NOVELTY - The device has a support (40) i.e. metal blank, integrated to a supporting structure (30). The support comprises a locking unit i.e. tab (48), that locks the support with respect to an elongated reinforcing section (20) of a solar energy capture module (10) i.e. frameless photovoltaic module. The locking unit is activated by application of unidirectional push force (F1) from the solar energy capture module towards the supporting structure. The reinforcing section is displaced interiorly with respect to peripheral edges of the solar energy capture module.    USE - Device for attaching a solar energy capture module i.e. frameless photovoltaic solar module that is in the form of laminated glazing, to a supporting structure e.g. roof or facade of a building or supporting structure in open field (all claimed).    ADVANTAGE - The reinforcing section is displaced interiorly with respect to the peripheral edges of the capture module so as to reinforce the structure of the capture module and improve the mechanical resistance of the capture module, thus eliminating the need for having a frame around the periphery of the module for fixing the module on the supporting structure, and hence exposing the entire active surface of the module to solar radiation for ensuring optimal efficiency of the module. The configuration of the support guarantees optimal positioning of the capture module with respect to the supporting structure. The device is configured such that elastic action of the locking unit maintains a detent unit in an active state, thus assuring attachment of the capture module on the supporting structure in a rapid, reliable and robust manner, without embrittlement of the structure of the capture module. The device is configured such that unlocking orifices permit individual disassembling of the capture module from the supporting structure, in case of failure of the capture module.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for mounting a solar energy capture module on a structure e.g. roof, facade or supporting structure in open field.
