I call BS on that. This was the performance of ancient modules (early 1980s) after 25 years of operation: https://energiforskmedia.blob.core.windows.net/media/19320/performance-of-old-pv-modules-measurement-of-25-years-old-crystalline-silicone-modules-elforskrapport-2006-71.pdf https://energiforskmedia.blob.core.windows.net/media/19320/p... And this was for modules manufactured in a period with 5-10 year warranties for the product. Today you get 25 year warranties. So you're basically claiming that QA massively worsened in the meantime.
