Eaton Utility-Scale Balance of System Solutions Help Illinois Solar Farm Reduce the Costs of Solar Energy

Eaton Utility-Scale Inverter Reduces Installation Costs, Maximizes Energy Harvest and Optimizes Maintenance

PITTSBURGH … Diversified industrial manufacturer Eaton was tapped by Rockford Solar Partners in Rockford, Ill. to provide utility-scale balance of system (BOS) electrical distribution equipment for a 3.06-megawatt (MW)solar farm at the Chicago-Rockford International Airport. The project will be part of a 62-MW solar farm and the largest airport-based solar generation facility in the United States. It is projected to reduce carbon emissions by 24,000 metric tons annually. The installation incorporates two skid-less Eaton Power XpertTM Solar 1500 kilowatt (kW) inverter stations, Cooper Power System transformers and switchgear, as well as Eaton combiner boxes and field service support.

"The solar farm in Rockford is supporting energy independence and helping to create jobs and fuel economic growth," said Michael Pontarelli, senior vice president, Project Development at New Generation Power – a part of Rockford Solar Partners. "We selected Eaton to provide balance of system solutions because it has been an energy management leader and stands behind its solutions for the long term."

Eaton solutions are designed to cut installation time by 50 percent, wiring losses by a factor of two and reduced overall costs for the system. In addition to reducing installation time and costs, the Rockford Solar Project demonstrates how developers and engineering, procurement and construction (EPC) contractors can increase solar harvest using utility-scale technology.

"The Rockford project demonstrates the ability of a utility-scale solar balance of system solutions to reduce the cost of solar energy, propel grid parity and reduce dependence on fossil fuels," said Kleber Facchini, product manager at Eaton. "Eaton is working with Rockford Solar Partners to create a cost-effective model of renewable implementationthat can be replicated across the nation."

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
