If they cost less than 20% more _total_, including installation costs, which is interesting because it means the higher the installation costs in a particular area the more likely it is to be worth the added cost of the more efficient panels (which presumably aren't more difficult to install than traditional panels).
The numbers given have to be incorrect.
