Union Distributing unveils largest solar plantPhoenix Business Journal
PrintEmailReprintsRSS FeedsLinkedInShareCommentsUnion Distributing flipped the switch on what the company calls the largest solar system owned by a petroleum distributor, split between locations in Phoenix and Tucson.

The Tuesday event at the $1.6 million project officially christened the 150-kilowatt system at the company’s Phoenix location and the 103-kilowatt system at the Tucson location.

The system is the largest installed by Solar Hawk energy with contractor Wilson Electric and will produce 400,000 kilowatt hours of electricity annually and provide up to 90 percent of the power needed to run the facilities.

The distributor was able to pay for the project through tax rebates and the Salt River Project’s Earthwise Solar commercial program, which provides rebates for solar systems.
