Naperville Electricity Prices
If you live in Naperville and have watched your electricity bills climb, you’re not alone. Rising prices are prompting many homeowners to explore solar.
Illinois electricity prices rose about 20% between 2021 and 2024, climbing from 13.2 cents to 15.9 cents per kWh. That’s a real increase Naperville families feel each month.
For many Naperville homeowners, home solar panels offer a way to generate their own power and gain more predictable energy costs, instead of relying entirely on the grid.
Over time, solar can help protect your household budget from future rate increases. As grid prices continue to shift, producing your own electricity offers Naperville families lasting value and greater peace of mind.
Price of Energy: Illinois vs National Average
Naperville Area Utility Providers
If you live in Naperville, your electricity comes from ComEd. Understanding what you pay per kilowatt-hour is a helpful first step toward deciding whether home solar makes sense for your household.
In 2023 (the most recent data available), ComEd’s rate was about 14.8¢ per kWh—below both the Illinois average of 15.70¢ and the national average of 16.0¢, thanks partly to Illinois’ diverse energy mix.
Even at lower-than-average rates, grid prices can shift over time. Producing your own electricity with solar can offer more predictable long-term costs and reduce how much you rely on the grid each month.

Illinois Solar Incentives
Several solar incentives in Illinois can help Naperville homeowners lower the upfront and long-term costs of going solar.
As a ComEd customer, you may qualify for the DG Smart Inverter Rebate of $300 per kW, plus rebates for battery storage. Programs like Illinois Solar for All also support income-eligible households.
While the federal 30% tax credit has ended, Illinois net metering and a 20-year solar property tax exemption still apply. LightReach leasing simplifies incentives, since Palmetto handles the commercial ITC and reflects savings in lower monthly payments.

Illinois Solar for All (ILSFA) is a state program designed to make solar accessible to low- and moderate-income households, including residents of Naperville. To qualify, your household income must be at or below 80% of the Area Median Income (AMI) for your county. As a benchmark, a single-person household in Cook County qualifies with income under approximately $65,000. There is no credit check required, and initial income self-attestation is permitted.
Through ILSFA, an Approved Vendor installs a solar system at no upfront cost. Participants typically pay around $25/month for 15 years (approximately $4,500 total), after which the system transfers to them at no additional cost. The program legally guarantees a minimum of 50% savings on the retail value of the solar energy the system produces. Participants can choose to purchase with cash, a loan (with no prepayment penalties and no lien on the home), or through a lease or Power Purchase Agreement (PPA).
Important note for 2026: Single-family residential capacity was reached in 2025, so new applicants will need to join a waitlist for the 2026–27 program year cycle, which opens in June 2026. Visit illinoissfa.com to check eligibility and join the waitlist.
ComEd and Ameren Illinois offer a Distributed Generation (DG) Smart Inverter Rebate of $300 per kilowatt (kW) of solar capacity installed. For a typical 8.5 kW residential system, this translates to $2,550 back in your pocket. The rebate is paid as cash within approximately 60 days after your system receives Permission to Operate (PTO) from the utility.
To be eligible, your solar system must include a qualifying “smart” inverter. This rebate is available exclusively to customers of ComEd (northern Illinois) and Ameren Illinois (central and southern Illinois) — customers of most municipal utilities or electric cooperatives do not qualify. Homeowners in Naperville are served by ComEd. You do not need to enroll in a special rate plan to receive the solar-only portion of this rebate.
Contact ComEd at (800) 334-7661 or visit comed.com, or contact Ameren Illinois at (800) 755-5000 or visit ameren.com/illinois to apply and confirm current program availability.
In addition to the solar rebate, ComEd and Ameren Illinois offer a $300-per-kWh rebate for battery storage systems installed with a smart inverter. For a typical Tesla Powerwall 3 (13.5 kWh), this rebate can be worth approximately $4,000. The cash rebate is paid within approximately 60 days after your system receives Permission to Operate.
To qualify for the battery storage rebate, you must enroll in a specific utility rate plan: ComEd customers must select the Basic Electric Service Hourly (BESH) real-time pricing plan, while Ameren Illinois customers must enroll in the Peak Time Rewards demand response program. These rate plans are designed to align your battery usage with grid needs during peak demand periods.
This rebate is available only to ComEd and Ameren Illinois customers — not to customers of most municipal utilities or cooperatives. Contact ComEd at (800) 334-7661 or visit comed.com, or contact Ameren Illinois at (800) 755-5000 or visit ameren.com/illinois for application details and to confirm current program status.
The Virtual Power Plant (VPP) program is a new battery storage incentive created by the Clean and Reliable Grid Affordability Act (CRGA), signed into law on January 8, 2026. Utilities are required to launch the short-term VPP program no later than June 30, 2026. Residential customers who enroll their battery storage system in the VPP can receive the same $300/kWh distributed storage rebate as the standard DG program — without needing to enroll in the BESH or Peak Time Rewards rate plans.
In a VPP, the utility can briefly direct your battery to discharge electricity to the grid during high-demand periods, helping stabilize grid reliability. In exchange, you receive the upfront rebate and potentially ongoing compensation for your participation in dispatch events. This makes battery storage financially attractive for homeowners who may not otherwise qualify for or want to enroll in the standard DG rebate’s required rate plans.
A longer-term VPP program is also authorized to launch by December 31, 2028, which will expand eligibility to additional devices including smart thermostats and EV batteries. For more information, visit the Illinois Power Agency at ipa.illinois.gov or contact your utility.
Illinois law requires ComEd and Ameren Illinois to offer net metering for residential solar systems up to 25 kW. If your solar system was interconnected and operational before January 1, 2025, you are grandfathered into full retail-rate net metering for the lifetime of your system — meaning excess electricity you send to the grid is credited at the full retail rate (roughly 12–15¢/kWh).
For new solar installations interconnected on or after January 1, 2025, Illinois has transitioned to a policy called Smart Solar Billing. Under this model, credits for excess generation apply only to the supply portion of your electricity bill — not delivery charges or fixed fees. This results in a lower effective credit rate of approximately 6–8¢ per kWh depending on your utility, which is roughly half the value of legacy net metering. This makes it especially important to size your system carefully to maximize self-consumption.
Unused credits can roll over month-to-month. For full details on your specific utility’s net metering or Smart Solar Billing policy, visit comed.com or ameren.com/illinois.
Under Illinois law (35 ILCS 200/10-10), the added value that a solar energy system contributes to your home is excluded from your property tax assessment for 20 years. Solar panels typically increase a home’s market value by $15,000–$25,000, but without this exemption, that increase could add $250–$750 or more to your annual property tax bill. The exemption ensures you capture the full financial benefit of your solar investment without a tax penalty.
The exemption applies statewide to qualifying residential solar installations, including homes in Naperville. To claim it, you must file Form PTAX-330 (Solar Energy System Assessment Freeze) with your local county assessor after your system is installed. The exemption is not automatic — you must apply to receive it.
For more information on the exemption and to download Form PTAX-330, contact your county assessor’s office or visit the Illinois Department of Revenue at tax.illinois.gov.

Leasing Solar Panels
In Naperville, your electricity comes from ComEd, where Palmetto offers a solar Power Purchase Agreement (PPA) through LightReach. Instead of paying upfront for a system, you simply pay a set price for each kilowatt-hour (kWh) of clean energy your panels produce. Learn more about how this compares in our guide on whether to buy or lease solar.
With a PPA, there’s no large investment to recoup and no maintenance to manage yourself. Palmetto owns the system, handles repairs, and keeps everything running—so you can enjoy the savings without the responsibility of ownership.
Because production shifts with the seasons, your PPA payments may be higher in sunny summer months and lower in winter, though savings even out over the year. To see if it fits your home, explore LightReach.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes, Naperville homeowners have access to net metering. Because your electricity comes from ComEd, you’ll follow Illinois’ statewide policy. Systems interconnected before January 1, 2025 earn full retail-rate credits, while newer systems receive supply-only credits under Smart Solar Billing.
With net metering, extra electricity your panels send to the grid earns credits that help offset future bills. Unused credits roll over month to month, making it easier to balance summer production against winter usage.
Yes, in Naperville, solar panels can increase your home value—but this applies to purchased or owned systems, not leased ones. A Zillow study found homes with solar sell for about 4.1% more.
With a leased or PPA system, resale works differently, since the buyer may need to assume the lease agreement. Illinois also offers a 20-year property tax exemption on the added home value from owned solar.
In Naperville, the most affordable way to go solar is with a LightReach lease, starting around $79/month for a medium home with no upfront cost. Palmetto owns and maintains the system while you enjoy the savings.
You can also buy a system with cash, starting near $28,000 for an average home. Note that the federal 30% tax credit is no longer available for residential cash purchases after the 2025 law change. See the calculator above for pricing by home size.
With a solar lease like Palmetto’s LightReach program, you make one simple monthly payment that covers everything: the panels, installation, monitoring, maintenance, and a 90% Production Guarantee. There’s no upfront cost, and because Palmetto owns the system, it claims the commercial tax credit and passes those savings to you through lower payments.
For a typical 9.84 kW system in Naperville, the estimated payment is about $79/month. Since that’s often less than your current electric bill, many homeowners start saving right away.
Choosing a solar company in Naperville comes down to experience, quality installations, and honest guidance. At Palmetto Solar, we combine national resources with a local focus, having completed over 9,050 installations across Illinois since 2020.
We offer some of the best financing options in the industry, including LightReach leasing with no upfront cost, along with a trusted install network. Our goal is to make going solar clear, affordable, and reliable for Naperville homeowners.
Solar panels are low maintenance. With no moving parts, they typically only need occasional cleaning, and Naperville’s rain and snow often rinse them naturally. Panels are also built to withstand Illinois weather year-round.
If you lease with LightReach, Palmetto owns the system and handles all maintenance, monitoring, and repairs at no extra cost. This includes a 90% Production Guarantee, so your system keeps performing without any effort on your part.
For many Naperville homeowners, solar can make financial sense, especially as ComEd rates continue to climb. With a LightReach lease, there’s no upfront investment, and your monthly payment is typically less than your current electricity bill, so you can start saving from day one.
Because Palmetto owns and maintains the system, you avoid repair costs and simply enjoy predictable, lower energy costs. Illinois net metering and a 20-year property tax exemption can add to those long-term savings.
