I just think we need another layer of<br>> roofing material; we'll need 16 sheets of some kinda plywood. I am leaning<br>> more and more in that direction.....<br>> <br>> But I really do appreciate all your thoughts! And by the way, right NOW,<br>> sunny day time temps are near 70..... Nights are a chilly 35.....<br>> <br>> Chris Daum<br>> Oasis Montana Inc.<br>> 406-777-4309<br>> 406-777-0830 fax<br>> <br>> -----Original Message-----<br>> From: re-wrenches-bounces@lists.re-wrenches.org<br>> [mailto:re-wrenches-bounces@lists.re-wrenches.org] On Behalf Of Richard L<br>> Ratico<br>> Sent: Wednesday, October 20, 2010 6:59 PM<br>> To: re-wrenches@lists.re-wrenches.org<br>> Subject: Re: [RE-wrenches] The perfect solar ready roof<br>> <br>> Chris,<br>> <br>> You've probably already considered and rejected this... Unisolar PVL modules<br>> on standing seam roofing. Solves the structure & wind problems. Goes fast if<br>> installed on the pans before they go on the roof. Price is pretty good per<br>> watt now.<br>> Can't beat the look. Made in USA. I think the only downside is you may not<br>> have enough area to place 5kW. <br>> <br>> I bet it's getting cold in Montana. You could stick the modules on the pans<br>> in a heated space somewhere. This would really cut down your time and<br>> exposure on the roof.<br>> <br>> Dick Ratico<br>> Solarwind Electric<br>> <br>> <br>> <br>> --- You wrote:<br>> Dear Wrenches<br>> have a composite (shingle) roof at hand, and the owner wants to upgrade it<br>> to a metal roof and install a 5kw+ array on it. The rafters are those<br>> (sort of) particle board I-beams covered with 1/2" plywood (and shingles).<br>> What's the best metal roofing you could suggest--and would you beef up the<br>> wood to lag into?<br>> Thanks for all your input.<br>> Chris Daum<br>> Oasis Montana Inc.<br>> 406-777-4309<br>> 406-777-0830 fax<br>> --- end of quote ---<br>> _______________________________________________<br>> List sponsored by Home Power magazine<br>> <br>> List Address: RE-wrenches@lists.re-wrenches.org<br>> <br>> Options & settings:<br>> http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org<br>> <br>> List-Archive:<br>> http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org<br>> <br>> List rules & etiquette:<br>> www.re-wrenches.org/etiquette.htm<br>> <br>> Check out participant bios:<br>> www.members.re-wrenches.org<br>> <br>> <br>> <br>> _______________________________________________<br>> List sponsored by Home Power magazine<br>> <br>> List Address: RE-wrenches@lists.re-wrenches.org<br>> <br>> Options & settings:<br>> http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org<br>> <br>> List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org<br>> <br>> List rules & etiquette:<br>> www.re-wrenches.org/etiquette.htm<br>> <br>> Check out participant bios:<br>> www.members.re-wrenches.org<br>> <br></div> </body>
