Re: [RE-wrenches] concrete roof tile install

I like the idea of tile hooks, if flashed properly, but they are not suitable for high design wind speed environments in my experience. Unirac's tile hook tables require anything over 140mph to have effective spans of 24 inches when trusses are 24 inch on center (32 inch for 16 inch OC). That's way

Re: [RE-wrenches] concrete roof tile install

We do flat tile roofs all day out here in CA. We've used these flat tile roof hooks by Solar Roof Hooks to great success. Pull up a tile, find a rafter, pilot holes, goop, put in a hook with lags, more goop, and then a piece of roof-

+1 on Quickmount Tile Replacement Mounts We do tons of tile in SW Florida and we're in the midst of doing two communities of new construction totaling over 450 tile roof homes right now - about half flat tile. All are getting Quickmount replacement flashings. There are some snags, but all in all t

Re: [RE-wrenches] concrete roof tile install

We have always loved QuickMount's products for flat tile. Definately not the cheapest solution, but the robust double flashed method gives high confidance of leak-free installation. We deal with high wind/snow loads and they have excellent engineering specs. There are many cheaper products usable a

Re: [RE-wrenches] Rodent/Pigeon/Critter Guards

Hello Benn, We have been addressing this issue here in Colorado for quite some time and have had great success with our methodology(3000+ critter guards=no failures yet). We utilize a specific wire mesh that is a little more rigid than most available online. We take time to prep the material so th

Re: [RE-wrenches] concrete roof tile install

Jay - I'll add one big point to working on tiles - make sure you check the condition of the underlayment before starting work. Tiles can last for a long time, but the underlayment (felt paper) on older tile roofs starts to become brittle and disintegrates. Water during heavy wind storms works its w

Jay There a mounting systems by Quickmount and maybe Sunmodo just for tile, if the tile is good then this may be all you need, that is IF the roofing material is good. Jerry On Jun 22, 2017 4:57 AM, "jay" wrote: > HI All, > > I’ve never worked with flat concrete roof tiles before. And have an >

Re: [RE-wrenches] concrete roof tile install

Hi Jay - We don't do a whole lot of tile, but when we do we've switched to using a tile replacement mount product. Quickmount and EcoFasten both make similar products: http://www.quickmountpv.com/downloads/datasheet/QMPV-datasheet-QMTRM-TileReplacement-web.pdf http://www.ecofastensolar.com/store

[RE-wrenches] concrete roof tile install

HI All, I’ve never worked with flat concrete roof tiles before. And have an install that does have them. Something like a Striata type. Wondering what recommendations folks have for how to mount with them. Its not a large system currently only 6-9 x 280 60 cell modules. Probably doesn’t mak

I have used the old Sanyo bifacials on a Pergola in snow country with very good results. They had frames though and have held up really well. I have some single axis trackers at my place that I would really love to update the modules with the new Panasonic bi's. The frames have always been the thi

[RE-wrenches] Voltage settings on PVP-4800 inverter

Hi All, Is anyone out there familiar with PV Powered inverters? If so, is it possible to adjust the voltage setpoints? The installation manual I downloaded off their website says it is adjustable, but tech support claims that it is something that they intended to do and never got around to. I cann

[RE-wrenches] Bifacial modules on pole mounts

Hi Wrenches, We have started thinking about experimenting with bifacial modules on pole mounts in remote locations where snow is a big issue; the idea being we could still be collecting some energy when the front of the module is covered in snow. I don't have any experience with bifacial modules,

[RE-wrenches] Experience with Heliene PV Modules?

Dear Re-Wrenches - Do any of you have recent experience with the HELIENE 72MHD panel, the large 72-monocrystalline-cell module? I have a client who is considering it for a large project, and I was asked to find out if it is a durable, high-quality product. Feel free to contact me off the List.
