Your neighbors in Stillwater are going solar
Your neighbors in Stillwater are going solar, from the bluff-top homes on North Hill and South Hill above downtown to the newer houses spreading west toward Manning Avenue and Highway 5. iSolar is a family business based in nearby Saint Paul Park, so the St. Croix Valley is basically our backyard. We’ve wired systems into century-old homes in Stillwater’s historic core and into plain ranch roofs a few miles out, and the two jobs don’t look anything alike: different roof pitch, different shading, different permitting path. We’re a local crew of Minnesotans, the same family that picks up on the first call is the one standing behind your system in year 30. Whether you’re on North Hill, South Hill, or out past town, we already know what your roof is going to throw at us before we show up.
Where solar produces best in Stillwater
Stillwater sits down in a river valley, and that shapes solar more than in almost any other city we work in. Homes along the bluffs downtown and up on North Hill and South Hill often have steep, complex rooflines, gables, dormers, and mature trees planted decades before anyone thought about kilowatt-hours, so those roofs need real site-specific design instead of a cookie-cutter layout. Head west toward Manning Avenue and Highway 5 and the roof lines open up: newer construction with simpler trusses, better southern exposure, and a lot less shading to fight. Both spots can produce good power, but the design conversation is different, and we walk the site with a shading tool before we ever draw a layout, not a satellite photo.
On the older bluff homes we lean on microinverters or power optimizers, so one shaded panel under a maple canopy doesn’t drag down the whole array’s output the way it would on a single string inverter. On the bigger lots west of town, a ground-mount array is sometimes the better call, especially where the house roof is small, oddly angled, or already crowded with vents and dormers. We size each option against your actual roof and your electric bill, not a generic template.

Is your Stillwater place a good fit?
We look at what actually drives production in Stillwater (Washington County).
Homes & roofs
Stillwater’s housing stock spans two eras: steep-roofed homes from the 1880s to 1920s packed into the historic bluff neighborhoods downtown, and simpler ranch and two-story construction from the last few decades further west. We’ve worked on both. Older roofs usually need a closer structural and shading review before we finalize a layout.
Trees & shading
The river valley’s mature oak and maple canopy is part of what makes downtown Stillwater what it is, and it’s also the biggest factor in solar output there. We run a full shading study on every bluff-area roof; homes further west with younger trees and more open yards usually see less of a hit.
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 Stillwater system for the full year.
Local power & incentives
Stillwater homes and businesses are on Xcel Energy’s grid, and most residential solar here interconnects through Xcel’s Solar*Rewards program. Stillwater also joined Xcel’s Partners in Energy program in 2023 to help residents cut energy use and costs. We handle the Xcel interconnection paperwork start to finish.
Local design, honest numbers
We design each Stillwater 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.

Frequently asked.
Does solar still work through Minnesota winters in Stillwater?
Yes. Panels actually run more efficiently in the cold, snow slides off the smooth glass, and our honest Stillwater estimates already bake in winter losses. Strong spring-through-fall production more than makes up for the short December days.
Which utility serves Stillwater, and do you handle the paperwork?
Xcel Energy (Northern States Power Company) is the electric utility for Stillwater; the city itself only runs water and sewer, not electric. Most home solar systems here interconnect through Xcel’s Solar*Rewards program, and Stillwater is also enrolled in Xcel’s Partners in Energy community energy planning program. Yes, we handle the Xcel interconnection application, net metering agreement, and inspection scheduling for you.
My Stillwater 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 Stillwater 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 Stillwater-area businesses, farms and acreage. Same local family crew.
How do I get a real number for my Stillwater property?
Book a free, no-pressure assessment. We review your roof or land, your utility usage and your goals, then give you honest production and savings figures — for a home, business or farm. Call (651) 565-1140 or request your estimate online.
Does Stillwater’s historic downtown district affect solar permitting?
If your home sits inside Stillwater’s National Register-listed Downtown Commercial Historic District or the Downtown Design Review Overlay District, exterior alterations need Design Permit approval from the city’s Heritage Preservation Commission, and solar visible from the street would likely fall under that review, even though the city’s guidance doesn’t call out panels by name. Outside that small downtown core, including the Neighborhood Conservation District covering a lot of Stillwater’s older residential streets, that extra review generally isn’t triggered by roof-mounted solar. We check your address against the district map before designing anything.
