Corrugated Roof Sheet and Photovoltaic Assembly Comprising the Same

Abstract

A corrugated roof sheet has a bottom, a first-side roof sheet edge portion, a second-side roof sheet edge portion, a retaining cap and a protruding portion. The first-side roof sheet edge portion has a height H 1 from the bottom. The retaining cap covers the first-side roof sheet edge portion and has a lower fringe. The lower fringe has a height h 2 from the bottom. The protruding portion is between the first-side roof sheet edge portion and the second-side roof sheet edge portion and has a height h 3 from the bottom. The height h 2 is greater than the height h 3.
