When using a side-mounted rail, orient the Protea L-Foot vertically so the hinge bolt will lock into the square hole on the slotted L-Foot. Tighten the hinge bolt. The rail will now be attached to the remaining slot to fine-tune the rail height. When utilizing ProteaBracket to mount the PVKIT or top-mounted rail, orient the L-Foot horizontally. Tighten the hinge bolt.
Advantages: One part does it all. Fully assembled, the ProteaBracket attaches PV with or without rails to exposed-fastened trapezoidal sheet profiles, including pre-assembled foam core panels/insulated metal panels. Adjustable base accommodates varying rib widths, heights and angles. Attach to the sheeting-only with no messy sealants. Comes with a factory-applied, EPDM pad to ensure quick installation and a weather-proof fit. Rigorously tested for load-to-failure results in sheeting-only; pairs with the PVKIT for a direct-attach solution – or ideal for both side-bolted and bottom-bolted rail mounting. As with all S-5! products, ProteaBracket is warranted for the life of the roof (and PV); Resi or C/I.

How does it install: The S-5-PVKIT 2.0 simply threads into any S-5! clamp or bracket. Eliminates rail altogether. Disk with bonding teeth provides grounding path module to module. The grab seats to the PV module frame by using one simple tool for both clamp and grab, providing a continuous ground path without the need for extra components along each module column.
PVKIT’s pre-assembled components provide a simple, secure and economical method to “lay & play” modules. The PV module itself is the dimensional gauge for placement of ensuing attachments. Finally, the grab is tightened down to the module frame. No additional tools or steps are required. The “free” rails inherent to the roof (ribs and seams) obviate the need for added rail hardware.
Advantages: S-5-PVKIT 2.0 is a rail-less attachment solution for any metal roof type with tested, engineered, direct attachment of modules to standing seam or exposed-fastened metal roofs. With high-tensile, certified aluminum and stainless, the PVKIT eliminates the need for traditional rail methods and offers impressive savings across transport and handling metrics for PV mounting systems. You’re using the rails inherent to the metal roof. Benefits over rails: 85% less weight/collateral load; 70% fewer components; up to 40% hard goods savings; up to 40% labor savings; 25% better load distribution.

How does it install: Installation of SnapNrack Ultra Rail is intuitive and easy to learn. After the array is marked in accordance with the design plans, Umbrella L Feet lag into rafters with patented flashing technology that protects against roof leaks. Rails snap into mounts with spring loaded features to allow the rail to easily slide and be adjusted to the desired location and height. Finally, panels are placed on the rails secured using SnapNrack’s proprietary mid and end clamps as wires are nestled securely into the rail channel.
Advantages: The Ultra Rail profile creates a channel for wires, unobstructed by splices or mounts. It doesn’t rely on zip ties which can fail over time creating opportunities for wire damage or worse. Spring loaded brackets allow the rail to snap into place and be released, without tools, and easily slide prior to leveling and tightening. SnapNrack doesn’t rely on T-Bolts that can bind or be improperly installed, resulting in a system failure. Roof penetrations are protected with a patented cone flashing feature that extends above the base of the roof attachment and sealed under a proprietary Umbrella Lag.

How does it install: RL-U is designed such that each install step is independent, where a single installer can install the entire system. The roof attachments are a Flash Track which provides North-South adjustability, secured with a single Umbrella Lag through SnapNrack’s patent pending Umbrella Flashing. RL-U only requires a single RL-U Mount SKU, which is used at all locations on the array. The integrated RL-U Skirt attaches to the first row of mounts, creating a strong structure for leveling and aligning the array. The RL-U Links clamp onto the top of modules securing them in place while providing row-to-row bonding, and provide an attachment point for 2-4 modules. A single installer can drop modules into place, and secure them across the top without having to reach down the roof across a module.
Advantages: RL Universal is designed to provide the fastest, most intuitive install experience on the roof. The direct mount system features four basic components, with nothing larger than the size of a module, resulting in easy material management. Features include an integrated Skirt for a secure installation with sleek aesthetics, Universal Mounts used at all locations on the array & Links that can accommodate 2-4 modules. Mount & Link interference is eliminated with the unrivaled Mount offset & Link adjustability. RL-U is the only railless system to offer labor saving installation processes backed by the industry leader in residential solar.

How does it install: SnapNrack SpeedSeal Foot & Track allows installers to lag straight to a structural member with no in-between components, and eliminates damage to shingles from the installation process. The simple install process consists of locating a rafter, filling the sealant cavity and securing to the roof. The SpeedSeal Technology takes over, compressing sealant into the cavity, shingle surfaces and lag hole, as the SpeedSeal Foot or Track is secured to the rafter. The SpeedSeal DeckFoot & DeckTrack mount directly to the deck, making installation even faster by allowing installers to lag straight to the roof deck & eliminating the need to find a rafter.
Advantages: The SpeedSeal Technology portfolio save installers time on the roof with less parts and tools, while maintaining the integrity of the shingles. Metal flashing requires the use of a pry bar to “rip up” the shingles and remove nails. SpeedSeal eliminates this, so the roof remains intact, the way meant it’s meant to be, all while faster. The new SpeedSeal DeckFoot and DeckTrack provide further time savings due to their ability to by mounting directly to the roof deck. Installers no longer need to find rafters and seal missed pilot holes.

How does it install: PV Booster is mechanically attached to flat C&I rooftops. The three major subsystems install fast by torquing our tripod (support system) down to the mechanical attachment (included), bolting on the drive mechanism (actuator), and installing the h-frame (panel support). Panels are then mounted on the h-frame. The system is wired up in strings of 30 or less to our tracker distribution boxes (control hardware) mounted on the rooftops. The 30 degree tilted vertical axis tracker significantly improves energy production and requires about 1’ between panels to allow for a full range of tracking motion to achieve that goal. A small, wall-mounted control computer is installed in the mechanical/electrical room near the inverters to ensure functionality if the site loses internet connectivity.
Advantages: PV Booster brings tracking to flat C&I rooftops to dramatically increase system efficiency with a smaller footprint which significantly reduces the LCOE of your projects. PV Booster allows building owners to use less equipment to produce more energy from every panel. Our systems produce 30-40% more energy out of every monofacial panel. PV Booster is the best mounting solution for bifacial modules as well, producing as much as 70% more energy out of bifacial panel. Produce more with less using PV Booster, rooftop tracker.
