[RE-wrenches] shatterproof PV

[Ray Walters]

Hi Marco;

Regular modules are designed to take quite an impact. I recall one 
manufacturer that fired 1" ice balls with an air cannon at their 
modules, and then let visitors throw baseballs at them. It seems the 
foul balls would be at a lower velocity than a person could throw, but I 
don't know.
Also the Unisolar 64 module has a glass face, so I just don't know of a 
framed module without glass.
Possibly you could add a sheet of Lexan (polycarbonate, very tough and 
transparent) over the top of the array. I would think the losses would 
be less than 10%.

Home Depot sells a corrugated polycarbonate clear roofing panel that 
could possibly be attached over the top of the module.

I've run over it, stomped it, dropped tools on it, it pops right out, no 
cracking.
