Philadelphia's price band
Philadelphia is pricier than 67% of the 195 US metros we price for solar panel work.
Expect $18,500–$29,100 for 8 kW of panels, $22,450–$35,350 for 10 kW, and $11,550–$18,550 more for a Tesla Powerwall 3. Every price here is before incentives, and the federal homeowner credit is gone for 2026 installs.
Philadelphia row homes have flat or low-slope roofs and often older electrical service, so tilt racking and a main panel upgrade show up on many quotes. PECO handles the hookup.
The federal 30% Residential Clean Energy Credit ended for expenditures after December 31, 2025, and the IRS counts the expense when installation is finished, so a system completed in 2026 gets no federal credit even if you paid in 2025.

Prices cover the Philadelphia metro and assume a pitched shingle roof in good shape. Older roofs in North Philly more often need repair first.
Solar panel prices across Philadelphia
The panels cost the same across Philadelphia; the roofs do not. Flat and older roofs in Center City & Fishtown push labor up, and big simple roofs in South Philly, Delco & the suburbs keep it down.
Center City & Fishtown
- 8 kW installed
- $19,600–$31,450 installed
- Typical job
- $15,400–$38,200 / 6–10 kW system
Flat roofs, older buildings and little street parking. Arrays here often need tilt racking or weighted mounts, fire-code walkways cut the panel count, and permit reviews take longer.
North Philly
- 8 kW installed
- $19,050–$30,250 installed
- Typical job
- $15,000–$36,750 / 6–10 kW system
Older homes with character roofs and 100-amp panels. Ask early whether the roof has 10 years of life left and whether the job needs a panel upgrade.
West & Southwest Philly
- 8 kW installed
- $18,500–$29,100 installed
- Typical job
- $14,550–$35,350 / 6–10 kW system
Middle-of-the-range jobs. Good roof space on most homes; tree shade is the thing to check.
South Philly, Delco & the suburbs
- 8 kW installed
- $18,150–$29,100 installed
- Typical job
- $14,250–$35,350 / 6–10 kW system
Newer tracts with 200-amp panels and wide roofs keep labor down. HOA review of the layout is common, so allow time for it.
Real solar jobs in Philadelphia
Here's what common solar panel jobs cost in Philadelphia in 2026, installed, before incentives.
Smaller home: 6 kW, standard panels
About 23 kWh on an average day at Pennsylvania's sun levels. Smaller systems cost more per kW, about $2,950 here against $2,800 for 8 kW.
Typical home: 8 kW, standard panels
About 31 kWh a day and 11,200 kWh a year. $22,550 is the typical Philadelphia price for a pitched shingle roof in good shape.
Solar plus a Powerwall 3
An 8 kW system with a 13.5 kWh battery for outages and evening use. Doing both in one job shares the crew, the permit and the utility paperwork.
Big home or EV owner: 10 kW, premium panels
Premium panels make more power per square foot, which helps on small or shaded roofs. Standard panels at 10 kW are $22,450–$35,350.
Re-roof with solar already on it
Taking about 20 panels off and putting them back after the roofers leave, on top of the roof itself. If your roof has less than 10 years left, replace it before solar goes on.
How much do solar panels cost in Philadelphia?
Between $18,500 and $29,100 for an 8 kW system, installed, and most Philadelphia homeowners pay close to $22,550. Three things set the number: system size, panel brand and the roof. A simple shingle roof with standard panels lands near the low end; premium panels on a steep or tile roof can pass $36,400.
There is no federal credit to take off these numbers any more. What still cuts the bill in Philadelphia is a second or third quote, the right system size for your actual use, and any state or utility program. Figures re-verified against 42 sources in November 2026.
Solar prices in Philadelphia (2026): the lines on a quote
An 8 kW system is $18,500–$29,100 installed, a battery adds $9,050–$18,550, and a panel upgrade adds $1,500–$4,500 if your panel is full.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| 8 kW system, standard panels | $18,500 | $22,550 | $29,100 |
| 8 kW system, premium panels | $20,350 | $25,900 | $36,400 |
| Tesla Powerwall 3, added at install | $11,550 | $14,800 | $18,550 |
| Main panel upgrade (to 200 amps) | $1,500 | $2,500 | $4,500 |
| Tile roof, extra | $1,000 | $1,750 | $2,500 |
| Ground mount, extra | $4,050 | $6,550 | $10,050 |
| Critter guard | $700 | $1,200 | $1,700 |
| String inverter replacement (later) | $1,500 | $2,300 | $3,500 |
Standard vs premium panels in Philadelphia: the gap on 8 kW is about $3,350. Premium panels pay off on small or shaded roofs where you need more power per square foot; on a big sunny roof, standard panels are the better buy.
What moves a solar quote in Philadelphia:
- System size — bigger systems cost less per kW: about $2,950 at 6 kW against $2,750 at 10 kW.
- Panel and inverter brand — premium panels run 10–25% more; microinverters cost more than one string inverter but last longer.
- The roof — tile adds $1,000–$2,500, a ground mount $4,050–$10,050, and a worn roof should be replaced first.
- The electrical panel — a full or 100-amp panel can add $1,500–$4,500 for an upgrade.
- Who sells it — sales and marketing are about 15% of a typical price; local installers often quote less than national brands.
Ask every Philadelphia installer for the same five things: system size in kW, panel and inverter models, the price per kW, the warranty terms, and what roof, panel and permit work is included. Compare those lines, not the total. Get a quote for your solar install →
Solar Panel Cost in Philadelphia by System Size
A 6 kW system is $14,550–$22,850, 8 kW is $18,500–$29,100, and 10 kW is $22,450–$35,350, installed with standard panels, before any state or utility incentive.
Worked example: a Philadelphia home using about 930 kWh a month gets an 8 kW system at $22,550. If the panel is 100 amps, add an upgrade at $2,500 for $25,050. Add a Powerwall 3 in the same job and the total is about $39,100.
A larger home with central AC or an EV may need 10–12 kW: $27,400 for 10 kW, or $33,700 for 12–13 kW at typical prices. Premium panels on 10 kW run $24,700–$44,200.
Philadelphia Solar Panel Costs by System Size
| System size | Cost | Best for |
|---|---|---|
| 4 kW system — about 15 kWh a day | $10,750–$16,950 installed | Small home or condo; low bills or a small roof |
| 6 kW system — about 23 kWh a day | $14,550–$22,850 installed | Smaller home or modest power use |
| 8 kW system — about 31 kWh a day | $18,500–$29,100 installed | Typical home; about 930 kWh a month of use |
| 10 kW system — about 38 kWh a day | $22,450–$35,350 installed | Larger home, central AC or one EV |
| 12 kW system — about 46 kWh a day | $26,750–$42,100 installed | Big home, pool or electric heat |
| 15 kW system — about 57 kWh a day | $32,250–$50,750 installed | Very large all-electric home or two EVs |
| 8 kW solar + 13.5 kWh battery | $29,450–$46,700 installed | Backup in outages and evening use where exports earn little |
| 13.5 kWh battery only (no solar) | $11,550–$18,550 installed | Backup without panels; shaded roofs |
Hardware vs everything else: where a Philadelphia solar quote goes
Panels, inverter, racking and wiring are only about 41% of a typical US solar price. On a $22,550 Philadelphia job that is roughly $9,250. Sales and marketing take about 15%, design, paperwork and overhead about 20%, installer profit about 16%, and the install labor itself only about 6%.
That is why the payback math matters more than the panel brand. An 8 kW system here makes about 11,200 kWh a year. At Pennsylvania's 2024 average of 12.5 cents a kWh across all customers (EIA; home rates usually run higher), that power is worth about $1,400 a year, a simple payback near 16 years. That assumes your utility credits exports at the full rate; lower export credits stretch it, and higher home rates shorten it.
What's included in a Philadelphia solar quote (and what costs extra)
A standard quote covers the panels, inverter, racking, wiring, the install crew, permits, inspection and the utility hookup paperwork. The headline price often leaves out:
- Roof work — repairs, or $1,000–$2,500 extra for a tile roof
- Panel upgrade — $1,500–$4,500 if your electrical panel is full or 100 amps
- Critter guard — $700–$1,700 to keep birds and squirrels out from under the panels
- A battery — $9,050–$18,550 for 10–13.5 kWh of storage, if you want backup
Get the warranty terms in writing: panel and inverter years, the workmanship warranty, and who fixes roof leaks around the mounts.
What's local
Philadelphia row homes have flat or low-slope roofs and often older electrical service, so tilt racking and a main panel upgrade show up on many quotes. PECO handles the hookup.
System size
An 8 kW system is $18,500–$29,100. A 6 kW system is $14,550–$22,850 and 10 kW $22,450–$35,350; the price per kW drops as the system grows.
Panels and inverters
Premium panels add 10–25% ($20,350–$36,400 for 8 kW). Microinverters cost more upfront than one string inverter but usually carry 20–25 year warranties; a string inverter often needs replacing once ($1,500–$3,500).
Your roof
Clay or concrete tile adds $1,000–$2,500, a ground mount $4,050–$10,050. If the roof has less than about 10 years left, re-roof first: removing and reinstalling panels later costs $3,500–$8,050.
Your electrical panel
A full or 100-amp panel is a common surprise. Upgrading to 200 amps adds $1,500–$4,500 in Philadelphia, and it is cheapest done with the solar job.
Adding a battery
A 10–13 kWh battery adds $9,050–$17,050, a Tesla Powerwall 3 $11,550–$18,550. Batteries make the most sense where outages are common or exports earn little.
Permits and the utility in Philadelphia
Permits and inspections are about 3% of a typical price, and the utility must approve the hookup before you can switch on. Ask who files the paperwork; a good installer does all of it.
- Get three quotes.Same panels, different sales costs. Philadelphia quotes for 8 kW run $18,500–$29,100; a second and third bid is the fastest way to find the padding.
- Compare the price per kW.Divide each quote by its size in kW. About $2,300–$2,800 per kW is a good Philadelphia price for standard panels; much above $3,600 needs a reason.
- Size it to your bills, not your roof.Use 12 months of bills. A system that makes more than you use only pays off if your utility credits exports well.
- Fix the roof first.Re-roofing under existing panels means paying $3,500–$8,050 to take them off and put them back.
- Bundle the panel and battery work.A panel upgrade ($1,500–$4,500) or a battery done in the same job shares the permit, the inspection and the utility visit.
- Check state and utility help.Ask your utility about rebates and how it credits exports before you sign.
Before you pay a deposit to a Philadelphia solar installer, get these in writing:
- System size in kW and the expected output in kWh a year
- Panel and inverter brand and model
- Price per kW and the total before incentives
- Roof work, tile or ground-mount extras, priced as their own lines
- Any panel upgrade, priced as its own line
- Permit, inspection and utility interconnection, and who files them
- Warranties: panels, inverter, workmanship and roof leaks
- Payment schedule, and what happens if the utility hookup is delayed
How much do solar panels cost in Philadelphia?
$18,500–$29,100 installed for an 8 kW system, and $22,550 is typical. A 6 kW system is $14,550–$22,850 and 10 kW is $22,450–$35,350, before incentives.
What is the price per kW for solar in Philadelphia?
About $2,800 per kW for an 8 kW system with standard panels, within $2,300–$3,600. Smaller systems cost more per kW and larger ones less.
Is there still a federal solar tax credit in Philadelphia?
Not for systems you buy. The 30% Residential Clean Energy Credit ended for expenditures made after December 31, 2025, and the IRS treats the expense as made when installation is complete. Lease and PPA companies may still claim a business credit and pass some of it on in their price.
How much does solar with a battery cost in Philadelphia?
About $29,450–$46,700 for 8 kW of panels plus a Tesla Powerwall 3. A 10–13 kWh battery from another brand adds $9,050–$17,050 to the solar price.
How long does solar take to pay off in Philadelphia?
Roughly 16 years for a typical 8 kW system at Pennsylvania's 2024 average power price from EIA (12.5 cents a kWh across all customers), with every kWh worth the full price. That assumes your utility credits exports at the full rate; lower export credits stretch it, and higher home rates shorten it.
How much power will an 8 kW system make in Philadelphia?
About 31 kWh on an average day, or 11,200 kWh a year, based on about 4.8 peak sun hours a day for Pennsylvania in NREL data.
Do I need a new electrical panel for solar in Philadelphia?
Not always. Many 200-amp panels take solar as they are. A full or 100-amp panel may need an upgrade, about $1,500–$4,500 here.
What does solar panel cleaning and upkeep cost in Philadelphia?
Cleaning is $150–$500 a visit and a health check $150–$350. Many roofs never need cleaning; rain does most of it. Budget $1,500–$3,500 for one string inverter replacement over the life of the system.
How much does it cost to remove solar panels for a new roof in Philadelphia?
$3,500–$8,050 to take about 20 panels off and put them back, on top of the roof itself.
What permits does solar need in Philadelphia?
A building or electrical permit, an inspection, and the utility's approval to connect. Your installer should file all of it; permits and inspections are about 3% of a typical price.
