Simon Property Group, Inc. operates malls all across the U.S. The company is based in Indianapolis, IN. That’s where I hail from. Here is a outtake;

Indianapolis-based Simon Property Group Inc. (NYSE: SPG) has completed the largest solar facility installation by a shopping mall owner in the U.S. Simon has entered into a purchase power agreement with Element Markets for the output of the solar facility on the roof of The Shops at Mission Viejo in California. It took less than a month to finish the 173 kilowatt project.

I did not see anything about project costs or potential savings. What I would love to see is real time energy production. Something like the sunnyboy web portal would be perfect.
