ADT Solar Customer? The Installer Left. We Did Not.

ADT — the security giant — announced its exit from the residential solar business in January 2024, winding down the operation it had built after acquiring Sunpro. ADT the company is very much alive; ADT Solar as your installer is not. If they put the system on your Arizona roof, here is what that means and what to do.

ADT Solar installs were heavily Enphase-based — we are Enphase-certified
Equipment warranties survive; the installer warranty and service line do not
$199 diagnostic · $299 written inspection · SolarCare for the long term
Phoenix metro and Tucson, six in-house W2 crews

The strange case of an installer that left while the company stayed

Solar technician verifying a residential array in the Arizona desert — The hardware ADT installed was mostly first-rate. It just needs a new responsible party.

ADT’s solar exit was orderly by industry standards — announced in January 2024, wound down over the months that followed — but the end state for homeowners is the same as any installer closure: the entity that warranted your installation stopped doing installations, the service line went away, and questions about the roof penetrations, the racking and the workmanship now land nowhere. The good news is what ADT actually installed: predominantly Enphase microinverter systems with tier-one panels — equipment with strong, surviving manufacturer warranties (Enphase micros carry 25 years) and no proprietary lock-in.

That makes ADT systems some of the most straightforward orphans we adopt: we are Enphase-certified, the per-panel microinverter architecture makes faults precisely diagnosable, and warranty claims on covered hardware are a well-worn path for our Service Department.

Repairs we make carry our warranty — theirs is gone, ours is not

We are a licensed Arizona electrical contractor (ROC #331356), certified by Tesla, Sunrun, SunPower, SMA, SolarEdge, Enphase and APS. Work we do carries our 10-year workmanship warranty covering every nut, bolt and electrical connection we touch — so your system has a live warranty again, no matter what happened to the company that installed it.

Four steps for ADT Solar customers, in order

Gather your paperwork. Contract, permits, interconnection approval, serial numbers, warranty registrations, monitoring logins. If ADT Solar never registered your equipment with the manufacturer, the documents you hold are how coverage gets established.
Confirm the system is producing. Check the monitoring app against old utility bills. Orphaned systems commonly run degraded for months because nobody is watching.
Get the condition on paper. A $299 inspection gives you a licensed contractor’s written record — the document every warranty claim, home sale or dispute starts from. Selling or in a dispute? The $500 tier adds a documented valuation.
Give the system a new home for service. A one-off repair or the SolarCare Plan ($500/yr, two full visits) — either way, someone is responsible for it again.

Worth knowing for ADT installs specifically

One dead microinverter hides easily. Enphase systems lose one panel at a time, not the whole array — which means a failure can sit unnoticed for a year, quietly costing production. Twice-a-year verification (or the Enphase app, checked monthly) catches it.
Financed through ADT or a partner lender? Your loan is unaffected by the exit — keep paying — and unlike a lease, you own the system outright, which makes service, upgrades and home-sale documentation simpler.

Questions we hear from adt solar customers

The installation workmanship warranty effectively went with ADT Solar’s wind-down. The equipment warranties survive — and ADT installed mostly Enphase-based systems, whose microinverters carry 25-year manufacturer warranties. We are Enphase-certified and process those claims; you pay labor, the manufacturer covers covered hardware.

Any licensed, certified solar service company — you were never contractually tied to ADT for service. We service ADT/Sunpro-era systems across Phoenix metro and Tucson with our own W2 technicians, and our repairs carry our 10-year workmanship warranty.

Yes — one dead microinverter is the classic Enphase failure, it will not fix itself, and it is often a warranty part. The $199 diagnostic confirms it and the claim; you pay the visit and swap labor, not the hardware.

No — the security business and the wound-down solar business are separate. Your security contract continues; solar service needs a new provider regardless.

Get one written baseline. Nobody has been responsible for the system since the exit; a $299 inspection documents production, penetrations and connections once — and the SolarCare Plan keeps it that way for $500/yr.
