1 in 5 solar panels are failing—and it’s not because of hail.
A quiet reliability crisis is cracking open across the industry, and it starts with glass.
In this eye-opening conversation, Nico Johnson sits down with Tristan Erion-Lorico (Kiwa PVEL) and Dr. Teresa Barnes (NREL) to uncover why glass breakage has become the #1 cause of solar module failure. Backed by PVEL’s latest reliability data, they expose how design shortcuts, material stress, and quality-control lapses are pushing failure rates to an alarming 20%.
You’ll learn:
🔹 Why “tempered” glass isn’t always truly tempered
🔹 How glass is allergic to metal, actually
🔹 Why thinner, lighter glass can mean bigger, costlier failures
🔹 What manufacturers, EPCs, and buyers must do now to prevent losses
If you build, buy, or bank on solar panels, this episode could save your next project from shattering—literally.

CrimeLess: Hillbilly Heist
It’s 1996 in rural North Carolina, and an oddball crew makes history when they pull off America’s third largest cash heist. But it’s all downhill from there. Join host Johnny Knoxville as he unspools a wild and woolly tale about a group of regular ‘ol folks who risked it all for a chance at a better life. CrimeLess: Hillbilly Heist answers the question: what would you do with 17.3 million dollars? The answer includes diamond rings, mansions, velvet Elvis paintings, plus a run for the border, murder-for-hire-plots, and FBI busts.
