Solar is the #1 closing-delay issue I see on Ventura County sales in 2026. About 25% of homes I list have solar of some kind, and about half of those are leased or PPA — which is where the trouble starts. The buyer's lender opens the file, the underwriter pulls the UCC-1 filing, and suddenly we have a 30-day delay while we figure out lease assumption, payoff, or removal. I'm Brian Cooper, REALTOR(R) at eXp Realty (DRE# 01434286). This is the 2026 read on solar, lease vs owned, NEM 3.0 export rates, and how to keep the deal on track.
Quick Answer
California homes with solar fall into three categories at sale. Owned panels (paid in cash or loan paid off): panels are real-property fixtures, transfer with the home automatically, and generally add value the way a remodeled kitchen does. Loan-financed panels (SunRun Loan, GoodLeap, Mosaic, others, still in repayment): the loan is secured by a UCC-1 fixture filing, must be paid off at closing through escrow, and the lender treats the unpaid balance as a closing-cost lien. PPA / lease (SunRun, Tesla, Sunnova, Trinity Solar): the panels are personal property of the solar company, the homeowner pays for the power produced, and the lease has to be transferred to the buyer, paid off, or removed before closing.
Fannie Mae Selling Guide B2-3-04 (Special Property Eligibility and Underwriting Considerations) directly addresses solar lease transfers and is the single most important document for navigating a California solar sale. Under NEM 3.0 (effective April 15, 2023), the value of net export compensation for new solar installations dropped approximately 75% versus NEM 2.0, which has cut the resale value of newly installed PV. Battery storage (Tesla Powerwall, LG Chem) becomes more important to value calculations under NEM 3.0. Appraisers use Sandia National Labs' PVValue tool and ANSI Z765 square-footage standards to add contributory value for owned PV.
Three solar models in California
Owned outright (cash or loan paid off). Homeowner owns the panels as real-property fixtures. No UCC-1 filing, no monthly payment, no third-party agreement. At sale, panels transfer automatically as part of the real property. Title insurance covers them. The appraiser adds contributory value. This is the cleanest scenario.
Loan-financed (still in repayment). Homeowner took out a solar loan (typically 12-25 years at 5-9%) to purchase panels. The loan is secured by a UCC-1 fixture filing on the panels. Major lenders: GoodLeap, Mosaic, Sunlight Financial, Dividend Finance, LightStream. At sale, the loan is paid off through escrow from sale proceeds, the UCC-1 is released, and the panels transfer free and clear. Treat the loan balance as a closing-cost item like a HELOC payoff.
Power Purchase Agreement (PPA) or lease. The solar company (SunRun, Tesla / SolarCity, Sunnova, Vivint Solar) owns the panels. The homeowner has a contract — typically 20 to 25 years — to pay either (a) per kWh produced (PPA) or (b) a fixed monthly lease. The homeowner does not own the panels. At sale, the lease has to be transferred to the buyer, paid off, the panels removed, or the lease assumption agreed to by all three parties (seller, buyer, solar company, plus buyer's lender).
Why leased panels block closings (FNMA B2-3-04)
Fannie Mae Selling Guide section B2-3-04 lays out the conventional-loan rules for properties with solar PPA / lease. Two requirements drive the closing friction.
First, the solar lease cannot be a lien on the real property. If the lease has a UCC-1 fixture filing, the lien must be terminated or subordinated before closing, or the buyer's lender will not fund. Most major PPA / lease providers do file UCC-1s. Subordination requests take 2-4 weeks to process. Termination requires lease payoff.
Second, the lease contract must be assumable by the buyer at no cost increase, and the buyer must meet the solar company's credit criteria. The buyer signs a transfer/assumption agreement with the solar company before closing. SunRun and Tesla have streamlined transfer processes; Sunnova and smaller providers can take 30-45 days.
If the buyer's lender is FHA, VA, or USDA, the rules are stricter — those agencies often require the lease to be paid off, not just transferred. This is one reason a leased-solar house can be harder to sell to a VA buyer than to a conventional-loan buyer.
The four closing options for leased solar
When I list a Simi Valley or Camarillo home with a solar lease, I work through these four options with the seller before going to market.
- Transfer the lease to the buyer. Solar company processes a credit check on buyer, both parties sign a transfer agreement, lease continues. Pros: zero out-of-pocket cost to seller. Cons: buyer pool shrinks (some buyers refuse to assume), can delay closing by 30-45 days, FHA/VA buyers often can't assume.
- Pay off the lease (seller buys it out). Seller pays the lease termination amount from sale proceeds at closing. The panels then transfer to the buyer as owned. Pros: simple, broadest buyer pool, removes the UCC-1. Cons: payoff amounts on early-stage leases can be $30K-$50K. Worse on year 2-3 leases than on year 18 leases.
- Buyer accepts lease assumption with credit added back. Negotiate: buyer assumes the lease and seller credits the buyer for the present-value cost of the lease at closing. Pros: keeps the deal moving, fairly priced. Cons: appraiser may not give value credit for the solar, so credit reduces seller proceeds.
- Remove the panels. Solar company de-installs panels and restores the roof. Pros: clean transfer of unencumbered real property. Cons: typically only available near end of lease term, removal costs $3K-$8K, roof restoration imperfect, panels can be removed but the rooftop holes remain.
Of the four, options 1 and 2 are the most common. Option 3 is the negotiation middle ground that saves a deal mid-escrow when the buyer's lender balks. Option 4 is rare and usually a last resort.
NEM 1.0 vs 2.0 vs 3.0: why new solar is worth less
California's Net Energy Metering (NEM) tariff is what determines how much credit a homeowner gets for solar energy exported back to the grid. NEM has gone through three major versions, and each cut the value to the homeowner.
NEM 1.0 (2006-2017 for SCE customers): full retail rate credit for exported power. Best case for homeowners. Locked in for 20 years from system interconnection. NEM 1.0 systems still earning retail credits today are the most valuable solar installations on California resale.
NEM 2.0 (2017-April 2023): retail credit minus non-bypassable charges (about $0.02-0.03 / kWh). Still very favorable. Most Ventura County rooftop solar installed 2017-2023 is NEM 2.0. NEM 2.0 rights last 20 years from interconnection and transfer with the property to the new owner.
NEM 3.0 (April 15, 2023 onward, now called the Net Billing Tariff): export compensation based on the avoided-cost calculator, which produces roughly 5-8 cents per kWh exported instead of the 30-40 cent retail rate. That is roughly a 75% cut. NEM 3.0 systems break even much more slowly — payback periods extended from 6-8 years to 9-12 years for systems without battery storage. Resale value of NEM 3.0 systems is materially lower than NEM 2.0 systems.
| Tariff | Effective dates | Export rate | Resale value signal |
|---|---|---|---|
| NEM 1.0 | Pre-2017 (SCE) | Full retail (~$0.30+) | Highest |
| NEM 2.0 | 2017-Apr 2023 | Retail minus NBC (~$0.27-0.34) | High |
| NEM 3.0 / NBT | Apr 15 2023+ | Avoided cost (~$0.05-0.08) | Lower; battery materially helps |
Battery storage: when it adds resale value
Under NEM 3.0, battery storage (Tesla Powerwall, LG Chem RESU, Enphase IQ Battery) becomes important to the value calculation. Without battery, daytime solar exports at the low avoided-cost rate and evening grid imports come at high retail rates. The spread destroys payback math.
With battery, daytime solar charges the battery, evening loads draw from the battery, and grid imports drop materially. Payback period compresses back to 7-10 years, and time-of-use rate arbitrage becomes possible.
For NEM 3.0 systems with battery, appraisers can add contributory value for both the PV and the storage. For NEM 3.0 systems without battery, contributory value can be near zero — buyers discount the system to almost the cost of removal.
For NEM 1.0 and 2.0 systems (pre-April 2023), battery is optional. The export economics are favorable enough that the system adds value with or without storage.
How appraisers value solar (PVValue + ANSI Z765)
Appraisers in California typically use Sandia National Labs' PVValue tool (an Excel-based calculator) to estimate the contributory value of an owned solar system. PVValue inputs the system size in kW DC, the year of installation, the applicable NEM tariff, the remaining warranty life, the local energy production estimate (from PVWatts), and local utility rates. Output is a dollar contributory value.
Typical PVValue results in Ventura County: a 6 kW owned NEM 2.0 system installed 2020 with full warranty: ~$14K-$18K contributory value. Same system as NEM 3.0 from 2024 with no battery: ~$5K-$9K. Same NEM 3.0 system plus a Powerwall: ~$15K-$20K.
ANSI Z765 is the square-footage standard appraisers follow. It does not directly value solar but it establishes the framework for above-grade vs below-grade and finished vs unfinished space. Solar is treated as a feature add-on, not a square-footage adjustment.
Leased solar gets ZERO contributory value from appraisers. The seller does not own the asset. Whatever monthly savings the lease provides accrue to the buyer who assumes the lease, not to a valuation adjustment. This is the key reason leased solar reduces total seller proceeds vs owned solar of the same size.
Specific provider notes: SunRun, Tesla, SolarCity
SunRun (largest residential solar lessor in CA). Has a streamlined transfer process via SunRun.com/sellingyourhome. Online transfer application, buyer credit check, 2-4 weeks to approve. Transfer fees are typically zero. UCC-1 subordination available on request with 2-3 week turn.
Tesla / former SolarCity. Lease and PPA transfers via Tesla Energy customer service. Slower than SunRun in 2024-2026 — expect 4-6 weeks for transfer approval. Payoff calculations are available on request from Tesla. SolarCity legacy contracts (pre-2016) have different transfer rules than current Tesla agreements; check the original contract.
Sunnova. Transfer process via Sunnova customer portal. 3-6 weeks typical. Some Sunnova contracts include escalator clauses raising payments 1-3% annually — confirm what the buyer is assuming.
Smaller / regional providers (Vivint Solar, Sungevity legacy, Trinity Solar). Variable. Pull the original contract early and call the provider the day the listing goes live.
SCE interconnection paperwork (PTO letter)
Permission to Operate (PTO) is the letter from Southern California Edison authorizing a solar system to interconnect with the grid. Every legitimate California rooftop solar installation has a PTO letter on file with the utility. Buyers' lenders increasingly request a copy of the PTO letter as part of underwriting.
If a homeowner installed solar without permits or without obtaining PTO (rare but it happens with older DIY installs or smaller contractors that went out of business), the system is technically operating illegally and the buyer's lender will decline to fund. Resolution requires applying for post-installation permits, inspection, and PTO — a 60-90 day process at a minimum.
Always confirm PTO letter availability before listing. Pull from the homeowner's email archive, from SCE's customer service, or from the original installer. If missing, address before going to market.
Disclosure obligations
Solar — owned or leased — must be disclosed on the Seller Property Questionnaire (SPQ) and the Transfer Disclosure Statement (TDS). Disclosure items include: type of system (owned, financed, PPA, lease), age and warranty, NEM tariff version, monthly lease or loan payment, remaining lease/loan term, transfer requirements, battery storage, and PTO letter status.
If there is an active solar loan, disclose the current payoff balance and the UCC-1 fixture filing. If PPA / lease, disclose the contract terms and the transfer/assumption process. California's anti-fraud disclosure statute (Civil Code 1102 et seq.) makes solar a material fact that has to be in writing.
Frequently Asked Questions
Should I pay off my solar loan before listing?
Usually yes, if you have the cash and the payoff isn't substantial. Paying off the loan removes the UCC-1, simplifies title, and lets you market the panels as owned. Adds appraisal value and opens the buyer pool. Run the math — sometimes a high-balance loan is better refinanced into the new buyer's mortgage.
Can a VA buyer assume my SunRun lease?
Sometimes, but not always. VA underwriting is stricter than conventional on solar leases. Many VA-backed loans require the lease to be paid off, not assumed. Check with the listing agent and the buyer's loan officer early. If the lease can't be assumed, you may need to negotiate a payoff.
What's the difference between a PPA and a lease?
A lease is a fixed monthly payment for the use of the panels. A PPA is a per-kWh payment for power produced. Economically they're similar but contract structures differ. PPAs may have rate escalators (often 2-3% per year). Leases may have buyout schedules. Read the specific agreement.
Does the solar tax credit transfer to the buyer?
No. The federal Residential Clean Energy Credit (IRC 25D, formerly the ITC) is claimed in the year of installation by the person who paid for the system. Once claimed, it does not transfer. The buyer cannot retroactively claim a credit on a system that's already been claimed.
What if the seller installed solar without permits?
Material disclosure problem. The home doesn't qualify for most conventional or VA financing until the system is permitted, inspected, and the PTO letter issued. Plan on a 60-90 day delay and several thousand dollars in remediation costs.
Are NEM 1.0 / 2.0 grandfathering rights transferable?
Yes. The grandfathered NEM tariff transfers with the property and applies through the 20-year grandfathering window. A NEM 2.0 system installed in 2020 has grandfathered rights through 2040, regardless of who owns the home.
How long does the average solar closing delay add?
When the lease transfer is identified early (before opening escrow), zero days. When discovered mid-escrow, typically 15-30 days. When a UCC-1 subordination is required, 14-30 days. Get ahead of it by pulling the lease agreement and calling the provider at listing.
Is battery storage required for new California solar?
Not legally required for residential rooftop. But under NEM 3.0, the economics are so much better with battery that most new installations include one. Battery storage is required for new construction homes under Title 24 mixed-use rules in some configurations.
