Jasper County at a Glance
Jasper County was organized in 1846, the same year Iowa was admitted to the Union, and was named for Sergeant William Jasper, a Revolutionary War hero killed at the 1779 Siege of Savannah. The county covers roughly 730 square miles of land in central Iowa, bordered by Marshall County to the north, Story County to the northwest, Polk County to the west, Marion County to the south, Mahaska County to the southeast, and Poweshiek County to the east. An estimated 38,153 residents called Jasper County home as of the 2025 estimate, up modestly from 37,813 at the 2020 Census.
Newton has served as the county seat since the county’s founding, and for much of the 20th century it was best known as the corporate home of the Maytag Company, the washing-machine manufacturer that renamed its Newton corporate address “One Dependability Square.” That era ended when Whirlpool completed its acquisition of Maytag on April 1, 2006, and by late 2007 had closed the former Maytag headquarters office and Newton manufacturing plant, moving brand administration to Whirlpool’s Benton Harbor, Michigan headquarters. Today, part of the historic Maytag campus is occupied by TPI Composites, which manufactures wind-turbine blades in Newton, alongside Iowa Speedway and Des Moines Area Community College’s (DMACC) Newton campus. We mention Maytag’s history because it’s genuinely part of Newton’s story — not because it’s still the town’s major employer today, which it hasn’t been for close to two decades.
Cities We Serve in Jasper County
Newton, the county seat, already has its own dedicated SolQ page with local pricing, utility, and permitting detail. Tap through below, or keep reading — this page exists specifically to give you the countywide overview, including the smaller Jasper County communities that don’t yet have their own page.
Electric Utilities Serving Jasper County
Jasper County genuinely splits between two major providers, not one. Per findenergy.com’s utility-territory data, four real providers serve homes across the county.
MidAmerican Energy
MidAmerican Energy is the numerically largest electricity provider in Jasper County, with an estimated 21,350 county customers per findenergy.com. MidAmerican’s Jasper County footprint runs heaviest in the western part of the county, closer to the Des Moines metro.
Alliant Energy
Alliant Energy is the second-largest provider by county-wide customer count, with an estimated 16,281 customers per findenergy.com, but it’s the dominant utility in Newton itself, plus the nearby communities of Kellogg, Baxter, and Colfax. Full detail on our dedicated Alliant Energy solar page.
Smaller Cooperative Providers
Two smaller providers round out the county per findenergy.com: Consumers Energy Iowa (about 1,138 customers) and Pella Cooperative Electric (about 1,040 customers), the latter reaching the county’s eastern edge toward Pella. Each sets its own crediting structure for solar exports, separate from MidAmerican’s and Alliant’s tariffs.
Which Provider Serves You?
If you’re inside Newton, Kellogg, Baxter, or Colfax, you’re likely on Alliant Energy. Closer to the county’s western edge toward Prairie City and Monroe, MidAmerican Energy is more common. Near the eastern edge toward Pella, check for Pella Cooperative Electric or Consumers Energy Iowa. SolQ confirms your exact provider before designing your system, not after.
The customer counts above come from findenergy.com’s county-level utility-territory data. Because Jasper County is genuinely split between two major providers, SolQ confirms which one actually serves your home before you sign anything.
Real SolQ Installs in Jasper County
SolQ has completed 27 residential installs inside Jasper County: Newton (21) and Sully (6). In Newton, system sizes have ranged 3.5–15.3 kW (median 6.3 kW, roughly 155 kW installed total), mostly on Alliant Energy accounts, on streets including South 11th Avenue West (a 15.3 kW system), North 7th Avenue Place East (9.4 kW), East 20th Street South (7.1 kW), South 5th Avenue East (5.8 kW), and East 10th Street South (4.0 kW). In Sully, systems have ranged 4.5–19.4 kW (median 12.7 kW, roughly 71 kW total), mostly on Alliant Energy accounts, on streets including 9th Avenue, 6th Street, 10th Avenue, and 4th Street. Combined, that’s roughly 226 kW of completed residential solar across the county. We haven’t yet completed installs in Colfax, Prairie City, Baxter, Monroe, Kellogg, Lynnville, Mingo, or Reasnor on record as of this writing — we say so plainly rather than implying a footprint we don’t have there yet, and we’d welcome the chance to change that.
Why Jasper County Homeowners Choose SolQ
A Real Local Footprint
27 completed installs across Newton and Sully, with real streets and system sizes on record — not a county we’re just getting started in.
Two Major Utilities, Confirmed Not Assumed
MidAmerican Energy and Alliant Energy split most of the county between them, with two smaller cooperatives reaching the edges. We confirm your exact provider before designing your system.
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.
Iowa Solar Tax Benefits
Iowa’s state income-tax credit for residential solar isn’t available for systems installed after 2021. Here’s what Jasper 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 and Alliant’s tariffs, plus the co-op crediting rules at Consumers Energy Iowa and Pella Cooperative Electric, all credit solar exports differently — we confirm which applies to your exact address.
Jasper County Solar FAQ
Does SolQ serve all of Jasper County, or just Newton?
Yes — all of it. Newton is our most established market in the county and the county seat, but SolQ installs residential solar throughout Jasper County: Newton, Sully, and the smaller communities and rural addresses in between. This page exists specifically to cover the whole county in one place, not just the biggest city.
What if my town isn’t listed here by name?
If you live anywhere inside Jasper County’s borders, we almost certainly serve you. That includes smaller incorporated communities like Colfax (pop. 2,255), Monroe (pop. 1,967, split between Jasper and Marion counties), Prairie City (pop. 1,700), Baxter (pop. 962), Sully (pop. 881), Kellogg (pop. 606), Lynnville (pop. 380), Mingo (pop. 302), and Reasnor (pop. 152), plus the rural stretches of the county. 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 Newton?
Yes — Newton 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 Newton page applies to you, or if you live elsewhere in Jasper County.
What electric utility serves my home in Jasper County?
It depends where in the county you are. Per findenergy.com, MidAmerican Energy is the numerically largest provider county-wide with an estimated 21,350 customers, running heaviest toward the western part of the county closer to the Des Moines metro. Alliant Energy has an estimated 16,281 county customers and is the dominant utility in Newton itself, plus Kellogg, Baxter, and Colfax. Consumers Energy Iowa (about 1,138 customers) and Pella Cooperative Electric (about 1,040 customers) reach smaller slices of the county. We confirm your exact provider before designing your system.
How does Alliant Energy credit my solar production?
Alliant credits solar production through its inflow-outflow billing structure: power you draw from the grid (inflow) is billed at your normal rate, and power you export (outflow) is credited separately at Alliant’s approved energy credit rate. SolQ checks the exact terms on your account before you sign anything. Full detail is on our dedicated Alliant Energy solar page.
What about MidAmerican Energy customers in Jasper County?
MidAmerican Energy is the largest single provider by customer count in Jasper County and has its own net metering and interconnection rules, separate from Alliant’s tariff. If you’re on MidAmerican, likely toward Prairie City, Monroe, or the county’s western edge, SolQ verifies your exact rate structure and export crediting terms before you sign anything.
What about Consumers Energy Iowa and Pella Cooperative Electric?
These are two smaller providers that reach limited slices of Jasper County, each with its own crediting structure for solar exports, separate from MidAmerican’s and Alliant’s investor-owned tariffs. We check which utility and rate structure applies to your account and explain exactly what it means for your savings 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 Jasper County-specific permitting requirements?
Yes, and they vary by municipality. Newton and each smaller Jasper County city run their own permitting process, separate from the 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 Jasper 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 — Newton can move differently than a smaller community like Sully or Colfax. We give you a realistic timeline for your specific address up front.
Has SolQ actually completed solar installs in Jasper County?
Yes — 27 completed residential installs on record: 21 in Newton and 6 in Sully, ranging from 3.5 to 19.4 kW in system size, mostly on Alliant Energy accounts. That’s a real, verified local footprint backed by the same track record behind our 1,179 completed Iowa installs statewide.
What was Maytag’s connection to Newton, and does it matter for solar?
Maytag Corporation was headquartered in Newton for generations, until Whirlpool completed its acquisition of Maytag in April 2006 and closed the Newton headquarters office and manufacturing plant by late 2007. That history doesn’t change the electrical engineering, but it does mean Newton has a mix of older homes built during the Maytag era alongside newer construction — including on part of the old Maytag campus, now home to TPI Composites’ wind-turbine-blade plant. It’s a mix of roof types SolQ’s local crews have already worked on across our 21 completed Newton installs.
Built for Jasper County
Whether you’re in Newton, Sully, or a smaller Jasper County community, SolQ designs your system around your actual roof, your actual utility, and Iowa’s actual winters — not a generic template.
