The short answer

When the house you are buying has solar, check two things: the paperwork and the hardware.

The paperwork tells you whether the system is owned, leased or financed, whether a lien is recorded, and whether it was permitted and approved by the utility.

The hardware check confirms it works and the roof beneath it is sound.

Before closing on a solar home

Owned, leased or financed?

Each means something different for you.

Liens show up in title

A UCC-1 filing can delay closing.

Permit and PTO

Unpermitted systems are a problem you inherit.

The paperwork to request

Ask the seller for these before your inspection contingency ends.

Ownership proof

Purchase contract, loan or lease agreement.

Lien status

Any UCC-1 fixture filing; see solar UCC-1 liens.

Permit and PTO letter

From the city and the utility.

Warranties

Product and workmanship, and whether they transfer.

Production history

A year of monitoring or bills.

If the system is leased

You will either take over the lease or ask the seller to buy it out. The lease company must approve the transfer, often with a credit check. Read transferring a solar lease and our guide to buying a house with solar.

Questions

Does a home inspector check solar panels?
Many look only from the ground. Ask whether they test the system or hire a solar technician for that.
Can I refuse to take over a solar lease?
You can make the purchase conditional on the seller buying out the lease. See selling a home with leased solar.
Does solar raise a home’s value?
Owned systems often add value; leased ones are more complicated. See solar and home value.

Primary-source research, data analysis and fact checking

We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.

Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.
