Editorial Verdict: Which is Better for You?
ADT Solar's warranty stack -- particularly the Enphase standard and 25-year roof guarantee -- is genuinely stronger than Sunrun's. Sunrun wins on financing flexibility (PPA) and sheer scale. If a PPA is on your shortlist, Sunrun is your only option between the two.
Choose ADT Solar if...
Homeowners who value ADT's brand backing, want Enphase microinverters as standard, and need the 25-year roof guarantee that is stronger than most competitors.
Choose Sunrun if...
Homeowners who want a PPA option (ADT does not offer one), need the broadest geographic coverage, or are specifically shopping on lease structure and no-money-down accessibility.

ADT Solar (formerly Sunpro Solar, rebranded after ADT's acquisition) leverages the ADT brand's consumer trust and financial backing to compete in the premium segment of the residential solar market. The company's strongest selling point is its warranty stack: the combination of a 25-year roof guarantee, Enphase's best-in-class product warranty, and a 10-year workmanship guarantee represents one of the more comprehensive coverage packages available from a national installer.
Enphase microinverters are standard on ADT Solar installations, which is a genuine quality advantage — microinverters enable panel-level monitoring, reduce shading losses, and tend to have lower failure rates than string inverters over long time horizons. The trade-off is pricing: ADT Solar sits at the premium end of the national market.
About Sunrun
Sunrun has been the dominant force in residential solar since going public in 2015 and completing its acquisition of Vivint Solar in 2020. The company's core competitive advantage is its financing infrastructure: Sunrun pioneered the modern residential solar lease model and continues to offer among the most flexible no-money-down structures in the industry, including both lease and power-purchase agreement options that shift ownership, maintenance, and performance risk to Sunrun rather than the homeowner.
For homeowners who want to own their system outright, Sunrun competes on breadth of equipment selection and geographic reach rather than price. Where Sunrun truly differentiates is in markets where local installers are thin: the company's logistics network means predictable timelines and post-installation support in states where boutique alternatives are scarce.
