editDetails of the photovoltaic arrays are described below: "" Two photovoltaic arrays" are powering the spacecraft. The station uses a 28 volt DC power supply which provids 5~, 10~, 20~ and 50amp plugs. When the station is in direct sunlight, several solar arrays charged the nickel-cadmium batteries installed onboard. The arrays are sun orientating on half of a full circle yawn, gouverned by sensors and electrical motors installed in the mounts. When all-sky sensor detects dark, the arrays searcxh an optimal angle for increasing the light input when passing out of the shadows. Each set of batteries with a capacity of 60Ah, are then used to power the devices on-board until the arrays fix to the sun.
The solar arrays themselves were mounted with the Kvant-1 module on the core module in 1987, to provide an additional area of 22square metres.
In 1996 the Space Shuttle Mission #74 carried out more improved AsGa couple of sets of arrays on a joint effort with the Soviet Space Administration NRGia. In this image there is a lattest photovoltaic structure of arrays from 1997 when Mir was finally grounded on Earth, both with arrays, batteries and assembled spetrographay onboard.
