I've been wondering "when" myself... I got some IPO shares at $21 and expected a distribution based on the S1A just as you posted above. In a sense I may have lucked out by not getting as many shares allocated to me than I requested so I took the drop in price to add more about the end of July. I'm seriously thinking about doubling up again on Tuesday.
Maybe it hasn't been 45 days, maybe there is no CAFD (Cash Available For Distribution).
Long term I still believe we will get more CASH from this regulated and mandated (the solar mandate) company. Of course FSLR and SPWR will get the bulk of the cash but we will al get the same proportional payout.
