S-5! PVKIT™ 2.0 Solar Solutions
S-5! now introduces a new and improved PVKIT, boasting lower installation time and cost for PV flush-mounting. The kit comes preassembled with MidGrab or EdgeGrab for easier and more efficient installation. A single tool drives the top bolt, eliminating several installation steps. The PVKIT 2.0 features more aggressive bonding teeth for better grounding. Fewer lugs/ground wires required.
New from the metal roof experts: The S-5 PVKIT 2.0 is designed to save you time and money.
The Module Placement Bevel Guide makes the module placement easier. The mounting disk is multi-directional and rails are not required. The PV grab ears are broader for ease of installation and secure module engagement.
PVKIT fits a wide array of module thicknesses. Use with S-5! mini clamps enables fitting to all standing seam metal roof profiles of any material. When paired with other S-5! products, the PVKIT 2.0 also works on all trapezoidal ribbed and corrugated metal roofs.
The MidGrab can also be used as an edge condition if desired.
Modules can be easily installed from ridge-down or eave-up.
More slots for wire securement.

Suggestions for Spacing of S-5! Clamps for PV Assemblies
The following suggestions assume that determination has been made that the roof to which the S-5! clamps will be attached is structurally adequate. Any loads imposed on the S-5! clamps will be transferred to the panels. Panel seams must have sufficient flexural strength to carry these loads. Panels must also be adequately attached to the building structure, and the structure must be sufficient to carry these loads. The makers of S-5! clamps make no representations with respect to these variables. It is the responsibility of the user to verify this information, or seek assistance from a qualified design professional, if necessary.
The key to frequency and spacing of attachment points for PV is to distribute loads to the metal panels in a manner that is consistent with the intended distribution of loads from the roof panels into the building structure. With very few exceptions, the attachment of a single S-5! clamp (even the “Minis”) to the seam will be stronger than a single point of attachment of the seam to the building structure. Hence the “weak link” is not the S-5! clamp, but the attachment clips that hold the metal panels to the building structure, or the beam strength of the roof panel seam itself.
Whether utilizing rail or Direct-Attach™, the best approach for the PV attachment to the standing seam roof is to populate points of attachment so that the wind uplift loads experienced by the modules are distributed evenly into the roof below. This reduces “point loads” to the roof panels to a tolerable level. Most pre-engineered metal buildings utilize roof panel attachment to the structure every 10 sq. ft. So how often should rails be attached? No less than once for every 10 sf of roof surface. The same is true for Direct-Attach™. Most 60-cell modules are ≤18 sq. ft. in surface area. By utilizing the four module attachment zones as directed by module producers, and attaching the module directly to the roof seam, the resulting tributary load area to each point of attachment is ≤9 sq. ft. Such an attachment scheme should evenly distribute wind loads into the building structure through the panels and their attachment, as was intended in the original roof construction assembly.
Note: Wind dynamics are complex, and S-5! advises review by a qualified professional who understands wind effects and as well as metal roof design and construction.
