What is modeled — and what is not
Production
1,538 kWh/kW-year state planning benchmark from the existing PVWatts-based CalcuRiver dataset.
Installed cost
$2.61/W planning benchmark for Oklahoma.
Electricity value ceiling
14.35¢/kWh · EIA residential benchmark for Oklahoma (2026-07).
OG&E rate context
4.06¢/kWh · Summer super off-peak incl. FCA. This is utility rate-plan context, not a verified solar export-compensation rate.
Utility source: OG&E R-EV-TOU tariff and June 2026 FCA factor sheet · verified 2026-09-29.
Production: NREL PVWatts methodology · Cost: 2026 state / local marketplace benchmark.
Why exact OG&E solar savings stay guarded
CalcuRiver has a calculator-ready utility rate profile for OG&E, but that does not automatically make the same plan a valid solar import/export tariff. Until a solar-specific compensation rule is verified, the calculator shows production, cost and a retail-value ceiling without flattening export compensation to an invented rate.

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.
Methodology & source policyConnect 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.
