How owned, leased, and PPA solar shapes value, financing, and net metering across Marin and San Francisco. From Marks Realty Group, Compass, Marin County.
Spend a clear afternoon walking a street in Mill Valley, Novato, or the Sunset, and you will count more rooftop solar than you would have a few years ago. The panels catch the eye, and most buyers assume they are simply a feature, something in the same category as a renovated kitchen or a newer roof. In our experience, that is exactly where a quiet question hides, one almost nobody asks until there is a contract on the table. Who actually owns the panels, and what happens to them when the home changes hands.
We hear a version of it from both sides of nearly every deal. Sellers ask whether the system on their roof helps or complicates the sale, and buyers ask what they are stepping into when they buy a home with leased solar panels already installed. More than two million rooftop solar systems are now installed across California, according to the California Solar and Storage Association, so this is not a niche concern. It is a normal part of selling a house with solar in the Bay Area, and it almost always comes down to one word that never comes up at the open house. Ownership.
The Panel Is Easy. The Paperwork Is the Deal.
Solar on a roof falls into a few groups, and they behave very differently in a sale. Owned panels were bought outright, with cash or a loan that is now paid off, and they belong to the home. Financed panels were bought with a loan that is still outstanding, often secured by the equipment itself. Leased panels and power purchase agreements, or PPAs, mean a solar company owns the system while the homeowner pays either a monthly amount or a set rate for the power it produces.
The reason we ask for the documents before we ever talk about price is that these are not small distinctions. A buyer stepping into an owned system is in a completely different position from one being asked to qualify for and take over the remaining years of someone else’s lease. The paperwork tells us which of those two conversations we are actually about to have.
The Marks Realty Group View: Settle the Panels Before You List
We give every seller with panels the same piece of advice, and it rarely changes. Find the agreement, read it, and know exactly what you own before the first showing, not during the final week of escrow. The friction we see almost never comes from the panels themselves. It comes from a lease nobody located until a buyer was already emotionally committed, when a clean deal suddenly grows a new moving part at the worst possible moment.
Our view is that solar belongs in the same category as any other material fact about a home. Handled early and disclosed plainly, an owned system can be a real asset, and even a leased one is rarely a dealbreaker. Left to surface on its own, any of it can unsettle a buyer who feels they were not told the whole story. Transparency is not just a compliance box for us. It is how cleaner offers get written.
What Owned and Leased Panels Do to the Appraisal and the Loan
This is where ownership stops being a technicality and starts affecting money. According to Fannie Mae’s Selling Guide, owned panels can be counted in a home’s appraised value under standard requirements. Leased and PPA systems are treated as personal property, cannot be added to the appraised value, and the lender has to confirm the solar company’s interest does not sit ahead of the mortgage in line.
We will be honest about the value question, because the industry is. Studies on exactly how much owned solar adds vary, and an appraiser’s figure depends on the system, the roof, and the local buyer pool, so we never promise a seller a fixed premium. What we will say plainly is this. Owned solar can help a home appraise and finance cleanly. Leased solar adds no appraised value and needs its paperwork reviewed early so it does not slow the buyer’s loan.
The Net Metering Terms a Buyer Quietly Inherits
Here is the detail many owners do not realize is sitting on their roof. California moved to a less generous net billing structure, often called NEM 3.0, for customers who submitted an interconnection application on or after April 15, 2023, according to the California Public Utilities Commission. Systems whose application went in before that date keep their older and more favorable net metering terms for twenty years from the date the system was connected to the grid.
The part that matters in a sale is that those legacy terms stay with the home rather than the person. A 2025 state bill that would have ended the benefit when a property changed hands was amended to remove that provision, so under current rules a buyer still inherits the seller’s original agreement for whatever years remain. On an older system that can be worth real money each year, and for the right buyer it is a feature we make sure gets understood rather than overlooked.
Why This Comes Up So Often on Marin and San Francisco Roofs
There is a reason our market sees this more than most. California has required solar on most newly built homes since 2020, under the state’s Title 24 building energy code, according to the California Energy Commission, so newer construction across San Rafael and Novato often arrives with a system already in place, sometimes owned and sometimes carried by the builder’s provider. Older homes across Southern Marin and San Francisco, meanwhile, had panels added over the years in every arrangement imaginable.
The local wrinkles are real. On a hillside home in Mill Valley or Tiburon, panels sit on a roof that may need replacing before a sale, and removing and resetting an array adds cost and coordination. In the higher fire risk parts of the county, where roof condition and insurance already shape the buyer pool, solar is one more item an underwriter and an inspector will study closely. Even orientation matters here, since a system on a fog belt roof in the outer Sunset produces differently from one in sun soaked Novato. None of this is a reason to walk away from a home with solar. It is a reason to look at the specific system on the specific roof, which is exactly what we do.
Common Questions We Hear About Homes With Solar
Do solar panels add value to a home? Owned panels can, and Fannie Mae allows them to be counted in the appraisal under standard rules. Leased and PPA panels do not add appraised value, because a third party owns the equipment.
Can you sell a house with leased solar panels? Yes, and we do it regularly. The lease is handled one of three ways. The buyer qualifies and assumes it, the seller buys it out so the panels convey free and clear, or the two sides negotiate a credit.
What happens to net metering when I buy a home with solar? Under current California rules, you inherit the seller’s existing net metering agreement, including the more favorable legacy terms on systems whose interconnection application was submitted before April 15, 2023.
Are leased solar panels a dealbreaker? Rarely. Handled early, they are a manageable part of the transaction. Left undiscovered until closing, they can slow a deal that was otherwise clean.
Key Takeaways for Bay Area Buyers and Sellers
Ownership is the first thing to establish, because owned, financed, leased, and PPA systems each behave differently in a sale.
Owned solar can add appraised value and finance cleanly, while leased and PPA systems add no appraised value and need their paperwork reviewed early.
A buyer inherits the seller’s net metering agreement, and the legacy terms on systems that applied before April 2023 can be worth real money.
Newer Bay Area construction often arrives with solar already installed, thanks to California’s building code, so the arrangement varies from home to home.
Sellers who gather their solar documents before listing tend to write cleaner deals, and buyers who ask the right questions avoid surprises.
Looking Ahead: Solar as a Normal Part of the Sale
Solar has moved from novelty to normal on Bay Area roofs, and it deserves to be treated that way inside a transaction rather than as a surprise at the end of one. Handled early, panels rarely derail a deal, and an owned system with strong legacy net metering can genuinely strengthen one. The homes that trade smoothly are almost always the ones where someone asked the right questions on day one.
If a move is on your horizon and there are panels on the roof, yours or the one you hope to buy, we would welcome the chance to look at the actual system, the actual paperwork, and what it means for your specific home in Marin or San Francisco, well before any of it becomes a last minute problem.
