Do I Need a Permit for Solar Panels in Aurora, IL?
Aurora has a dedicated Solar In Aurora page on its city website — a signal that the city has engaged meaningfully with residential solar. The city is in ComEd territory with Illinois's net metering framework, a state renewable energy incentive structure that differs from both California and Virginia, and a solar resource (approximately 4.6–4.8 peak sun hours daily) that's the lowest in this guide but still sufficient for solid economics with today's panel efficiencies and the 30% federal ITC.
Aurora solar permit rules — the basics
Aurora's Building & Permits Division processes solar permits through eTRAKiT. The permit application requires: electrical single-line diagram, roof attachment documentation (racking specifications, attachment method, roof material compatibility), module and inverter specifications, rapid shutdown labeling plan, and the 2026 fee schedule fee calculation. Both the building permit and the electrical permit are applied for simultaneously. The city's plan review typically takes 1–2 weeks for a standard residential rooftop system. One final inspection is required after installation.
Aurora publishes a dedicated "Solar In Aurora" page at aurora.il.us — the city has actively supported solar adoption as part of its sustainability initiatives, including membership in the Fox Valley Sustainability Network and participation in Illinois's clean energy transition under the Climate and Equitable Jobs Act (CEJA). The Solar In Aurora page links to the Green Municipal Electric Aggregation Program and provides background on the Illinois solar incentive landscape. This institutional engagement means Aurora's building inspectors are generally familiar with solar installations and the permit process is reasonably smooth for standard systems.
ComEd (Commonwealth Edison / Exelon) serves Aurora. Illinois's net metering law requires ComEd to offer net metering to residential solar customers. Under Illinois's current net metering structure, exported solar energy earns a credit at the full retail rate for systems up to 2,000 kW — comparable to Virginia's retail net metering and substantially better than California's NEM 3.0 avoided-cost structure. Confirm current ComEd net metering terms at comed.com or by calling ComEd at 1-800-334-7661 before finalizing system design — Illinois utility commission proceedings have been active in modifying net metering rules. After the city final inspection passes, the ComEd interconnection application is submitted — ComEd's PTO process takes approximately 4–8 weeks for residential systems.
The Illinois Solar For All program (administered through the Illinois Power Agency under CEJA) provides incentives for qualifying low-income households and environmental justice communities to access rooftop solar. Aurora's diverse communities include neighborhoods that may qualify for enhanced Solar For All incentives. Visit energizeillinois.com to check eligibility. The 30% federal ITC (IRC § 25D) applies regardless of Solar For All participation. Illinois also provides a property tax exemption for solar installations under the Illinois Property Tax Code — solar systems installed on residential properties are exempt from increased assessed value, similar to North Carolina's and California's exemptions.
Three solar scenarios in Aurora, IL
| Variable | How it affects your Aurora solar permit |
|---|---|
| ComEd net metering — retail rate credits | Illinois's net metering law requires ComEd to credit exported solar at the full retail rate. This is substantially better than California's NEM 3.0 (avoided-cost rates of $0.05–$0.10/kWh) and comparable to Virginia's retail net metering. Confirm current ComEd net metering terms at comed.com before finalizing system design — IL utility commission proceedings have been active. ComEd PTO: 4–8 weeks after city final inspection. |
| Illinois Solar For All program | Illinois CEJA created the Solar For All program for low-income and Environmental Justice Community households. Qualifying Aurora homeowners may receive significant additional incentives beyond the 30% federal ITC. Check eligibility at energizeillinois.com. The permit process is standard — the Solar For All incentive is applied for separately through the state program administrator. |
| HCOA for historic district properties | Historic district properties in Aurora require HCOA review before the building permit can be applied for. Illinois lacks the explicit solar access protection laws of California (Civil Code §714) and NC (§22B-20). Contact the Historic Preservation Division at 630-844-3648 to understand the review requirements for your specific property — administrative review (faster) may apply for rear-slope installations not visible from the street. Full commission review (4–6 weeks) may apply for more visible installations. |
| Aurora solar resource — lower than CA, competitive economics | Aurora's solar resource (~4.6–4.8 peak sun hours/day on south-facing surfaces) is the lowest of any city in this guide. However, the 30% federal ITC, ComEd's retail net metering, Illinois's property tax exemption, and potentially Solar For All incentives create an economics package that remains competitive despite the lower resource. An 8 kW system at $22,000 ($15,400 after ITC) generating $1,000–$1,500 in annual ComEd savings yields a 10–15 year payback — longer than California's equivalent but still a positive lifetime return on a 25-year system. |
| NEC 690.12 rapid shutdown | Required under the NEC (adopted in Illinois) for all new residential solar installations. Enphase IQ8 microinverters and SolarEdge DC optimizers inherently comply. The Aurora inspector verifies rapid shutdown labels at the final inspection. Aurora doesn't use SolarAPP+ (Elk Grove's automated permitting platform) — permits go through standard eTRAKiT plan review (1–2 weeks). |
| Illinois property tax exemption for solar | The Illinois Property Tax Code provides a property tax exemption for qualifying solar energy systems. An Aurora solar installation does not increase the home's assessed value during the exemption period. Similar to California's and North Carolina's exemptions. Confirm current exemption status with Kane County or DuPage County Assessor's office (depending on which county your Aurora property is in) before relying on this for financial analysis. |
Solar economics in Aurora under Illinois net metering
Aurora's solar case is built on Illinois's retail net metering and the 30% federal ITC rather than on exceptional solar resource. The Chicago area's ~4.7 peak sun hours per day is the lowest in this guide — but the economics remain positive because of the incentive stack. A standard 8 kW system in Aurora generates approximately 9,500–10,500 kWh per year. At ComEd's residential electricity rates, that generation is worth approximately $1,300–$1,600 in annual bill reduction under retail net metering. With $15,400 net cost after the 30% ITC, the payback is 10–12 years.
For qualifying Aurora households, the Solar For All program can dramatically change the economics — reducing out-of-pocket costs by $10,000–$15,000+ for qualifying low-income and Environmental Justice Community households. Aurora's diverse demographics mean a meaningful portion of homeowners may qualify. Check eligibility at energizeillinois.com before dismissing solar as unaffordable — the program-adjusted economics may be far more compelling than the standard numbers suggest.
What solar costs in Aurora, IL
Aurora solar installation costs track the Chicago suburban market. A standard 8–10 kW roof-mounted system: $22,000–$32,000 installed. After 30% ITC: $15,400–$22,400. After Solar For All (if qualifying): potentially $5,000–$12,000 net. Ground-mounted systems: $26,000–$42,000. Permit fees per the 2026 annually indexed schedule are modest relative to system cost — call (630) 256-3130 for current amounts. ComEd PTO process (4–8 weeks) is the longest timeline element after city inspection.

Common questions about Aurora, IL solar permits
Do I need a permit for solar panels in Aurora, IL?
Yes. Both a building permit and an electrical permit are required for all residential solar installations. Apply through eTRAKiT at aurora.il.us or call (630) 256-3130. Permit fees per the 2026 fee schedule. Plan review: 1–2 weeks. One final inspection required before ComEd interconnection. Historic district properties require HCOA from the Historic Preservation Division (630-844-3648) before the permit application.
What is Illinois Solar For All and do I qualify in Aurora?
Illinois Solar For All is a state program providing significant additional incentives for qualifying low-income and Environmental Justice Community households to access rooftop solar. Qualifying Aurora homeowners may receive $10,000–$15,000+ in additional incentives beyond the 30% federal ITC. Check eligibility at energizeillinois.com. The permit process is standard regardless of Solar For All participation — the program incentive is applied for through the state administrator separately.
How does ComEd net metering work for Aurora solar customers?
Illinois's net metering law requires ComEd to credit exported solar at the full retail rate for qualifying residential systems. Confirm current terms at comed.com or call 1-800-334-7661 before finalizing system design. After the Aurora city final inspection passes, the ComEd interconnection application is submitted — PTO takes approximately 4–8 weeks. During this period, panels are installed but not yet energized.
Does my Aurora historic district property need special approval for solar?
Yes. Contact the Historic Preservation Division at 630-844-3648 before the permit application. Illinois lacks California's Civil Code §714 or NC's §22B-20 solar access protections. HCOA review requirements vary by property and installation visibility. Rear-slope installations not visible from the street may qualify for faster administrative review. Allow 2–6 weeks depending on the review pathway.
Does Illinois have a property tax exemption for solar in Aurora?
Yes. The Illinois Property Tax Code exempts qualifying solar systems from increased property tax assessment. An Aurora solar installation doesn't increase the home's assessed value during the exemption period. Confirm current exemption status with the Kane County or DuPage County Assessor's office (depending on which county your Aurora property is in). The 30% federal ITC (IRC §25D) is a separate reliable incentive.
Is Aurora's solar resource adequate for a good solar investment?
Yes, despite being the lowest in this guide (~4.7 peak sun hours/day vs. 5.5+ for California cities). The 30% federal ITC, ComEd's retail net metering, Illinois property tax exemption, and potentially Solar For All incentives create competitive economics even with lower resource. Standard 8 kW system payback: 10–14 years. For qualifying Solar For All households, net cost can drop dramatically — payback of 3–8 years is possible with program incentives.
