Solar Installation in Wisconsin Rapids, Marshfield and Wood County

Updated October 2026. Northwind Solar, a worker-owned installer based in nearby Amherst, has completed 110 projects in Wood County since 2008. That includes 36 in Wisconsin Rapids, 36 in Marshfield, 7 in Nekoosa and 5 in Auburndale. We have connected 31 projects to Marshfield Utilities and 21 to Wisconsin Rapids Water Works & Lighting, so we know both city utilities' interconnection steps.

We also serve Port Edwards and the farms and rural homes in between.

What kinds of solar projects are common in Wood County?

Our 110 Wood County projects total about 1,200 kW, so most are home-sized systems. The mix changes as you move across the county:

  • Wisconsin Rapids and Marshfield. 72 projects between the two cities. Both cities run their own electric utilities, which affects paperwork and how excess solar is credited.
  • Nekoosa and Port Edwards. 7 projects in Nekoosa so far. On older homes we check roof age first, because it is cheaper to re-roof before panels go up than after.
  • Auburndale, Arpin and the dairy country around Marshfield. Barns, heifer sheds and shops with big roofs. Many farms have daytime loads such as milk cooling and ventilation that match when solar produces.
  • Rural acreage. Ground mounts are common where the house roof is shaded or small. They also make snow clearing and future expansion easier.

Farm owners, note: Under USDA's Rural Energy for America Program (REAP) final rule (published October 1, 2026), projects must be finished 12 to 24 months before you apply, with 12 months of production data. Ground-mounted solar on certified cropland is not eligible, and neither are systems with components made in a foreign-adversary country. Roof-mounted farm systems, or ground mounts on non-crop land, may fit better. Focus on Energy's 2026 business rebate also pays $600 per kW up to $2,400, then $50 per kW above that, up to $25,000, for systems on a non-residential meter.

How does solar work with Marshfield Utilities or Wisconsin Rapids Water Works & Lighting?

Marshfield Utilities and Wisconsin Rapids Water Works & Lighting are both city-owned public power utilities. Each sets its own rules for connecting customer-owned solar and for crediting the extra power you send back, within limits set by the Public Service Commission. We have worked through both utilities' interconnection processes many times.

Because both utilities participate in Focus on Energy, their customers can qualify for the 2026 home solar rebate: $600 per kW, up to $2,400, for home systems purchased and installed in 2026. The federal homeowner credit ended for systems installed after December 31, 2025.

In recent years, several Wisconsin city-owned utilities have asked the Public Service Commission to change how they pay for solar exports. So before you sign, we pull your utility's current terms and build them into your savings estimate. If you live outside the two cities, your bill may come from another utility or an electric co-op; we work with those too. See our net metering explainer.

Solar planned for Wood County

Different parts of the county call for different designs. Here is what we plan for.

Two city utilities, one installer

Marshfield and Wisconsin Rapids each run their own electric utility. We have connected 52 projects between them, so we know which forms, meters and approvals each one needs. We handle that back-and-forth for you and keep you posted until the utility gives the final go-ahead.

Dairy and farm operations

Farm roofs and daytime loads can make solar pencil out. We look at your meter setup, which buildings use the most power, and whether a business rebate or a USDA REAP application fits. We will tell you plainly if the numbers don't work.

Ground mounts on acreage

About 195 of our projects statewide are ground mounts. On rural lots they avoid roof shade, face due south, and are easy to brush off after snow. Before we dig, we plan the trench route to your house or shop, property-line setbacks and room to add panels later.

Backup for storms

Summer storms and winter ice can take down rural lines. A battery can keep a well pump, sump pump, furnace and fridge running until the power comes back. 143 of our projects include storage, using Tesla Powerwall 3, FranklinWH and Enphase batteries. See solar plus storage.

Frequently Asked questions

Has Northwind Solar installed solar in Wisconsin Rapids and Marshfield?

Yes. Since 2008, Northwind Solar has completed 110 projects in Wood County, including 36 in Wisconsin Rapids, 36 in Marshfield, 7 in Nekoosa and 5 in Auburndale. We have connected 31 projects to Marshfield Utilities and 21 to Wisconsin Rapids Water Works & Lighting.

Can Marshfield Utilities or Wisconsin Rapids Water Works & Lighting customers get the Focus on Energy rebate?

Yes. Both utilities are on Focus on Energy's participating-utility list. For 2026, the home solar rebate is $600 per kW, up to $2,400, for qualifying home systems purchased and installed in 2026. You must apply within 60 days of the system starting up and no later than January 31, 2027.

What will my utility pay me for extra solar power?

It depends on your utility's current tariff. City-owned utilities like Marshfield Utilities and Wisconsin Rapids Water Works & Lighting set their own terms with Public Service Commission approval, and those terms can change. We look up your utility's current terms and use them in your savings estimate instead of a generic number.

Can I use a USDA REAP grant for solar on my dairy farm near Marshfield?

Possibly. Under USDA's REAP final rule (published October 1, 2026), projects must be finished 12 to 24 months before you apply, with 12 months of production data. Ground-mounted solar on certified cropland is not eligible, and neither are systems with components made in a foreign-adversary country. A barn or shed roof, or a ground mount on non-crop land, is often a better fit. Application windows are announced in USDA's annual program notices.

Is a ground mount or a roof mount better for a rural Wood County property?

A roof mount usually costs less if your roof is in good shape, faces south or west, and has little shade. A ground mount makes sense when the roof is shaded, small or due for replacement, or when you want room to expand. Ground mounts are also easier to clear after snow.
