[RE-wrenches] shatterproof PV

Hi Guys,

 

The discontinued Unisolar US64 did not have any glass on the face.

 

A great product, a shame they stopped manufacture.

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.

I'm looking to install a 10-20 kW system on a roof that's going to be
getting falling foul balls from a nearby baseball field.

 

The roof is not appropriate for any of the Uni-Solar peel-n-stick products.

 

Any recommendations for anything else out there that does not have a glass
glazing?Hi Marco

 

Thanks,
