One Tesla Solar customer said their rooftop system stopped producing in July — what they described as the best month of the year for solar output — and that the earliest available service appointment was Aug. 14, leaving them relying on grid electricity during a peak period for solar savings.
The user said on Reddit that they had been relying on grid electricity for nearly a month and believed a panel might be the problem because the inverter showed a “2xB” code. 
They said, “System stopped producing in frickin JULY – the best month of the year to produce!”
Repair timing — especially during a high-production month — was the main theme of the discussion.

Replies suggested the appointment could result in anything from a same-day repair to a much longer chain of diagnostics, parts orders, and return visits. 
One said, “I would expect either the system to get fixed, or at least diagnosed and hopefully not a long wait for parts to arrive.” 
Another said, “Moral of the story, don’t get your hopes up. They likely won’t have the parts you need and it usually is not an easy / quick fix.”
If a system goes offline during summer, homeowners may lose their best chance to offset heavy air-conditioning use with solar production.
FROM OUR PARTNER
Want to go solar but not sure who to trust? EnergySage has your back with free and transparent quotes from fully vetted providers that can help you save as much as $10k on installation.
To get started, just answer a few questions about your home — no phone number required. Within a day or two, EnergySage will email you the best local options for your needs, and their expert advisers can help you compare quotes and pick a winner.

Users described waiting on parts, getting separate delivery notices, and dealing with repeat visits before the repair was fully finished.
Experiences differed widely. A user who had the needed part available said the inverter was “replaced within an hour or so.” Others reported receiving the wrong inverter, and another user said they were billed estimated payments under a power purchase agreement even while the system was showing zero production.
The OP also suggested that service may move more smoothly when the site is easy to work on, arguing that dirty roofs and heavy bird droppings can complicate repairs and lower a home’s priority.

Taken together, the comments suggest a few practical steps: keep a record of the error code, confirm whether the technician is expected to arrive with the likely replacement part, and make sure the system is fully tested before the appointment ends. 
One user said, “Before they leave retest everything! eStop, go off grid, check the app etc.”
For shoppers, comparing providers and contract terms upfront may help reduce risk.
