When I bought the Green Loft building, my loan was able to include money for solar panels. This raised my mortgage payment $90 a month. My energy bill is $200 less a month, but I'm also saving $240 a month in gas because I leased an electric vehicle that I charge with the solar. The car costs me $300 to lease, so it's worked out that I'm being paid a net of $40 a month to drive my new car! The tax credits and increase in my property's value is the gravy!
