It’s too bad solar degrades over time. I think it’d be more of a no-brainer if we could actually manufacture it at scale domestically without it losing its efficiency over a 15 year period.

Google says they degrade to 80-90% capacity over 25-30 years, which is ~double your 15 year time period. I've also previously seen people claiming that they then stabilise around the 80% level, and that we don't really know how long their total possible lifespan is because many extant solar panels are outliving their 25 year rated lifespans.
Capacity reduced to 80% won't work for some high-performance use cases, but is pretty decent for most.
>without it losing its efficiency over a 15 year period.
Why is this such a dealbreaker like you make it out to be? It's easily fixed by over-provisioning to account for future losses. Not to mention that power grids almost always have more capacity than what's needed, to account for future growth and maintenance downtime.
After 15 years you can just replace them
