Solar for Cottage Grove families, businesses & farms.
Local, family-owned solar, battery and EV charging for Cottage Grove — 4.9 stars, 30-year warranty, the same crew start to finish.
Your neighbors in Cottage Grove are going solar
Cottage Grove is basically our neighbor, Saint Paul Park sits right on your northern border, so when we say we’re local, we mean it literally. We’ve put panels on roofs from the older streets near Hamlet Park and River Oaks Golf Course, where houses have had a couple decades of shingle wear, out to newer subdivisions pushing east toward Jamaica Ridge and the Highlands. Different housing stock, different roof ages, same drill every time: we walk the roof, check the panel, and give you a straight answer about what a system there will actually produce. Being five minutes from your driveway means if something needs a second look after install, we’re not driving in from Minneapolis to do it, somebody from our crew already knows the neighborhood.
Where solar produces best in Cottage Grove
Cottage Grove’s roofs split pretty cleanly into two eras. The older river-town core near the Mississippi River bluffs and 80th Street has more mature tree canopy and sometimes more cut-up rooflines, still workable for solar, but it usually means a closer look at shading and panel placement during the site visit. The newer subdivisions out toward the Highlands and Ravine areas tend to have simpler roof shapes, cleaner south- and west-facing slopes, and younger trees, which generally means more usable roof space and less design compromise. Either way, what we’re hunting for is a roof plane with a clear shot at the sky, in a city this spread out, that varies block to block, not just neighborhood to neighborhood.
A handful of larger parcels out toward Grey Cloud Island and the river bottoms have room for ground-mounted arrays, Cottage Grove’s city code allows it on lots of five acres or more, and we handle the height and setback rules as part of permitting. For everyone else on a standard city lot, that means roof-mount, and if your roof has multiple faces or partial shade from mature trees, microinverters let each panel produce on its own instead of one shaded panel dragging down the whole string.

Is your Cottage Grove place a good fit?
We look at what actually drives production in Cottage Grove (Washington County).
Homes & roofs
Cottage Grove’s housing stock ranges from established streets near Hamlet Park and 80th Street to newer construction toward the Highlands and Jamaica Ridge. Roof ages and pitches vary block by block, so we don’t quote off a satellite photo, every proposal starts with an actual roof inspection.
Trees & shading
Older sections of town near the river bluff carry more mature tree canopy, which can shade part of a roof for part of the day. Newer east-side subdivisions generally have younger trees and more open sky. Either way, we run a real shading analysis on your specific roof before we design anything.
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 Cottage Grove system for the full year.
Local power & incentives
Cottage Grove is Xcel Energy territory for both electric and gas service. Xcel’s Solar*Rewards program is the production-based incentive most homeowners here use, and net metering credits what your system sends back to the grid. We handle the interconnection application and Solar*Rewards paperwork so you’re not stuck on hold with Xcel.
Local design, honest numbers
We design each Cottage Grove 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 Cottage Grove
Pairing storage with solar keeps your Cottage Grove home or business powered through outages and banks your daytime production for the evening. We size it to what matters most to you.

Frequently asked.
Does solar still work through Minnesota winters in Cottage Grove?
Yes. Panels actually run more efficiently in the cold, snow slides off the smooth glass, and our honest Cottage Grove estimates already bake in winter losses. Strong spring-through-fall production more than makes up for the short December days.
Which utility serves Cottage Grove, and do you handle the paperwork?
Xcel Energy serves Cottage Grove for both electricity and gas, we haven’t found any co-op or municipal power overlap in the city. Once your system’s designed, we submit the interconnection application to Xcel on your behalf, enroll you in their Solar*Rewards incentive program, and handle the net metering paperwork so your bill actually reflects what your panels send back to the grid. You don’t have to call Xcel yourself.
My Cottage Grove 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 Cottage Grove 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 Cottage Grove-area businesses, farms and acreage. Same local family crew.

Does Cottage Grove allow ground-mounted solar, or does every system have to go on the roof?
Cottage Grove’s city code allows ground-mounted solar, but only on lots of five acres or more, with a 15-foot height cap, setback rules, and no front-yard placement. Roof-mounted systems have their own rules too, panels must sit flush and parallel to the roofline, can’t extend past the roof edge, and need to blend in color-wise. Every install needs a city building permit with a site plan, and larger community-solar-scale ground systems need an interim use permit. We prepare and file that paperwork as part of your project.
