Jones County at a Glance
Jones County is home to 20,646 residents per the 2020 Census, with more recent estimates holding in roughly the same range for this largely rural county. Anamosa is both the county’s largest city and its county seat. Jones County was established in 1837 and named for George Wallace Jones, a U.S. senator and territorial delegate. It covers 576 square miles of east-central Iowa and is officially part of the Cedar Rapids metropolitan statistical area — but its geography is genuinely a crossroads: Jones County borders Linn County (Cedar Rapids) to the west, Dubuque County to the northeast, Delaware County to the northwest, Jackson County to the east, Clinton County to the southeast, and Cedar County to the south, putting it directly between two of SolQ’s strongest existing Iowa markets, Cedar Rapids and Dubuque.
The county’s economy leans on agriculture across its rural townships, with Anamosa and Monticello anchoring most of the manufacturing, healthcare, and retail jobs. Anamosa is home to Grant Wood’s birthplace, the Anamosa State Penitentiary, and the 400-acre Wapsipinicon State Park along the Wapsipinicon River. Monticello hosts the Great Jones County Fair every July, drawing an estimated 100,000 visitors to the fairgrounds in town. For homeowners, that mix means a genuinely rural spread of roof types, electric loads, and utility accounts across a fairly compact county — which is exactly why SolQ designs every Jones County system around the specific address, not a one-size-fits-all county average.
Cities & Towns We Serve in Jones County
Jones County has two incorporated cities that clear Iowa’s 2,500-resident threshold for a dedicated SolQ page — out of nine incorporated communities in the county overall. Tap a city below for the full picture, or keep reading — this page exists specifically to cover the rest of the county, from mid-size towns to the smallest rural crossroads, in one place.
Anamosa · pop. ~5,450 · county seat
Jones County’s largest city and county seat, home to the Anamosa State Penitentiary, Grant Wood’s birthplace, and Wapsipinicon State Park. Split between Alliant Energy and Maquoketa Valley Electric Cooperative, which is headquartered right in town.
Monticello · pop. ~4,040
Jones County’s second-largest city, home to the Great Jones County Fair and Camp Courageous, about 9 miles east of Anamosa. Served almost entirely by Alliant Energy.
Also Serving Jones County’s Smaller Communities
Jones County is home to seven more incorporated communities that don’t (yet) clear the 2,500-resident threshold for their own dedicated SolQ page, but we install there too: Olin (pop. ~651), Wyoming (pop. ~523), Oxford Junction (pop. ~424), Martelle (pop. ~249), Onslow (pop. ~201), and Morley (pop. ~96), per Jones County’s own community listing.
A quick note on Cascade: it’s a real, larger community (roughly 2,386 residents at the 2020 Census) that sits mostly in neighboring Dubuque County, with only a small slice of the town crossing into north-central Jones County. Because Cascade’s primary county is Dubuque, not Jones, and its population sits below the 2,500-resident threshold this site uses for a dedicated city page, we don’t have — and don’t plan — a standalone Cascade page. We do install there, on either side of the county line. If you live in Olin, Wyoming, Oxford Junction, Martelle, Onslow, Morley, Cascade, or anywhere else in Jones County, the FAQ below explains how coverage and utility service work for you.
Electric Utilities Serving Jones County
Jones County runs overwhelmingly on one utility, with two smaller providers rounding out the map — not a clean single-provider county, and we say so plainly rather than rounding up to one company covering everyone.
Alliant Energy
The dominant provider in Jones County by a wide margin, serving an estimated 9,400+ county customers per findenergy.com’s own tracking — 100% of Monticello, Martelle, Morley, Olin, Onslow, Oxford Junction, and Wyoming, plus the large majority (94.20%) of Anamosa itself. Solar production is credited under Alliant’s Rate IO (inflow-outflow) tariff, or a legacy Rate NM net-metering tariff for accounts that already had it. Full detail on our dedicated Alliant Energy solar page.
Maquoketa Valley Electric Cooperative
A member-owned rural cooperative that, despite its name referencing the neighboring Maquoketa area, is actually headquartered right in Anamosa on North Huber Street. Serves an estimated 3,738 Jones County customers per findenergy.com, including about 5.80% of Anamosa and scattered rural addresses elsewhere in the county. Credits solar production under an avoided-cost model — buying back excess production in real time at a rate tied to its power supplier’s costs, with no fixed public $/kWh figure and no month-to-month credit carryover.
Cascade Electric Utility
The smallest of the three, this is the municipal electric utility for the city of Cascade (mostly in neighboring Dubuque County), serving an estimated 343 customers countywide per findenergy.com — almost certainly concentrated in and immediately around the small slice of Cascade that falls inside Jones County’s borders. We haven’t found a published net-metering or interconnection tariff for this utility.
We haven’t found a published utility assignment covering every rural crossroads in Jones County — for any address near a utility boundary, SolQ confirms your exact provider and crediting terms before you sign anything.
Real SolQ Installs in Jones County
We’ll be upfront about where our completed-project records actually stand in Jones County: SolQ has 8 completed residential installs in Anamosa (4.4–13.5 kW, on streets including North Ford Street, South Main Street, Hamilton Court, South Oak Street, East 4th Street, and Knoll Street) and 6 completed installs in Monticello (6.0–19.2 kW, on streets including East South Street, Monterey Trail, North Maple Street, East 3rd Street, County Road D62, and Songbird Drive). Our records also show real installs in two of the county’s smaller communities: 3 completed installs in Wyoming (Alliant Energy accounts, on County Road X75, West Jones Street, and East Jones Street) and 4 completed installs in Oxford Junction (Alliant Energy, on Broadway Street, Fairview Street, and 4th Avenue South). That’s 21 real, completed residential installs across Jones County so far — we don’t have anything on record yet in Olin, Onslow, Martelle, Morley, or the Jones County side of Cascade, and we say so directly rather than implying otherwise. What backs every Jones County project is the same track record behind our 1,179 completed Iowa installs statewide, including dense, proof-backed clusters an hour or so away in Cedar Rapids (109 installs) and Dubuque (83 installs).
Why Jones County Homeowners Choose SolQ
Three Utilities, Handled Correctly
Most solar installers treat a county as one utility territory. Jones County genuinely isn’t — we confirm whether your address is Alliant, Maquoketa Valley Electric, or Cascade Electric before we ever design a system.
Municipality-Aware Permitting
Anamosa and Monticello each run their own permitting process, and Jones County itself handles unincorporated areas and the smaller towns. We manage that paperwork per address, not per county.
Real Iowa Track Record
1,179 completed Iowa installs and counting, a 4.8-star Google rating across 413 reviews, an A+ BBB rating, and EnergySage’s 2026 Local Installer of the Year award — not just marketing copy, but a track record you can verify.
Iowa Solar Tax Benefits
Iowa’s state income-tax credit for residential solar isn’t available for systems installed after 2021. Here’s what Jones County homeowners can actually count on today.
5-Year Property-Tax Exemption
The added home value from your solar system is exempt from property tax assessment for five years after installation.
Sales-Tax Exemption
Qualifying solar equipment is exempt from Iowa sales tax. Labor is still taxable, so we break out real numbers up front.
Utility-Specific Crediting
Alliant’s Rate IO / Rate NM tariffs and Maquoketa Valley Electric’s avoided-cost model both credit solar exports differently — we confirm which applies to your exact address.
Jones County Solar FAQ
Does SolQ serve all of Jones County, or just Anamosa and Monticello?
All of it. Anamosa and Monticello are our two largest, most established Jones County markets, with the most completed installs, but SolQ installs residential solar throughout the county — Olin, Wyoming, Oxford Junction, Martelle, Onslow, Morley, and the Jones County side of Cascade included. This page exists specifically to cover the whole county, not just the biggest two cities.
What if my town isn’t listed here by name?
If you live anywhere inside Jones County’s borders, we almost certainly serve you. We named every incorporated Jones County community we could confirm on this page, but unincorporated addresses and rural routes are covered too. Reach out and we’ll confirm coverage, utility, and crediting terms for your specific address before you commit to anything.
Does SolQ have a dedicated page for Cascade?
Not yet, and likely not soon. Cascade is a real community of roughly 2,386 residents, but it sits primarily in neighboring Dubuque County, with only a small slice crossing into north-central Jones County, and its population sits below the 2,500-resident threshold this site uses for a dedicated city page. We do install in Cascade, on either side of the county line — we just cover it through this Jones County page and our broader Dubuque-market coverage rather than a standalone page.
Is Anamosa or Monticello the Jones County seat?
Anamosa is the Jones County seat, and it’s also the county’s largest city. Monticello, about 9 miles east, is the county’s second-largest city, but it is not the seat.
What electric utility serves my home in Jones County?
It depends on where you are. Alliant Energy serves 100% of Monticello, Martelle, Morley, Olin, Onslow, Oxford Junction, and Wyoming, plus about 94.20% of Anamosa. Maquoketa Valley Electric Cooperative, headquartered in Anamosa, serves the remaining share of Anamosa (about 5.80%) plus scattered rural addresses. Cascade Electric Utility, the municipal utility based in neighboring Dubuque County’s Cascade, serves a small number of customers on the Jones County side of that town. We confirm your exact provider before designing your system.
How does Alliant Energy credit solar production in Jones County?
Alliant credits solar production one of two ways depending on your account: its standard inflow-outflow tariff (Rate IO), which values energy you send to the grid separately from what you use, or a legacy net-metering tariff (Rate NM) for accounts that already had it. Our dedicated Alliant Energy solar page walks through the full detail.
How does Maquoketa Valley Electric Cooperative credit solar production?
Maquoketa Valley Electric Cooperative uses an avoided-cost model rather than a published net-metering tariff: it buys back your excess production in real time at a rate tied to its power supplier’s costs, with monthly credits that don’t carry over and no single published $/kWh figure we can quote for every home. We check the exact terms for your account before you sign anything.
Is Iowa’s state solar tax credit still available?
No. Iowa’s state income-tax credit for residential solar isn’t available for systems installed after 2021. Two state benefits still apply regardless: a 5-year property-tax exemption on the added home value from your system, and a sales-tax exemption on qualifying solar equipment (labor is still taxable).
What about the federal solar tax credit?
If you’re buying your system outright through cash or a loan, the federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act signed in July 2025. If you go with a Lease or PPA instead, the benefit is still built in indirectly: our financing partner owns the system and claims a separate federal credit for commercial-owned solar (Section 48E, active for projects with construction commencing by July 4, 2026, or placed in service by December 31, 2027), which is part of how they can offer $0-down payments below what you’re currently paying your utility. We’ll walk you through exactly what applies to you during your free consultation.
Are there Jones County-specific permitting requirements?
Yes, and they vary by municipality within the county. Anamosa and Monticello each run their own permitting process, separate from Jones County’s own rules for unincorporated areas and the smaller towns. We handle the paperwork with your specific city or the county, and file the interconnection application with your utility, so you don’t have to sort out which office to call.
Has SolQ actually completed solar installs in Jones County?
Yes — 21 completed residential installs on record across Jones County: 8 in Anamosa, 6 in Monticello, 4 in Oxford Junction, and 3 in Wyoming. We don’t yet have a completed install specifically inside Olin, Onslow, Martelle, Morley, or the Jones County side of Cascade, and we say so directly rather than implying otherwise. What backs every Jones County project is the same track record behind our 1,179 completed Iowa installs statewide, including dense clusters in Cedar Rapids and Dubuque.
How does snow affect solar production in an Iowa winter?
Jones County sees real winter weather, and panels are engineered for that seasonal range: steep-mount racking sheds snow faster than a roof’s own pitch, and panels typically clear themselves within a day or two of a storm as they warm in the sun. Production dips in December and January and climbs sharply in spring and summer, which your system design accounts for from the start.
How long does a Jones County solar installation take, start to finish?
Many projects are installed in as soon as 30 days. Some take longer, up to 2-3 months, depending on your municipality’s permitting timeline and your utility’s interconnection queue — Anamosa’s process, for example, moves differently than a smaller town like Olin or Onslow. We give you a realistic timeline for your specific address up front.
Do Anamosa and Monticello offer the same financing options?
Yes. SolQ offers the same cash, loan, and $0-down Lease/PPA options everywhere in Jones County, whether you’re in Anamosa, Monticello, or a smaller town like Olin or Wyoming. What changes by address is which utility credits your production and which municipality handles your permit — not which financing options are on the table.
Built for Jones County
Whether you’re in Anamosa, Monticello, or a smaller Jones County town like Olin or Wyoming, SolQ designs your system around your actual roof, your actual utility, and Iowa’s actual winters — not a generic template.
