System for butt jointing photovoltaic modules, and roof-covering created with photovoltaic modules joined by means of jointing systems of this type

摘要

In the system for butt jointing a first and at least one second photovoltaic module (1) for creating a roof-covering, each module (1) comprises a panel (2) with photovoltaic cells and a support frame (3) having at least one longitudinal end profile (4) and at least one longitudinal side profile (5), at least one longitudinal common support profile (6) being also provided at least for the longitudinal end profile (4) of the frame (3) of the first module (1), and for the longitudinal end profile (4) of the frame (3) of the second module (1), with the longitudinal end profile (4) in each module (1) having a box-section longitudinal body (7) fixable to the longitudinal side profile (5), a first longitudinal wing (8) delimiting a seat (9) for engaging the panel (2), and at least one second longitudinal wing (10) having an arched longitudinal surface (11) for engaging with the support profile (6), the support profile (6) having a longitudinal base (12) from which extends a first longitudinal support and guide element (13) having an arched longitudinal surface (14) of a shape matching that (11) of the second wing (10) for engaging with the arched surface (11) of the second wing (10) of the end profile (4) of the first module (1), and a second support (15) and guide element longitudinally parallel to the first support and guide element (13), and having a longitudinal surface of arched form (16) matching that (11) of said second wing (10) for engaging with the arched surface (11) of the second wing (10) of the end profile (4) of the second module (1), the arched surface (14, 16) of the first and said second support and guide element (13,15) being positioned on the same side but at a different distance from the base (12).
