Holding device for holding photovoltaic module of photovoltaic system mounted on building roof, has rails forming channel and pipe or hose connected with each other, where rails are traversed by heat transfer medium in installed state

摘要

The device has rails (1) forming a channel and a pipe or hose (3) connected with each other. The rails are traversed by a heat transfer medium in an installed state. Hollow profile rails are used for mounting photovoltaic modules, where ends of the rails are provided with a seal and a coupling device (2) for the pipe. Heat conducting elements (101) are slid into grooves in the profiled rails. The rails are mounted on the surface using a thermally insulating spacer, so that water drains from the rails. Openings are arranged in a ridge, so that a roof side holds a module box. An independent claim is also included for a photovoltaic system comprising a photovoltaic module.
