methodology & sources

What is modeled — and what is not

Production

1,261 kWh/kW-year state planning benchmark from the existing PVWatts-based CalcuRiver dataset.

Installed cost

$2.73/W planning benchmark for Connecticut.

Electricity value ceiling

24.16¢/kWh · EIA residential benchmark for Connecticut (2026-07).

Eversource Connecticut rate context

20.24¢/kWh · Rate 7 off-peak snapshot. This is utility rate-plan context, not a verified solar export-compensation rate.

Utility source: Eversource Connecticut Rate 7 tariff and residential VPP price snapshot · verified 2026-09-29.

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

Why exact Eversource Connecticut solar savings stay guarded

CalcuRiver has a calculator-ready utility rate profile for Eversource Connecticut, 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 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.
