Description

The invention relates to a flat roof on a building according to the preamble of claim 1 and to a use of one or more photovoltaic modules for fall protection according to claim 15. Generally, a flat roof may cover a building. A flat roof may have an inclination of up to 10 degrees with respect to a surface normal of a wall of the building. Alternatively, a flat roof may have an inclination of up to 10 degrees with respect to the vertical direction. EP3564599A1 discloses a flat roof with an end wall at the edge of the building and inclined inner and outer solar converters. It may be necessary for a person to access the flat roof of a building, for example for working on the flat roof. In this case, a fall protection at the edges of the flat roof may be necessary according to the standard SN EN 13374. The fall protection may have three parts, in particular three rails, such as a handrail, a central rail and a foot rail. The fall protection may have posts, wherein the distance between two posts may have to be smaller than 250 centimeters. The present invention is directed to the problem of providing flat roof having fall protection in an efficient manner. The objective technical problem is solved by a flat roof according to claim 1 or by using one or more photovoltaic modules according to claim 15. According to the first aspect of the invention, a flat roof on a building comprises a support structure extending along a roof panel, a first mounting structure connected to the support structure in a central area of the flat roof, one or more photovoltaic modules mounted on the first mounting structure, and a fall protection structure connected to the support structure in a peripheral area of the flat roof. The fall protection structure is in a distance to the one or more photovoltaic modules mounted on the first mounting structure. The flat roof may generally have a width of at least 5 meters and/or a length of at least 5 meters, preferably a width of at least 10 meters and a length of at least 5 meters. The flat roof may have a static layer, in particular comprising or being entirely made of metal, concrete or wood. The flat roof may have a roof skin covering the static layer. The roof skin may comprise roof panels, in particular comprising or consisting of galvanized steel, zinc, copper, aluminum, lead or stainless steel. Additionally or alternatively, the roof skin may comprise or may be entirely made of concrete, sheet metal, roofing felt, roofing film, acrylic glass or other transparent materials, bulk material or organic material such as plants, in particular wood. The flat roof, in particular a surface of the flat roof such as the roof skin, may extend at least locally or entirely in a plane, in particular a horizontal plane or in a horizontal direction. The vertical direction may be at an angle of up to 90 degrees, in particular at an angle between 80 degrees and 90 degrees, to the surface plane of the flat roof. The vertical direction may be at an angle of maximally 10 degrees, in particular parallel, to an outer wall of the building. The vertical direction may be at an angle of up to 10 degrees to the surface normal of at least a portion of the surface of the flat roof. The distance between the fall protection structure and the one or more photovoltaic modules mounted on the first mounting structure may be at least 50 centimeters, in particular at least 100 centimeters, in particular at least 150 centimeters. The fall protection structure may be entirely arranged on the flat roof. In particular, the fall protection structure is not directly connected with a wall of the building or with a border element. The one or more photovoltaic modules mounted on the first mounting structure may be arranged at an angle between 0 degrees and 10 degrees with respect to the vertical direction. The size of the peripheral area may depend on the flat roof, in particular the size and/or geometry of the flat roof. The peripheral area of the flat roof may comprise the outer 20 percent, in particular the outer 15 percent, in particular the outer 10 percent, of the width and/or of the length of the flat roof. Alternatively, the peripheral area may extend at least 1 meter, in particular at least 2 meters, in particular at least 3 meters from the nearest edge of the flat roof. The peripheral area of the flat roof may at least partially enclose the central area of the flat roof. The flat roof, in particular the fall protection structure, may be adapted to allow at least one person to carry out maintenance. The flat roof may be adapted to be sustainable, economical and/or efficient. The flat roof may be adapted to improve fall protection for at least one person on the flat roof or in vicinity of the building. The flat roof, in particular the fall protection structure, may protect or prevent a person from, in particular accidentally, falling from the flat roof. The fall protection structure may be adapted to protect or prevent object
