The biggest solar gainer of the day was Akeena Solar (AKNS), but it operates in a different market than the major solar players, focusing on the U.S. residential rooftop area and announcing a deal with Lowe's (LOW) on Thursday.
The rest of the solar pack was in negative territory. Whether that's an indication that the big run-up is winding down, and that wind has moved to another alternative energy area, is still impossible to say.
There may be plenty of room for both wind and solar in the long run, but in the short-term, or at least for a day, solar was the one that seemed a little winded.
