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

9

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
