PVKIT® Rail-Less Metal Roof Solar Mount

The Direct-Attach™ Solution for Standing Seam and Exposed-Fastened Metal Roofs

PVKIT Brochure

Getting project materials to the jobsite and onto the roof are often considered unavoidable costs associated with solar mounting.

It costs money every time you have to move materials and/or equipment. What if you could greatly reduce the weight and volume of your solar system? 

Using the PVKIT can save you up to 50% in:

  • Hardgoods - For example, a 50kW system requires about 150 lbs. (68kg) of parts vs. 970 lbs. (440kg) of rail.
  • Shipping - 80% lighter weight than rail mounting. Fewer than 3.5 lbs./kW (1.6kg) vs. 19.4 lbs. (8.6kg/kW) for rails.
  • Material transportation to the site - The 50 kW system delivers to the jobsite in the trunk of your car.
  • Lifting equipment not needed -  Equipment is only necessary for projects more than 500kW.
  • Installation time and cost - Locate modules as desired without customizing rails. Installation time is 30-50% less.
  • Aesthetically pleasing - Assembly is available in black architectural anodizing.

Your Metal Roof Already Comes With Rails for Solar Mounting - Why Pay Twice?

Using the roof’s integrated “rails” makes solar mounting quick and convenient. Compared to rail mounting, the PVKIT:

  • reduces the weight of the mounting system by 85%
  • provides 25% better load distribution
  • uses 70% fewer components
  • lowers material costs

With total mounting system weight below 3.5 lbs./kW (1.6kg)/kW compared to 19 lbs. (8.6 kg)/kW for railed systems, the savings in transportation costs and logistics is tremendous. The solar zone layout is more flexible. The added load to the building structure is far less. Material handling is reduced and simplified with only 3 components for the mounting system. Electrical bonding is automatic. “Lay and play” installation saves time on the roof.

PVKIT Works for the Following Roof Type:




Standing Seam



PVKIT Components

PVKIT MidGrab Assembly (Includes PV Disk)

Used between adjacent modules to attach both frames to a single connection point. The MidGrab can also be used as an edge condition if desired.

PVKIT EdgeGrab Assembly (Includes PV Disk)

Used at edges of array to attach modules to rooftop clamp or bracket leaving a clean finished look.

PV Disk (included with PVKIT)

Structural platform between module frame and clamp or bracket, which performs multiple functions. Bonding teeth abraide anodization creating a continuous electrical path along module columns. Slotted holes at the edge of the disk act as attachment locations for wire management ties.

Compatible S-5! Mini Clamp

For use on standing seam profiles. See individual pages to select the best attachment solution for your metal roof profile.

(Pictured: S-5-E Mini. Visit our clamp overview page to view additional attachment solutions.).

Compatible S-5! Bracket

Attachment for exposed-fastened roofing. See specific product pages for critical dimensions to ensure correct bracket selection.

(Pictured: ProteaBracket™ for exposed-fastened, trapezoidal rib metal roofing. Visit our bracket overview page to view additional attachment solutions.) 


EdgeGrab and MidGrab Assembly available in architectural anodizing (w/ aluminum PV Disk). 


How to Install the PVKIT on Your Roof Profile*

Install the first row of S-5! clamps or brackets at the edge of the array. Mount the PV Disks and the EdgeGrab/standoff assembly to the first row of clamps. Install the first row of modules. Then install the MidGrab/standoff assembly & PV Disk on clamps or brackets. Place MidGrab/standoff/disk & clamp assemblies. Install additional PV modules.
