Solar panels are now present on a significant percentage of homes for sale in Southwest Riverside County. If you’re in escrow on a home with solar, or actively searching in neighborhoods with high solar density, there are several things worth understanding before you close — some of which can affect your financing, your insurance, and the economic value of the system you’re inheriting.
First: Is the System Owned or Leased?
This is the most consequential question. The answer changes almost everything else about how solar factors into the transaction.
If the system is owned outright by the seller, it transfers to you as part of the real property — like the roof or HVAC system. The seller should be able to provide the original purchase documentation, the permit and Permission to Operate letter from SCE, and any manufacturer warranty registration paperwork. Studies from Lawrence Berkeley National Laboratory consistently show that owned solar adds measurable value to home sale prices, averaging 3–4% in California markets.
If the system is leased or under a Power Purchase Agreement (PPA), you are not buying the panels — you’re assuming an ongoing contract. Leased systems require the buyer to qualify with the leasing company and formally assume the agreement. If the buyer doesn’t qualify, the seller may need to buy out the lease before closing. This is a common transaction complication in Riverside County right now, particularly with legacy SunPower and Sunrun contracts.
Your real estate agent and title company should identify the ownership structure early in escrow. A UCC-1 fixture filing on the property is a strong indicator that the system is financed or leased — it will appear in a title search.
What to Check on an Owned System
For an owned system, the key things to verify are:
Permits and interconnection: The system should have a building permit from the applicable jurisdiction and a Permission to Operate letter from SCE. An unpermitted solar system can create problems when you refinance, sell, or file an insurance claim. Ask the seller for these documents during due diligence. If they can’t produce them, that’s a red flag worth investigating before close.
Which NEM policy applies: If the system received Permission to Operate before April 15, 2023, it is grandfathered on NEM 2.0 — a significant financial asset worth preserving. The PTO date is on the SCE interconnection letter. Confirm this date and note it; you’ll want to protect the grandfathered status by maintaining continuous SCE service at the property.
System age and component condition: A 15-year-old system with original string inverters is not the same asset as a 5-year-old Enphase microinverter system. Inverters typically need replacement at 10–15 years, which is a cost you may be inheriting. A pre-purchase inspection quantifies the actual condition of the equipment and flags any components approaching end of life.
The Pre-Purchase Solar Inspection
A solar system inspection is not a standard part of a home inspection — most general home inspectors look at panels visually but don’t run diagnostics, read inverter error logs, or assess string performance. For a home with solar, we recommend a dedicated solar inspection separate from the general home inspection.
What a thorough solar inspection covers:
- Panel-level production verification via monitoring data (not just visual)
- Inverter diagnostic readout and error log review
- String testing and DC/AC output measurement
- Physical inspection of mounting hardware, roof penetrations, and conduit
- Review of permit documentation and interconnection paperwork
- NEM policy confirmation and estimated remaining grandfathered period
- Written report with findings and repair cost estimates where applicable
This report gives you leverage during negotiations if repairs are needed, documentation for your insurance provider, and a baseline for the system’s condition going forward.
Transferring Monitoring Access
This is the step most buyers miss until after close. Monitoring accounts are typically tied to the installer or original owner, not the property. When you take ownership of the home, you need to transfer or create your own monitoring account to have visibility into what your system is actually doing.
For Enphase systems, you initiate a homeowner account transfer through Enphase’s customer portal. For SolarEdge, the process is similar through the SolarEdge monitoring platform. In both cases, you’ll need the system’s serial numbers (on the inverter or gateway) and proof of current ownership.
If monitoring wasn’t set up properly by the previous owner, or if the installer’s account was the only access point and that installer is no longer in business, the monitoring device may need to be reconfigured on-site. This is something we handle regularly for new homeowners throughout Southwest Riverside County.
Assuming a Solar Lease: What to Know
If you’re proceeding with a leased system, ask the seller for the complete lease or PPA documentation before closing. Key things to understand:
- Monthly payment or per-kWh rate: Does the payment escalate annually? By how much? A 2.9% annual escalator over 20 years changes the financial picture significantly.
- Remaining term: How many years are left on the contract?
- Buyout option: Does the lease allow you to buy the system outright? At what price, and when?
- Maintenance responsibility: Most leases require the leasing company to maintain the system. Confirm this is actually happening — get documentation of any recent service visits.
A leased system isn’t inherently a problem, but it’s a financial obligation you’re assuming with specific terms. Understand those terms before you sign.
