How Big the Solar-Orphan Population Got
A “solar orphan” is a homeowner with a working system whose original installer no longer exists to service it, and the population behind that description grew fast between 2024 and 2026. Titan Solar Power, a top 10 residential installer, filed Chapter 7 on June 13, 2024. SunPower Corp filed Chapter 11 in August 2024, selling its dealer network and Blue Raven Solar brand to Complete Solaria for $45 million. Sunnova filed Chapter 11 in June 2025. PosiGen, which had served 40,000 customers across 15 states, ceased most operations in August 2025 and filed Chapter 11 on November 24, 2025. Freedom Forever, the #2 US residential installer with roughly 6.1% market share, filed Chapter 11 on April 15, 2026, with $500 million to $1 billion in liabilities. Each of those filings left behind homeowners whose panels still work and whose original installer relationship did not survive.
The Open Question the Industry Itself Hasn’t Answered
This is not a hypothetical gap. SolarReviews’ own comprehensive warranty guide states plainly that “in August 2024, SunPower filed for bankruptcy, leaving questions about how SunPower warranties will be honored moving forward,” a named, independent industry publisher flagging the exact uncertainty this guide is built to address, for the exact bankruptcy event this vertical already tracks closely. If a publisher covering the industry professionally cannot give a clean answer for SunPower specifically, no rep should be improvising one for a homeowner on the spot either.

Book a Solar CallWhy “Orphan” Is a Real Status, Not a Marketing Label
A solar installation carries two separate types of warranty coverage, and only one of them survives an installer’s closure automatically. A performance and product warranty is the panel or inverter manufacturer’s own obligation, typically running 25 years, and it does not depend on the original installer still existing. A workmanship warranty, covering the quality of the physical installation itself, mounting, wiring, roof-penetration sealing, is the installer’s own obligation, not the manufacturer’s, and it does not survive the installer’s closure in any meaningful way. A homeowner whose installer went bankrupt has lost real, specific coverage, the workmanship warranty, even if their panels’ manufacturer warranty technically remains valid on paper. That is what makes “orphan” an accurate description rather than a sales euphemism.
What This Means as an Appointment-Generating Segment
A homeowner who learns their original installer is gone has a genuine, unresolved need: someone to confirm what coverage they actually still have, handle a service issue if one comes up, and answer the warranty-transfer question SolarReviews itself says is still open for at least one major 2024 bankruptcy. That is a real conversation, not a manufactured one, and it is a segment that grows every time another installer files, not one that competes directly against the shrinking first-install pool covered elsewhere on this site. Identifying which specific homeowners fit this profile, by installation year and original installer, is its own methodology, covered separately.
