Of course it can. There are many ways to measure efficiency. Watts output at standard test conditions/ energy out vs energy in in one very lab specific set of circumstances is but one possible way. Cost efficiency per watt is a valid measure. Efficiency in total watts generated per a particular roof space (which will include packaging efficiency as well as panel energy conversion efficiency) is another.

Google "cost efficiency" in quotes.

I would respectfully desagree. Efficiency is one thing, cost is another. The most efficient panels are also the highest price per watt.
There is only one standard used in the industry for measuring the efficiency of solar panels, and has nothing to do with what the manufacturers price is.

In the context of the OP's first sentence, he seems to be looking for the most bang-for-the-buck, an efficiency that is measured in output/dollar = cost efficiency. I don't think he is totally concerned with electrical efficiency, based on his post. I was wrong once, though--1976 or so, IIRC. :B
