A Southern California homeowner turned to Reddit after noticing water stains on a ceiling near Tesla solar panels installed three to four years earlier and still under warranty. 

The responses highlighted a frustrating reality for solar customers: when something goes awry, there is a lot of uncertainty.

Here's what to know

After finding "water stains in ceiling" near the array, the homeowner asked on Reddit whether an outside inspection should happen before opening a Tesla ticket.

Fees mentioned in the thread varied when Tesla decided the problem was unrelated to its installation. One person dealing with a cracked tile at a mounting point said, "They have you sign saying it will be $350 if it's not their fault." Another commenter shared Tesla had quoted them a $600 fee in their case.

One user who mentioned they had dealt with a similar issue described a different number. Tesla told them the inspection would cost $300 only if the company was not responsible, while "there's no fee for the inspection and the repair would be done free of charge" if it was. That commenter said the repair was eventually completed, but the process was confusing, and communication was limited.

More background

Finding the true source of a leak can be tricky, especially around a solar array. After checking the attic, the homeowner declared, "Tile roof and no evidence of water," and one commenter cautioned that visible stains can be misleading.

They also said tile roofing changes what inspectors should look for. They advised checking for "cracked or blown out of place tiles on your roof," since tile is meant to shed water but the underlayment and battens below it can still allow moisture in.

They also advised caution with any third-party inspection. As one commenter put it, "If you chose to have a 3rd party inspector before the Tesla inspector make sure they don't change anything having to do with the install." Their concern was that altering the area too soon could make it harder to determine liability.

The thread also suggested that even routine service can drag out. One commenter noted appointments in their area were running about three weeks out and that a follow-up took longer because Tesla needed to source the roof tile. Another suggested that if Tesla doesn't accept responsibility, the next step is likely hiring a roofer.

What can be done?

Before anyone touches the roof or the solar hardware, users gave the original poster urgent advice.

One wrote: "GET A 2ND OPINION! And get them out there before Tesla. Take TONS of pictures."

This could help ensure the original poster doesn't get overcharged or assume liability for something that wasn't their fault.
