Driving headlong on Interstate 5 past the Baldock rest area south of Wilsonville, you catch a glimmer out of the corner of your eye that looks a little like shimmery water in the middle of farm fields. Unless you stop to get coffee or stretch your legs, and then make your way to the back of the rest area, you’ll likely miss the fact that the shimmery thing is almost 7,000 solar panels. Years of planning, many partnerships and $10 million have created the 1.75-megawatt Baldock Solar Highway Project, the second project developed under the Oregon Solar Highway Program and the largest of its kind in the nation. The array at the 1-5/I-205 interchange was the nation’s first solar highway project. Construction on the Baldock project began Aug. 23, 2011, and the array went online Jan. 17, 2012. In between, we documented how a unique solar project was built.

How the power flows

The power from groups of solar panels goes into a collector panel on the racking system, which then feeds back to DC switchgear cabinets. The DC switchgear cabinet is then connected to a solar inverter that converts the DC power coming from the solar panel to AC power. The power then goes into an AC switchgear cabinet that feeds out to a PGE 2000KVA transformer.

“If you can put solar at the exchange of two major interstates, you’ve taken a mountaintop. In public service, you aren’t rewarded for taking risk. This had never been done before. The 1-5/I205 solar project was the first in the Americas. [These agencies] have never been engaged in this before. This array takes us beyond the era of the dinosaur, where we are dependent on oil. With the solar highway, we are saying we have a choice. We’re using energy not taken from the earth but given to us by the sun.’’ -Lynn Frank, President, Five Stars International
