Yeah on Model 3/Y and 2021+ S/X it's only minimal screen electronics and ser/des glue to encode/decode touch and video in the screen itself. All the expensive bits are liquid cooled. I can't promise that the screens will last forever in hot climates, but they should be way more reliable than in other newer cars where the computer is still part of the screen assembly. If it does fail, it's pretty cheap to pop a used one in there, only takes a few minutes, and no software is involved. Will probably cost less than $500. The best you can do for avoidance is obvious, park inside/in shade, or at least cover/tint, or run cabin overheat protection. I think the screen will last the effective life of the car if those reasonable precautions are taken. (I park my Tesla in a garage)
As for microinverters, I am somewhat against them from a reliability standpoint, the temp cycling is extreme, and it's hard to make them very reliable, though enPhase has done a good job. On my system I use a SMA inverter with series-strings, and the inverter is inside a climate controlled shop. With the newer rapid disconnect requirements, series-string is now less attractive, because you still have to have power electronics on the roof, but luckily my system was before that.
