For Germany the yearly average is 110 W/m² or so. Clear summer days go to >1000, but nights and bad weather days push the average down. Maybe they meant that in the article, maybe they missed a zero.
If they meant it, it seems like an odd comparison without data if the cell scales with power. If it doesn't, it can't properly utilize bright days and would miss out on most of that average power.
