Qcells warranty for solar
The short version
Qcells doesn't cover everything, but keeps solar panel and power output covered to 25 years. That full coverage is shorter than most of the 14 brands we compared, which typically cover 1 year in full. You don't need to register to get this coverage.
From Qcells's published warranty, checked October 2026.
