S-5-PV Direct Attachment Solutions

S-5! introduces the new and improved version of its popular S-5-PV Direct Attachment Solutions. The kit is designed specifically to secure framed photovoltaic modules to standing seam metal roof systems without penetrating the roof surface. S-5! has created a solution for the PV industry that:

  • Fits the majority of metal roofs on the market—including exposed-fastened and corrugated
  • Installs quickly and easily
  • Universally fits both field (2 panels) and end conditions
  • Cools roofs by providing shade during intense summer heat, lessening utility costs
  • Can be used with all S-5! Mini clamps; use the stainless steel mounting disk to facilitate use with brass clamps
  • Costs as little as $0.07 a watt (stainless steel mounting disk) or even $0.06 a watt (aluminum mounting disk) to install

The concept of combining photovoltaic arrays with standing seam metal roofing is growing—and for good reasons. A standing seam metal roof has a life expectancy consistent with that of framed PV modules. A 30-year power source on a 40-year roof, along with zero-penetration technology creates the most sustainable roof system available with alternative power generation, all without compromising the roof’s warranty!

  • New, longer PV stud now accommodates PV frame thicknesses from 1.3″ (33 mm) to 2.5″ (64 mm)
  • Beveled mounting disk now provides an even easier-to-use module placement guide
  • Four new, strategically placed mounting disk hooks to assist in wire management
  • New, broader ears on the PV grab allow for even easier installation and precise module engagement
  • Mounting disk is universally directional for simplicity of installation
  • Absolutely NO rails required
  • Incredible holding strength that only S-5! can offer

Penetration-free attachment, lower installation costs and cooler roofs, combined with rising energy costs and increased environmental concerns all spell a bright, sunny future for PV and standing seam metal roofs. And, S-5! makes it easy.

The design of the attachment clamp and attendant round-point setscrews enable an entire installation without a single penetration through the roof’s surface. Installation is quick and easy, and costs can be as low as $0.06 a watt. The new S-5-PV Direct Attachment Solutions fits only S-5! Mini clamps, NOT standard clamps. The PV Kit can also be used with VersaBracket™ and CorruBracket™.

The new S-5-PV Direct Attachment Solutions works perfectly with our CorruBracket, and a flat mounting disk is available for using the S-5-PV Direct Attachment Solutions with our VersaBracket, allowing solar panel attachment to exposed fastened and corrugated metal roofing!

The Basic Components

The S-5-PV Direct Attachment Solutions fits two grab components. The universal PV grab attaches adjacent panels, while the EdgeGrab™ cleanly resolves end condition requirements.


Note: Due to the variety of attachment needs, S-5-PV Direct Attachment Solutions are sold separately from S-5! Mini clamps. The S-5-PV Direct Attachment Solutions fits only S-5! Mini clamps, NOT standard clamps.

The new S-5-PV Direct Attachment Solutions is one of the first solar module mounting solutions in the industry to be listed to the new UL Subject 2703, a standard that covers both bonding and mounting. In order to meet the UL requirements, the S-5-PV Direct Attachment Solutions had to be submitted for tests, being evaluated under the severest of conditions to confirm that the product would withstand the elements while maintaining electrical conductivity.

Furthermore, the S-5-PV Direct Attachment Solutions has gained an ETL Listing to UL 1703. UL and ETL listings are widely recognized by most Authorities Having Jurisdiction, which means fewer inspection hassles for installers.

Previously, electrical continuity between modules (called “bonding” within the industry) required the mounting of an electrical lug to each PV module, and interconnection of the lugs with a copper wire. However, the S-5-PV Direct Attachment Solutions’ groundbreaking NEW stainless steel mounting disk has twelve nodes designed to ensure the module-to-module conductivity of anodized aluminum module frames.

With the new S-5-PV Direct Attachment Solutions, the module is simply anchored with the kit and automatically provides a ground path in the module frame. No lugs or wire required except to connect one string of modules to another and to ground the system. This connection detail represents installed electrical cost savings of $6-$12 per unit.

In most cases, the savings in time and materials is sufficient to pay for the entire S-5-PV Direct Attachment Solutions and clamp setup! The S-5-PV Direct Attachment Solutions continues to be the easiest, most cost-effective way to install solar panels directly to standing seam metal roofs and remains the most popular choice worldwide: mounting hardware as low as $0.07 per watt; aluminum disk mounting hardware as low as $0.06 per watt!


Introducing The Ultimate Solution For Solar Array End Conditions…



S-5!’s new EdgeGrab is specifically designed to be used in conjunction with our S-5-PV Direct Attachment Solutions for solar array end conditions.

EdgeGrab accommodates PV frame thicknesses of 30–48 mm (if the L-flange is positioned below the stud’s hex nut) and 34–51 mm (if the L-flange is positioned above the stud’s hex nut).

EdgeGrab uses the same S-5-PV Direct Attachment Solutions base assembly as the universal PV grab and will work on most exposed-fastened and corrugated metal roofs.

(EdgeGrab is not UL or ETL Listed.)


Note: Wind dynamics are complex; thus, each system should be reviewed by a qualified licensed professional who understands wind effects on metal roof design and construction prior to purchase and installation.
