Rosendin Electric Teams Up with Leader in Power Conversion Technology on Arizona Western College Project

Sep 25, 2017

Rosendin Electric, a member of the National Electrical Contractors Association and one of the largest electrical contractors in the U.S., is partnering up with a global leader in power conversion technology for the deployment of Ampt String Optimizers to upgrade a large-scale solar photovoltaic (PV) system at Arizona Western College.

The companies announced this week that the deployment is part of Rosendin's recently announced repowering service to increase the production of PV power plants and increase return on investment, according to a report from Markets Insider. The utility-owned power plant at Arizona Western College was first commissioned in 2011 under a 30-year power purchase agreement (PPA), the report added.

Rosendin Electric installed Ampt String Optimizers to repower the 6-year-old PV system. Ampt optimizers are DC-to-DC converters that put dual maximum power point trackers (MPPTs) on each string of PV modules to improve the system's lifetime performance. Ampt's technology recovers energy losses that naturally occur in PV systems as they age. The optimizers were connected to the existing wiring and inverters which allows for rapid deployment without rewiring, trenching or permitting for a significant cost savings.
