Federal Solar Grant Worth it or not?

do you think Harlem and Bronx NY dudes, that a Federal Solar grant is worth it?  Any of you try putting up solar power or even solar hot water heaters in Harlem or the Bronx?  Just wondering, I know this is more of a rural thing.  Anyway, imagine having to clean the snow off those things.  Do you think it will help you in your bills?  Maybe with a good, fat subsidy.
