WARNING
To prevent personal injury, or damage to panels, unit or structure, be sure to observe the following:

nor cause damage to objects or structures nearby, nor will the panels be subjected to damage (e.g., being bent or scratched).
While handling or stowing the panels, consider any weather conditions, especially windy conditions, that may cause panels to be blown
around and battered.
