Patent ID: 8820030

Claim:
A method of mounting a holding and fastening device for at least one solar module in a predetermined alignment on a roof surface, the holding and fastening device having two carrier elements that are arranged parallel at a predetermined distance from each other, each of the two carrier elements having a receiving surface for receiving the solar module at a distance above a roof surface, the receiving surface of one of the two carrier elements being arranged at a different distance from the roof surface than the receiving surface of the other carrier element, both receiving surfaces having a lining of elastomeric vibration-damping material; at least two vertical stabilizing elements connecting the carrier elements at the predetermined distance from each other; and fastening means for fastening to the roof surface, the fastening means having at least one flat support section with a support surface for a plane-parallel support on the roof surface, wherein at least one of the carrier elements is provided with connector means for fastening to at least one further carrier element of a further holding and fastening device, the method comprising the steps of: preassembling the two carrier elements and the at least two vertical stabilizing elements with one another to form the holding and fastening device in absence of the solar module to form a preassembled holding and fastening device; placing the preassembled holding and fastening device on the roof surface with the planar support section in a plane-parallel manner; placing a fastening layer over the support section, the fastening layer extending beyond the support section; and creating an adhesive connection between the fastening layer and the roof surface in such a way that the support section of the preassembled holding and fastening device is pressed onto the roof surface and secured thereto by the fastening layer in absence of the solar module while the roof surface remains intact.
