg substantially opposes the at least one first leg, and - at least one top structure connected to the base element, wherein the top structure extends from the base element in upward direction, the top structure being configured for coupling with a support structure for at least one solar panel, in particular a support rail of a support structure for at least one solar panel, wherein the base element, the at least one first leg and the at least one second leg together define a receiving space for receiving at least part of a crest of at least one corrugated roof plate, wherein the first leg and the second leg are each configured to engage opposing valley regions of the corrugated roof plate extending from said crest of the corrugated roof plate, characterized in that the at least one first leg and the at least one second leg diverge away from each other, such that fastening of the device onto said corrugated roof by means of said fastening element, in particular said fastening screw, will cause deformation of both the at least one first leg and the at least one second leg leading to a biased coaction between each leg (4, 5) and a supporting valley region of the corrugated roof plate. - at least one base element comprising at least one aperture for receiving at least part of at least one fastening element, in particular a fastening screw, for fixing the device onto a corrugated roof; - at least one, at least partially resilient, first leg which is connected to the base element; - at least one, at least partially resilient, second leg which is connected to the base element, wherein the at least one second leg substantially opposes the at least one first leg, and - at least one top structure connected to the base element, wherein the top structure extends from the base element in upward direction, the top structure being configured for coupling with a support structure for at least one solar panel, in particular a support rail of a support structure for at least one solar panel, wherein the base element, the at least one first leg and the at least one second leg together define a receiving space for receiving at least part of a crest of at least one corrugated roof plate, wherein the first leg and the second leg are each configured to engage opposing valley regions of the corrugated roof plate extending from said crest of the corrugated roof plate, characterized in that the at least one first leg and the at least one second leg diverge away from each other, such that fastening of the device onto said corrugated roof by means of said fastening element, in particular said fastening screw, will cause deformation of both the at least one first leg and the at least one second leg leading to a biased coaction between each leg (4, 5) and a supporting valley region of the corrugated roof plate. wherein the base element, the at least one first leg and the at least one second leg together define a receiving space for receiving at least part of a crest of at least one corrugated roof plate, wherein the first leg and the second leg are each configured to engage opposing valley regions of the corrugated roof plate extending from said crest of the corrugated roof plate, characterized in that the at least one first leg and the at least one second leg diverge away from each other, such that fastening of the device onto said corrugated roof by means of said fastening element, in particular said fastening screw, will cause deformation of both the at least one first leg and the at least one second leg leading to a biased coaction between each leg (4, 5) and a supporting valley region of the corrugated roof plate.
