Jason, Thanks for the preliminary failure analysis of the latest hurricane damage. Do you have any photos which shows the bent mounting plates for the micros? Wouldn't that be an indication of the force applied before something gave up? Good call to get new micros when the leads and their attachmen

Hurricanes wind create both suction up lift and direct pressure against the glass frame wall of the module -- if a module is to be held securely it must be attached 1/3 or 1/4 of the way from top to bottom by each of the two rails . If modules are facing due South and the wind force comes from the
