Project Description:
Cox Enterprises successfully used HOLT Renewables to install solar at its Manheim Auto retail locations across the US to reduce energy bills while supporting aggressive company sustainability initiatives. In 2012, Manheim Auto San Antonio faced high energy costs from CPS Energy, San Antonio's utility company. Limited incentives required a phase approach to maximize rebates. Manheim required that the roof-mount system not violate their roof warranty, create any structural problems, or have an impact on ongoing auto auction activities.
The system uses 238 Phonosolar 310 watt panels and two Solectria 28kW inverters which convert the DC electricity from the panels into AC power. Most of the system utilizes a Unirac ballasted solution that does not penetrate the facility's roof membrane, and a small portion of the system was flush-mounted to a standing seam metal roof part of the structure.
