Photovoltaic mounting system at the same angle as the latitude of array's location to maximize the annual energy yield of module. For example, rooftop PV module at the tropics provides highest annual energy yield when inclination of panel surface is close to horizontal direction. A study in the tropics showed that the orientation of low-slope rooftop PV has negligible impact on annual energy yield, but in the case of PV external sunshade applications, east façade and panel slope of 30–40° are the most suitable location and inclination.

Mir Docking Module 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 to the station, as a mounting point for external experiments, and as a
