What happened to Vivint Solar?

Vivint Solar didn't go out of business — it was acquired. Sunrun completed an all-stock purchase of Vivint Solar on October 8, 2020, in a deal that valued the company at roughly $3.2 billion, and the Vivint Solar brand was retired into Sunrun. If you signed with Vivint Solar between 2011 and 2020, your contract is now held by Sunrun, and vivintsolar.com simply redirects to sunrun.com.

Vivint Solar was a big deal here: about 36% of everything it installed nationwide was in California, and it ran a branch right in Miramar. Thousands of San Diego roofs carry its systems — typically Enphase microinverters in the early years, SolarEdge inverters from 2015 on, under panels from makers like Canadian Solar, Trina, and Jinko.

The first question: do you actually own your system?

This is the fork in the road, and many homeowners have never been told which side they're on. In Vivint Solar's own 2019 filings, roughly 83% of what it installed that year was under a power purchase agreement or lease — meaning the company, not the homeowner, owns the equipment on the roof. Only about 17% were customer purchases, a share that grew after Vivint began offering loans and cash sales in late 2016.

If you lease or have a PPA: Sunrun owns your system, and Sunrun is contractually responsible for maintaining it. Their existing-customer line is (855) 478-6786, plus the app your Vivint account rolled into. Be persistent: Sunrun's BBB profile shows more than 4,000 complaints closed in the last three years, with service and repair issues the largest category, and several state attorneys general have taken action over service and sales practices — Arizona's 2025 consent agreement explicitly covers legacy Vivint Solar customers. Document every outage and every call; if your system is down, you may be entitled to remedies under your agreement.

If you own it — bought outright or financed with a loan — no one is obligated to maintain it for you, and that's where a local contractor comes in.

What we do for Vivint-era systems in San Diego

For owned systems, we're a full-service shop:

• A $399 solar system and roof inspection report — credited toward your job — production audit, wiring and connector inspection, and a look at every roof penetration, with the findings in writing.
• Diagnostics and repair under an active C-10 electrical license — failed microinverters, optimizers, arc faults, rapid-shutdown issues, and the manufacturer warranty claims that go with them. Enphase and SolarEdge — the brands on most Vivint-era roofs — are healthy, operating companies, and in many cases we can replace failed equipment at no cost to you under the manufacturer's warranty. Our inspection report tells us whether you qualify.
• Monitoring restoration — getting your Enphase or SolarEdge portal registered under your own name.
• Battery retrofits — adding storage sized for NEM 3.0 economics.

For leased systems, we stay in our lane — the equipment is Sunrun's, and only Sunrun can work on it. But the roof underneath is yours. If your roof needs repair or replacement under a leased array, we handle the roofing side and help you navigate Sunrun's detach-and-reset process so the two projects don't turn into finger-pointing. (See: reroofing under existing solar.)

Estimates are always free. One company, one license set — B, C-10, and C-39 — CSLB #1130793. Call (858) 541-1097.

Why this is worth an hour of your attention now

Vivint-era systems are now 6 to 15 years old — the age when microinverters and optimizers start failing and roof penetrations start telling you how well they were flashed. If your monitoring went dark somewhere in the shuffle to Sunrun, your system could be underproducing right now and nobody would know. A one-visit inspection tells you whether the system is earning its keep, whether warranty claims should be filed while parts and serial records are easy to match, and whether the roof under the array is sound — and the $399 report is credited in full toward any work you hire us for.
