Why is this a bad idea, providing the adhesive foam is compatible with the roofing material, stand off and has the sufficient uplift strength.

Lightning arresting system are use adhesive to attach the system to the roof, walk mats are done the same. Trim on cars used double side tape, we hang art on the wall with command strips.
I was thinking compatibility and drainage........Seems like the foam is going to be a crap trap.....

The installation instructions call for the foam/glue to be painted due to exposure to UV light. I wonder about flammability. There was a time when I was tasked with approving solar racking installation instructions for LA County. This company's effort would not make the cut.

On the face of it, I understand how the product achieved a UL Certificate Of Compliance. The Miami-Dade NOA is another thing altogether.

I saw that and went looking for the details. I didn't find an answer as to what they were certified to other than UL2703 Safety. However there is a Miami-Dade Notice Of Approval so there is the assumption that a hurricane won't rip it off the building. The installation instructions are so scant on details that I would question whether there is a legitimate Listing or Certificate Of Compliance.

The concept of gluing the array to a roof covering just seems wrong for many reasons.
 
The Solar Stack looks like it was installed on a modified bitumen roof with a granulated cap sheet. This or a fully adhered membrane roof should be able to take the uplift. I'd be concerned about an installation on a non-adhered system or a TPO roof that is only fastened at the seams.

Pg. 10 of the instructions says that roof tiles must be cut out to install the pedestals! I can imagine how many leaks that would cause.

The claim is that there are no roof penetrations yet the tile is compromised. The foam will trap water and the underlayment will be put to the test.... forever. Other racking mounts applied on a tile roof that I have seen all have flashing or the tile removed and a legitimate roof covering installed under the array. This method is not something that I would trust. But hey now, that's just my opinion.

As to the placement on a BUR or shingle roof....there are requirements such as a clean surface with no loose granules. Fat chance. I have seen solar on shot roofs. The installer will blow and go with nary a thought of the installation instructions. It's the Wild West out there. Inspectors are expected to stay out of the way.

The contractor was not at the site.

The deadfront for the service panel is on the ground. The service panel door will not close.

The solar company is located in Massachusetts. I called them. I got a call back from the local installer. I unloaded.
 
This is located at a large project for condominiums. I was there to inspect the installation of the valves. It took an hour.

When it was done I asked them to energize...The water pressure is 150 psi.

Turns out to be backwards. The top has to be removed, rotated and reinstalled. I got a call from the contractor when I was leaving town. He wanted me to return to the site.
 
Is that a continuous GEC (grounding electrode conductor) system? Or two GEC using the one GE (grounding electrode)?

Trip hazard

Prefer acorn grounding clamp on that application.

The solid #6 originates in a panel and hits the first ground rod:

From there the continuous solid #6 hits a second ground rod and continues to the water main:
