Solyndra's failure had nothing to do with technology at all. They failed because Chinese manufacturers undercut them in price, quite severely. Allegations of dumping (or fraud, on the other side) notwithstanding, what this says is that solar is actually much cheaper and more readily available than Solyndra's investors expected. And that's sort of the opposite of your point, no?

Similarly the Tesla plant is doing exactly what it said it was going to do, when it was supposed to be finished, within the budget it had, and AFAIK is making money. You're asserting that it can't scale because it... worked?!

As far as the Pakistani misdesign, yeah, I'm sure that's going to happen too. Nothing works perfectly.

Nonetheless this seems like a pretty oddly constructed list of reasons why solar is "much worse in production". It seems to my eyes like it's doing much better than expected.
