The facility houses Fronius USA’s over 100 employees and has recently installed a rooftop array. The large array not only serves the large facility’s energy demands, but assists in the company’s product research and development in the US.

Fronius USA is the leader the inverter industry, with a full product line that compliments the needs of all aspects of solar: from the small family home to the largest of commercial facility or solar farm.
