Introduction

The Universal Ground/Roof Mount is a simple and universal mounting solution up to 3 solar panels. With its user-adjustable angle settings, the Ground/Roof Mount can support installations in a wide range of locations, as a standalone or multiple mounts intertied in rows. Quantities of panels supported vary by panel widths.

Components List The following parts are included with the GR mounts

Pre Assembly

Step 1: Connect Panel Support Channels

• A. Slide the 10” connector halfway into the end of the one of the panel support and install the 5/16” hardware, Torque to 132 in-lbs. repeat with the second panel support to achieve the overall panel support length
• B. UNI-GR/90 uses two 45” panel support channels. UNI-GR/130 uses two 65” panel support channels

Step 2: Determine foot spacing
There are many combinations of bolting locations and brace overlap configurations to achieve foot spacing’s for the angle(s) desired for your location, the following is a process to make that determination to fit your requirements, or use the general specification chart on page 5.

• A. For the front to rear distance, loosely assemble the A frame section as shown below, adjust the rear leg brace maintaining the minimum 6” overlap or more (“C”) to support the panels at the desired angle to the sun and keeping the rear leg within 60° to 90° to the panel supports. With the “A” frame laying on a flat surface measure the center to center distance between the U-feet to determine the front to rear spacing for the footing.
• B. Keep the rear brace assembled at the overlap determined in prior operation, preassemble the second pair and set aside.
• C. For the side-to-side footing of both “A” frames, the center to center spacing is equal to the center-to-center distance of the mounting holes on the PV module you are using, See mount spacing diagram on PAGE 5.
• D. If you are installing multiple UNI-GR mounts side-by-side, leave a 1” space between the edges of the modules on each mount. To determine the spacing between mounting feet, measure the distance from the short edge of the modules to the mounting hole you are using. The recommended spacing between mounting feet on adjacent mounts is two times the distance from the edge of the panel to center of the mounting hole plus 1”. See the diagram in Step 1 of Final Assembly on page 8

General specification chart
The tables below are suggested front to back foot spacing “E” with the tilt angles that can set at that spacing. “A” is module tilt angle from the horizontal, “C” is the overlap of the back leg sections and “D” is the distance from the top of the module mounting rail to the hole used to connect the back leg. See the diagrams on Page 4.

Step 3: Foot attaching options

• Use Galvanized or Stainless-Steel Hardware
• See Suggestions below:

Step 4 Attaching PV modules to panel supports

• A. Lay the PV Modules face-down on a protected flat surface mounting hole side up.

• B. Lay the flat side of the panel support channels across the panels keeping panels and supports parallel.

• C. Align mounting holes on the panels with the slots on the panel supports, allow
  Approximately 1/4″ to 1” in between PV modules and leave any available left- over support length at the bottom of the array for ground clearance to allow for vegetation management.

• D. Secure with 5/16” hardware and torque to 132 in-lbs. if the mounting holes on the solar panels are large enough. If the panels have 1/4” or 6 mm holes, use the ¼” hardware in the 29-5000-0GR mounting hardware kits and torque them to 75 in-lbs.

Final Assembly

Step: 1 Attach U-foot to footings

• A. Attach the U-foot and backing plate to your footings, align the feet east\west and north\south and torque 3/8-16 galvanized hardware to 16 ft-Lbs. (Concrete footings shown)

Step 2: Attach Preassembled rear braces to footings.

• A. Loosely attach the pre-assembled rear brace to the rear footings (pre-assembled from the prior angle determination step). The “outer leg” is attached to the foot. Lay back away from the front for next step.

Step 3: Attach Pre-Assembled Panel array to footings.

• A. Loosely attach one end of the Panel assembly to the U-feet on the footings.

Step 4:  Attach rear braces to panel supports

• A. Tilt up the array, and the rear braces, and bolt the rear leg into the hole chosen at the distance on step 2 of the “Determine foot spacing” operation, or the general spec chart.
• B. Torque all locations to 132 in-lbs.

OPTIONAL UNI-GR Intertie Installation 51-0520-005
If you are installing 2 or more UNI-GR mounts, you can tie them together to increase stability by putting one of the UNI-GR intertie kits between each mount. This brace is adjustable from 18.25” to 32” and can be used with solar panels that have mounting holes that at between 7” and 15” from the end of the modules.

• A. Loosely connect the inner and outer intertie channels with the 5/16” bolt, lock washer, flat washer, and hex nut.
• B. Place the intertie as shown about midway between the rear brace connection and the end of the panel support channels, slide the channels out to meet the panel support channels, connect with the 5/16” hardware, torque to 132 In Lbs 6 places.
