Series 200 UL Ground Mounted System Layout Your System Typically most ground mounted arrays are installed in a landscape configuration, with the long side of the PV modules horizontal and the rails running up the slope. This is different from roof mount installations which typically are in a portrait configuration with the long side of the module running up slope and the rails running horizontally. Notes - Module mid clamps are installed between modules in a row and require 0.
Concrete Pier Series 200 UL Step 2: Excavation & Pipe Installation Required Tools: 12” diameter Excavation Drill Auger Portable Band Saw (18 tpi) Concrete Mixer Basic Concrete Tools String Line Surveying Marker Pen or Paint Materials Needed for Concrete Pier Install: Sched 40 or 80 1-1/2” Pipe w/ 1.
1) Excavate hole 2) Pour concrete Series 200 UL Ground Mounted System Step-by-Step Instructions 3) Place post 4) Measure & cut posts 1) Prepare to excavate holes by measuring and staking hole locations. Set first stake and run a string perpendicular to true South and set second stake. Stake remaining corners of the array according to the plan layout. Excavate core footings at marked location to the depth indicated in your state’s Engineering Letter.
Grade Beam Series 200 UL Required Tools: Backhoe tractor with 12” Bucket Concrete Mixer Basic Concrete Tools String Line Surveying Marker Pen or Paint Materials Needed for Grade Beam Install: Sched 40 or 80 1-1/2” Pipe w/ 1.
12” Wide Grade Beam Footing Option Series 200 UL Ground Mounted System Step-by-Step Instructions 1) Prepare to excavate grade beams by measuring and staking hole locations. Set first stake and run a string perpendicular to true South and set second stake. Stake remaining corners of the array according to the plan layout. Excavate grade beams at marked location to the depth indicated in your state’s Engineering Letter. Grade beam size may vary depending on jobspecific conditions.

1) Slide all brace fittings onto posts 2) Install socket tees Series 200 UL Ground Mounted System Step-by-Step Instructions 1) Determine the necessary cross bracing and required structural fittings before horizontal pipes are installed. Slide all brace fittings onto vertical pipes. If needed, cross bracing will be specified on the plans and in the BOM (needed if verticals are over 5’). 2) Determine the required number of single socket tees and slide onto the horizontal pipe.
Installing and Leveling Rails Series 200 UL Required Tools: Level String Line or Spare Rail Pitch Meter 1/2” Socket Wrench 5/32” Allen Key Torque Wrench Materials Needed to Install Rails: Ground Rail Pipe Clamp Assemblies Step 4: Rail Installation Pipe Clamp to Rail Assembly Materials Included In Wire Clips: (1) SnapNrack Wire Clip Dimensioned Wire Clip 14
1) Determine rail layout Pipe Clamps Torque: 12ft-lbs Series 200 UL Ground Mounted System 2) Place pipe clamps & rails Step-by-Step Instructions 1) Find center of array and mark edges of each module on the lower horizontal pipe. Determine the distance from the lower horizontal to the edge of the rail. Mark all rails at this distance. 2) Place pipe clamps on horizontal rails where markings are placed. Next, place rails where markings are placed.
