RV owner finds X-shaped marks on solar panels after output drops to 533W of 800W
Original source: The Cool Down

An RV owner reported that their 800-watt solar system only produced 533 watts under clear skies, with X-shaped marks visible beneath the panel surface. The marks could not be wiped away, and the panels were less than a year old with no visible damage. Commenters suggested microcracks, also known as snail trails, and advised professional inspection.
