LPG Posted February 4 Share Posted February 4 Hi Guys I need to mount 4 panels on a Poly-carbonate IBR roof. What type of mounting do you recommend ? I ask such a strange question because there are no "Solar Shops" within 100Ks, so I cant just go to the shop and ask. Much appreciated LPG Quote Link to comment Share on other sites More sharing options...
Virwat Posted February 4 Share Posted February 4 How is the sheeting fastened and to what? Quote Link to comment Share on other sites More sharing options...
TimCam Posted February 4 Share Posted February 4 Normally a hanger bolt is used if into wooden beams. https://www.solar-shop.co.za/schletter/380-hanger-bolt-10x200.html Quote Link to comment Share on other sites More sharing options...

I guess a type of hanger bracket could perhaps be used. Here I think we must ask the installers for their view. @Taleb @Steve87 @Leshen Quote Link to comment Share on other sites More sharing options...

LPG Posted February 6 Author Share Posted February 6 Thanks for the information. The roof is mounted on wooden rafters. One more question. Do I bolt rails to the hanger bolts or are there clamps that attach directly to the bolts ? Cheers Larry Quote Link to comment Share on other sites More sharing options...
Virwat Posted February 6 Share Posted February 6 Rails to hanger bolts. Clamps to rails. Quote Link to comment Share on other sites More sharing options...
Vaal Posted February 7 Share Posted February 7 (edited) What about a couple of m of P2000 rail? It is mostly available from electrical suppliers. You can mount it to the rafters with threaded bar and it will make that the poly sheets can expand under the panels. Nb if you make a hole in the poly sheet, make it a as big as possile as long as long as it doesn't stick out under the washer. A 6.6m long poly sheet"s expansion is enough to break tec screws when it gets cold. To stop the plate from ratting I put a piece of conduit, cut to length under the ridge with just enoug tension so that the sheet can float.
