Types of Residential Solar Mounting Systems
5
Standard Rail-Based Systems
Light Rail Solutions
Railless Systems
Overview of Residential Mounting Systems
Standard Rail-Based Systems
▪ Long history within the industry▪ Intuitive and easy to install▪ Works with majority of roof types and modules▪ Provides integrated bonding per row
Overview of Residential Mounting Systems
Railless Systems
▪ Somewhat New Technology ▪ Simple to install attachments ▪ Typically works with a specific set of modules▪ Provides integrated bonding per array
Rail-based vs. Railless Solutions
Rail-basedModules are laid down onto horizontal rails and clamped on each side

RaillessModules sleeve into bottom row of mounts and are clamped on top side
Features of a Rail-based Solution
▪Easy to learn and teach▪ Installs in stages▪Snap-in components▪One bolt size

Features of a Rail-based Solution
10
▪ Variety of attachments for roof types▪ Accommodates portrait and landscape orientations▪ Array leveling is performed at L foot
Roof Attachments – Composition Shingle
11
▪ Fully flashed roof fastener
▪ Cutting of shingles not required
▪ The L Foot is engineered for maximum adjustability resulting in a flush, level installation.
▪ Industry-best water resistance with no rubber components that get damaged over time.
Metal Roof Attachments
12
▪ The Metal Roof Base (MRB)▪ Robust self-sealing mounting base for metal roofs with flat surfaces
▪ Multiple Seam Clamp Attachments▪ Allows for attachment directly to a standing seam metal roof without penetration
▪ Corrugated Straddle Block▪ L foot is able to mount directly to a structural member without collapsing or crushing
the ridge in the metal roof material
Tile Roof Attachments
13
▪ Designed specifically for flat, S and wave shaped tile roofs
▪ Strong, low-profile roof attachment
▪ Eliminates need for cone flashing and cutting or drilling of tile.
▪ Universal Tile Hook has Quick “drop-in” design:▪ Simply rock arm into base and secure
with single bolt
Tile Replacement Solutions
14
▪Designed specifically for flat, S and W shaped tile roofs▪ Eliminates grinding/cutting of tiles▪ Labor Saving Benefits over standoff solutions▪Net positive tile consumption
▪ Tiles that are removed can be used to replace those broke over the course of install
Features of a Rail-based Solution
▪ Sturdy attachment point for accessories▪Mounting for MLPE and RSD units▪ Allows for array wiring before modules are installed
15
Array Wire Management
▪ Rail profile allows for wires to be run in channel
▪ Eliminates need for cable ties
▪ Protects wires from abrasive surfaces.16
Aesthetics of a Railed Solution
17
▪ L feet hidden under the array▪Clamps and rails match module frame color
Aesthetics of a Railed Solution
▪Rails cut flush to module frame▪Rails are rendered invisible underneath the
array▪Optional skirt provides a nice finished look
18
Choosing the Right Rail for the Job
19
▪Heavier Rail profiles for larger wind and snow loads or when limited to longer spans▪ Lighter rail is a more economical solution when
attachment spacing is due to roof load capacity.
Series 100 Solution
20
▪ Easy to install channel nut of the S100 attachment.
▪ Very easy to teach and learn especially with prior rail experience
▪ 2 full channels for mounting accessories and running wires
▪Channel nut design allows for flexible mounting options and orientations
Market Drivers Impacting Mounting Systems
▪ Increasing pressure to drive down costs of components
