ADT Solar Out of Business: Who Honors the Warranty (2026)
ADT shut down ADT Solar (formerly Sunpro) in January 2024 without a bankruptcy and stated it would honor the 25-year workmanship warranty and production guarantee.
There is no published ADT Solar service phone, so claims go to ADT in writing. For urgent repairs, hire a contractor, keep the invoice and seek reimbursement.
ADT Solar was the residential solar business ADT built by buying Sunpro Solar in 2021 for about $825 million and exited in January 2024 after closing 22 of 38 branches; ADT remains solvent and responsible for the warranties it issued.
What happened to ADT Solar
ADT announced on November 9, 2021 that it would buy Sunpro Solar for about $825 million and rebranded it ADT Solar. On November 2, 2023 it said it would close 22 of 38 branches, and in late January 2024 it announced a full exit from residential solar after an $89 million adjusted EBITDA loss in the first nine months of 2023. ADT did not file for bankruptcy and said it would honor its 25-year limited workmanship warranty and 25-year power production guarantee for installed systems.

Did ADT Solar go bankrupt?
No. ADT exited residential solar in January 2024 but remains solvent and said it would honor its 25-year workmanship warranty and production guarantee.
Who services ADT Solar systems now?
ADT retains the warranty obligation but no longer runs solar branches; third-party service companies handle most repairs. Put claims to ADT in writing.
Was ADT Solar the same as Sunpro?
Yes. ADT bought Sunpro Solar (announced November 9, 2021) and rebranded it ADT Solar.
Which states did ADT Solar cover?
Sunpro served 21 southern and midwestern states including Louisiana, Texas, Florida, Alabama and Mississippi; ADT Solar had 38 branches before closing 22 in late 2023.

Yes. Enphase microinverter and gateway warranties are with Enphase, independent of ADT. Register the system in the Enphase App.
Is there an ADT Solar customer service number?
No published solar service line was found as of October 10, 2026. Warranty claims go to the equipment makers (for example Enphase), and labor on an owned system goes to an independent licensed contractor.
