Power Spacecraft power is provided by the solar panels which contain 11.42 square meters of silicon cells. The originally planned power was to be 660W at 1.5AU but a faulty connection has reduced the amount of power available by 30%, to about 460W. This loss of power does not significantly affect the science return of the mission. Power is stored in three lithium-ion batteries with a total capacity of 64.8Ah for use during eclipses. The power is fully regulated at 28V, and the Terma power module (also used in Rosetta) is redundant. During routine phase, the spacecraft's power consumption is in the range of 450–550W.
