We had bought these several years ago for sailboat projects. We just
used the remaining ones on our oyster farm. They have worked very well.
I have also used their roll up module for many years on my sailboat.

They were very durable. A few years ago an RV customer had a US64
propped up on the back bumper. They forgot about it and backed up the
motorhome to reposition, driving all 30,000 pounds over the module.
Flattened and covered with deep rock dents and a puncture, it still
works well.

My mistake, I just found a spec sheet on the Unisolar 64, and it
specifically advertises "No glass" and "unbreakable". I worked on
systems with them before, but never sold them, so I assumed the
textured top surface was tempered glass all these years.
Many pardons,

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,
