Peoria's price band
Peoria is pricier than 72% of the 195 US metros we price for solar panel work.
Solar in Peoria starts near $18,650 for 8 kW, sits at $22,800 for a typical job and reaches $29,400 on hard roofs or with high-end gear. A battery added at the same time is $9,100–$18,700 more.
Peoria is a smaller market with fewer solar installers to choose from. Illinois averages about 4.5 peak sun hours a day in NREL data (the US average is about 5). Illinois has no state solar tax credit; the Illinois Shines program pays upfront for the system's renewable energy credits.
Prices are before incentives. The federal homeowner credit is gone for 2026 installs (it ended for expenditures after December 31, 2025), so any help now comes from your state, your utility or a lease company's own business credit.

Figures cover the Peoria metro area. Jobs in Downtown & the Warehouse District can run higher; simple roofs in East Peoria, Pekin & Morton sit closer to the low end.
Solar panel prices across Peoria
The panels cost the same across Peoria; the roofs do not. Flat and older roofs in Downtown & the Warehouse District push labor up, and big simple roofs in East Peoria, Pekin & Morton keep it down.
Downtown & the Warehouse District
- 8 kW installed
- $19,750–$31,750 installed
- Typical job
- $15,600–$38,600 / 6–10 kW system
Dense blocks with row houses, shared walls and small roofs. Expect fewer panels than the roof size suggests, a crane or extra crew on some jobs, and parking folded into the labor line.
South Peoria & East Bluff
- 8 kW installed
- $19,200–$30,600 installed
- Typical job
- $15,150–$37,200 / 6–10 kW system
Older roofs and older wiring. The system price is standard; the roof repair, panel work and tree trimming decide the final number.
North Peoria & Bradley
- 8 kW installed
- $18,450–$28,800 installed
- Typical job
- $14,550–$35,050 / 6–10 kW system

East Peoria, Pekin & Morton
- 8 kW installed
- $18,300–$29,400 installed
- Typical job
- $14,400–$35,750 / 6–10 kW system

Real solar jobs in Peoria
Here's what common solar panel jobs cost in Peoria in 2026, installed, before incentives.
Smaller home: 6 kW, standard panels
About 22 kWh on an average day at Illinois's sun levels. Smaller systems cost more per kW, about $3,000 here against $2,850 for 8 kW.
Typical home: 8 kW, standard panels
About 29 kWh a day and 10,500 kWh a year. $22,800 is the typical Peoria price for a pitched shingle roof in good shape.
Solar plus a Powerwall 3
An 8 kW system with a 13.5 kWh battery for outages and evening use. Doing both in one job shares the crew, the permit and the utility paperwork.
Big home or EV owner: 10 kW, premium panels
Premium panels make more power per square foot, which helps on small or shaded roofs. Standard panels at 10 kW are $22,700–$35,750.
Re-roof with solar already on it
Taking about 20 panels off and putting them back after the roofers leave, on top of the roof itself. If your roof has less than 10 years left, replace it before solar goes on.
How much do solar panels cost in Peoria?
Between $18,650 and $29,400 for an 8 kW system, installed, and most Peoria homeowners pay close to $22,800. Three things set the number: system size, panel brand and the roof. A simple shingle roof with standard panels lands near the low end; premium panels on a steep or tile roof can pass $36,800.
There is no federal credit to take off these numbers any more. What still cuts the bill in Peoria is a second or third quote, the right system size for your actual use, and any state or utility program. Figures re-verified against 42 sources in November 2026.
Solar prices in Peoria (2026): the lines on a quote
An 8 kW system is $18,650–$29,400 installed, a battery adds $9,100–$18,700, and a panel upgrade adds $1,500–$4,550 if your panel is full.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| 8 kW system, standard panels | $18,650 | $22,800 | $29,400 |
| 8 kW system, premium panels | $20,550 | $26,200 | $36,800 |
| Tesla Powerwall 3, added at install | $11,600 | $14,900 | $18,700 |
| Main panel upgrade (to 200 amps) | $1,500 | $2,550 | $4,550 |
| Tile roof, extra | $1,000 | $1,800 | $2,550 |
| Ground mount, extra | $4,050 | $6,600 | $10,200 |
| Critter guard | $710 | $1,200 | $1,750 |
| String inverter replacement (later) | $1,500 | $2,300 | $3,550 |
The panels are the most visible line, but not where Peoria quotes differ most. Compare the inverter type, the warranty, and whether roof work, a panel upgrade and permits are in the price.
What moves a solar quote in Peoria:
- System size — bigger systems cost less per kW: about $3,000 at 6 kW against $2,750 at 10 kW.
- Panel and inverter brand — premium panels run 10–25% more; microinverters cost more than one string inverter but last longer.
- The roof — tile adds $1,000–$2,550, a ground mount $4,050–$10,200, and a worn roof should be replaced first.
- The electrical panel — a full or 100-amp panel can add $1,500–$4,550 for an upgrade.
- Who sells it — sales and marketing are about 15% of a typical price; local installers often quote less than national brands.
Ask every Peoria installer for the same five things: system size in kW, panel and inverter models, the price per kW, the warranty terms, and what roof, panel and permit work is included. Compare those lines, not the total. Get a quote for your solar install →
Solar Panel Cost in Peoria by System Size
A 6 kW system is $14,700–$23,100, 8 kW is $18,650–$29,400, and 10 kW is $22,700–$35,750, installed with standard panels, before any state or utility incentive.
Worked example: a Peoria home using about 880 kWh a month gets an 8 kW system at $22,800. If the panel is 100 amps, add an upgrade at $2,550 for $25,350. Add a Powerwall 3 in the same job and the total is about $39,500.
A larger home with central AC or an EV may need 10–12 kW: $27,700 for 10 kW, or $34,100 for 12–13 kW at typical prices. Premium panels on 10 kW run $25,000–$44,700.
Peoria Solar Panel Costs by System Size
| System size | Cost | Best for |
|---|---|---|
| 4 kW system — about 14 kWh a day | $10,900–$17,150 installed | Small home or condo; low bills or a small roof |
| 6 kW system — about 22 kWh a day | $14,700–$23,100 installed | Smaller home or modest power use |
| 8 kW system — about 29 kWh a day | $18,650–$29,400 installed | Typical home; about 880 kWh a month of use |
| 10 kW system — about 36 kWh a day | $22,700–$35,750 installed | Larger home, central AC or one EV |
| 12 kW system — about 43 kWh a day | $27,000–$42,550 installed | Big home, pool or electric heat |
| 15 kW system — about 54 kWh a day | $32,600–$51,300 installed | Very large all-electric home or two EVs |
| 8 kW solar + 13.5 kWh battery | $29,650–$47,150 installed | Backup in outages and evening use where exports earn little |
| 13.5 kWh battery only (no solar) | $11,600–$18,700 installed | Backup without panels; shaded roofs |
Hardware vs everything else: where a Peoria solar quote goes
Panels, inverter, racking and wiring are only about 41% of a typical US solar price. On a $22,800 Peoria job that is roughly $9,350. Sales and marketing take about 15%, design, paperwork and overhead about 20%, installer profit about 16%, and the install labor itself only about 6%.
That is why the payback math matters more than the panel brand. An 8 kW system here makes about 10,500 kWh a year. At Illinois's 2024 average of 12.2 cents a kWh across all customers (EIA; home rates usually run higher), that power is worth about $1,300 a year, a simple payback near 18 years. That assumes your utility credits exports at the full rate; lower export credits stretch it, and higher home rates shorten it.
What's included in a Peoria solar quote (and what costs extra)
A standard quote covers the panels, inverter, racking, wiring, the install crew, permits, inspection and the utility hookup paperwork. The headline price often leaves out:
- Roof work — repairs, or $1,000–$2,550 extra for a tile roof
- Panel upgrade — $1,500–$4,550 if your electrical panel is full or 100 amps
- Critter guard — $710–$1,750 to keep birds and squirrels out from under the panels
- A battery — $9,100–$18,700 for 10–13.5 kWh of storage, if you want backup

Your local market
Peoria is a smaller market with fewer solar installers to choose from. The hardware price is national; labor, permits, sales costs and how many installers compete for the job are local.
System size
An 8 kW system is $18,650–$29,400. A 6 kW system is $14,700–$23,100 and 10 kW $22,700–$35,750; the price per kW drops as the system grows.
Panels and inverters
Premium panels add 10–25% ($20,550–$36,800 for 8 kW). Microinverters cost more upfront than one string inverter but usually carry 20–25 year warranties; a string inverter often needs replacing once ($1,500–$3,550).
Your roof
Clay or concrete tile adds $1,000–$2,550, a ground mount $4,050–$10,200. If the roof has less than about 10 years left, re-roof first: removing and reinstalling panels later costs $3,550–$8,150.
Your electrical panel
A full or 100-amp panel is a common surprise. Upgrading to 200 amps adds $1,500–$4,550 in Peoria, and it is cheapest done with the solar job.
Adding a battery
A 10–13 kWh battery adds $9,100–$17,200, a Tesla Powerwall 3 $11,600–$18,700. Batteries make the most sense where outages are common or exports earn little.
Permits and the utility in Peoria
Permits and inspections are about 3% of a typical price, and the utility must approve the hookup before you can switch on. Ask who files the paperwork; a good installer does all of it.
- Get three quotes.Same panels, different sales costs. Peoria quotes for 8 kW run $18,650–$29,400; a second and third bid is the fastest way to find the padding.
- Compare the price per kW.Divide each quote by its size in kW. About $2,350–$2,850 per kW is a good Peoria price for standard panels; much above $3,650 needs a reason.
- Size it to your bills, not your roof.Use 12 months of bills. A system that makes more than you use only pays off if your utility credits exports well.
- Fix the roof first.Re-roofing under existing panels means paying $3,550–$8,150 to take them off and put them back.
- Bundle the panel and battery work.A panel upgrade ($1,500–$4,550) or a battery done in the same job shares the permit, the inspection and the utility visit.
- Check state and utility help.Illinois has no state solar tax credit; the Illinois Shines program pays upfront for the system's renewable energy credits. Ask your utility about rebates and how it credits exports before you sign.
Before you pay a deposit to a Peoria solar installer, get these in writing:
- System size in kW and the expected output in kWh a year
- Panel and inverter brand and model
- Price per kW and the total before incentives
- Roof work, tile or ground-mount extras, priced as their own lines
- Any panel upgrade, priced as its own line
- Permit, inspection and utility interconnection, and who files them
- Warranties: panels, inverter, workmanship and roof leaks
- Payment schedule, and what happens if the utility hookup is delayed
How much do solar panels cost in Peoria?
$18,650–$29,400 installed for an 8 kW system, and $22,800 is typical. A 6 kW system is $14,700–$23,100 and 10 kW is $22,700–$35,750, before incentives.
What is the price per kW for solar in Peoria?
About $2,850 per kW for an 8 kW system with standard panels, within $2,350–$3,650. Smaller systems cost more per kW and larger ones less.
Is there still a federal solar tax credit in Peoria?
Not for systems you buy. The 30% Residential Clean Energy Credit ended for expenditures made after December 31, 2025, and the IRS treats the expense as made when installation is complete. Lease and PPA companies may still claim a business credit and pass some of it on in their price.
How much does solar with a battery cost in Peoria?
About $29,650–$47,150 for 8 kW of panels plus a Tesla Powerwall 3. A 10–13 kWh battery from another brand adds $9,100–$17,200 to the solar price.
How long does solar take to pay off in Peoria?
Roughly 18 years for a typical 8 kW system at Illinois's 2024 average power price from EIA (12.2 cents a kWh across all customers), with every kWh worth the full price. That assumes your utility credits exports at the full rate; lower export credits stretch it, and higher home rates shorten it.
How much power will an 8 kW system make in Peoria?
About 29 kWh on an average day, or 10,500 kWh a year, based on about 4.5 peak sun hours a day for Illinois in NREL data.
Do I need a new electrical panel for solar in Peoria?
Not always. Many 200-amp panels take solar as they are. A full or 100-amp panel may need an upgrade, about $1,500–$4,550 here.
What does solar panel cleaning and upkeep cost in Peoria?
Cleaning is $150–$510 a visit and a health check $150–$360. Many roofs never need cleaning; rain does most of it. Budget $1,500–$3,550 for one string inverter replacement over the life of the system.
How much does it cost to remove solar panels for a new roof in Peoria?
$3,550–$8,150 to take about 20 panels off and put them back, on top of the roof itself.
What permits does solar need in Peoria?
A building or electrical permit, an inspection, and the utility's approval to connect. Your installer should file all of it; permits and inspections are about 3% of a typical price.
