Answer
To hire a solar contractor in Chicago, check that the company is certified by the Illinois Commerce Commission as a distributed generation installer, that a Chicago-licensed electrical contractor is named on the permit, and that it can explain the Express Permit Program for rooftop systems up to 13.44 kW. For new ComEd customers since January 1, 2025, export credits offset supply charges only.
Chicago homeowners looking at solar in 2026 face a changed market. The federal homeowner tax credit has ended, ComEd now credits new customers’ exports against supply charges only, and the city has a faster permit path for small rooftop systems. The right contractor is the one who can show they understand all three.
This guide is for homeowners and small-business owners who are ready to compare contractors. It focuses on local rules and the checks that separate a smooth installation from a delayed one.

Latest Updates: Chicago Solar in 2026
Three changes shape the Chicago market more than any equipment upgrade.
| Change | Status | What it means for homeowners |
|---|---|---|
| Federal homeowner credit | Ended | The IRS says the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025 |
| ComEd net metering | New rules for interconnections from January 1, 2025 | Credits offset the Supply section of the bill, not Delivery or Taxes and Fees |
| Chicago Express Permit Program | Active | Rooftop PV up to 13.44 kW and storage up to 20 kWh (10 kWh for non-lithium-ion) use the express path |
Sources: the IRS Residential Clean Energy Credit page, the ComEd net metering FAQ and the City of Chicago’s Express Permit terms for small-scale solar PV.
The federal change is the largest. The ComEd change means system size and self-consumption matter more, because exported energy earns credits against only part of the bill. A contractor who sizes only for annual production, without looking at your hourly usage, can design a system that exports more than it should.
What “Solar Contractor” Means in Chicago
A solar contractor is not just the crew that mounts panels. The term covers the company responsible for design, equipment, permitting, installation, inspection, utility interconnection and activation. Some firms do all of it in-house. Others subcontract roofing or electrical work.
Oversight is split. The state certifies the installer. The city issues the permit and requires a Chicago-licensed electrical contractor on it. ComEd approves interconnection. A good contractor coordinates all three.
Common business models:
- Local EPC contractors handle engineering, procurement and construction under one roof.
- National installers bring brand recognition and standardized financing.
- Sales-only companies sign customers and pass the work to subcontractors. That is not automatically bad, but you should know who will be on your roof.
Required Licenses and Certifications
Check the following before you sign. Where a rule depends on your project, we say so instead of guessing.
Illinois Commerce Commission Installer Certification
Under 83 Ill. Adm. Code 468.30, after December 31, 2013, with the exception of self-installers, all entities that install distributed generation facilities must be certified by the Illinois Commerce Commission before installing in Illinois. The rule is published by the Illinois General Assembly’s administrative code site. Ask for the certificate number and check it with the ICC.
The rule’s definition of a qualified person helps you read an installer’s credentials. It names at least five installations of the relevant technology, or completion of a program such as a NABCEP distributed generation certification, a UL program, a DOL-registered electrician apprenticeship, an ETA program or an approved community-college degree.
Chicago-Licensed Electrical Contractor
The City of Chicago’s Express Permit terms say electrical work must be performed by the Chicago-licensed electrical contractor listed on the permit application, and must comply with the Chicago Electrical Code edition in effect when the application was submitted. Ask for that contractor’s name before work starts.
Structural Review and Roofing
The same city terms say the structural design must be prepared by an Illinois-licensed architect or structural engineer, who must inspect the existing roof structure and electrical system in person before the application is submitted. They also say roofing work must be done under a valid Illinois roofing contractor license where Illinois law requires one.
NABCEP Certification
The North American Board of Certified Energy Practitioners offers installer certifications. The U.S. Department of Energy’s guide to choosing a solar installer calls NABCEP widely recognized as the gold standard among installers, and advises checking that an installer is licensed, bonded and insured and asking for references. NABCEP is a quality signal, not a substitute for the ICC certification.
Insurance
Ask for a certificate of insurance. If the contractor uses subcontractors, ask how their coverage is documented.
Pro Tip
Ask for the ICC certificate number, the name of the Chicago-licensed electrical contractor and a certificate of insurance in one email. A professional contractor can send all three quickly.
How Chicago Permitting Works
Permitting is where many projects stall. The City of Chicago has an Express Permit Program for small rooftop solar and a standard plan review for everything else.
Express Permit Program
Per the city’s terms, solar PV systems permitted through the program are limited to 13.44 kW of output, and energy storage to 20 kWh (10 kWh for non-lithium-ion batteries). Only one installation is allowed per ComEd electrical service connection. The permit covers roof-mounted systems on an existing building. It does not authorize components attached to walls or ground mounted.
Other terms the city lists:
- Solar equipment may not be within 3 feet of the roof edge on a residential building, or 4 feet on a non-residential or mixed-use building
- Primary electrical equipment must be listed and labeled by a nationally recognized testing laboratory
- Equipment must be installed to the manufacturer’s instructions, with a copy on site at inspection
- A permanent label is required where the system includes rapid shutdown
- Deficiencies in the existing electrical system must be corrected before solar equipment is connected
We do not state a permit fee or approval time here. We could not read a current fee schedule from the city page, so ask the Department of Buildings or your contractor for the current fee and review time.
Standard Plan Review
Larger systems, ballasted flat-roof installations and other systems outside the express terms go through standard plan review. Ask your contractor which path applies before you sign.
ComEd Interconnection
After the project is built, the contractor submits the interconnection and net metering paperwork to ComEd. The ComEd FAQ says net metering participation begins after interconnection approval, a signed net metering election and permission to operate. Ask the contractor for a written timeline for each stage, because durations vary by project and queue.
2026 Costs and Incentives in Chicago
Without the federal homeowner credit, your out-of-pocket cost is higher, and state and utility incentives matter more.
Typical System Costs
EnergySage’s Chicago cost page lists Illinois figures, as of November 2026, of $2.93 per watt, an average system size of 11.58 kW and about $33,918 before incentives, with prices from $28,830 to $39,006. The page does not give Chicago-only numbers. We use the Illinois average below as an illustration.
| System size | Pre-incentive cost at $2.93/W | Source basis |
|---|---|---|
| 5 kW | $14,650 | $2.93 per watt multiplied by 5,000 W |
| 8 kW | $23,440 | $2.93 per watt multiplied by 8,000 W |
| 11.58 kW | About $33,918 | EnergySage Illinois average system |
The first two rows are our arithmetic, not quotes. Your price depends on the roof, equipment, labor and scope. Size should follow annual usage, roof space, shading and how much you want to offset under ComEd’s rules.
ComEd Distributed Generation Rebate
The ComEd FAQ says the DG Rebate is $250 or $300 per kW of installed capacity for eligible systems, with a similar rebate for storage. EnergySage lists $300 per kW for solar. If you take the DG Rebate, net metering credits do not expire annually, and a customer with legacy status loses legacy status by electing the rebate for generation.
At $300 per kW, an 8 kW system would earn $2,400. That is arithmetic on the published rate, so confirm your customer class and the current rate with ComEd.
- 5 kW system cost$14,650
- 5 kW at $300/kW rebate$1,500
- 8 kW system cost$23,440
- 8 kW at $300/kW rebate$2,400
- 11.58 kW system cost$33,918
- 11.58 kW at $300/kW rebate$3,474
Source: EnergySage Illinois average of $2.93 per watt; ComEd DG Rebate of up to $300 per kW per ComEd FAQ; rows computed by us, checked November 2026.
Key Takeaway
The rebate covers a fraction of system cost. Compare quotes on the net price after incentives, and ask each contractor to show which incentive rates and billing assumptions they used.
Other Incentives
| Incentive | What EnergySage reports | Who it suits |
|---|---|---|
| Illinois Shines | One upfront payment based on expected renewable energy credits over 15 years, through an approved vendor | Owners of on-site systems |
| Illinois Solar for All | Income-qualified; single-family home at 80% or less of Area Median Income | Income-qualified households |
| ComEd DG Rebate | $300 per kW of solar, per EnergySage | ComEd customers with eligible systems |
Programs and budgets change. Read the program administrators’ own pages before you rely on an amount. We did not verify county-level programs and do not list them.
Payback Under Current Billing Rules
We do not publish a payback range for Chicago, because it depends on your usage pattern, the supply price you pay, system cost and incentives. Ask each contractor to show an hourly or monthly model and the assumptions behind it. If a proposal assumes full retail credit for every exported kilowatt-hour, the payback estimate is wrong for new interconnections.
How ComEd’s Net Metering Changes Affect Your Design
The ComEd FAQ says that as of January 1, 2025, new net metering customers receive credits that offset charges in the Supply section of the bill. Customers with legacy status receive credits that offset Supply, Delivery and Taxes and Fees. The FAQ says legacy status requires the system to have received permission to operate before January 1, 2025.
This shifts design priorities:
- Self-consumption matters more. Energy used on site avoids the whole bill, while exported energy earns credits against only the Supply section.
- Oversizing is less valuable. Extra production earns less than before.
- Storage becomes worth modeling. A battery lets you shift midday solar to the evening.
- Load shifting helps. Running dishwashers, dryers and EV chargers during sunny hours improves the economics.
A contractor who divides your annual usage by a production factor is using older logic. Ask whether they modeled your usage against production over the day and the year. Our guide to the solar self-consumption rate calculator explains the idea.
Questions to Ask Every Solar Contractor
Use this list in your first conversation. The answers show whether you are talking to a local expert or a sales script.
- Who holds the ICC certification for my project?
- Who is the Chicago-licensed electrical contractor on the permit?
- Which permit path will my project use, express or standard review?
- Do you use in-house crews or subcontractors for roof and electrical work?
- What equipment do you recommend, and why?
- What does the workmanship warranty cover?
- How do you handle the ComEd interconnection process?
- What is the timeline for each stage, in writing?
- How did you size my system, and what usage did you assume?
- What happens if my roof needs repairs before or during installation?
- Which incentives did you include, and when do they change?
- What is the total all-in price, and what could change it?
Listen for specifics. Vague answers such as “we handle everything” are red flags.
Red Flags That Should Make You Walk Away
- Pressure to sign today. The FTC’s solar consumer guide warns against companies that pressure you for a quick decision or want you to sign without time to review.
- No ICC installer certification. The state rule requires it for most installers.
- No clear answer on who pulls the electrical permit.
- No proof of insurance.
- Guaranteed production without a site visit. A satellite estimate is a starting point.
- Asking for full payment upfront. Compare payment terms across quotes and read the contract.
- Promising the federal homeowner credit for a 2026 install. The IRS says it is not available for property placed in service after December 31, 2025.
- Refusing to put equipment brands in writing.
If a contractor checks more than one box, get another quote.
Local vs National Installers
We do not have a sourced price comparison between local and national installers in Chicago, so compare quotes on scope, equipment, warranty and timeline rather than on a general rule.
Local installers often have the advantage of closer familiarity with Chicago permitting and ComEd paperwork, and a nearby office. National installers may offer standardized financing or lease and PPA products. If you consider a lease or PPA, note the FTC’s warning that you do not own the system, so you cannot claim tax credits that go to the owner.
What a Good Chicago Quote Looks Like
A complete quote should include:
- System size in kilowatts DC and AC
- Estimated annual production in kilowatt-hours, with the assumptions
- Panel and inverter manufacturer and model numbers
- Mounting system and roof penetration plan
- Total pre-incentive price and price per watt
- Incentives applied and how they were calculated
- Financing terms, including APR and any escalator
- Workmanship and equipment warranties
- A written timeline and payment schedule
If items are missing, ask for them.
Show the export-credit assumption in the proposal
Customers compare quotes more easily when each one states its usage, production and incentive assumptions. See how a proposal can carry them from the design model.

Common Mistakes Chicago Homeowners Make
Focusing Only on Price Per Watt
Price per watt compares similar systems, but it ignores equipment quality, warranty and installer experience.
Ignoring the Roof
The city’s terms require an in-person inspection of the roof structure and electrical system before the express application. A contractor who quotes without looking at your roof, attic and panel is guessing.
Signing Before Understanding the Billing Rules
Some homeowners still expect full retail credit. Ask the contractor to show how ComEd’s current rules affect projected savings.
Choosing the First Quote
EnergySage’s page says comparing multiple quotes can lower prices. Compare at least three on the same scope.
Timeline: From Quote to Activation
Stages are fairly consistent even if the durations are not. Ask your contractor for a written estimate for each.
- Site assessment and quote
- Contract signed and financing approved
- Permit submitted and approved, through express or standard review
- Equipment ordered and delivered
- Installation
- City inspection
- ComEd interconnection and meter work
- Permission to operate and activation
Delays usually happen at permitting, equipment delivery or utility interconnection, so ask which stage the contractor has handled most often in Chicago.
Conclusion
Choosing a solar contractor in Chicago is harder than it was two years ago, but the fundamentals are the same. Check the ICC certification and the Chicago-licensed electrician. Compare at least three detailed quotes. Make sure each one reflects the end of the federal homeowner credit and ComEd’s current net metering rules.
Start with three steps:
- Ask for the ICC certificate number and the name of the licensed electrical contractor.
- Request a quote that shows pre-incentive cost, incentives and the billing assumption behind the savings.
- Ask for local references from recent projects.

Frequently Asked Questions
What license does a solar contractor need in Chicago?
A solar installer needs Illinois Commerce Commission distributed generation installer certification, with exceptions for self-installers. Electrical work on a Chicago Express Permit must be done by the Chicago-licensed electrical contractor named on the permit. Roofing work may also need an Illinois roofing contractor license where Illinois law requires it.
How much does a solar contractor charge in Chicago in 2026?
EnergySage lists an Illinois average of $2.93 per watt, about $33,918 before incentives for an 11.58 kW system, with a range of $28,830 to $39,006. It does not give a Chicago-only figure, so compare at least three written quotes for your own roof and usage.
Is the 30% federal solar tax credit still available in 2026?
Not for homeowner-owned systems. The IRS says the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025. Commercial and third-party-owned systems may follow different rules, so ask your tax adviser before assuming either way.
What is Chicago’s Express Permit Program for solar?
It is the city’s faster permit path for small rooftop solar. Per the Department of Buildings, systems are limited to 13.44 kW of output and storage to 20 kWh, with 10 kWh for non-lithium-ion batteries. Ground-mounted and wall-mounted systems are not covered. Ask the city for the current fee.
How has ComEd net metering changed for new solar customers?
As of January 1, 2025, new ComEd net metering customers receive credits that offset charges in the Supply section of the bill. Customers with legacy status, who had permission to operate before that date, receive credits against Supply, Delivery and Taxes and Fees. ComEd’s DG Rebate can change how some credits work.
What questions should I ask a solar contractor before signing?
Ask who holds the ICC certification, who the Chicago-licensed electrician is, whether subcontractors will be used, which equipment is quoted and why, what the workmanship warranty covers, how interconnection with ComEd is handled, and how the quote models export credits under current billing rules.
Are there Illinois solar incentives in 2026?
Yes. EnergySage lists Illinois Shines, which pays an upfront amount based on expected renewable energy credits over 15 years through an approved vendor, plus Illinois Solar for All for income-qualified households. ComEd’s DG Rebate is $250 or $300 per kW depending on customer class.
