Solar Panel Installation in Donald, Oregon
Donald is a city of about a thousand people on four tenths of a square mile of French Prairie farmland, twenty-three miles northeast of Salem with Interstate 5 a mile to the east. It was laid out in 1908 from land claims sold by R. L. Donald, a railway engineer, grew around the Oregon Electric Railway substation completed in 1906, made bricks and tile for a decade, and grew hops. The Portland and Western still runs the line.
The town is small; the parcels around it are not. That is why more Donald projects end up on the ground than on a roof, and ground mounts are a different job with different costs.
When a Ground Mount Is the Right Answer
- The roof is shaded, wrongly oriented, or too small for the consumption
- The roof covering is near the end of its life and the array would have to come off again
- The loads are agricultural — pumps, shops, cold storage — and larger than a house roof can serve
- There is open, low-value ground that is not in the way of equipment
Ground mounts also age better in one specific respect: everything is reachable. Cleaning, inspection and repair happen from the ground rather than from a ladder, which quietly lowers the cost of owning the system.
The Trench Is the Part People Underestimate
The panels are the same panels. What separates a ground-mount quote from a roof quote is the distance between the array and the meter.
Current loses voltage over distance. The further the array sits from the point of connection, the larger the conductors must be to keep that loss within acceptable limits — and copper is priced by the pound. Two hundred feet of trench is not twice the cost of a hundred; it is more than twice, because the wire gets heavier as well as longer.
- Trenching itself: depth to code, and what the machine hits — rock, roots, drain tile, irrigation lines
- Crossing a driveway, a field road or a ditch, each of which adds method and cost
- Conduit, pull boxes and a disconnect at the array, since a detached structure needs its own
- Restoring the ground afterwards, which matters on farmland
We measure the run and price the trench honestly at quote time. A ground-mount quote that does not itemise the trench is not a finished quote.
Siting: Sun, Rows and Staying Out of the Way
Rows must be spaced so they do not shade each other when the December sun is low, which makes the footprint larger than the panel area. On working ground the right site is usually the awkward corner rather than the best field — the wet spot, the odd triangle, the piece the sprayer has to turn around in.
Farm zoning is the other consideration, and it is more permissive than most people expect for an array serving your own property. The detail is on the Dayton page, and we confirm the rules for your parcel with the county before designing.
What Holds It Down
Foundation choice follows the soil. Driven piles or ground screws are quick and disturb little, and suit the deep valley soils around Donald. Concrete piers are the fallback where bearing is poor or the ground is rocky. Ballasted frames avoid excavation entirely but need weight and space. All three are engineered against wind uplift for the site — an array in open farmland catches more wind than one tucked behind a house.

Donald Solar FAQs
Is a ground mount more expensive than a roof array?
The panels cost the same; the difference is racking, foundations and the run back to the meter. Short runs are competitive with a roof install. Long runs are not, because conductors have to grow to limit voltage drop and trenching adds real cost — which is why we price the trench explicitly.
How far can the array be from the house?
Further than most people think, provided the conductors are sized for it. Distance is a cost question rather than a hard limit: we calculate voltage drop for the actual run and size the wire so the losses stay acceptable, then quote the trench to match.
How much ground does an array take up?
More than the panel area, because rows are spaced to avoid shading each other at low winter sun angles. On farmland we site arrays on the least productive corner and keep the footprint tied to your own consumption.
Can I put a ground mount on farm-zoned land?
Usually, when it serves your own property. Oregon’s acreage limits apply to commercial generating facilities selling power to the public, not to net-metered systems for on-site use. We confirm the rules for your parcel with the county first.
