>I hope something was learnt here (other than learning not to do it again) I'm afraid not - the trials played out exactly as the naysayers predicted. Most of the panels cracked under load and failed due to water ingress; those that didn't became woefully inefficient due to soiling. They were dangerously slippery even in ideal conditions, they cost much more than a conventional rooftop installation and they never generated as much electricity as a rooftop installation even when they were brand new. The whole exercise was a complete waste of time and money.
