Will most likely get one, but will probably wait a year or two after they come out. Had 46 solar panels installed on the roof last year - approximate 10 years to get the ROI - but of course if electricity rates go up, then it's shorter. Also not taking into account any value added to the house, which can be a positive or negative. Some may just not like the look of solar panels and be turned away, others may see that they are saving $3k a year in electricity and view it as a huge plus. The ROI was only 7 years before the SREC market collapsed in Maryland (sucks - don't see it recovering until at minimum 2019, if ever).
As far as batteries go - the technology is evolving so rapidly that it's best to wait. There is no ROI on them, especially since they have a limited shelf life (unlike the solar panels, which only lose about 10-20% efficiency in 30 years). So the only advantage to having them is if you want to pay a few thousand dollars to have some power when the power goes out. Unlike solar panels where the technology really isn't improving at a rapid rate, battery technology is growing by leaps and bounds seemingly every year in terms of both capacity and lower cost.
I can see in 5+ years down the road, maybe sooner, that it would actually be cost-effective to use the batteries to hold excess power during the day, and power your home at night, as well as provide emergency protection - and possibly be able to be off-grid with solar. But again, we are definitely some years away from that.
In regards to solar shingles - great idea, but again quite a ways away from being feasible. And they are much, much more expensive than panels currently - I think I saw where they are about twice as much. Not to mention possible service costs since they are basically your roof as well (solar panels are relatively simple, very rarely need repairs, and in the event they do - it's pretty easy).
