Solar Panel Installation Cost in Pennsylvania (2026)

In Pennsylvania, solar panel installation cost for the typical project costs about $17,200 — 1% above the national average of $17,100. The gap comes from labour: Pennsylvania labour runs at 1.02× the national average, and labour is about 30% of an installed price, so the state figure below scales the labour share only and leaves material prices at national levels. Read the national guide for the full breakdown, then use this page for the Pennsylvania numbers, city prices and code notes.

Typical project used for these figures: a 6 kW rooftop system — 15 × 400 W panels, string inverter, no battery — on a straightforward single-storey roof. Ranges are 2026 planning figures for a professional installation in Pennsylvania, derived from the national guide as explained below — always confirm with local quotes.

Pennsylvania prices vs the national average

Materials for this project are priced nationally — a bundle of shingles or a pallet of panels costs roughly the same anywhere in the country before delivery. Labour is what moves, and Pennsylvania labour sits at 1.02× the national average. Applying that index to the labour share (about 30% of the installed price) gives the Pennsylvania range below. If your quotes cluster well outside it, the difference is usually specification — material grade, code extras or site difficulty — not the labour market, and it is worth asking which line moved.

Cost breakdown, Pennsylvania-adjusted

The national guide's line items, with materials held at national prices and labour scaled by the Pennsylvania index of 1.02. Compare a real bid against this table line by line: if a contractor's labour lines run far above these figures, ask what is different about the job, and if the materials lines run far above, ask for the product grades.

Typical cost by city in Pennsylvania

Labour markets differ within a state too. These city figures apply each city's multiplier to the Pennsylvania typical price for the same project — use them to sanity-check a quote from a specific metro, not as a bid. Rural areas outside these metros often land below the cheapest city shown, while resort and island markets can exceed the highest.

CityTypical project cost
Erie$15,850
Scranton$15,850
Harrisburg$16,500
Allentown$16,850
Pittsburgh$17,200
Philadelphia$18,250

Pennsylvania rules, climate and code that change the price

Pennsylvania follows the Uniform Construction Code statewide, but enforcement sits with municipalities, so permit practice and inspection rigour vary between Philadelphia, Pittsburgh and small townships. Frost depth runs 36–42 in across much of the state, so footings for decks, fences and porches must go well below grade, and snow loads in the northern tier and the Alleghenies affect roof and deck design. Philadelphia adds its own licensing and permit layers on top of the state code.

Solar Panel Installation Cost in Pennsylvania: what to watch

Pennsylvania solar runs on net metering, the federal credit and solar renewable energy credits (SRECs), whose market price varies — a quote that assumes a high SREC value flatters its payback. Snow and the state's moderate sun hours mean production estimates must be location-specific, not national averages, and the roof's remaining life matters: Pennsylvania's older housing stock often needs a re-roof before panels go on. Philadelphia adds row-house access and party-wall considerations. Ask for the production estimate's weather source and the SREC assumption in writing.

What to ask contractors in Pennsylvania

Four questions that catch the expensive surprises on this project in this state. Get the answers in writing, on the quote, before you compare prices — two quotes are only comparable when they describe the same job.

  • Permit: Pennsylvania municipalities enforce the Uniform Construction Code locally, so permit requirements for roofing, decks and remodels are near-universal but the office, fees and inspection schedule depend on the municipality. Philadelphia has additional licensing and permit requirements beyond the state code.
  • Specification: Ask for the full material specification — grades, ratings and the code extras in the state notes above — not just a brand name and a total.
  • Labour basis: Ask how the quote treats the Pennsylvania labour market: a quote far above the $17,200 typical figure should name the extra work, access problem or specification that justifies it.
  • Local references: Ask for two recent jobs in your city, not just your state — city prices above vary by thousands, and a contractor working regularly in your metro knows its permit office and inspectors.

Frequently asked questions — Pennsylvania

How to read these numbers. Last updated October 2026 · Pennsylvania figures are derived from the national guide by scaling the labour share (about 30% of the installed price) by the Pennsylvania labour index of 1.02; materials are held at national prices. State indices are planning-grade figures compiled from published regional cost data, not contractor quotes. Always confirm with local quotes; your quote will vary.
