Narrative:

I arrived at the helena, mt airport at XX00 am for a flight to great falls, mt to pick up freight. After preflting my aircraft I started the aircraft and began to taxi to the north between a row of t-hangars and a row of parked aircraft. The sun was just coming up over the mountains in the northeast making visibility on the right side of the aircraft difficult. I taxied by several aircraft. After passing the last aircraft I turned right to the runup area and struck an small aircraft aircraft that was parked 2 spaces passed the aircraft in the last tie-down space. I never saw the small aircraft until it was in view on the left side of the windshield. I believe the factors contributing to this incident were the position and the angle of the sun, and the restr visibility on the right side of the aircraft. I think a centerline strip in the tie-down area with turn lines allowing you to know when you had passed the last tie-down spot would have prevented this incident from happening.
