For utility-scale solar farms, these CdTe panels outperform silicon panels over the long haul. This feat should increase the return on investment (ROI) for PV installations and decrease the number of solar panels in the waste or recycling streams. But don't expect the industry to switch to CdTe for all of its new installations, primarily due to the scarcity of materials.

Are there going to be solar farms that have their panels retired early because the amount of efficiency gains from the new tech is so great that it makes bringing end-of-life earlier worthwhile? Or are we still looking more at incremental changes?

I suspect the latter. When you factor in the cost of replacing existing equipment, I'm not sure it makes sense to retire the old stuff before it reaches the end of its originally anticipated life.
