Agricultural solar for Montana farms and ranches

The barn, the shop, the pumps, the coolers, the house. One system sized to cover all of it, so you stop paying the utility for electricity.

The whole operation, on power you make yourself.

Every month you send the utility a check for electricity you could be making on your own land. On a working property that check is large, and it only goes up. Flathead Electric raised rates 5.5 percent in June 2026. A solar system ends that. You make your own power at a fixed cost per kilowatt‑hour that sits below the utility’s rate today and never climbs. Once the system is paid off, every kilowatt‑hour it makes is free, year after year, from equipment you own outright on land you own outright. The sun does not send a bill.

We size every system to take care of 100 percent of the operation’s electricity over a full year, winter included. We start from twelve months of your real bills, because farm loads move with the seasons and a system sized off July disappoints in January. Then we look at your buildings and your ground and put the pieces together. Here is what can go on a working property.

Barn and shop roofs. The simplest solar on a working property. A barn or shop roof is big, simple, and unshaded, with none of the vents and dormers that complicate a house. One south-facing barn roof can carry enough panels to run the whole place. We check the pitch and the direction and whether the structure carries a heavy snow year, then mount the array so it sheds snow and stays out of your way.

Ground mounts. If the roofs face the wrong way or you would rather keep them clear, you have ground. A ground‑mounted array sits on a corner you are not using, faces the direction and sits at the tilt that make the most power. It stands on concrete piers and racking engineered for your site. Easy to clear, easy to expand later, and it never touches a roof.

Two-axis trackers. A tracker follows the sun from morning to evening and tilts with the seasons. That is up to 40 percent more energy from the same panels than a fixed array, which means fewer panels to buy for the same production, or more power off the same footprint. Where a site allows both, we quote fixed and tracking side by side with the production numbers, so you pick with the math in front of you. The trackers in the photo below stand in hay ground on a Flathead ranch.

Battery backup. Then there is the day the line goes down. With batteries, the stock water keeps pumping, the coolers keep running, and the house stays warm while the rest of the valley waits for the utility truck. On a ranch that is the difference between a bad afternoon and a lost herd. We build on Enphase batteries and microinverters, one system from one maker. Batteries can go in with the array or later; every system we build is set up to take them.

Off-grid pumps, wells, and outbuildings. Some loads sit a long way from the nearest pole: a stock tank in the back pasture, a well, a shop on a far parcel, a cabin. Running a line out there costs more than the power it will ever carry. A standalone solar and battery system runs that pump or lights that building with no line at all. We size them for January.

We have built this for operations like yours. The Better Beef ranch project and the 78-panel array on Nelson’s Ace Hardware were both ours. Our own crew designs your system and installs it, and we service what we sell, so nothing gets lost between a salesman and a crew. More than a hundred systems in northwest Montana since 2017, and every review Northstone has on Google is five stars. Labor and every piece of equipment carry a warranty. The consultation is free, and the proposal shows the production numbers before you decide anything.

Questions about agricultural solar

Will solar really cover the whole operation?
Yes, when it is sized right. We design from twelve months of your real bills, not a summer snapshot, so the array produces a full year of what you use. On a property with a big roof or open ground, there is almost always room to get there.
What happens to my power bill?
The energy charge goes away. Your utility still connects you and still bills its base and demand charges for the line, but the power itself you make, and when the system produces more than you use, the extra goes back to the grid. Once the system is paid for, the electricity is free.
Does solar work on a barn roof?
Better than on most houses. A barn roof is a wide, plain surface with nothing shading it. We check which way it faces and whether it carries a heavy snow year before anything is ordered, so there is no surprise on install day.
What about snow and winter?
Winter is in the math, not a surprise. The system is sized to a full year, panels shed snow, and ground mounts and trackers are set at angles that clear. More than a hundred of our systems have been through valley winters.
How do people pay for it?
Montana exempts up to $100,000 of a system’s appraised value on a barn, shop or other non‑residential building from property tax for ten years, and $20,000 on the house. The state’s AERLP loan runs 3.5 percent fixed, up to $40,000 over ten years. Clearwater Credit Union’s solar loan is another route, and we have worked with Whitefish Credit Union and Glacier Bank. USDA REAP grants are paused as of March 2026 with guaranteed loans still available; we have taken projects through REAP before and will again if the new rules keep solar eligible. Bring your bills to the consultation and we lay out what fits.
What if I want to lease land to a solar developer?
That is a different business and we are not in it. This is about power for land you already work.
