Definitions

• the invention relates to an arrangement for mounting solar panels on a tile roof as defined in the preamble of claim 1 and to a method of mounting solar panels on a tile roof as defined in the preamble of claim 8.
• the invention is especially applicable for fastening struc tures, such as solar panels intended to be installed on a tile roof, onto the tiles of the roof.
• the solution according to the invention is well-suited for mounting solar panels on finished tile roofs.
• Retrofitting different kinds of struc tures to tile roofs is usually difficult due to the brittle and easily cracked nature of the material of roof tiles.
• the tile roof is a pitched roof and consists of roof tiles made from stone material and laid to overlap each other.
• the tile roof is a structure consisting of loosely joined roof tiles and, as such, cannot take high loads.
• the material of the roof tile makes it a high risk, inter alia, to drill holes in the roof tile, or to make other kinds of connections thereto. There is a real risk of causing the tile to crack while worked on.
• the roof tiles are laid on a sturdy assembly made up by roof trusses and battens and carrying the weight of the roof tiles made from the stone material.
• the purpose of the roof tiles is to provide a weatherproof and watertight structure to protect the building.
• the loosely joined roof tiles of the tile roof impose strict requirements if heavy structures are to be mounted on the tile roof.
• the tile roof is retrofitted with something, such as with one or more solar panels or snow guards, they are often attached to an auxiliary batten provided under the roof tiles. Because the auxiliary batten must be installed separately, the ret rofitting is a slow and expensive operation.
• the installation of the auxiliary batten under the roof tiles necessitates that the roof tiles must be removed, for the entire instal- lation period, over the entire length of the auxiliary bat ten.
• This invention aims at eliminating the above-mentioned draw- backs and to provide a novel mounting arrangement and a method, with tile roof mounts, for mounting solar panels on a tile roof.
• An objective thereof is provide a novel way of attachment where no auxiliary batten is needed under the tiles, the roof tiles do not have to be removed for the installation period and the roof tile does not have to be worked on, and where, in addition, the position of the solar panel mounting rails is intended to be such that the solar panel mounting rails can be fastened to roof mounts in a good working position, by using a battery-driven drill, for example.
• another objective thereof is allow for quick first-rate mounting as well as versatile, inexpensive, easy- to-use and firm fastening to a tile roof.
• the arrangement for mounting solar panels on a tile roof according to the invention is characterized in what set forth in the characterizing part of claim 1.
• the method according to the invention is characterized in what set forth in the characterizing part of claim 8.
• Other em bodiments of the invention are characterized in what set forth in the rest of the claims.
• the invention relates to an arrangement for mounting solar panels on a tile roof, the arrangement comprising solar panel mounting rails, such as rail profiles provided with one or more T-grooves, and tile roof mounts for mounting the mount ing rails in place.
• the tile roof mount employed in the arrangement comprises a body part having a fastening plate for fastening the mounting rail to the tile roof mount.
• Each tile roof mount has, at its first end, a fastening lug with fastening holes for fastening the tile roof mount to a roof batten located under the upper end of the underlying roof tile.
• the tile roof mount is adapted to be po sitioned, at its body part, on top of a single roof tile.
• the first end of the tile roof mount has a sub stantially hook-like supporting part including the fastening lug, the supporting part being adapted to extend around the upper end of said roof tile and below said roof tile, to leave, as the fastening lug extends to and contacts the roof batten located under the upper end of said roof tile, an air gap between the hook-like supporting part and the upper edge of said roof tile.
• the fastening plate of the tile roof mount has a fastening surface for fastening the mounting rail to the tile roof mount.
• the fastening surface is adapted to be positioned substantially perpendicularly to the upper surface of the tile roof
• the tile roof mount is designed to be easily fixable to the roof batten located under the roof tile, without removing or working on the roof tile, the fastening surface of the fastening plate being angled to allow a battery-driven drill, for example, to be used for fastening the mounting rail to the tile roof mount.
• the invention also relates to a method of mounting solar panels on a tile roof.
• the solar panels are mounted on mounting rails, such as rail profiles provided with one or more T-grooves and intended to be fas tened to tile roof mounts having a body part with a fastening lug for fixing the tile roof mount in place.
• the tile roof mount is preferably po sitioned, at its body part, on a single roof tile and fas tened, at its fastening lug, to a roof batten located under the upper end of the same roof tile.
• the fastening surface of the fastening plate of the tile roof mount is preferably positioned perpendicularly to the upper surface of said roof tile.
• the second end of the tile roof mount is fastened, if necessary, to a roof batten located under the lower end of the underlying roof tile, by using a separate additional fastening part.
• a major advantage of the solution according to the invention is that the good working position and the possibility of using machine tools make it fast and easy to install.
• the mounting rail used for mounting the solar panels is effortless to fasten to the tile roof mount, by means of a battery-driven drill, for example, since the fastening sur face between the tile roof mount and the mounting rail is not parallel to the roof but substantially perpendicular to the surface of the tile roof, allowing a T-screw acting as a fastening screw to be fastened substantially parallel to the upper surface of the tile roof.
• the arrangement makes it possible to visually check that the T-screw is in the right position, based on the position of the groove provided in the head of the T-screw.
• Another advantage is that the roof tile does not have to be worked on or notched, at the roof mount, reducing the risk of the tiles breaking. Another advantage is that, as a result of that no separate auxiliary battens are needed, the in stallation costs are lower and the installation is quicker.
