Rosendin Electric Announces The Deployment Of Ampt String Optimizers To Repower Utility PV System

The utility-owned power plant at Arizona Western College was first commissioned in 2011 under a 30-year power purchase agreement (PPA). Rosendin Electric installed Ampt String Optimizers to repower the six-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.

"As PV plants degrade over time, we take advantage of the latest technologies to enhance systems for our customers," said Brian Smith, Service Division Leader at Rosendin Electric. "Ampt optimizers not only repower systems like Arizona Wester College to enhance performance and generate more revenue, they also provide a low-cost way to upgrade legacy inverters in the future as each one ends its lifecycle with the newest inverter technology."

Rosendin Electric brings a range of engineering, installation, and operations and maintenance (O&M) services to PV power plant owners by leveraging its nation-wide service organization. The company's repowering service provides a complete solution to customers that includes an initial site evaluation and degradation analysis, electrical planning, installation and recommissioning.

"Since announcing our repowering solution with Ampt in July, we have been contacted to support over a gigawatt of existing PV sites in the U.S.," said Rosendin's Mr. Smith, "We expect that project list to grow rather quickly given the attractive return on investment to project owners."

"The recent deployment of our optimizers at Arizona Western College demonstrates the end-to-end repowering capabilities that Rosendin Electric and Ampt uniquely bring to the market," said Levent Gun, CEO of Ampt. "We look forward to partnering with their team on upcoming projects."
