The 20 ish % efficient number is The Solar Industries rating based on the size and amount of power produced at the Ideal temp for the particular solar panel.
There are "stacks" of Solar panels being developed to convert many wavelengths of light which will lead to a higher efficiency.

I'm playing with a single 325w panel and a 3000w battery. I'm getting as high as 85% of the rating. Not sure where the 20% number your coming up with. Following your written theory, my numbers wouldn't be possible.
