ADT Solar Shut Down: Who Services ADT Solar and Sunpro Systems in California Now?

If you have solar panels installed by ADT Solar (formerly Sunpro Solar) on your Southern California home, the installer that put them there no longer operates in California. ADT Solar's California contractor license expired August 31, 2025 — more than a year after the company wound down field operations — and was independently verified as inactive in January 2026. That means for any service need today, you need a different, currently licensed contractor.

Last verified: October 2026 by Helios Energy Global.

What happened to ADT Solar, and when?

On January 19, 2024, ADT Inc.'s board of directors approved a plan to fully exit the residential solar business, after a strategic review and continued macroeconomic and industry pressures. The announcement followed a November 2023 branch-closure round that had already cut a significant portion of the solar operation.

ADT had entered the solar business in 2021 by acquiring installer Sunpro, spending $160 million in cash and 77 million shares of ADT stock — implying an enterprise value of around $825 million.

Sunpro was rebranded to ADT Solar. The combined entity operated in more than 20 states, including California, before the exit.

As of June 30, 2024, substantially all operations of the solar business had ceased, with results classified as discontinued operations in ADT's consolidated financial statements.

ADT's announcement said the exit "may include the transfer of components of the business to other parties" — but this was a corporate decision, not a bankruptcy filing. ADT Inc. the security company remains in business and solvent; only the solar division is gone.

ADT Solar's California contractor license: what the CSLB record shows

ADT Solar LLC held California contractor license #1080382. According to the BuildZoom record cross-referenced against CSLB data, ADT Solar LLC held a Solar Contractor license (#1080382) with an expiration date of August 31, 2025, and the license was last verified expired on January 12, 2026. No active California license for ADT Solar LLC or its predecessor Sunpro Solar appears in the current CSLB database. In plain terms: ADT Solar is not authorized to perform licensed construction work in California today, and has not been since at least late 2025.

This matters practically. Do not use a contractor who is not licensed to perform solar work. If anyone contacts you claiming to service your ADT Solar system under that license, verify their current CSLB status at cslb.ca.gov before letting them on your roof.

What ADT has said about warranties for existing customers

ADT has not been silent about existing customers, but its public statements have been general. ADT has publicly stated that it will stand behind existing installations, saying "ADT stands behind the products we sell and our work," and its support page confirms that while no new solar customers are being accepted, the company continues to provide support for existing solar customers.

ADT has assured customers it will honor its 25-year limited Workmanship Warranty and 25-year Power Production Guarantee, and manufacturer warranties for panels, inverters, and mounting systems also remain unchanged — however, customers have reported delays in service and difficulty reaching support.

There are documented reports from homeowners of warranty terms being disputed or changed after ADT took over Sunpro, with some customers saying coverage they were originally promised was later denied. This isn't a universal outcome, and ADT's official position is that warranties will be honored — but it's worth knowing these disputes exist.

Bottom line: Get any warranty claim confirmation from ADT in writing before scheduling service. If ADT's support line does not respond, escalate through the California Department of Consumer Affairs or file a complaint with the BBB — even wound-down companies like ADT Solar still answer BBB complaints when they ignore everything else.

Which warranties survive — and which ones don't

This is the most important table for ADT Solar and Sunpro owners in California.

Warranty type	Who backed it	Survives ADT Solar exit?	What to do now
Panel product warranty (materials, defects)	Panel manufacturer (e.g., LG, Q CELLS)	Yes — manufacturer is independent	Find model/serial on panel; contact manufacturer directly
Panel power output warranty	Panel manufacturer	Yes — independent	Same as above
Microinverter warranty (Enphase IQ7/IQ8)	Enphase Energy	Yes — 25 years from installation	Contact Enphase at enphaseenergy.com; have serial numbers ready
String inverter warranty (SolarEdge, etc.)	Inverter manufacturer	Varies — 12 years base	Contact manufacturer; check if extended warranty was purchased
Workmanship / labor warranty	ADT Solar (installer)	Uncertain — ADT claims it will honor; real-world results vary	Contact ADT support in writing; document everything
Power production guarantee	ADT Solar	Uncertain — same as above	Same; keep original contract
Monitoring platform	Enphase Enlighten or SolarEdge	Yes — independent of installer	Log in directly; contact manufacturer if credentials are lost
Roof penetration / leak warranty	ADT Solar	Uncertain — installer-dependent	If ADT won't respond, consult a licensed roofing contractor

Your installer's workmanship warranty is usually gone when an installer exits, but your equipment manufacturer's warranty, your monitoring, and your financing are held by different companies that are almost always still in business — those are three separate contracts with three separate parties, and only one of them failed.

Many string inverters carry base terms around 10 to 12 years, while current Enphase IQ microinverters carry 25-year limited warranties. If your Sunpro or ADT Solar system used Enphase microinverters — which was common — that warranty runs directly with Enphase, not with ADT Solar. If you experience a defect, Enphase will inspect and confirm coverage; if covered, the company will repair or replace the product free of charge or provide a refund — however, Enphase does not cover the labor charges involved with uninstalling or reinstalling the microinverter(s) in case of a claimed warranty. You'll need a licensed California contractor to do the physical swap work.

Who to call for each service need in Southern California

Monitoring is down or showing errors

Your monitoring app — Enphase Enlighten, SolarEdge mySolarEdge, or another platform — runs on the equipment manufacturer's servers, not ADT Solar's. Log in directly at the manufacturer's website. If you've lost your credentials, use the account recovery tool or call the manufacturer's support line with your system serial number. A licensed local installer can also reconnect a gateway that has lost its network link. See our solar repair and maintenance guide for step-by-step troubleshooting.

A panel or microinverter has failed

First, pull up your monitoring app — panel-level monitoring will show exactly which unit is underperforming. For an Enphase microinverter failure, open a warranty claim directly with Enphase. They will ship a replacement unit; you then need a currently licensed California C-46 or C-10 contractor to perform the physical swap, since ADT Solar's license is no longer valid. Expect to pay for that labor out of pocket unless your workmanship warranty covers it. For inverter replacement cost ranges in California, see our solar inverter replacement cost guide.

A roof leak at a panel mount

Roof penetrations made during installation are the installer's responsibility under the workmanship warranty. Since ADT Solar is no longer operating, you have two paths: (1) attempt to reach ADT's existing-customer support line and document the claim in writing, or (2) hire a licensed roofing contractor independently while you pursue the claim. Do not let a leak go unaddressed — water damage compounds quickly. Helios works with vetted, licensed roofing partners and can coordinate an inspection; roofing work is performed by those licensed partners, not by Helios directly.

For panel removal costs if a full re-roof is needed: solar panel removal and reinstallation typically runs $250–$350 per panel — roughly $5,000–$7,000 for a 20-panel system and $7,500–$10,500 for a 30-panel system, with tile or steep roofs at the higher end of the range.

Panel removal for a reroof

If your roof needs replacement, you'll need to remove and reinstall the panels regardless of who installed them. This is a straightforward job for any licensed California solar contractor. Get the gross price and the cost per watt in writing before signing anything. See solar panel removal and reinstallation for a full breakdown of what to expect.

What to gather right now

Before you need service — and especially before calling anyone — pull together these documents and details:

• Your original installation contract (signed by Sunpro or ADT Solar) — this defines what warranty terms were actually promised
• Equipment serial numbers — usually on a sticker on each panel and on the inverter/gateway; also visible in your monitoring app
• Monitoring login credentials — email address and password for Enphase Enlighten or SolarEdge portal
• Permit records — your city or county building department has the permit on file; this is your proof of installation date
• Financing documents — if you have a solar loan, the lender is a separate party and your obligation to them is unchanged; contact them if you have questions about the system
• Any prior service records — emails, work orders, or photos from any ADT Solar service visits

Keep copies of everything in a cloud folder. If you ever need to escalate a warranty dispute, a paper trail is essential.

How NEM 3.0 affects ADT Solar and Sunpro owners in Southern California

If your ADT Solar or Sunpro system was interconnected before April 14, 2023 on SCE, PG&E, or SDG&E, you are grandfathered under NEM 2.0 for 20 years from your interconnection date — that status does not change because your installer exited the market. If your system was interconnected after that date on one of those investor-owned utilities, you are on NEM 3.0 (the CPUC Net Billing Tariff), which pays export rates well below retail. LADWP customers are on a separate net metering program — LADWP is a municipal utility, not subject to CPUC's NEM 3.0, and currently offers retail-rate net metering at an effective rate of approximately 28¢/kWh (26–31¢ effective). See our NEM 3.0 explainer for a full comparison.

Under NEM 3.0, adding a battery to your existing ADT Solar or Sunpro system can significantly improve economics by storing afternoon solar production and discharging during the 4–9 PM peak window, when SCE rates run approximately 48–58¢/kWh. A single Tesla Powerwall 3 installed runs approximately $14,500–$18,500; an Enphase IQ Battery 10C approximately $13,000–$15,500. See our battery storage guide and solar vs. battery under NEM 3.0 for more detail.

Frequently asked questions about ADT Solar service in California

Did ADT Solar go bankrupt?

No. ADT Solar did not file for bankruptcy. Instead, the company made a strategic decision to close its solar operations entirely. ADT continues to operate in the home security industry but is no longer involved in solar installations or service. This matters because ADT Inc. as a parent company remains solvent, which is why it can still theoretically honor warranty obligations — unlike a company that has dissolved entirely.

Is ADT Solar's California license still valid?

No. ADT Solar LLC held a Solar Contractor license (#1080382) with an expiration date of August 31, 2025, and that license was last verified expired on January 12, 2026. No currently active California CSLB license for ADT Solar LLC appears in the public database. Any contractor claiming to work under that license number today is not authorized to do so.

Will ADT honor my 25-year workmanship warranty?

ADT has said publicly that it will, but real-world results are inconsistent. ADT itself is still in business and has said it will honor existing warranties through service partners. Start by contacting ADT's existing-customer solar support channel and getting any commitment in writing. If you hit a wall, file a complaint with the California Department of Consumer Affairs and the BBB.

My Enphase microinverter is showing an error. Is that warranty still good?

Almost certainly yes. Enphase microinverters back their hardware for 25 years. That warranty runs directly with Enphase Energy — it is completely independent of ADT Solar's status. Contact Enphase directly with your serial number to open a claim. You will need a licensed California contractor to perform any physical replacement work.

Can I add a battery to my existing ADT Solar / Sunpro system?

Yes, in most cases. Adding a battery does not require your original installer. Any currently licensed California C-46 or C-10 contractor can assess your existing system and design a storage addition. If your system uses Enphase microinverters, the Enphase IQ Battery 10C is a natural fit. For a system on SCE under NEM 3.0, a battery addition can meaningfully improve your economics. See our battery storage guide for current installed cost ranges and our solar vs. battery under NEM 3.0 guide.

I need my panels removed for a reroof. Does it matter who does it?

No — any licensed California solar contractor can remove and reinstall panels regardless of who originally installed them. Budget approximately $250–$350 per panel for removal and reinstallation. For a 20-panel system that's roughly $5,000–$7,000; for 30 panels, approximately $7,500–$10,500. Tile or steep roofs land at the top of those ranges. See our full solar panel removal and reinstallation guide.

How do I find a licensed replacement servicer in Southern California?

Check any contractor's CSLB license at cslb.ca.gov before signing anything — confirm the status reads "Active," the classification is C-46 Solar or C-10 Electrical, and the bond is current. Get the gross price and cost per watt in writing. Helios Energy Global holds an active California license and serves the greater Southern California area, including Los Angeles, Orange County, the Inland Empire, and the South Bay. See our locations page for coverage details.
