Photovoltaic system the outer edge. Electrically connected and mounted on a supporting structure, solar modules build a string of modules, often called solar panel. A solar array consists of one or many such panels. A photovoltaic array, or solar array, is a linked collection of solar modules. The power that one module can produce is seldom enough to meet requirements of a home or a business, so the modules are linked together to form an array. Most PV arrays use an inverter to convert the DC power produced by the modules into alternating current that can power lights, motors, and other loads.
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
