Your neighbors in Northfield are going solar
Northfield’s housing runs the full range, and we’ve gotten to know it firsthand across three installs here. The old blocks east and west of the Cannon River near downtown and Carleton carry 1880s-to-1920s stock: Victorians, American Foursquares, bungalows, steep pitches, and the occasional finicky slate or cedar history to work around. Mid-century growth added ranch and Cape Cod streets farther out, and the newer edges of town, places like Hidden Valley, Mayflower Hill, and Cannon Valley Estates, plus the subdivisions going in east of the river, are two-story colonials and split-levels with simpler, solar-friendly rooflines. On the fringes toward the Rice-Dakota county line you get acreage and hobby farms with real ground-mount potential. Each of those housing types needs a different design approach, and that’s the part we actually enjoy.
Where solar produces best in Northfield
The best producers in Northfield are usually the newer subdivisions: Hidden Valley, Mayflower Hill, Cannon Valley Estates, and the developments east of the river. Houses there are 1990s-and-newer two-stories with large, uncomplicated south- or west-facing roof planes, and the boulevard trees planted with them are still young enough that shading is minor. Mid-century ranch neighborhoods can also do well because ranch roofs are long and low with plenty of usable area, though the trees on those blocks are now 60-plus years old, so it comes down to which side of the street you’re on. A clean south-facing plane at a typical 4/12 to 8/12 pitch is the sweet spot.
The harder cases are the historic blocks near downtown and Carleton, where mature oaks and maples and cut-up Victorian rooflines mean a one-size array won’t work. There we design around the shade: microinverters or optimizers on every panel so one shaded module doesn’t drag down the string, and sometimes splitting the array across two or three roof planes. On acreage outside town, a ground mount often beats the roof entirely, we can set the exact tilt and azimuth and skip the tree problem altogether.
Solar for every Northfield property.
Homeowners, businesses and farms in Northfield each get a system — and incentives — built for them.
Homeowners
Cut your electric bill, lock in your rate for decades, and back it with a 30-year warranty. Net metering banks your summer surplus for winter.
Businesses
Northfield-area businesses stack the 30% ITC, depreciation and demand-charge savings for fast payback — on the roof or on the ground.
Farms & acreage
Northfield-area farms cut costs on irrigation, drying, dairy and the shop with roof, barn or ground-mount solar — plus the 30% ITC, depreciation and current USDA REAP guidance.
Is your Northfield place a good fit?
We look at what actually drives production in Northfield (Rice County).
Homes & roofs
Northfield spans 1880s Victorians and Foursquares near downtown and the colleges, mid-century ranches and Cape Cods in between, and newer two-stories and split-levels in Hidden Valley, Mayflower Hill, and the subdivisions east of the river. Newer roofs tend to be simple asphalt planes; the old stock is steeper and more cut up.
Trees & shading
The historic core has a heavy, mature canopy, beautiful streets, real shading math. Mid-century blocks carry 60-year-old boulevard trees that vary lot to lot. The newer subdivisions and the open farmland edges of town have young or minimal tree cover and the cleanest sun windows.
Sun & seasons
Minnesota produces strong solar spring through fall, and cold, clear winter days are productive too. Snow slides off the smooth panels, and we size every Northfield system for the full year.
Local power & incentives
Nearly all of Northfield is Xcel Energy territory, while some rural properties just outside town sit on Dakota Electric Association co-op lines. For Xcel customers that means net metering and the Solar*Rewards program; Dakota Electric has its own interconnection process. We confirm your utility before design and file all the interconnection and program paperwork ourselves.
Local design, honest numbers
We design each Northfield system around your roof, shading and real usage — premium Tier-1 panels and Enphase microinverters, installed clean and permitted by the same crew that starts the job. No subcontractors, no inflated production promises.
Battery backup in Northfield
Pairing storage with solar keeps your Northfield home or business powered through outages and banks your daytime production for the evening. We size it to what matters most to you.

You get the equipment, engineering and workmanship you'd expect from the big national installers — delivered by a local, family-owned crew that's here for the long haul. Every system is designed and installed by our own team, permitted and inspected, and backed by a 30-year warranty.

Frequently asked.
Does solar still work through Minnesota winters in Northfield?
Yes. Panels actually run more efficiently in the cold, snow slides off the smooth glass, and our honest Northfield estimates already bake in winter losses. Strong spring-through-fall production more than makes up for the short December days.
Which utility serves Northfield, and do you handle the paperwork?
The city of Northfield is served by Xcel Energy, so most homeowners here interconnect under Xcel’s net metering rules and can look at programs like Solar*Rewards. If you’re on acreage outside city limits, especially north toward the Dakota County line, you may be on Dakota Electric Association instead, which has its own process. Either way, yes, we handle the whole application: interconnection agreement, program enrollment, and the meter swap coordination.
My Northfield roof has some shade — can I still go solar?
Often yes. Per-panel microinverters keep your unshaded panels producing even if a tree shades part of the roof, and we map your roof's sun before we design. If shade is heavy, we'll tell you straight and look at a ground-mount where there's room.
Do you do business and farm solar in Northfield too?
Yes — alongside home solar we install commercial systems (with the 30% ITC, depreciation and demand-charge savings) and agricultural or ground-mount solar for Northfield-area businesses, farms and acreage. Same local family crew.

My house is in one of Northfield’s historic districts near downtown. Can I still put solar on it?
Usually yes, but plan on one extra step. Northfield takes its historic preservation seriously, and work on designated properties in the historic district can require review by the city’s Heritage Preservation Commission before a permit is issued. In practice, panels on rear-facing or street-hidden roof planes are the easiest approvals. The good news: Northfield earned a SolSmart Silver designation in 2021 partly for streamlining its solar permitting, so the city process is friendlier than most. We prepare the drawings and handle the permit and any review submittals for you.
