Why it matters
A solar company bankruptcy or restructuring may involve sales that change who owns, services, or administers customer agreements.

Why it matters
A buyout may be considered when a transfer is not available, when a buyer will not assume the agreement, or when closing requires resolution.

Why it matters
A balloon payment can affect payoff decisions, buyer expectations, and the true cost of keeping or transferring a solar obligation.

Why it matters
Customers may need to determine who now owns or services their agreement and where to request payoff or transfer information.

A condition in a real estate transaction that must be satisfied or addressed before closing obligations become final.
Why it matters
A solar payoff, assumption, approval, title issue, or document review can become a contingency if the parties make it part of the transaction.
D

A cost sometimes embedded in solar financing that can affect the contract price or loan economics.
Why it matters
Dealer fees may influence payoff amounts, comparisons between cash and financed pricing, and customer understanding of total cost.

Why it matters
Default language can affect fees, acceleration, remedies, transfer rights, and what must be resolved before or after closing.
E
Executory contract
A contract under which material obligations remain on both sides; bankruptcy treatment can include assumption, assignment, or rejection.

Why it matters

Why it matters
A lease may need to be transferred, assumed, bought out, or addressed before a home sale closes.

Why it matters
A lien or similar recorded interest can affect title review, lender approval, payoff requirements, and closing conditions.

Why it matters

A charge that may apply when transferring, assigning, or processing a solar agreement during a sale or assumption.
Why it matters
Transfer fees can affect closing costs, negotiations, and the timing of approval paperwork.

Why it matters
Fixture filings may appear during title review and can create additional closing or lender requirements.

Workmanship warranty
Coverage for installation-related defects, typically provided by the installer.
Why it matters

Common Questions About Solar Transaction Terms
Is a UCC filing the same as a lien on my house?+
Not always. A UCC filing often relates to a creditor’s claimed interest in personal property, such as solar equipment. A fixture filing or other recorded item may still matter during title or lender review, so it should be evaluated in context by qualified professionals.
Is the loan servicer always the company that owns my loan?+
No. The servicer may handle statements, payments, payoff requests, and customer service while a different entity owns the debt or controls certain approvals.
Can a solar loan delay a home closing?+
Yes, it can. A payoff, buyer assumption, UCC filing, subordination, title question, or missing transfer approval can create timing issues if it is not addressed early.
What happens to my solar agreement if the company files Chapter 11?+
The answer depends on the bankruptcy case and the agreement. A company may keep operating, transfer servicing, sell assets, assume or assign contracts, or change support processes under court supervision.
Can a solar lease or power purchase agreement transfer to a buyer?+
Many agreements include a transfer or assumption process, but requirements vary. Buyers may need approval, forms, signatures, credit review, or written confirmation before closing.
What is the difference between a solar loan, lease, and power purchase agreement?+
A solar loan usually finances ownership of the system. A lease usually means a third party owns the equipment and the homeowner pays to use it. A power purchase agreement usually charges for electricity produced by the system.
Why would a mortgage lender require subordination?+
A mortgage lender may want confirmation that another creditor’s interest has lower priority than the mortgage before approving a purchase loan or refinance.
What should I request before selling a home with solar?+
Request the solar agreement, payoff or assumption requirements, current servicer contact information, transfer forms, UCC or title-related documents, warranty information, and written confirmation of any approval needed before closing.
