That under the solar panels is the hotest place on your roof..
My TC roof is made of plywood coated with epoxy and marine enamel,
Ive noticed that below solar panel which is about 3 inches above roof the paint got completely cooked and was peeling like crazy..
I sanded it all clean and will lay on EPDM rubbed membrane to avoid continuous painting.. Also placed thin aluminum sheet under the solar panel to keep heat away from the roof in the future..
