To Mark:

Congrats on the solar installation. I looked at installing one as well, however Maryland only kicks in $3,000 towards the installation. The Federal government adds another $2,000 but that still leaves me $20,000- $25,000 out of pocket. My break even cost would be 25 - 30 years out. Granted - installing solar does add to the value of the house but that value is not realized until the house is sold.
(So while it is good for enviornment it is not good for my pocket book .)

Massachusettes is one of the best states to install solar. They kick in 50% of the qualified cost for a Multifamily or Small Business setup. So on a $30,000 system - it would only cost you $13,000 out of pocket (30,000 less 15,000 from state less 2,000 from federal.) Ones break even point would be within 10 - 15 years a much better ROI (Return on Investment)

Mark - how do the numbers work out on your system?
