The solar rooftop project atop Salt Lake City’s convention center was the result of complicated financing, according to planners, and is expected to provide up to 17 percent of the Salt Palace’s power while serving as a green calling card for energy-conscious conventioneers.

Planners credited attorneys R. Thomas Hoffmann, Darin Lowder, and a team from Ballard Spahr for working long hours and dealing with the intricacies of the tax structure, which required numerous meetings with the Internal Revenue Service and the U.S. Treasury Department.
