Solar Cost in Philadelphia, PA

Estimate residential solar cost, annual production and savings in Philadelphia. Adjust system size, installed price, value captured and verified incentives using local and state 2026 planning data.

Federal residential solar credit in 2026: $0. CalcuRiver does not subtract the expired 30% Section 25D credit from this estimate. Add only local or utility incentives you have independently verified.

“Value captured” is deliberately editable because self-consumption, export credits and net-metering rules vary by utility. 100% represents a retail-value ceiling, not a guaranteed bill saving.

Solar by electric utility

Utility export rules can change solar value even when the roof and production estimate stay the same. Choose the utility that serves your address.

UTILITY-SPECIFIC SOLARPECOTariff boundary

How this Philadelphia estimate works

  • Annual production = system size × 1,357 kWh/kW planning yield.
  • Retail-value ceiling = annual production × current Pennsylvania 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.

1,357 kWh/kW-year planning benchmark derived from a PVWatts-modeled city output table; planning value, not a site-specific roof forecast. Roof orientation, shading, equipment, weather year and utility export compensation can materially change the result.

No artificial numeric difference. The current Pennsylvania state planning benchmark is anchored to the same city-level production/cost input used for Philadelphia, so production, benchmark cost and simple payback currently match. The city page remains source-specific rather than inventing a difference.

Data basis: Direct city source; state benchmark currently matches this city input · production source: PVWatts-based 2026 city benchmark · electricity benchmark: EIA 2026-07 · federal residential credit modeled: 0%.

methodology & sources

Philadelphia solar methodology

Production precision: sourced city/representative-city planning benchmark; not a site-specific roof forecast.

Production basis

1,357 kWh/kW-year planning benchmark. This is a planning input, not a site-specific roof forecast.

Installed-cost basis

2.88 $/W planning benchmark for this city/region; not an installer quote.

Electricity benchmark

21.72¢/kWh Pennsylvania 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 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.
