Solar Panels, for CIVIL discussion

in AZ, our elect rates are .089 per kw - 1st 400kw. then .104 per kw,
I installed 10kw solar array . paid cash, did install my self, (I'm cheap)
our return is great, in that 9-10 mos a yr, they owe me, and the other mos, they
take from the $ saved/ banked,
the do pay me .057 per kw, and we generate on avg 600- 800kw per mo,
the state/ fed's/ elect co, all gave rebates ( not tax credits!) so we ended up with 95%
of our cost reimbursed!
all in all, its a win-win,
my 2 cents..... buy the best controller/ inverter, as so many cheap ones fail,
