Watch the Exotic Tension online guitar lesson by Tony Smotherman from Essentials: Power Ballad Soloing
We're making use of simple pedal points in the opening of the track. You can expand on this for a wealth of ideas on other string sets. Notice the low string bending, this can give a very vocal like quality to your solos instead of staying in the higher register all the time. I also create a moving melodic motif by simply ascending a C minor scale without the 4th or b7 in octaves. This is a nice way to create an inspiring sound in your solo.
