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.

Poisk (ISS module) Poisk (ISS module) Poisk (; lit. "Search"), also known as the Mini-Research Module 2 (MRM 2), , or "МИМ 2", is a docking module of the International Space Station. Its original name was Docking Module 2 ( (SO-2)), as it is almost identical to the Pirs Docking Compartment. Added in 2009, "Poisk" was the first major Russian addition to the International Space Station since 2001. Poisk is overall the same design as a docking module Pirs. Whereas Pirs has been attached to the "nadir" ("bottom") port of "Zvezda" module, Poisk is attached to the "zenith" ("top"); Pirs is closer to
