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 experiments were installed on the docking module during STS-76, and retrieved during STS-86. Mir Docking Module The Stykovochnyy Otsek (, ), GRAU index 316GK, otherwise known as the "Mir" docking module or SO, was the sixth module of the Russian space station "Mir", launched in November 1995 aboard the . The module, built by RKK Energia, was designed to help simplify space shuttle dockings to "Mir" during the Shuttle-"Mir" programme, preventing the need for the periodic relocation of the "Kristall" module necessary for dockings prior to the compartment's arrival. The module was also used to transport two new photovoltaic arrays
