But thats the real problem. We havent hit that magic 25 year cycle on most installed systems. So we really dont know

We do HALT testing now, which is close but not 100% reality. But we do have a ton of failure mode data on what was making those panels break and everyones comfortable enough to do 25 year warranties with degradation guarantees and many of the asset managers put production guarantees in the contracts too.

That's putting your money where your mouth is, this thing will produce or I'll pay you.

I have family in Florida that has an older system. They had to replace the roof prior to covid. They then found out that a significant number of panels needed replacing as they were being reinstalled

Def a problem for older systems. New micro or MLPA will tell you in the app if you have not just a module go down, but a cell or even an underperforming cell. System operations has really moved a lot in the past few years.

And they hadn't even made it to 25 years

They were early adopters honestly. But people have to do that for the tech to advance and it has a lot, especially in the past 5 years. We used to pull production from Itron can meters. Now i have an API to the inverter and i'm hitting that 100 times a day to pull telemetry and run that through tools to ID problems.
