Abstract: A canopy for a compressor or generator installation comprising a chassis (2) with—a base plate (3) comprising a body with a mounting surface bounded by a polygonal peripheral edge (4); and—a mounting frame (5) containing this base plate (3) and going around the peripheral edge (4); whereby the canopy (1) further comprises a number of corner stays (6), whereby each corner stay (6) is provided with a mounting end which is configured to be mounted onto the chassis (2), whereby at each corner of the peripheral edge (4), at least one corner stay (6) is mounted with its mounting end onto the chassis (2), whereby each corner stay (6) in a mounted state extends from the mounting surface of the base plate (3) in a direction essentially perpendicular to the mounting surface and outwards from the body of the base plate (3), and whereby each corner stay (6) in a mounted state has a free end which is opposite to the mounting end of this corner stay (6) and which is not mounted onto the mounting surface; and whereby the ca
