I think most people look at "value" (Return Of Investment.) These super efficient technologies will need to come down in cost to the point they are a much better value.
Most of the installers around here will not even install trackers anymore because the cost of additional panels is cheaper than the moving tracker, which will eventually need maintenance too.
It's fun to see progress, now how long before it's competitive.*
*(Yeah, I know... almost nothing in solar PV is truly "competitive" thanks to government subsidy intervention, lining the pockets of friends and supporters in the name of "supporting green.")
