James: Thanks for getting back to me. I think the Navy did a study on the longevity of zip ties. I will look for it and share it.
4-5 or 8 years is beyond most installation warranty periods, so we contractors are not liable. Good news! 4-5 or 8 years is far short, however, of any module warranty period. This leaves the awkward question: What does one do with a perfectly good PV array with the wiring falling down? And another question: Do unsecured high voltage PV leads pose a danger? These are rhetorical questions. Please don't feel they require an answer. Aloha.
