[RE-wrenches] ice accumulation

[Travis Creswell]

What about insulating the back of the array so the solar heat gain would
take the panels above freezing more often and for more hours a day?

Hi Wrenches,

I know this is a nice cool subject for these (hopefully) sun filled  
days. I am working on a telecom system that has some issues with ice  
accumulation on the panels that essentially shut the system down mid  
winter. Wondering if anyone has suggestions to remedy the ice  
buildup. It's an extreme mountaintop environment with very high winds  
at times and the ice cakes up to 2" - 3" on surfaces. There are some  
pics here: www.solareagle/temp/ice.html

Access to the site in winter is totally out of the question so we are  
hoping to find some ideas that might prevent or reduce the ice  
accumulation. When the ice shuts the panels down the communications  
go down.

Someone suggested a slippery spray like RainX might help to prevent  
accumulation but I think it would quickly be washed off/worn out and  
I don't know the uv issues that might reduce power output.
