I don't live nearly that far north and the low sun angle for much of the year frequent cloud cover and couple weeks a year that a panel will have snow on it adds up to it just not being economically viable vs other generation methods. If you DIY the whole thing out of used panels and other low cost parts then it makes good sense but that is a huge time sink but that's kind of the exception. I hate my utility and look into stuff like this every year or so so it's not like I'm using 2010 numbers for panel prices either.
