Major utility solar profiles in Illinois
Solar payback can change materially by utility because retail rates, time-of-use periods, fixed charges and export compensation are not the same statewide. Check the utility rules that apply to the property before trusting a proposal's savings estimate.

- Request at least three written proposals and compare the solar-only cash price before financing.
- Check the exact panel, inverter and battery model numbers instead of accepting broad equipment descriptions.
- Compare annual production assumptions and verify that roof direction, shading and system size are realistic.
- Confirm contractor licensing, permits and required inspections with the appropriate state or local authority.
- Read workmanship, roof-penetration, equipment and production guarantees separately.
- Use the same electricity-rate and export-compensation assumptions when comparing payback claims.
Data and listing methodology
Live installer discovery uses Google Maps Platform results and does not imply verification, ranking, matching-partner status or endorsement by Home Solar Atlas. We do not create installer profiles from unverified claims. When a publishable homeowner quote sample exists, state price pages may show privacy-thresholded pricing observations by installer name; those observations describe proposal pricing only and are not installer ratings.
U.S. EIA Electric Power Monthly, Table 5.6.B, Year-to-date through June 2026, is used for the state electricity-rate reference. State solar yield is a planning estimate derived from NREL residential PV resource-class ranges, not a site-specific PVWatts result.
