Lumio
Is Lumio Solar still in business? What happened, and who handles your system now
Updated October 19, 2026.
No. Lumio, the Lehi, Utah door-to-door solar company, filed Chapter 11 in Delaware on September 3, 2024. It was sold as a reorganization and ended as a liquidation: the court approved a sale of nearly all its assets to Zeo Energy on November 1, 2024, the plan went effective on February 18, 2025, and a liquidation trustee now holds what is left.
What that means for you
- Now a claim: Lumio's workmanship warranty and any production guarantee in your contract are now claims against the liquidation trust.
- Still yours: the hardware. Lumio installed other companies' panels and inverters, and those makers warrant their own equipment for 10 to 25 years, whether or not Lumio exists.
- Still running: your monitoring app in most cases, because it belongs to the inverter maker, and your loan or lease, which a lender made and someone still services.
Who is responsible now
You own it (cash or a loan): the panel and inverter makers' warranties are yours and outlive the installer. The lender is a separate company from the repair, and the loan keeps going.
A lease or a PPA: the company that owns the system and bills you is responsible for it under your agreement, even if it took over from the company you signed with.
Why it stalls, and what gets an answer
Owners call the old Lumio number, then the lender, then the inverter maker, and each one points somewhere else. What gets an answer is one dated letter to the right company, with your serial numbers or account, what is wrong, since when, and a date to answer in writing. More on Lumio: the full Lumio page. If your system is down, see my solar company went out of business and my system is down and my inverter failed.
The letter that gets a written answer. I write it for you from your own agreement, bills and production numbers: to the equipment maker if you own the system, or to the company that bills you if it's a lease or a PPA. It puts the facts on the record and asks for a written answer by a date. If no written answer comes within 30 days, the follow-up letter is free.

“After the letter was sent, it was mere days that they got back to me with a much more positive email looking into all our issues causing the total system to be down.”

What happened next: after her letter, SunStrong answered in writing within days, saying it would put billing and collections on hold, cancel auto-pay and set up a deferment while it looks into the system. See page 1 of her letter.
What this page isn't
It isn't legal advice. Agreements and state rules differ, and your own agreement wins over anything general here. I prepare documents at your direction; you review, sign and send them yourself.
