TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Method: The method (M1) further involves finishing attachment of the solar module assembly while a perimeter of the solar module assembly is fully exposed; curing the adhesive while a perimeter of the solar module assembly is fully exposed where at least one discrete strip of adhesive does not contact the front surface of the solar module assembly. The method (M1) involves providing a roll of a fully assembled thin film solar module, where the thin film solar module includes a front surface and a back surface; applying at least one discrete strip of adhesive to a top surface of the roof; placing the back surface of a first end of the roll of the thin film solar module on top of the at least one discrete strip of adhesive; unrolling the roll of the thin film solar module onto the at least one discrete strip of adhesive; and pressing the back surface of the thin film solar module into the at least one discrete strip of adhesive. The method (M1) involves supplying a fully assembled solar module where the solar module includes a front surface and a back surface; providing a double sided pressure sensitive adhesive tape with a tape surface and a second tape surface having a release liner; applying the first tape surface of the adhesive tape to the roof while the release liner is still on the second tape surface of the adhesive tape; removing the second release liner from the second tape surface of the adhesive tape while the adhesive tape is on the roof; placing the back surface of the solar module on top of the first surface of the adhesive tape such that the front surface of the solar module faces away from the roof; and pressing the back surface of the solar module into the at least one discrete strip of adhesive. In the method (M1), applying at least one discrete strip of adhesive includes applying at least one continuous bead of adhesive using an applicator. Applying at least one continuous bead of adhesive using an applicator involves applying several parallel continuous beads of adhesive using several applicator tips of a multi-bead applicator having a pump that mixes two separate components to create the adhesive. The distance between several parallel continuous beads is preselected to fully adhere the solar module assembly to the substrate. The distance between several parallel continuous beads is preselected to partially adhere the solar module assembly to the substrate with an adhesive to empty space ratio preselected based on expected environmental loads on the solar module assembly. Applying at least one discrete strip of adhesive involves unrolling a self-wound adhesive tape onto the substrate, and removing a release liner to expose a surface on which the solar module will be placed. Applying at least one discrete strip of adhesive involves applying a double sided pressure sensitive adhesive tape after removing a first release liner from the adhesive tape, where placing the back surface of the solar module on top of the at least one discrete strip of adhesive involves placing the back surface of the solar module on top of the double sided pressure sensitive adhesive tape after removing a second release liner from the adhesive tape. The double sided pressure sensitive adhesive tape comprises at least one of one of polyurethane, ethylene-butylene- styrene, polyisobutene, polyisoprene, polybutenes,) styrene-butadiene-styrene (SBS), styrene-ethylene-butadiene-styrene (SEBS), styrene-isoprene-styrene (SIS), and acrylics comprising blends of methyl, ethyl, butyl, and 2-ethylthexyl acrylates and methyl, ethyl, butyl, and 2-ethylhexyl methacrylates. The solar module is a thin film solar module and placing the back surface of the solar module on top of the at least one discrete strip of adhesive includes unrolling a roll of the thin film solar module so that a backsheet of the thin film solar module contacts the at least one discrete strip of adhesive. Applying at least one discrete strip of adhesive involves applying at least one discrete strip of adhesive to the roof on a perimeter of an expected location of the solar module on the roof. Applying at least one discrete strip of adhesive involves applying at least one discrete strip of adhesive in an amount that is preselected based on expected environmental loads on the solar module assembly. The adhesive is one of a hot mop asphalt of type 1-4 with polymeric additives, a hot mop asphalt of type 1-4 without polymeric additives, pine tar pitch with polymeric additives, pine tar pitch without polymeric additives, ethylene vinyl acetate (EVA) copolymers compatible with paraffin, 1k polyurethane, 1k silicone epoxy, 2k polyurethane, styrene-isoprene-styrene (SIS) copolymers, styrene-butadiene-styrene (SBS) copolymers, ethylene ethyl acrylate copolymers (EEA), polyurethane reactive (PUR), butyl or halo-butyl rubbers, acrylic, ethylene propylene rubber (EPR), ethylene propylene diene terpolymer rubber (EPDM), styrene/butadiene rubbers (SBR), and styrene-ethylene-butene-styrene copolymers (SEBS). The solar module assembly includes a thin film solar module adhered to a fleece backed roofing membrane. Preferred Components: The solar module is a thin film solar module. The top side of the roofing membrane is made from one of ethylene propylene diene terpolymer and thermoplastic olefin. The fleece layer is a non- woven polyester fleece type layer. The ratio of adhesive to empty space in the adhesive layer is preselected based on a predetermined wind lift force. The adhesive layer includes a hot melt adhesive. Preferred Assembly: In the assembly (G1), the period of time of curing for the second adhesive layer is longer than a period of time of curing for the urethane adhesive layer at a single point in time. The urethane adhesive layer is a two part adhesive composition comprising a resin part and an isocyanate part. EXAMPLE - No suitable example given.
