ComEd Solar Cost & Rate Context in Illinois

Estimate production and installed cost in ComEd electric service territory in northern Illinois while keeping unverified solar export compensation out of the result.

Federal residential solar credit in 2026: $0. The utility export program is verified, but exact export value remains guarded until customer-specific billing inputs are known.

Exact ComEd export value requires the customer’s supply arrangement and fixed or hourly pricing context. CalcuRiver therefore shows a retail-value ceiling rather than pretending all exports receive the full retail rate.

methodology & sources

What is modeled — and what is not

Production

1,301 kWh/kW-year state planning benchmark from the existing PVWatts-based CalcuRiver dataset.

Installed cost

$2.96/W planning benchmark for Illinois.

Electricity value ceiling

19.22¢/kWh · EIA residential benchmark for Illinois (2026-07).

ComEd rate context

14.56¢/kWh · Non-summer fixed-price marginal benchmark. This is utility rate-plan context, not a verified solar export-compensation rate.

Utility source: ComEd 2026 residential line-item summary and ICC rate book · verified 2026-09-29.

Production: NREL PVWatts methodology · Cost: 2026 state / local marketplace benchmark.

Solar export source: ComEd 2026 Net Metering FAQ · ComEd Hourly Pricing — Solar Generation · verified 2026-10-03.

why this estimate changes

Why this solar estimate changes

Solar value is driven by local production, installed cost, the retail value of electricity you avoid buying, and the compensation you receive for exported energy. CalcuRiver does not assume export credits equal the retail rate unless that utility program is explicitly verified.

Core logic: self-used solar offsets retail purchases; exported solar is valued only under a verified export-compensation rule.

Connect solar to the rest of the utility bill

Solar economics are easier to interpret when the tariff, storage and vehicle loads are connected to the same local context.
