## Abstract

An arrangement for attaching PV panels together and to a roofing clamp includes an electrical insulating provision between the attaching arrangement and the roofing clamp while providing electrical grounded connection between the PV panels, per se.

## Claims

### Claim 1

An arrangement for attaching PV panels to a roof comprising:
a threaded rod;
a top serrated metal ring at one end of said rod, said top metal ring including a top electrically insulating cylinder and being arranged for contact with a top part of a PV panel; and
a bottom serrated metal ring at an opposite end of said rod, said bottom metal ring including a bottom electrically insulating cylinder and being arranged for contact with a bottom part of said PV panel, said opposite end of said rod being arranged for engaging a roofing clamp on a roof seam with no electrical contact between said PV panel and said roof seam, said top and bottom electrically insulating cylinders are arranged within said top and bottom serrated metal rings.

### Claim 2 (depends on 1)

The arrangement of claim 1 wherein said top metal ring is arranged for contact with a top part of a plastic side plate adjacent said PV panel and said bottom metal ring is arranged for contact with a bottom part of said plastic side plate.

### Claim 3 (depends on 1)

The arrangement of claim 1 wherein said top and bottom electrically insulating cylinders each include an opening for receiving said threaded rod for providing electrical insulation between said top and bottom serrated metal rings and said threaded rod.
