Forming or dismissing a solar weapon is a move action that takes the same amount of effort as drawing or sheathing a weapon (and can be combined with a move as a single move action or used with the Quick Draw feat). Your solar weapon is automatically dismissed if it ever leaves your hand.
I think the auto dismiss would prevent the throwing fusion, but I also wouldn't have an issue with a GM ruling it can be used. I don't think it would be game breaking to allow it.
