[RE-wrenches] shatterproof PV (Durable Uni-Solar)

[Larry Crutcher, Starlight Solar Power Systems]

They were very durable. A few years ago an RV customer had a US64 propped up on the back bumper. They forgot about it and backed up the motorhome to reposition, driving all 30,000 pounds over the module. Flattened and covered with deep rock dents and a puncture, it still works well.
