  • Patent number: 9537034
    Abstract: The invention is to facilitate the attachment of an installation system in the production of a solar module. This is achieved via a process which comprises the following steps: a) mutual superposition of the layers that the structure of the solar module requires, where at least one heat-activatable double-sided adhesive tape is placed on the external side of the reverse-side layer and at least one retention plate is placed on said adhesive tape; b) mutual lamination of the layers mutually superposed in step a), at least with exposure to heat.
