What home solar costs in South Jacksonville - and the 2026 rules that changed the math
The solar industry is still quoting like it is 2025, but the 30% federal credit died on December 31, 2025. Here is what a South Jacksonville homeowner actually pays in 2026, what Illinois still offers, and how to compare quotes without getting played.
Installed home solar for South Jacksonville homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - South Jacksonville systems completed in 2026 get $0 from it.
Under Illinois's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
South Jacksonville plus 10 surrounding towns within 40 km form one installer market of about 38,154 people - quotes should not vary much by town.
The single biggest change for South Jacksonville homeowners in 2026: the federal 30% tax credit is gone. A $31,000 system that effectively cost $21,700 in 2025 now costs the full $31,000. That does not automatically make solar a bad buy in Illinois - but it makes the state rules below matter far more.
Door-to-door solar sales in South Jacksonville run on urgency and outdated math. The two facts that defuse most pitches: the U.S. marketplace average is about $2.58 a watt installed, and the federal credit expired for systems finished after December 31, 2025. Any quote built on either being different needs proof.

The 30% federal tax credit is gone for 2026 installations
The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.
Illinois rules that decide your payback
| Rule | Illinois status |
|---|---|
| Export compensation (net metering) | For systems interconnected on or after January 1, 2025, Illinois no longer offers full-retail net metering: exports are credited only at the electricity-supply rate while the customer keeps paying delivery charges on all electricity drawn from the grid, and those customers are also eligible for a one-time distributed-generation "smart inverter" rebate of at least $300/kW (residential) from ComEd, Ameren, or MidAmerican. |
| State incentive | Illinois Shines (Adjustable Block Program) REC payments, Illinois Solar for All for income-eligible households, and the utility Distributed Generation / Smart Inverter Rebate (at least $300/kW residential) |
| Sales tax on the system | Not exempt - taxed like any purchase |
| Property tax on added home value | Excluded |
Customers who had full-retail net metering before January 1, 2025 keep it for the lifetime of the system, so two neighbors can be on very different deals; community solar subscriptions are available only in the ComEd and Ameren service territories.

Why only these platforms
Ask any homeowner whose installer went bankrupt: the money was not lost on the panels, it was lost on the workmanship warranty that evaporated. Before comparing prices, compare survival odds - years in business, local installations you can drive past, and manufacturer-backed workmanship coverage.
Solar lead generation is where most industry abuse lives, so this guide only links platforms that show you multiple named installers and let you walk away - never single-installer funnels or phone-blast forms. If a platform falls below that bar it gets removed from every page on this site.
| Platform | What you get | Background |
|---|---|---|
| EnergySage | Side-by-side bids from multiple installers | The largest U.S. solar marketplace; publishes its pricing data publicly |
| Modernize | Matched with vetted local installers | Established home-services network (QuinStreet); installers are screened |
Getting quotes in South Jacksonville
Same-day contracts are a red flag in this industry. Legitimate IL installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.
- Your last 12 months of electricity bills - sizing should follow real usage
- Roof age and type - reroofing after panels go up is expensive
- Your utility's export rate under Illinois rules - it decides the payback
- Whether you want backup power - that is a battery decision, priced separately
- Written itemization: hardware, labor, permits, and any financing dealer fee
Reading a South Jacksonville roof honestly
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.

Common questions
How do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
