Each ISS solar array wing (often abbreviated "SAW") consists of two retractable "blankets" of solar cells with a mast between them. Each wing uses nearly 33,000 solar cells and when fully extended is in length and wide. When retracted, each wing folds into a solar array blanket box just high and in length. The ISS now has the full complement of eight solar array wings. Altogether, the arrays can generate about 240 kilowatts in direct sunlight, or about 84 to 120 kilowatts average power (cycling between sunlight and shade).
