Wow, thanks. So ok, you're saying a cheapo charge controller essentially leaves energy on the table, compared to a more expensive one. Is there any difference in the way it delivers that energy to the battery, that would affect one adversely? I guess what I'm getting at is, is it cheaper to just add a second panel to offset this, rather than pony up for a better charge controller? Yikes this feels like trying to overcome lack of wheeling skill with more horsepower..

How much is a "good" charge controller anyway? Can you put up a link to a one?
