Aye, that's what I was hoping to get (New York State would have 
given like 50% money back).... but alas I went and bought a house 
with a west/east facing roof, and a gigantic tree due south from 
me.

The installer estimated I could still get maybe 70% of the 
system's capacity out of it, but the tax rebates get small fast 
if you go below 80%. My electric usage is small too, so the cost 
of installation adds up....

but still, it is virtually guaranteed to pay for itself over its 
lifetime and I have a good chance of turning a profit from it. 
That's so cool.

Only downside is the upfront cost, and that isn't even *that* 
bad. And I guess my equipment waiting to be installed uses a grid 
tie inverter, so if main power goes out, I'm still out, no 
independence there. But buying batteries and switches for that 
would just about double the cost, and 99% of the time, grid power 
is on anyway so just not worth it for me.
