Yeah, just like the 'shovel ready' deals we've already been through.
When this first came up, it sounded like it was thought out in a third year engineering dorm room over more than a few bong hits and Led Zep blasting out of the stereo. Kids who's only real worry is 'When will the pizza be here' , coming up with a fully baked idea for 'free power'.
"Dontcha see man? Free juice for everyone, cause the sun shines, like, every day!"
The mundane details, like how to keep the mirrors clean, or how to deal with clouds or contrails(?), were left to the few grownups in on the plan. Unfortunately, the grownups were too concerned with how to keep the money in their pockets, and not too much how to make the plant work.
Hence, the 'On the fly" aspect of this plant.
And truly, did anyone expect more?
Haste makes waste.
