ADT Solar (Sunpro Legacy) vs. Sunrun (2026): Why Corporate Brand Names Don't Guarantee Solar ROI
Analyzing ADT Solar's exit from residential solar alongside Sunrun's corporate PPA model—and how to protect your roof and wallet.
The Verdict: Independent Local C-10 / Master Electrician + Direct UL9540 Hardware
Homeowners paid ADT Solar $42,000+ trusting a 150-year-old home security brand, only for ADT to shutter its solar division after losing hundreds of millions of dollars. Sunrun remains active, but locks homeowners into 25-year escalating PPAs. Protect yourself by owning open-architecture hardware at fair cash prices.

🔍 FORENSIC ANALYSISForensic Pricing & Contract Breakdown: ADT Solar (Former Sunpro Solar) vs. SunrunHow sales commissions, dealer fees, and lease escalators impact your 25-year ROI
The solar panel and inverter do not know what logo was on the salesperson's polo shirt. An Enphase IQ8 microinverter or EG4 18kPV hybrid inverter produces the exact same kilowatt-hours whether installed by a local master electrician for $26,000 or a national conglomerate for $46,000.

Contact Enphase directly (since 95%+ of ADT/Sunpro systems used Enphase microinverters) to transfer monitoring control and dispatch an Enphase Gold/Platinum local service electrician.
