But thats a 24 hour average so its not going to tell you what the peak 
power is.

 From the little data I have right now I would say yes.

No.  But the site I have the most info from is in Kenya which is 
equatorial sun and the other 2 US fail reports were from the Southern US

What country, city in South Africa has the other panels?  That's where 
the other fail report is from.
