Friends: I tell any prospective employee that in order to become a solar electrician, one must first be a qualified electrician. I am convinced of this point. Being a solar electrician adds much complexity on top of the traditional trade. However, not all electricians are good electricians.

Re: [RE-wrenches] Mounting on rock

Aaron: I recommend you consider a ballasted system. We have installed them on the ground to good effect. We grade a gravel surface to provide a level pad. With soil underneath we bound the area with railroad ties or similar, pegged into the soil to keep the gravel together. On your rock

Re: [RE-wrenches] Mounting on rock

We've welded a flanged plate to the bottom of the pole and then set epoxy anchor bolts into the rock.  Another option we've tried is drill a 8" hole into the rock to get the base of the pole a foot down into the rock and then poured a reinforced block of concrete on top of the rock.  smaller

Re: [RE-wrenches] Mounting on rock

Thanks everyone. Sounds like most have had the opportunity to do this. I can't believe that in the Colorado mountains this is the first time I am running into this situation in 12 years of business. I'm excited to see how it works. A concrete pad for the anchor plate will work out perfectly.

Re: [RE-wrenches] Mounting on rock

Hi Aaron-- In high strength concrete, we've used red head trubolt wedge anchors, with 1/2" plate (6x6), four anchors/plate, with the posts welded to the plate. This setup passed engineering muster. The anchors were 3/4" by 4-3/4". The racking posts were a tripod of 4x6 stock welded to a pipe

Re: [RE-wrenches] Mounting on rock

On a roof ground mount you just need four holes the front one should be relatively level if you have to shim them with concrete or something or even steel plates that would work The rears are adjustable legs so it’s no issue Look at DPW roof ground mount you’ll see what I mean Bob > On Apr

Re: [RE-wrenches] Mounting on rock

I'm pretty sure Unirac has a flange base that is designed to attached to the bottom of a threaded pipe as part of their ULA rack that can be used to mount directly to rock. On Thu, Apr 12, 2018 at 9:53 AM, Aaron Mandelkorn wrote: > Thanks all. The flange plate was what I

Re: [RE-wrenches] Mounting on rock

Hi Aaron, Granite is a great substrate to mount to (once it's done). You could weld a large flange plate onto the bottom of your pole, and bolt it to the granite using anchor bolts. Rock climbers (including myself) drill into granite all of the time. Bosch, among others, has a great drill and

Re: [RE-wrenches] Mounting on rock

Aaron There are a few ballast roof mount companies that promote their racking for ballast ground mount options. You may want to explore some of those. Peter Giroux ASAE - Original Message - From: Aaron Mandelkorn To: RE-wrenches Sent: Thursday, April 12, 2018 9:27 AM

Hey Aaron, We¹ve done a project similar to this just a little smaller for an off grid client here in AZ. I could share info with you about how we did it off list if you¹d like. Might be a little long winded for the group. Thanks! Chad Waits President/Owner ­ Net Zero Solar 101 W. 5th St.,

If you could get a well driller with a sense of humor you could put a hole in that you could mount a pole the other option is use a DPW ground mount and drill and anchor it in the four spots where is the feet sit Bob ellison But you will have to run ground wire to someplace to get a good

Hi all, I have a customer that requires a mounting option I have yet to encounter. His site sits on top of of a massive hill of granite. It is relatively flat. Are there any mounting options that could work here? We are only talking about (12) to (16) modules for an off grid array. Is there
