Project Description

STC Warehouse Inc. is a second-generation warehousing, distribution, and logistics firm with locations in St. Louis, MO; Columbus, OH; and Nashville, IL. They provide public and contract warehousing, carton stapling, and carton stitching for companies such as Anheuser-Busch. To offset energy usage and costs, STC installed solar arrays in both the St. Louis, MO and Nashville, IL locations with this particular spotlight focusing on the larger facility in St. Louis, MO.

Installation Details

STC’s solar array has an estimated production of 203,165 kWh’s, provided by 386 Axitec 370w modules, one SolarEdge 100 kW inverter, paired with two Solar Edge 20 kW’s inverters. It’s mounted on an Ecolibrium flat roof system, using a tilt in the racking to get optimum sunlight exposure. Various rebates and incentives dramatically lower the install cost and make for a quicker payback period.
