Is the Fenix 8 47mm Sapphire Solar Carbon Grey the same as the Amp Yellow Solar?

Yes — same hardware, GPS, training analytics, and solar capability. The difference is the bezel finish (Carbon Grey DLC vs bare titanium in Amp Yellow) and the band colour. Carbon Grey is more understated; Amp Yellow is more visible.

How long will the solar cells work?

Garmin designs solar cells to outlast the watch battery and normal product lifecycle. Solar efficiency does not degrade meaningfully over 5-7 years under normal use. The watch battery will likely be the limiting factor before solar degradation becomes noticeable.
