Backrail and backrail adapter for a frameless multilayer solar module

摘要

A supporting backrail (10) for a frameless multilayer solar module (40) for insertion into a carrier system (50), the solar module (40) having a front side and a rear side (42), each preferably made of glass, between which an energy-generating Layer (74) is embedded; wherein the backrail (10) has an elongated main body (12) whose geometric length (LB) in its longitudinal direction (L) of a geometric length (LS) of the back (42) of the solar module (40) from an outer edge (112) to a opposite outer edge (114) of the solar module (40), between which the main body (12), preferably by means of a bond (80), on the back (42) of the solar module (40) is mounted; wherein the backrail (10) further comprises at least one nose element (28) which adjoins one of the longitudinal ends (30, 32) of the main body (10) in the longitudinal direction (L) and which, when the backrail (10) on the solar module (40) is attached, extends around one of the outer edges (112) of the solar module (40) without contact; and wherein the nose element (28) has a first section (108) extending in the longitudinal direction (L) and a second section (110) connected to the first section (108) and contacting along the one outer edge (112 ) that the second section (110) projects beyond the front side of the solar module (40) in a height direction (H) (ΔH).
