How to read this guide

GridPermit collects Pennsylvania residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.

Permit timeline

0–20 days

Per the City's own page: EZ permits are issued same-day for in-person applications or within 3 business days for online applications; standard (non-EZ) applications take 20 business days; an accelerated review option returns results in 5 business days for an additional $1,050 fee. This same-day figure is explicitly tied to the City's own named EZ Permit program (a real, confirmed program name, not an inferred platform).

Utility and generation supplier

Utility

PECO Energy Company (an Exelon company)

PECO is Philadelphia's well-established dominant electric utility.

Generation supplier

PECO Energy Company (utility)

Pennsylvania is a retail-choice state — customers may select an alternate Electric Generation Supplier (EGS) for generation while PECO remains the distribution utility. PECO's own materials note that customers who switch to an EGS lose PECO's annual net-metering true-up compensation. PECO is recorded as the default generation/distribution utility for customers who do not choose an alternate EGS.

Per PECO's own published guide (updated September 2024): for monthly metered customers, PECO credits each kWh received up to the total electricity PECO delivered that billing period, netting monthly usage to zero (customers still owe the monthly customer charge and other rate-schedule charges). Excess generation carries forward to future months; at the end of the PJM year (May 31), any remaining surplus kWh receives an annual true-up credit — but customers who switch to an alternate Electric Generation Supplier (EGS) lose this annual compensation. PECO also offers Virtual Net Metering (VNM), letting customers with multiple PECO accounts within 2 miles of the host property allocate solar credits across those accounts (restricted to residential/small-commercial default-service customers under 100kW peak demand, and unavailable to customers using an alternate EGS). Net metering requires a dedicated bidirectional meter installed by PECO. A separate application fee (varying by system size/level) applies for the interconnection safety/reliability review, per PECO's own materials — specific dollar figures were not confirmed from this document.

Permit authority

City of Philadelphia Department of Licenses and Inspections (L&I)

Pennsylvania's Uniform Construction Code (UCC) is adopted statewide, but most municipalities enforce it through hundreds of separate local or third-party agencies — a genuinely fragmented model overall. Philadelphia is a significant exception: as a consolidated city-county with home-rule charter authority, its own Department of Licenses and Inspections is a single, large, well-documented AHJ for the entire city, distinct from the fragmented pattern in most of the rest of the state.
