Across Southern California in 2023, thousands of homeowners signed contracts for rooftop solar systems they were promised would slash their electricity bills. Many of them are still waiting. Installation companies collected upfront payments and triggered third-party loan disbursements, then delivered systems that were never installed, never connected to the grid, or never turned on. In the meantime, the loans came due. Customers found themselves making monthly payments on financing for equipment that produced no power at all.
The pattern became severe enough that California regulators and consumer advocates flagged solar as one of the fastest-growing sources of consumer complaints in the state. The Contractors State License Board (CSLB), which licenses solar installers in California, and the state Department of Financial Protection and Innovation (DFPI) both reported rising volumes of grievances tied to residential solar sales and financing arrangements.
What Happened
The core failure was structural: the money moved before the work was done. Under most residential solar deals, a homeowner does not pay the installer directly out of pocket. Instead, they sign a long-term loan—often 20 or 25 years—through a third-party financing company. That lender pays the installer in stages, frequently releasing a large share of funds when a contract is signed or when panels are physically placed on the roof, not when the system is inspected, permitted, and generating electricity.
That gap created the opening. Some companies collected the loan proceeds and simply stalled. Panels sat on roofs for months without electrical connection, waiting on permits that were never filed or utility interconnection approvals that were never pursued. Others left projects half-finished when the business ran short of cash or shut down entirely. The homeowner, however, remained legally on the hook for the loan, because the financing contract was separate from the performance of the installer.

Why It Was Easy
Several features of the residential solar market made this kind of non-performance easy to pull off. First, the sales-to-installation pipeline is often fragmented: a door-to-door sales dealer, a separate installation crew, and a separate finance company may all be involved, with no single party accountable for the whole transaction. Homeowners frequently did not understand that their loan obligation was independent of whether the system ever worked.
Second, the loan disbursement schedule rewarded speed over completion. When lenders release funds at panel placement rather than at final inspection and 'permission to operate' from the utility, the installer has already been paid before the hardest and most failure-prone steps—permitting and interconnection—are done.
Third, oversight was thin relative to volume. California added rooftop solar at a record pace in the early 2020s, and enforcement bodies were outmatched. The CSLB can suspend or revoke licenses, but by the time complaints accumulate, the money is gone and the company may have dissolved. Aggregate losses to affected California homeowners have been estimated in the millions of dollars, with individual customers frequently carrying loans of $20,000 to $50,000 for dark systems.
What Investigators Found
Investigations and complaint reviews pointed less to a single mastermind than to a business model that externalized risk onto homeowners. Regulators found repeated instances of contracts where financing was locked in before any working system existed, misleading savings projections, and pressure sales tactics targeting older homeowners and non-English speakers. The DFPI and CSLB fielded hundreds of solar-related complaints, and consumer groups documented cases where customers could not reach installers, could not cancel loans, and could not get systems energized.
Enforcement responses included license actions against contractors and warnings to consumers to verify permits and licensing before signing. But recovery for individual homeowners often proved difficult once a company became insolvent or unresponsive—illustrating that after-the-fact enforcement rarely restores lost funds.
What Escrow Would Have Changed
The single change that would have prevented most of this harm is straightforward: hold the money in escrow and release it only against verified milestones. In an escrow-based structure, loan proceeds and customer payments sit with a neutral third party rather than flowing to the installer at contract signing or panel drop.
Funds would be released in stages tied to independently confirmable events—permits filed and approved, installation inspected and passed, and critically, 'permission to operate' issued by the utility confirming the system is connected and generating power. Under such a model, an installer who placed dead panels on a roof and walked away would never receive the final and largest tranche, because the milestone that unlocks it—a working, energized system—was never met.
Escrow also protects the homeowner if a company collapses mid-project. Undisbursed funds remain available to hire another contractor to finish the job, rather than vanishing into a defunct business. And by decoupling payment from mere possession of equipment, escrow removes the incentive to prioritize signings over completions. The California failures were not primarily a technology problem or even a fraud-detection problem; they were a timing problem. Money that changed hands before value was delivered is money that could not be clawed back. A structural hold on those funds converts a broken promise into a simple withheld payment.
