Rooftop designs powered by experience

The Integrity Line™ is a purpose-built Solar PV racking system designed to provide installers with strong, cost-effective solutions that keep roofs healthy and Homeowners happy.

Integrity Rail® defies expectation

Sunstack rejects the concept of Minimum Viable Product being a virtue. It's a practice that encourages diminishing quality and we believe the solar industry deserves better.

  • SS01-RCLMP-00
    The Universal Module Clamp secures all modules 30-40mm.
    Use this single clamp as both an end-clamp and as a mid-clamp. Once secured in the rail, the universal clamp stays in place and is ready for modules.

  • SS01-RGRND-00
    The Ground Lug is Insulated so that the bonding occurs within the rail, rather than on top of the rail.
    Easily clicks into the rail.

  • SS01-RMPLE-00
    The MLPE Bracket provides module level power electronics a secure mount to the Integrity Rail. Even larger format 3-Phase or 2:1 Microinverters are held secure and without and sagging.
    Easily clicks into the rail.

  • SS01-SPLC-00
    The Integrity Rail® Splice allows for the structural splicing as well as the thermal splicing of two pieces of Integrity Rail®.  

  • SS01-RENDCP-00
    The aesthetic end cap gives the Integrity Rail® a clean, finished look. The caps offer a deep set so that even the most rough-cut rail looks great on install day and years later.

A Legend Reborn

The SSB1® is what should have come next...

It's very straightforward. Start with the Industry's best performing butyl formulation. Then build a strong, easy to use base that can be used as an agnostic starting point for new builds, detach/reset projects, add-ons, low slope and countless other boutique situations that solar builders find themselves in.
The raised channel offers both added strength as well as the ability to add mounting components like L Feet even after the base is fully attached to the roof.
The debris and water diverter provide egress for water and organic materials that might collect on top of a flat surface and potentially degrade the roofing system.

Pre-assembled options

There are many ways to use the SSB1®. We have pre-assembled a few variations so that installers have an easy time on the roof, right out of the box.

SS01-SPLFRB-00

Optimized to connect the Integrity Rail® to an SSB1®

SS01-SPLF-00

Pre-assembled to simplify using SSB1® with 3rd party rails.

SS01-LFRB-00

Use this SKU to attach Integrity Rail® to S-5! mounts

SS01-SP1-00

This Slide plate assembly allows users to attach most L foot products to an SSB1®

Engineering Excellence

The SSM® offers what no other mount can-

The simple, dual-plate design of the Sunstack Mount®, or SSM®, is an industry first. It combines the ease and cost effectiveness of other L Foot integrated mounts with the simple adjustability that is needed to keep roofs leak free.
The waterproofing of top-quality butyl rubber is integrated to a separate plate from the mount. This makes the mount adjustable at the time of install as well as adding a protective level of engineered tolerance.
