Hi Guys,
The discontinued Unisolar US64 did not have any glass on the face. A great product, a shame they stopped manufacture. Carl Emerson Free Power Co. Web www.freepower.co.nz 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%. http://www.modernplastics.com/lexan.html Home Depot sells a corrugated polycarbonate clear roofing panel that could possibly be attached over the top of the module. http://www.homedepot.com/h_d1/N-5yc1v/R-100049922/h_d2/ProductDisplay?langId =-1 <http://www.homedepot.com/h_d1/N-5yc1v/R-100049922/h_d2/ProductDisplay?langI d=-1&storeId=10051&catalogId=10053> &storeId=10051&catalogId=10053 I've run over it, stomped it, dropped tools on it, it pops right out, no cracking.

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, marco provision_highres_solar_logo2 with C-26351 Marco Mangelsdorf, President 69 Railroad Avenue, A-7 Hilo, Hawai'i 96720 (808) 969-3281, 934-7462 facsimile www.provision-solar.com <http://www.provisiontechnologies.com> _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
