Solar PPA Contracts in DC: Pros, Cons, and Who They Actually Make Sense For

A solar PPA in DC can cut your electricity bill with zero upfront cost — but the solar PPA DC pros cons math only works in your favor under specific conditions. In 2026, with the federal residential 25D Investment Tax Credit no longer available for purchased systems, third-party ownership models like PPAs have gotten more attention. That shift makes it worth being precise about what a PPA actually delivers, where it falls short, and which DC homeowners are genuinely better off signing one versus buying outright.

City Renewables installs purchased and financed solar systems across Washington, DC. We don't offer PPAs ourselves — which means we have no financial reason to steer you toward or away from them. This post draws on our direct experience quoting DC rooftops, our knowledge of DC-specific incentives, and the SEIA's updated residential consumer guide to give you a straight read on the PPA question.

What Is a Solar PPA?

A solar Power Purchase Agreement is a contract where a third-party company owns, installs, and maintains a solar system on your roof, and you agree to buy the electricity it produces at a set rate per kilowatt-hour. You never own the panels. The company owns the hardware, claims any available tax credits, and sells you the output — typically for 20 to 25 years. Your monthly payment varies with how much the system produces, unlike a lease where you pay a fixed amount regardless of output. The rate you pay per kWh is usually lower than your current Pepco rate at signing, which is where the savings pitch comes from. According to the SEIA Residential Consumer Guide to Solar Energy ↗, most PPA contracts include an annual escalator — typically 1% to 3% per year — that raises your per-kWh rate over the life of the agreement. That escalator is one of the most important numbers in the contract, and many homeowners miss it.

How Does a Solar PPA Work in DC?

In DC, a solar PPA works the same way it does nationally, but the local incentive structure changes the underlying economics significantly. The third-party company that owns your system is eligible to generate DC Solar Renewable Energy Certificates — SRECs — through the PJM-GATS registry. Each SREC represents 1,000 kWh of solar production. In 2026, DC SRECs are trading in the $360–$400 per MWh range, with a Solar Alternative Compliance Payment ceiling of $440. Under a PPA, those SRECs belong to the system owner, not you. On a typical DC rooftop system of 6 kW producing roughly 6,900 kWh per year — based on DC's average of about 1,150 kWh per installed kW — that's approximately 6.9 SRECs annually, worth $2,484 to $2,760 at current prices. You see none of that revenue. The PPA company does. That SREC transfer is the single biggest financial trade-off DC homeowners make when they choose a PPA over ownership. Our DC SREC guide walks through exactly how that revenue stream works for owners.

Solar PPA Pros: Where the Model Genuinely Helps

The strongest argument for a solar PPA is access — it lets households go solar without any upfront capital or credit qualification in some programs. The DC Solar Solution Program, for example, offers a PPA at $0 per kWh for 20 years, covers all property types including rentals with landlord approval, and requires no credit check. For a household that cannot qualify for a solar loan, cannot access the DC Sustainable Energy Utility's financing programs, or simply cannot tie up $10,000–$20,000 in a home improvement, a PPA removes the barrier entirely. Maintenance and repairs are the system owner's responsibility under most contracts, which eliminates the risk of a $2,000 inverter replacement landing on your plate in year 12. The system also comes with a production guarantee in most agreements — if output falls below a contracted threshold, the company owes you a credit. For renters or condo owners who want to reduce their electricity costs without a long-term ownership commitment, a PPA can be a workable path where ownership simply isn't available.

Solar PPA Cons and Problems You Should Know Before Signing

The core solar PPA problem is that you trade long-term financial upside for short-term convenience. In DC specifically, that trade is steeper than in most markets because of the SREC revenue you forfeit. Beyond the SREC issue, there are four practical problems that come up repeatedly.

Annual escalators add up. A 2% annual escalator on a starting rate of $0.10/kWh reaches $0.149/kWh by year 20. Pepco's residential rate has historically risen about 2–3% per year as well, so the hedge isn't as clean as it looks on paper.

Home sales get complicated. A 20-year PPA is a lien-like encumbrance on your property. When you sell, the buyer must either assume the contract or you must buy out the remaining term — sometimes at a cost that surprises sellers at closing. DC real estate agents report that PPA disclosures can slow transactions.

Roof access is constrained. If your roof needs repair or replacement during the PPA term, the system owner must remove and reinstall the panels. Contracts vary on who pays for that work. Read the clause carefully.

You cannot claim DC solar incentives as an owner. The Solar Advantage Plus program and SREC income both require system ownership. See our full breakdown of DC solar incentives in 2026 for what ownership unlocks.

Solar PPA vs. Buying: Side-by-Side Comparison

The 20-year SREC estimate assumes roughly 6.9 SRECs/year at a conservative $360/MWh, with DC's SREC market remaining active under the CleanEnergy DC Omnibus Amendment Act's Renewable Portfolio Standard requirements. Actual prices will vary.

Are Solar PPAs Worth It in DC?

For most DC homeowners who can qualify for a solar loan, a PPA is not worth it — the SREC revenue alone typically outweighs the convenience benefit within 5 to 7 years of ownership. A 6 kW system generating 6.9 SRECs per year at $380/MWh produces about $2,622 annually in SREC income that a PPA customer forfeits entirely. Over a 20-year contract, that's roughly $52,000 in foregone revenue before accounting for any escalation in SREC prices. Against a financed system where monthly loan payments often run $100–$160 and are offset by bill savings plus SREC income, ownership wins on total return in the vast majority of DC scenarios. The honest answer is that PPAs are worth it for a specific subset of DC households — those who cannot access ownership financing, live in a property where ownership isn't possible, or have a roof situation that makes the maintenance transfer genuinely valuable. For everyone else, the numbers favor buying. Run your own numbers using the Green Zone assessment before committing to either path.

Who a Solar PPA Actually Makes Sense For

A solar PPA makes the most financial sense for DC households in these situations:

1. You cannot qualify for a solar loan and have no cash to purchase. A PPA at $0/kWh still saves money versus Pepco rates, even without SREC income.
2. You're a renter with landlord approval and want to reduce your electricity costs without a long-term ownership stake in the property.
3. Your roof is aging and you don't want to own a system that may need to come down for a re-roof within 10 years. The PPA company handles removal and reinstallation under most contracts.
4. You own a condo or co-op where roof ownership is shared and individual system ownership isn't structurally possible.
5. You plan to sell within 3–5 years and a short-term bill reduction matters more than long-term asset building — though even here, the home sale complication is worth weighing carefully.

If none of those five conditions apply to you, the math in DC almost always favors ownership. The SREC market here is one of the strongest in the country, and forfeiting that income stream is a real cost, not a theoretical one.

What to Check Before Signing a DC Solar PPA Contract

If you've decided a PPA is the right path, these are the contract terms that matter most:

• Annual escalator rate. Get the exact percentage. Even 1% compounded over 20 years changes your total cost meaningfully.
• Buyout terms. What does it cost to purchase the system outright in years 5, 10, and 15? Some contracts offer a fair-market-value buyout; others set a fixed price that may or may not be favorable.
• Transfer process. How does the contract transfer if you sell your home? Who pays transfer fees? How long does the process take?
• Production guarantee. What is the guaranteed minimum output, and what credit do you receive if production falls short?
• Roof repair clause. Who pays for panel removal and reinstallation if your roof needs work? Get this in writing.
• SREC ownership. Confirm in writing that the system owner retains all SRECs. This is standard, but you should know it explicitly before signing.
• End-of-term options. At year 20 or 25, can you purchase the system, renew the agreement, or have the panels removed? What are the costs for each?

The SEIA Residential Consumer Guide ↗ has a full checklist of PPA contract terms worth reviewing before you sign anything.

Frequently Asked Questions

What are the disadvantages of a solar PPA?

The main disadvantages of a solar PPA are forfeited SREC income, annual rate escalators that increase your per-kWh cost over time, complications when selling your home, and no ownership of the asset at the end of the term. In DC specifically, the SREC forfeit is the largest financial disadvantage — a 6 kW system generates roughly $2,600/year in SREC revenue that goes to the system owner, not you.

Is a solar PPA worth it?

A solar PPA is worth it for DC homeowners who cannot qualify for a solar loan, are renters with landlord approval, or own a property where individual system ownership isn't possible. For homeowners who can finance a purchase, the 20-year financial outcome of ownership — including SREC income and asset value — typically exceeds the convenience benefit of a PPA by a significant margin.

What is a solar power purchase agreement?

A solar power purchase agreement (PPA) is a contract where a third-party company installs and owns a solar system on your property and sells you the electricity it produces at a fixed or escalating rate per kilowatt-hour. You pay for the power, not the panels. The system owner retains all tax benefits, SREC income, and ownership rights for the duration of the agreement, typically 20 to 25 years.

What happens to a solar PPA when you sell your house?

When you sell a house with a solar PPA, the contract must either be transferred to the new buyer or bought out by the seller. Transfer requires buyer approval and sometimes lender approval if the buyer is financing the purchase. Buyout costs vary by contract and remaining term. DC real estate agents report that PPA disclosures can slow or complicate closings, so disclose early in the sale process.

Who owns the SRECs in a solar PPA?

In a solar PPA, the system owner — the PPA company — owns all Solar Renewable Energy Certificates generated by the system. The homeowner has no claim to SREC income. In DC, where SRECs trade at $360–$400 per MWh in 2026, this is a meaningful annual revenue stream that PPA customers forfeit for the life of the agreement.

Can you buy out a solar PPA early?

Most solar PPA contracts include a buyout option, but the terms vary widely. Some contracts offer a fair-market-value purchase price at set intervals; others use a fixed schedule that may be above or below market. Read the buyout clause before signing. If the buyout price is reasonable, purchasing the system mid-contract can make sense — especially in DC, where SREC income makes ownership financially attractive.

---

The Bottom Line

A solar PPA removes the upfront cost barrier and the maintenance burden, and for some DC households those benefits are genuinely worth the trade-offs. But in a market with one of the strongest SREC programs in the country, forfeiting $2,500–$2,700 per year in SREC income is a real cost that most PPA comparisons understate. If you can own, own. If you can't, a PPA is still better than staying on Pepco.
