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.
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
