Butler County at a Glance
Butler County was established on January 15, 1851, and organized in 1854, named for General William Orlando Butler, a Kentucky native and Mexican–American War hero. The county covers roughly 580 square miles of land plus 1.6 square miles of water in north-central Iowa, bordered by eight counties including neighboring Bremer, Black Hawk, and Grundy counties. Allison has served as the county seat since the county’s founding, near the geographic center of the county. Per Wikipedia, Butler County is also the only county in Iowa without a four-lane U.S. highway or interstate, a hospital, or a movie theater — a genuinely rural profile.
Butler County had a 2020 Census population of 14,334, an estimated 14,049 as of July 2025 — a roughly 2% decline, typical of small rural Iowa counties. Ten incorporated cities sit inside the county’s borders, and no single city dominates: Parkersburg (population estimate 1,960) is the largest, but Shell Rock (1,250), Clarksville (1,219), Aplington (1,078), Greene (927), and the county seat of Allison (925) all sit within a few hundred residents of one another. The county is effectively 100% rural — not a single incorporated place here is classified as urban by the Census Bureau. That’s why this page exists: rather than building around one anchor city, SolQ ties the whole county together with real, verified detail for every community, county seat or not.

Also Serving the Farms and Unincorporated Areas In Between
Most of Butler County isn’t inside any city limits — the county is effectively 100% rural, and unincorporated communities like Austinville sit outside the ten incorporated towns. SolQ serves rural acreages and farmsteads the same way we serve Parkersburg or Allison: we confirm your utility, roof, and permitting path before you commit to anything. Butler County also borders Bremer County (home to Waverly), Grundy County, and Black Hawk County (Waterloo and Cedar Falls) — all counties where SolQ already has an established Iowa presence.
Electric Utilities Serving Butler County
Butler County runs on six real electricity providers, per findenergy.com’s county-level data — one investor-owned utility, a countywide cooperative, a municipal utility based in neighboring Cedar Falls, Aplington’s own city-owned utility, and two small cooperative slivers along the county’s edges. We confirm which one actually serves your address first.
MidAmerican Energy
The county’s dominant investor-owned utility, with an estimated 8,706 customers per findenergy.com. Residential rates run about 10.97¢/kWh, average bill near $89/month. MidAmerican customers get Iowa’s statewide net metering at full retail credit, though unused annual credits expire.
Butler County REC
A member-owned cooperative headquartered in the county, serving an estimated 2,168 customers per findenergy.com — the county’s second-largest provider, concentrated in rural areas outside MidAmerican’s footprint. As a cooperative, it isn’t required to offer retail-rate net metering; we confirm its terms first.
Cedar Falls Electric Utility
A municipal utility based in neighboring Cedar Falls reaching an estimated 2,059 customers inside Butler County, per findenergy.com — mostly rural accounts along the southeastern edge, near Shell Rock and New Hartford. Its net metering terms differ from MidAmerican’s; we confirm the exact terms for your address.
Aplington Municipal Electric Utility
Aplington runs its own city-owned electric utility, serving an estimated 580 customers per findenergy.com, almost entirely within town limits. It’s one of a small number of Iowa towns with true municipal electric service, and solar interconnection runs through city hall rather than a state-regulated tariff.
Grundy County REC
Headquartered in neighboring Grundy County, reaching an estimated 54 Butler County customers per findenergy.com — a small rural pocket near the county line.
Franklin REC
Headquartered in neighboring Franklin County, reaching an estimated 45 Butler County customers per findenergy.com — the smallest footprint in the county, along its western edge.
The countywide average residential rate runs about 15.06¢/kWh, with Parkersburg, Shell Rock, and Clarksville ranging roughly 10.7¢ to 16.2¢/kWh depending on provider. These figures describe Butler County as a whole, not any specific address — SolQ confirms your actual provider before designing your system.
Real SolQ Installs
We’ll be straightforward: we don’t yet have a completed install on record inside Butler County’s ten towns, and we’d rather say so than pad the number. What we do have is real, verifiable Iowa proof close by. SolQ has completed 1,179 residential solar installs across Iowa, including 3 in Waterloo, in neighboring Black Hawk County, on a MidAmerican Energy account — the same utility serving most of Butler County. Statewide, roughly 17 verified installs sit on MidAmerican accounts, in cities including Des Moines, Davenport, Waterloo, and Council Bluffs, giving us direct experience with the exact tariff and interconnection process Butler County MidAmerican customers will go through. Every Butler County project is backed by that same crew, equipment, and permitting experience — and if you’re our first Butler County customer, we’ll say so plainly.
Why Butler County Homeowners Choose SolQ
No Town Gets Left Behind
Butler County has no single dominant city — Parkersburg, Shell Rock, Clarksville, Aplington, Greene, and Allison are all within a few hundred residents of each other. We serve every one of them, plus the rural stretches between them, with the same attention.
Six Utilities, One Point of Contact
MidAmerican Energy, Butler County REC, Cedar Falls Electric, Aplington’s municipal utility, and two smaller cooperatives all serve real customers here. We confirm which one serves your address, and its crediting rules, before you sign anything.
Real Iowa Track Record
1,179 completed installs across Iowa, including real MidAmerican Energy proof in neighboring Black Hawk County, a 4.8-star Google rating across 413 reviews, an A+ BBB rating, and EnergySage’s 2026 Local Installer of the Year award.
Iowa Solar Tax Benefits
Iowa’s state income-tax credit for residential solar isn’t available for systems installed after 2021. Here’s what Butler 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
MidAmerican’s net metering tariff and Butler County’s cooperative and municipal utilities each value solar exports differently — we confirm which applies to your exact address.
Butler County Solar FAQ
Does SolQ serve all of Butler County, or just Allison?
All of it. Allison is the county seat, but SolQ installs residential solar throughout Butler County — Parkersburg, Shell Rock, Clarksville, Aplington, Greene, Dumont, New Hartford, Bristow, Aredale, and every rural stretch between. This page exists because the county doesn’t have one dominant city.
Why don’t you have a dedicated page for Parkersburg or Allison yet?
Butler County doesn’t have one dominant city — Parkersburg, Shell Rock, Clarksville, Aplington, Greene, and Allison are all within a few hundred residents of each other. Rather than build around one town, we built one thorough countywide page that treats every community equally. Dedicated city pages may follow as our local install history grows.
What electric utility serves my home in Butler County?
MidAmerican Energy is the dominant provider, with an estimated 8,706 Butler County customers per findenergy.com. Butler County REC serves 2,168, Cedar Falls Electric reaches 2,059 along the southeastern edge, Aplington’s own municipal utility serves about 580, and two small cooperatives, Grundy County REC and Franklin REC, cover pockets near the county’s edges. We confirm your exact provider first.
How does MidAmerican Energy credit my solar production?
MidAmerican customers qualify for Iowa’s statewide net metering at full retail credit for electricity your system sends to the grid. One key difference from some Iowa utilities: MidAmerican’s unused annual credits expire rather than being cashed out, so system sizing matters — something we factor into your design.
What about Butler County REC, Cedar Falls Electric, and the other providers?
Unlike MidAmerican, cooperative and municipal utilities — Butler County REC, Cedar Falls Electric, Aplington’s utility, Grundy County REC, Franklin REC — aren’t required by Iowa law to offer retail-rate net metering. Some credit generously anyway; others use an avoided-cost model. We confirm the exact rules for your provider before you sign anything.
What does solar typically cost, and how much can I save?
Cost depends on your roof, electricity use, and your utility’s crediting rules, so we don’t quote a single countywide number. Butler County’s average residential rate runs about 15.06¢/kWh, on the higher end for the region, which generally means a faster solar payback than in cheaper-power areas. We’ll build a real, address-specific savings estimate during your free consultation.
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 with 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. With a Lease or PPA, the benefit is built in indirectly: our financing partner claims a separate credit for commercial-owned solar (Section 48E, active for projects beginning construction by July 4, 2026, or placed in service by December 31, 2027), helping enable $0-down offers below your current utility bill. We’ll walk you through what applies to you.
What does the installation process look like, start to finish?
We start with a free consultation and an address-specific design. From there we handle permitting with your city or county, schedule the install (typically one day), and file the interconnection application with your utility. Many Butler County projects go live within 30 to 60 days, though timelines vary by municipality and utility queue — Aplington’s municipal process runs differently than MidAmerican’s.
Are there Butler County-specific permitting requirements?
Yes, and they vary by municipality. Butler County’s ten towns each run their own permitting process, separate from the county’s rules for unincorporated and rural properties. Aplington’s also runs through its own municipal utility rather than a state-regulated one. We handle the paperwork and interconnection filing, so you don’t have to sort out which office to call.
Has SolQ actually completed solar installs in Butler County?
Not yet, and we’d rather say so than imply otherwise. We have 1,179 completed residential installs across Iowa, including real installs in Waterloo, neighboring Black Hawk County, and roughly 17 verified installs statewide on MidAmerican Energy accounts — the same utility serving most of Butler County. If you’re our first Butler County customer, you get the same crew and process behind that track record.
Does Butler County’s adjacency to Bremer, Grundy, and Black Hawk counties matter for solar service?
It helps us know the area well, though it doesn’t change how we treat your project. Butler County borders Bremer County (Waverly), Grundy County, and Black Hawk County (Waterloo, Cedar Falls) — all places where SolQ already has an established Iowa presence. Cedar Falls Electric itself reaches into southeastern Butler County. We design your system around your specific roof, usage, and utility.
How does snow affect solar production in an Iowa winter?
Butler County sees real winter weather like the rest of north-central Iowa, and panels are engineered for it: steep-mount racking sheds snow faster than a roof’s pitch, and panels typically clear within a day or two 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.
Built for Butler County
Whether you’re in Parkersburg, Allison, or a smaller Butler County town like Bristow or Aredale, SolQ designs your system around your actual roof, your actual utility, and Iowa’s actual winters — not a generic template.
