Solar isn't a great proposition where I live. Grid power (fueled primarily from coal) is so cheap here that it's hard to make the numbers work out in favor of solar panels on my roof. But there is something psychologically appealing about the idea of driving my car on stored sunshine... knowing that I'm driving on burning coal doesn't feel quite as good. Has anyone out there installed solar panels just for the feel-good aspects?! Am I crazy to be considering it?
