Oregon State University has recently brought the largest of its ground-mounted solar arrays online as part of the Oregon University System’s “Solar by Degrees” program.

The university now has three solar project sites in Corvallis covering some 10 acres collectively that have the capacity to generate more than 2.6 million kilowatt-hours of power per year. The system not only provides cost savings by providing solar energy for less than current utility power rates, it helps Oregon State reduce its carbon footprint in a way that doesn’t cost the university money up front.

The arrays were constructed and are owned and operated by SolarCity, which has worked with OSU and the Oregon Institute of Technology for several years on the Solar by Degrees programs. The company’s collaboration with OSU has not been limited to the Corvallis campus, according to Brandon Trelstad, the university’s sustainability coordinator.

“The way the partnership works is that SolarCity installs the solar arrays at no cost to the university, and OSU simply pays for solar energy that they produce – at a lower rate than they would pay for utility power,” Trelstad said.

This past fall, SolarCity completed a 431-kilowatt installation at OSU’s Hermiston Agricultural Research and Experiment Station in Eastern Oregon, and another 221-kilowatt solar project at the North Willamette Research and Extension Center in Aurora. Annual electrical output from all five OSU solar sites is approximately equivalent to the annual carbon emissions from 255,025 gallons of gasoline or 477 passenger vehicles, according to US Environmental Protection Agency’s Greenhouse Gas Equivalencies Calculator.

Two of the sites in Corvallis have operated for more than a year, but the latest site in Corvallis - which is located near 35th Street and Campus Way – just went online. Each installation is “grid-tied,” which means it seamlessly provides power when the sun shines and blends in utility power when it doesn’t.

At the branch Experiment Stations, the arrays not only save money, they provide an example of how solar power can work in a rural and/or agricultural setting.

The solar array at Hermiston is expected to reduce their electricity costs by about half or about $30,000 in the first year, possibly incresing after that, according to Philip B. Hamm, director of the Hermiston Agricultural Research and Experiment Station.

At two of the three Corvallis installations, the College of Agricultural Sciences is grazing sheep next to the solar arrays, which is how the land previously was used. At the Aurora location, a bee and insect pollinator habitat area is being planned. At the Hermiston location, the area had never been used for research given its irregular shape and lack of water availability, but now benefits the campus to provide solar power in an otherwise unusable space.
