How this Oakland estimate works
- Annual production = system size × 1,685 kWh/kW planning yield.
- Retail-value ceiling = annual production × current California residential electricity price.
- The value-capture control lets you haircut that ceiling for self-consumption/export economics.
- Simple payback = entered net installed cost ÷ modeled annual electricity value.
Source boundaries
1,685 kWh/kW-year planning benchmark based on CalcuRiver's California representative-city PVWatts planning value; planning input, not a site-specific roof forecast. Roof orientation, shading, equipment, weather year and utility export compensation can materially change the result.
What is localized in Oakland
State/regional fallback. Production, installed cost and retail-value payback currently match the California benchmark. CalcuRiver does not manufacture a city-level difference until a stronger local production, cost or utility input is available.
Data basis: State / regional fallback · production source: PVWatts-based state planning benchmark · electricity benchmark: EIA 2026-07 · federal residential credit modeled: 0%.
Oakland solar methodology
Production precision: state/regional benchmark disclosed for Oakland; no unverified city-specific production uplift is applied.
Production basis
1,685 kWh/kW-year planning benchmark. This page explicitly uses the state/regional fallback rather than claiming site-specific city precision.
Installed-cost basis
2.50 $/W planning benchmark for this city/region; not an installer quote.
Electricity benchmark
33.61¢/kWh California residential benchmark for 2026-07.
Utility boundary
The city page does not assume one electric utility. Use an available city × utility page when the service territory is verified.

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.
