NOVELTY - The method involves providing a transparent substrate (1) with an active region (3) for converting solar power. Another transparent substrate (5) is provided. The two substrates are arranged parallel to each other with a predetermined space, where the active region is arranged between the two substrates. An interstice is filled with liquid material. The liquid material is cured such that the active region is encapsulated, where the material is polymer material i.e. polyurethane plastic. Multiple attachment members are provided to attach a thin layer solar module at a sub-construction.    USE - Method for manufacturing a thin layer solar module.    ADVANTAGE - The interstice is filled with liquid material, and the liquid material is cured such that the active region is encapsulated, so that the method enables manufacturing the thin layer solar module without utilizing autoclaves in a simple and easy manner and ensuring continuous-flow process. The material is polymer material i.e. polyurethane plastic, thus improving protecting or stabilizing properties of the thin layer solar module and prolonging service life of the module. The thin layer solar module comprising the encapsulation can comprise multiple layers with different thermal and electrical characteristics, so that the encapsulation unit can ensure simplification of the arrangement of the interfaces and rigidity of the module. The encapsulation unit is enclosed over an edge of the substrate, so that the substrate can be protected against rupture. Multiple attachment members can be integrated for attaching the thin layer solar module at the sub-construction, and/or multiple electrical terminal devices, and/or one or multiple reinforcement elements over the edge of the transparent substrate with the active region into the encapsulation unit, thus avoiding the need for an expensive fastening process such as sticking and a bolting.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a thin layer solar module comprising an encapsulation unit for covering an active region.    DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a thin layer solar module.    Transparent substrates (1, 5)    Active region (3)    Idle surface area of active region (7)
