McElroy Metal Inc., Bossier City, La., recently completed a retrofit installation and 500-kilowatt photovoltaic (PV) project on its manufacturing facility in Peachtree City, Ga.

The 34-year-old, 30,000-square-foot galvanized R-panel metal roof system was retrofitted with McElroy Metal's 238T symmetrical standing-seam metal system installed by Paramount Metal Systems, Little Rock, Ark., followed by the installation of 1,960 PV panels on the plant's roof and parking lot canopy.

The project is part of Georgia Power's Medium Scale Georgia Power Advanced Solar Initiative. The energy created by the half-megawatt PV system will be sold back to Georgia Power.
