By default in Joomla is used the banner name like a alt text and is no way how to set up more suitable alt text. Moreover there is no title text at all.
Fix this is quite easy:
At first edit help.php file stored at "Joomla_dir"/modules/mod_banners.
Next find line contains:
$image = '<img src="'.$baseurl.'images/banners/'.$item->imageurl.'"
alt="'.JText::_('Banner').'" />';
and replace it by this piece of code:
$image = '<img src="'.$baseurl.'images/banners/'.$item->imageurl.'"
alt="'.$item->description.'" title="'.$item->tags.'" />';
After this you can finally add own alt text within the banner description box and title using meta tags box.
