Photovoltaic mounting system Photovoltaic mounting system Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV). The solar array of a PV system can be mounted on rooftops, generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle. If the panels are planned to be mounted before the
Mir Docking Module November, leaving STS-71 as the only Shuttle-"Mir" docking mission requiring "Kristall" to be relocated. In addition to simplifying space shuttle docking missions, "Mir"'s docking module was also used as a carrier for two new photovoltaic arrays, mounted to the module in boxes, which were later deployed on "Kvant"-1 during spacewalks. The first, the "Mir" Cooperative Solar Array, was jointly designed by NASA and Russia in order to test designs for the future International Space Station. The array was 42 m² in area, and provided 6.7 kW of power when installed on the station during expedition EO-21 in 1996. The array
