Enphase warranty for solar

60/100 Warranty ScoreRanked 4 of 14 brands
The short version

Enphase covers solar in full for 25 years, with no partial coverage after that. That full coverage is longer than most of the 14 brands we compared, which typically cover 1 year in full. Some of this coverage only applies if you register the product.

From Enphase's published warranty, checked October 2026.
