I think your first tranche is more accurate, but with different numbers. I doubt the panels will cost that much (to the developer). At least, if they do.. they won't be competitive.
Here's a company in China doing PV for $100/m2 ($0.50/W), althogh subsidized:
So if Emirates gets 10% of their target (of 10%), that's 1% of 800 million, or 8 million m2 (annually). At 50% of their target, it's 40 million m2.
At $1-2 per m2, SwissINSO would stand to see annual revenues of $8-16 million, or $40-80 million.
It's just a holding company with very low cash requirements, so even on the low end of these estimates, it can be a profitable business very quickly. Today's market cap is $25MM.
Speculative investment, perhaps, but I like the odds at 17c/share today.
