The short answer
A leak under solar panels usually comes from a mount penetration that was not properly flashed, or from the roof itself failing beneath the array.
The installer’s workmanship warranty covers their penetrations; the roof covering is the roofer’s or yours. Many repairs need some panels lifted, so the installer and roofer often have to work together.
Leaks under an array
The source decides who pays.
if within the workmanship warranty.
Roof shingle warranties can exclude it.
Who is responsible?
Code requires penetrations to be flashed and sealed. If a leak tracks to a mount, the installer’s workmanship warranty is the first call. If it tracks to the shingles or underlayment away from mounts, it is a roof repair. Note that GAF’s shingle warranty, for example, excludes flashings and metal work.
