End User Module Performance Concerns

just for opinion's sake,

it seems that europe has a tighter window for rated output figures that are nearer to 5% rather than the accepted 10% here in the US.

As far as discoloration, just about everything discolors after 20 years in the sun, but amorphous modules (like unisolar) seem to have the most color changing over the lifetime.

If you where to ask me, I would say "to much money is being spent on R&D." How many times must the wheel be re-invented anyway?
How many billions of dollars have been poured into PV R&D over the past 10 years?
What do have that wasn't there than 10 years ago? (I still see the same thing unless of course we include todays HIGHER PRICES!)
When will the PV module every reach its apogee?
Will there every be a day when there is no longer a need to pour billions of dollars into PV R&D?
When will those billions be poured into putting PV on "roof tops?"
After all, PV is not going to produce usable electricity sitting on a countertop in some laboratory, its only going to produce usable electricity sitting outside in the SUN!
With all these questions there is one I have yet to ask that really stabs at the heart of the matter. Why was the off switch and stop button every invented if no one cares to use them? Speaking philosophically, mankind has turned electricity on, but now it cant be turned off.
