Solar panels on metal roof

carajon
18 years ago

We are thrilled that our solar panels (pv and thermal) will be installed soon. We were expecting to install them with S5 clips onto our metal roof (brand: Everseam). Now one of the solar guys is getting nervous about whether the clips will hold, so is suggesting that we put bolts through the roof to hold the racks that will hold the panels. Now I am worried about putting holes in the metal roof.

I was wondering if anyone else has had any experience with solar panels on metal roofs?

Thanks!

    We're still in the planning stages of a PV system using the same clips. There is no way in heck I'd allow the solar contractor to penetrate the metal roof membrane. This clip system is one of the main benefits of the metal roof/solar panel combination!

    Are these clips for use on a "standing seam" metal roof?

    Yep. Here's their website.

    Hi,
    I have 7200 Watts of GE 200W PV panels and 2 Heliodyne 4 x 8 SDHW panels mounted on a standing seam metal roof with the S5 clips. The only roof penetration is the conduit for the wires. Rock solid.

    I live in South Florida and I'm worried about hurricanes and whether the S5 clips would stand up to the winds or whether they might tear the metal roof off. I had the panels taken off the old shingle roof and now they are just sitting in my back yard. Anyone have any thoughts or opinions?

    Yep. What's your address? ;-)

    (Just kidding, but with what PV costs these days I sure wouldn't leave them in the back yard!)

    That was my thinking, for the Florida house. Now that I am
    importing, I got a price on 240 watt PV panels for $240 each,
    FOB. I need to purchase a minimum of 40. Good deal? FPL is continually increasing prices so I think that the dryer, cooktop (oven needs to be electric), and water heater needs to be gas since it is around .50c/therm. This will take the load off of the fridge, freezer, and pool pump at least 50% if my calculations are correct, based upon a 4.8 kw system.

    the clamps are definately the way to go. Is your roof Standing seam? There are have several jobs that are out there. One with over 10,000 points of attachment and no roof penetrations. PV integrators are actually installing metal roofs just to have the clamps availablility. As far as the holding strength of the part, its is definatley strong. Almost all cases it is stronger than the roof clips.

    Yes, my roof is a stanting seam. Can you tell me where some of the jobs are? I didn't understand when you said "almost all cases it its stronger than the roof clips".

    I can't believe this thread is still going on! When I posted about a year ago our house was still a plan on paper. It's about 3 months from completion now, and our solar contractor just installed the PV panels on our metal roof. In the snow, no less.

    My partner has a little website with construction pics on the first page. At least today, a pic of the new solar panels attached to our standing seam Galvalume roof with S-5! clamps is on the upper right of the first page at the following link (the progress pics change often so it may not be there the next time you look).

    Interestingly "This old house" (for what it's worth) is doing a bungalow with a standing seam metal roof and solar panels. I believe they are using similar clips to connect to the standing seams on the roof to attach the panels

    In the past, I've purchased the S-5 clamps/clips from LMCURBS...excellent lead times and great technical support.
