Yes and no. The original plan intended that Philae would have power due to being in the sun, but the lander bounced off of the comet and landed in a different place then expected, in the shadow of rough terrain.

Due to this the original set of experiments had to be completely run on battery, although the battery capacity was not intended for this.

So ESA had to hibernate it early, hoping one day it would get enough sunlight to be able to operate again, and allowing them to do more experiments – which happened now.
