What will 25 years of rising electric rates cost your home?
Illinois power prices keep climbing. See what staying on the grid could cost you over the next 25 years — and how much solar and battery could offset. Built only for ComEd and Ameren homes.
Get the real numbers first. Decide on your own terms.
Most solar pitches open with a promise. We open with your actual bill, your utility, and public rate data — so you can judge for yourself whether a closer look is even worth your time.
Illinois, specifically
Built only for ComEd and Ameren homes — where the rules, grids, and rate paths actually differ. No generic national claims.
Every number is sourced
Each rate and program figure links to a public source you can open yourself: CUB, Plug In Illinois, PJM, MISO, and Illinois Shines.
No pressure, ever
The next step is a quick eligibility check — not a commitment to buy, switch suppliers, or sign anything. You stay in control.
Solar and battery together
We weigh backup power, usage, and storage alongside panels — the way the decision actually works for a real home.
See what doing nothing could cost you.
Match it to your home and watch the chart move. Every figure is an honest estimate — and you control every assumption behind it.
A starting estimate from typical Illinois usage. Know your real bill? Switch to “I know my bill” for a closer number.
An assumption you control — not a prediction. Illinois supply prices recently jumped far more than this in a single year.
The share of your power a well-sized system might cover. Most good-fit homes land near 80–100%.
(estimate, before system cost)
How these estimates work. Figures are illustrative estimates, not a quote, guarantee, or promise of savings. The 25-year cost compounds your monthly bill at the annual increase you select. The “offset” figure is the gross share of that utility cost a system might cover — capped at 100% of your bill, and it does not include system price, financing, taxes, or incentives, which a full review covers. System size is a rough estimate using standard Illinois solar production. When estimating from home size, we assume typical Illinois usage of about 0.40 kWh per sq ft each month for gas-heated homes and 0.75 for electric-heated homes, at an estimated all-in rate of ~16.5¢/kWh (ComEd) or ~15.5¢/kWh (Ameren). Your real numbers depend on your home, roof, shade, usage, system design, and final terms. Rate data last reviewed June 2026 — sources: Plug In Illinois and the Citizens Utility Board.
This isn't a sales pitch. It's the public record.
The pressure on Illinois bills is real and documented — driven by grid-capacity costs and surging demand from data centers. Here's where the numbers come from, in their own words.

Solar answers the bill. Battery answers the blackout.
For most homes it's no longer “solar or nothing.” A review looks at whether each piece actually fits your roof and your usage — before anyone talks system size or price.
Take control of a rising bill
Generate power on your own roof instead of buying every kilowatt-hour at a rate that keeps climbing.
Keep the lights on in an outage
Battery storage can power your home when the grid goes down — depending on system design, battery size, and how you use energy.
Tap Illinois program value
Illinois Shines pays Renewable Energy Credits to participating vendors — value that may reach you through lower project or power costs, depending on the agreement. See the full Illinois incentive stack.
This review is built for a specific kind of home.
Owner-occupied homes are the cleanest fit — roof and long-term usage can be reviewed properly.
A roof and property that can actually be designed around for solar and battery.
The review is built for these two territories, where the rules and rate paths differ.
Higher usage usually makes the numbers more meaningful than a very low bill.
Three steps. Zero wasted appointments.

Answered before you continue.
Does checking eligibility obligate me to anything? +
No. The eligibility check simply shows whether a full review makes sense for your home. It doesn't commit you to buy, switch suppliers, or sign a contract.
Are the calculator results a guarantee of savings? +
No. The calculator gives illustrative estimates, not a quote or a promise. You control the assumptions, and the figures don't include system price, financing, taxes, or incentives. Your real numbers come from a full review of your specific home.
How do you estimate my bill from square footage? +
If you don't know your bill, we estimate usage from your home's size and heat source using typical Illinois figures, then apply your utility's rate. It's a starting estimate — if you know your actual bill, that option gives a closer number.
Why does it matter whether I'm with ComEd or Ameren? +
Illinois program details, rates, and review steps differ by utility — ComEd is on the PJM grid and Ameren is on the MISO grid. That's why the first question is which company serves your home.
Who contacts me if I continue? +
Our review team or an authorized partner may reach out using the information you provide, to discuss your eligibility and possible next steps.
