According to MySolarFY’s analysis (as of July 2026), a typical 6 kW rooftop system in Fort Washington produces about 8,021 kWh a year (NREL PVWatts, ZIP 19034), which offsets roughly $1,680 on your PECO bill at Pennsylvania’s 20.92 cents per kWh residential rate (EIA, March 2026). Against a typical installed cost near $18,000 to $19,500 (about $3.00 to $3.25 per watt, SolarReviews and EnergySage, 2025), that points to an estimated payback of about 10 to 11 years before financing, with Pennsylvania SRECs adding income on top. These are estimates on cited inputs, not a quote, and the federal residential tax credit (Section 25D) ended December 31, 2025.
Fort Washington is an affluent, leafy community in Upper Dublin Township, Montgomery County, just north of Philadelphia, and it sits inside PECO’s electric territory, which is what shapes how rooftop solar pays here. Two things make Fort Washington, PA solar a bit different from a dense city block: the homes are mostly larger detached single-family houses with generous pitched roofs, so systems here often size bigger, and your permit runs through Upper Dublin Township rather than a borough. This page shows the real payback math for a Fort Washington roof, how PECO credits your exports, what a PA SREC adds, the incentives that actually apply, and the local permitting worth planning around. Then you can check your own address in about a minute.
What Fort Washington homeowners keep (updated for 2026)
The real payoff in Fort Washington comes from PECO’s full-retail net metering and the PA SREC market, not a state tax credit, and a typical 6 kW roof offsets roughly $1,680 a year at the local electricity rate. Here is the quick rundown.
- A 6 kW roof here makes about 8,021 kWh a year. That is a real NREL estimate for ZIP 19034, at 4.73 daily sun-hours and a 15.3% capacity factor (NREL PVWatts, as of July 2026), and bigger suburban roofs commonly go larger.
- PECO credits your solar at full retail through the year. Each kWh your roof exports offsets a kWh you use at the full retail rate, and any monthly surplus carries forward (52 Pa. Code 75.13, as of 2026).
- The power you offset is pricey. Pennsylvania residential electricity averages about 20.92 cents per kWh (EIA, as of March 2026), and PECO’s residential rate sits in that range, so every kilowatt-hour you make is one you do not buy back.
- PA SRECs pay you a second time. Your system earns one Solar Renewable Energy Credit per 1,000 kWh it produces, sold on a market that moves (DSIRE Pennsylvania AEPS, as of 2026).
- Pennsylvania has no state solar tax credit and no solar sales-tax exemption. The real PA benefits are net metering and SRECs, not a state credit (PA DEP Solar Resource Hub, as of 2026).
- The 30% federal homeowner credit (Section 25D) ended after December 31, 2025 (IRS, as of January 1, 2026), so a Fort Washington homeowner who buys solar in 2026 cannot claim it.
Key numbers for Fort Washington
- Pennsylvania residential electricity rate: about 20.92 cents per kWh, as of March 2026 (EIA).
- Typical 6 kW production for ZIP 19034: about 8,021 kWh per year, as of July 2026 (NREL PVWatts).
- Estimated annual PECO bill offset from that system: about $1,680, computed by MySolarFY from the EIA rate and the PVWatts production (July 2026).
- Estimated payback before financing: about 10 to 11 years, using a $3.00 to $3.25 per watt installed cost (SolarReviews, 2025; EnergySage, 2025).
- PA SREC: one credit per 1,000 kWh produced, sold at a market price, as of 2026 (DSIRE).
What a Fort Washington roof actually pays: the payback math
The reason solar pays in Fort Washington is the price of the power it replaces, and Fort Washington has room to build bigger. Pennsylvania residential electricity averages about 20.92 cents per kWh (EIA, as of March 2026), and PECO residential customers sit in that range. Because most homes here are larger detached houses, many roofs can carry an 8 kW or 10 kW array rather than a small-lot system, and more panels means more of that expensive grid power offset. The table below is our own estimate for this ZIP: it multiplies the real NREL PVWatts production for 19034 by the EIA rate, then divides a typical installed cost by the annual value, so you can see how the math scales with roof size.
| System size (Fort Washington, ZIP 19034) | Est. annual production | Est. annual PECO bill offset | Est. SRECs earned per year | Est. installed cost ($3.00 to $3.25/W) | Est. payback (before financing) |
|---|---|---|---|---|---|
| 6 kW | about 8,000 kWh | about $1,680 | about 8 | $18,000 to $19,500 | about 10 to 11 years |
| 8 kW | about 10,700 kWh | about $2,240 | about 11 | $24,000 to $26,000 | about 10 to 11 years |
| 10 kW | about 13,400 kWh | about $2,800 | about 13 | $30,000 to $32,500 | about 10 to 11 years |
Payback lands in the same range across sizes because cost and savings both scale with the system, so the reason to size up a bigger Fort Washington roof is more total lifetime savings and more SRECs, not a faster payback.
Method: 6 kW production is the NREL PVWatts v8 run for ZIP 19034 (8,021 kWh per year); 8 kW and 10 kW scale that figure by size. Offset uses the EIA PA residential rate of 20.92 cents per kWh (March 2026). Cost uses a $3.00 to $3.25 per watt installed range (SolarReviews, 2025; EnergySage, 2025). These are MySolarFY estimates on cited inputs, not a quote; payback also ignores SREC income, which shortens it, and financing costs, which lengthen it. Your roof’s pitch, shading, and usage change the result, so estimate yours with the free PVWatts calculator and a written quote.

How does PECO net metering work in Fort Washington?
PECO credits your exports at the full retail rate through the year, then trues up once a year. Pennsylvania net metering is set by state regulation, not by the utility, and a residential system up to 50 kW qualifies, which covers any normal Fort Washington home (PA PUC, as of 2026). Month to month, each kilowatt-hour your panels send to the grid offsets a kilowatt-hour you draw at full retail value, and any surplus in a billing period carries forward as a credit to the next month (52 Pa. Code 75.13, as of 2026). For the statewide mechanics, see our Pennsylvania net metering guide for 2026 and the plain-English explainer on how net metering credits your solar exports.
The one wrinkle to size around is the annual true-up. PECO settles the net-metering year at the end of your annualized service period, which lines up with the PJM planning year that ends May 31, and any kilowatt-hours left in your bank at that point are cashed out at PECO’s Price to Compare, the supply portion of the rate, rather than the full bundled retail rate (52 Pa. Code 75.13, as of 2026). The takeaway for a bigger Fort Washington roof: size your system close to your own annual usage so you capture full retail value all year, instead of banking a large surplus that settles at the lower year-end rate. You can read the utility-level detail on our PECO net metering and rates page.
| What your Fort Washington system earns | How it is valued | Who receives it |
|---|---|---|
| Monthly exports up to your usage | Full retail rate, netted on your bill | The PECO account holder |
| Monthly surplus beyond your usage | Carried forward as a kWh credit to next month | The PECO account holder |
| Year-end leftover at the annual true-up | PECO’s Price to Compare (supply rate, below full retail) | The PECO account holder |
| SRECs (one per 1,000 kWh produced) | A market price that moves | The system owner |
What is a PA SREC, and what is it worth in Fort Washington?
Pennsylvania pays solar owners a second time through the SREC market, on top of your bill savings. Under the state’s Alternative Energy Portfolio Standard, your system earns one Solar Renewable Energy Credit for every 1,000 kWh (one megawatt-hour) it generates, and you sell those credits to electricity suppliers who need them to meet Pennsylvania’s solar requirement (DSIRE Pennsylvania AEPS, as of 2026). A 6 kW Fort Washington roof making about 8,000 kWh a year earns roughly eight SRECs annually. Net metering lowers your bill; SRECs are a separate cash market on top of it.
PA SREC prices are market-based, and Pennsylvania protects its own market. Act 40 of 2017 largely closed Pennsylvania’s solar SREC market to new out-of-state systems, which was intended to strengthen the in-state market (PA PUC AEPS, as of 2026). Because the price floats with supply and demand, treat any single figure as a snapshot rather than a guarantee. For the current PA SREC price and how the trade works, see our Pennsylvania SREC price guide for 2026, and ask any installer whether they register and sell your SRECs for you or leave that to you.
The incentives that actually apply in Fort Washington (and the ones that do not)
Pennsylvania’s real homeowner incentives are net metering and SRECs, full stop. This matters because installer pages and search results often list incentives Pennsylvania does not actually offer. The table below sorts what applies to a Fort Washington home from what does not, so you can budget on facts rather than marketing.
| Program | Applies in Fort Washington? | What it does |
|---|---|---|
| PECO net metering | Yes | Full retail credit monthly up to usage; year-end excess at Price to Compare (52 Pa. Code 75.13) |
| PA SRECs (AEPS Tier I) | Yes | One credit per 1,000 kWh, sold on the market (DSIRE) |
| State solar income-tax credit | No | Pennsylvania has no state-level residential solar tax credit (PA DEP) |
| State solar sales-tax exemption | No | PA’s 6% sales tax generally applies to residential solar equipment; this is often overstated online (PA DEP) |
| Federal residential credit (Section 25D) | No, it ended | The 30% homeowner credit ended for systems placed in service after Dec 31, 2025 (IRS) |
What the end of the federal tax credit means for Fort Washington
The federal homeowner credit is gone, but Pennsylvania’s net metering and SRECs are not. The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a Fort Washington homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS Residential Clean Energy Credit, as of January 1, 2026). You will still find installer and contractor pages quoting the old 30% figure for 2026; the accurate answer is that the homeowner version already ended. What did not change is the part that drives the payback here: PECO net metering and the PA SREC market still apply. For the full timeline, see what the federal solar tax credit change means in 2026.
One federal exception exists, and it is not the homeowner’s to claim. Section 48E is a commercial clean-electricity credit claimed by the business that owns a system, such as the third-party owner of a leased or PPA installation, never by the resident living under the panels (IRS Clean Electricity Investment Credit, as of 2026). So on a lease or PPA you do not file for a federal credit yourself; the system owner does. If you buy your own rooftop system outright, there is no federal credit to claim in 2026, because 25D ended after December 31, 2025.
Permitting and local context in Upper Dublin Township
Most of Fort Washington sits in Upper Dublin Township, so your solar permit is a township process, not a borough one. Fort Washington is an unincorporated community, and most addresses are permitted through Upper Dublin Township’s Code Enforcement office, which handles building permits, with zoning questions going to the Township’s Community Planning and Zoning office (Upper Dublin Township, as of 2026). Some Fort Washington addresses fall in neighboring Whitemarsh Township instead, which runs its own Codes and Zoning office for building permits (Whitemarsh Township, as of 2026), so confirm which municipality your property is in before you file, since the permit office and rules differ. Either way the township applies standard building and fire-code rules for roof-mounted panels, including roof-access pathways and setbacks under the Uniform Construction Code, so an installer who has worked in your municipality will move your paperwork faster. This is a practical difference from nearby boroughs like Ambler, which run their own local permits.
Fort Washington has some visible solar leadership of its own. Fort Washington State Park is a net-zero park in the Pennsylvania State Parks system, where a 65 kW solar array offsets the park’s annual electricity use (Pennsylvania DCNR, as of 2026). It is a small local example of the same rooftop technology going on Upper Dublin homes. For your own home, the practical planning points are your township building permit, a PECO interconnection and Permission to Operate before the system switches on, and a shade check on tree-lined lots.
| Fort Washington or Upper Dublin factor | What to plan for |
|---|---|
| Township permit (Upper Dublin, or Whitemarsh for some addresses) | A township building permit plus zoning review, not a borough process; confirm your municipality and use an installer who knows it |
| Larger detached homes | Roofs here often carry an 8 kW to 10 kW system, so get a load and roof-structure check sized to the bigger array |
| PECO interconnection | PECO approval and Permission to Operate before the system produces; your installer files this |
| Mature trees and larger lots | A shade study; panel placement matters more than raw count on a shaded lot |
| SREC registration | Confirm whether your installer registers and sells your PA SRECs or leaves it to you |
Paying for solar in Fort Washington: cash, loan, lease, or PPA
How you pay decides who keeps the SRECs and whether you owe anything up front. There is no single right answer; it depends on whether you want to own the system and collect the SREC income yourself, or avoid an up-front cost. A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free solar, and the company that owns the panels keeps the SRECs while you get a lower or fixed power price. The net-metering bill credit still follows your PECO account either way.
| Path | Up-front cost | Who keeps the SRECs | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You, the owner | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You, the owner | You want ownership without paying cash up front |
| Lease or PPA | $0-up-front where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
How to choose a solar installer in Fort Washington
Montgomery County has a deep, competitive market of solar installers, which is good for you because it means real competition on price and service. Rather than chasing a “best installer” list, screen any company against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- A valid Pennsylvania Home Improvement Contractor (HIC) registration and proper electrical licensing.
- A clear workmanship and equipment warranty in writing.
- Real experience with PECO interconnection, Upper Dublin Township permitting, and PA SREC registration, so your paperwork and Permission to Operate go smoothly.
- A written production estimate and a transparent quote that counts net metering and SREC income honestly, and does not quote the federal credit that ended after December 31, 2025.

Frequently asked questions
Is solar worth it in Fort Washington, PA in 2026? For most owner-occupied Fort Washington homes with decent sun, yes. A typical 6 kW roof here produces about 8,021 kWh a year (NREL PVWatts, as of July 2026), and at Pennsylvania’s 20.92 cents per kWh rate (EIA, as of March 2026) that offsets roughly $1,680 a year on your PECO bill, for an estimated payback near 10 to 11 years before financing. PECO credits your exports at full retail through the year, and PA SRECs pay you on top. Savings are not guaranteed and depend on your roof, usage, and how you pay, but the combination of a solid rate, full-retail net metering, and larger local roofs makes Fort Washington a workable solar market.
Who is my electric utility for solar in Fort Washington? PECO. Fort Washington sits in PECO’s service territory in southeastern Pennsylvania, so your net metering and interconnection run through PECO (52 Pa. Code 75.13, as of 2026). That matters because the value of your solar depends on PECO’s specific rules: full retail credit month to month, surplus carried forward, and a year-end true-up at the Price to Compare. You can read the utility-level detail on our PECO net metering page, and the statewide rules on our Pennsylvania net metering guide.
Does Pennsylvania give away solar panels at no charge? No. Pennsylvania does not run a government program that hands homeowners panels at no charge, and no legitimate installer gives them away. What Pennsylvania does offer is net metering, which credits your exports, and the SREC market, which pays you for what you generate (DSIRE Pennsylvania AEPS, as of 2026). Some homeowners can go solar with no up-front cost through a lease or power purchase agreement where eligible, but that is a financing arrangement with monthly payments over 20 to 25 years, and solar panels are not free. Be cautious of any ad that promises panels for nothing.
How much does solar cost for a home in Fort Washington? Pennsylvania residential solar runs about $3.00 to $3.25 per watt installed before incentives (SolarReviews, 2025; EnergySage, 2025), so a 6 kW system is roughly $18,000 to $19,500 and a larger 10 kW system common on Fort Washington’s bigger roofs is roughly $30,000 to $32,500. At the 20.92 cents per kWh PA rate, the estimated payback lands around 10 to 11 years before financing, and PA SRECs shorten it. These are MySolarFY estimates on cited inputs, not a quote; your roof, usage, and financing change the number, so compare a written quote against the PVWatts calculator.
Does Pennsylvania have a solar tax credit or rebate? No. Pennsylvania has no statewide residential solar income-tax credit, no solar rebate, and no solar sales-tax exemption; the 6% state sales tax generally applies to a purchase (PA DEP Solar Resource Hub, as of 2026). What Pennsylvania does offer is net metering and the SREC market, which are the real homeowner benefits. The federal homeowner credit is not an option either, because Section 25D ended for systems placed in service after December 31, 2025 (IRS, as of January 1, 2026).
Do I need a special permit for solar in Fort Washington? You need a standard building permit plus a zoning review from your township. Most Fort Washington addresses fall in Upper Dublin Township, which permits through its Code Enforcement office, with zoning handled by Community Planning and Zoning (Upper Dublin Township, as of 2026). Some addresses sit in neighboring Whitemarsh Township instead, so confirm your municipality first, since the office and rules differ. Either township applies building and fire-code rules for roof-mounted panels, such as roof-access pathways and setbacks under the Uniform Construction Code. Your installer normally handles the permit application and the PECO interconnection paperwork, so hiring a company that has worked in your municipality speeds the process.
Can I get solar in Fort Washington with no up-front cost? Some homeowners can, through a lease or power purchase agreement (PPA) where eligible, which can mean no out-of-pocket cost at installation in exchange for monthly payments. This is not free solar; it is a long-term agreement, often 20 to 25 years, and total payments may exceed the cost of a cash purchase. On a lease or PPA the third-party owner, not you, keeps the SRECs and any owner-level credit, while your benefit is a lower or fixed power price. If you want to own the system and capture the SREC income yourself, a cash purchase or solar loan keeps those benefits with you. Check what you qualify for before deciding.
