Have no knowledge in this field but if your solar panel material degrades in light that would seem to be an insurmountable problem to me.

Output degrades at about ~1% a year. EOL for a solar panel is typically about 30 years. It will still generate power but if it is a commercial operation then it will likely be in consideration for replacement. I imagine there would be a large secondary market in the future for used but still functional solar panels as utilities and smaller solar farms replace the panels and possibly funneling into the residential market.

For "tend to", finding a design that avoids it is surmounting it.

Or if you get it slow enough.
