Commercial panels are supposed to meet the British "iceball test" (BS 
EN 12975-2:2001) as part of the Australian Standard for Solar and 
heat pump water heaters (AS/NZS 2712:2002). The ANU PV/Trough Array 
was designed with "Impact resistance: sufficient to withstand hail" 

But I haven't seen what has happened to the campus. There are 
some  photos on Flickr at 
<http://www.flickr.com/search/?q=anu+hail&m=tags/>. Apparently my 
office was ankle deep in water, so I have been keeping out of the way 
of the recovery.

The ANU computer system continues to operate and I have suggested one 
of my colleagues go to one of the open building and use his wireless 
laptop from there, via the ANU's wireless Internet service. There are 
WiFi access points around the campus and in the student 
accommodation, for staff and student use.
