Clarke County at a Glance
Clarke County is home to an estimated 9,600–9,700 residents (9,662 per the 2024 Census Bureau estimate; 9,748 at the 2020 Census). Osceola is both the county’s largest city and its county seat, sitting right where Interstate 35 meets U.S. Highways 34 and 69, about 40 miles south of Des Moines. The county was organized in January 1846 and named for James Clarke, the last Governor of the Iowa Territory before statehood. It covers roughly 431 square miles of south-central Iowa, bordered by Warren County to the northeast, Madison County to the northwest, Union County to the west, Decatur County to the south, and Lucas County to the east.
Clarke County is genuinely a one-city county for SolQ’s purposes: Osceola is the only incorporated community that clears Iowa’s 2,500-resident threshold for its own dedicated page. That doesn’t mean it’s the only place we install — Murray, Woodburn, Weldon, and the farmsteads and rural routes around them are all part of the same market, on the same two utilities, with the same tax rules. Osceola’s own economy runs on manufacturing (Altec’s Osceola Body Plant, Osceola Foods, SIMCO Drilling Equipment, Miller Products Company), healthcare (Clarke County Hospital), and tourism (the Lakeside Hotel Casino on West Lake), alongside the row-crop and livestock agriculture that dominates the rest of the county — a mix that means real variation in roof types and electric loads even in a fairly small county.
Cities & Towns We Serve in Clarke County
Osceola is Clarke County’s only city large enough for its own dedicated SolQ page, with local pricing, utility, and permitting detail. Tap below for the full picture — or keep reading, since this page exists specifically to cover the rest of the county in one place.
Also Serving Clarke County’s Smaller Communities
Clarke County has three other incorporated towns that don’t (yet) clear the population threshold for their own dedicated page, but we install there too: Murray (pop. ~580–680, on the Union County line), Woodburn (pop. ~130–150), and Weldon (pop. ~135–140, near the Decatur County line). We also install throughout the unincorporated townships and rural routes that make up most of Clarke County’s land area. If you live in one of these towns, or anywhere else in Clarke County, the FAQ below explains how coverage and utility service work for you.
Electric Utilities Serving Clarke County
Clarke County is served by exactly two electric providers — a genuinely simpler picture than many Iowa counties, but still not a single-provider county, and we say so plainly rather than defaulting to one name.
Alliant Energy
The county’s larger provider by customer count, serving Osceola, Murray, and Woodburn, plus most of the surrounding rural area. Solar production is credited under Alliant’s standard inflow-outflow tariff (Rate IO), with a limited legacy net-metering pilot (Rate NM) still available to customers who already qualify. Full detail on our dedicated Alliant Energy solar page.
Clarke Electric Cooperative
A member-owned cooperative headquartered right in Osceola (1103 North Main Street), serving a share of Osceola itself plus rural stretches of the county — its broader territory actually spans eight Iowa counties (Clarke, Warren, Madison, Union, Lucas, Decatur, Ringgold, and Wayne), not just this one. Clarke Electric does not publish a specific net-metering or interconnection crediting rate in its public materials, so we confirm exact terms with the co-op directly before designing anything.
We haven’t found a separately published utility assignment for Weldon or for every rural address — for those, and for any address near a boundary between the two providers, SolQ confirms your exact provider and crediting terms before you sign anything.
Real SolQ Installs in Clarke County
We’ll be upfront: SolQ doesn’t have a completed residential install on record anywhere in Clarke County yet — not in Osceola, Murray, Woodburn, or Weldon. Clarke County is a newer market for us, and we’re not going to borrow another county’s numbers to make it look otherwise. What we can point to is a real, verified track record close by: 5 completed installs about 25 miles east in Chariton, Lucas County, ranging 6.3–16.2 kW on streets including Iowa Highway 14, North 7th Street, South 2nd Street, and Mallory Drive, all on Alliant Energy’s grid — plus 1,179 completed residential solar installs across Iowa overall, backed by the same install crews, permitting relationships, and equipment lineup behind every one of those projects. As we complete more Clarke County installs, this section will be updated with real, address-level detail, the same way it already is for our established Iowa markets.
Why Clarke County Homeowners Choose SolQ
Two Utilities, Handled Correctly
We confirm whether your address is Alliant Energy or Clarke Electric Cooperative before we ever design a system — not assumed, not guessed.
Municipality-Aware Permitting
Osceola and Clarke County each run their own permitting process. 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 Clarke 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 Energy’s Rate IO/Rate NM and Clarke Electric Cooperative’s unpublished crediting terms differ — we confirm which applies to your exact address.
Clarke County Solar FAQ
Does SolQ serve all of Clarke County, or just Osceola?
All of it. Osceola is our largest, most established Clarke County market, but SolQ installs residential solar throughout the county — Murray, Woodburn, Weldon, and the rural townships and farmsteads in between. This page exists specifically to cover the whole county, not just the county seat.
What if my town isn’t listed here by name?
If you live anywhere inside Clarke County’s borders, we almost certainly serve you. We named every incorporated Clarke County town 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 Osceola too?
Yes — Osceola has its own dedicated SolQ page with city-specific pricing, utility, and permitting detail. This county page is the place to start if you’re not sure whether the Osceola page applies to you, or if you live somewhere smaller.
What electric utility serves my home in Clarke County?
One of two providers. Alliant Energy serves Osceola, Murray, Woodburn, and most of the surrounding rural county. Clarke Electric Cooperative, headquartered in Osceola, serves a share of Osceola itself plus rural stretches of the county as part of a service territory that spans eight Iowa counties. We haven’t found a separately published assignment for Weldon or every rural address, so for those and any address near a boundary, we confirm your exact provider before designing your system.
How does Alliant Energy credit my solar production?
Alliant credits solar customers through its standard inflow-outflow tariff (Rate IO): you’re billed the retail rate for power delivered to your home, and separately credited for power you send to the grid. A limited legacy net-metering pilot (Rate NM) is still available to customers who already qualify. Full detail is on our dedicated Alliant Energy solar page.
How does Clarke Electric Cooperative credit solar production?
Clarke Electric Cooperative doesn’t publish a specific net-metering or interconnection crediting rate in its public materials. As a member-owned cooperative headquartered in Osceola, its terms can differ from an investor-owned utility like Alliant. We confirm exact crediting terms directly with the co-op for your address 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 that begin construction by July 4, 2026 or are 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 Clarke County-specific permitting requirements?
Yes, and they vary by municipality within the county. Osceola runs its own permitting process, separate from Clarke County’s own rules for unincorporated areas. 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.
How long does a Clarke 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 — Clarke Electric Cooperative’s process moves differently than Alliant Energy’s Level 1 interconnection tier. We give you a realistic timeline for your specific address up front.
Has SolQ actually completed solar installs in Clarke County?
Not yet — Clarke County is a newer market for us, and we say so directly rather than implying otherwise. We do have a real, verifiable track record close by: 5 completed installs about 25 miles east in Chariton, Lucas County, plus 1,179 completed installs across Iowa overall. We’ll update this page with real Clarke County project examples as they come in.
How does snow affect solar production in a Clarke County winter?
Panel angle and mounting are designed for snow to shed naturally, so production typically rebounds quickly after storms as panels clear 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.
Do Osceola and the rest of Clarke County get the same financing options?
Yes. SolQ offers the same cash, loan, and $0-down Lease/PPA options everywhere in Clarke County, whether you’re in Osceola or a smaller town like Murray, Woodburn, or Weldon. 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 Clarke County and South-Central Iowa
Whether you’re in Osceola, or a smaller Clarke County town like Murray, Woodburn, or Weldon, SolQ designs your system around your actual roof, your actual utility, and Iowa’s actual winters — not a generic template.
