Solar Agreements Explained: What Buyers and Sellers Need to Know

Solar panels are common across the Tri-Valley, and they can be a genuine value-add — but they can also complicate a transaction if the type of solar agreement isn't understood early. Not all solar systems are the same from a real estate standpoint, and the difference matters a great deal to both buyers and sellers.

The Three Main Types of Solar Arrangements

Owned systems (purchased outright or paid off). The homeowner bought the system, either with cash or through a loan that's since been paid off. There's no ongoing obligation attached to the panels, and they transfer with the home like any other fixture. This is generally the simplest scenario for a sale.

Solar loans (financed, not yet paid off). The homeowner owns the system but is still paying off a loan used to purchase it. Depending on the loan structure, this may show up as a lien on the property (sometimes called a PACE assessment, if financed through a property tax program) or as a separate personal loan. Either way, it typically needs to be addressed at closing — either paid off from sale proceeds or, in some cases, transferred to the buyer with their agreement.

Solar leases and Power Purchase Agreements (PPAs). In these arrangements, the homeowner doesn't own the panels at all — a solar company owns the system and either leases it to the homeowner for a fixed monthly fee (a lease) or sells them the power it generates at a set rate (a PPA). These agreements typically run 15-25 years and are not automatically owned by whoever owns the house — they require a formal transfer process to the buyer.

Why This Matters for Sellers

If your solar system is leased or under a PPA, you'll generally need to either:

• Transfer the agreement to the buyer, which usually requires the buyer to qualify (often a credit check) and formally assume the contract, or
• Pay off the remaining lease or PPA balance to remove the obligation before or at closing, or
• Have the system removed, which is typically the least common and most costly option

This process takes time — often several weeks — so it's important to identify the type of solar agreement on your home early, ideally before listing, so there are no surprises once you're in escrow with a buyer.

Why This Matters for Buyers

Before writing an offer on a home with solar, ask:

• Is the system owned, financed, or leased/PPA?
• If leased or a PPA, what are the remaining term, monthly cost, and any escalator clauses (some agreements include annual rate increases)?
• If financed, is there a lien against the property, and how will it be handled at closing?
• Will I need to qualify to assume the agreement, and what does that process involve?
• What happens if I want to remove the panels later (for a roof replacement, for example)?

A leased system with years remaining and a high monthly payment can meaningfully affect a home's overall cost of ownership — worth factoring into your offer and your budget, not just treating as a bonus amenity.

Documentation to Request

Whether buying or selling, it's worth gathering:

• The original solar agreement or loan documents
• Current account statements showing remaining balance or lease term
• Any transferability terms specific to that solar company
• Confirmation of whether a PACE assessment or UCC lien is attached to the property

The Bottom Line

Solar can be a genuine asset in a Tri-Valley home sale, but the type of agreement changes the entire process — and the math — for both sides of the transaction. If you're buying or selling a home with solar, I always make sure we identify exactly what kind of agreement is in place early, so it doesn't turn into a last-minute complication during escrow.
