S-5! PVKIT® 2.0 Rail-less Solar Mounting System

Mount solar modules faster, cheaper, and smarter with the S-5!® PVKIT® — the original rail-less solar mounting solution for metal roofs. By using the roof's existing seams or ribs as the mounting structure, PVKIT eliminates the need for bulky rails, cutting your material costs, installation time, and project headaches. Whether you're working on standing seam or exposed-fastened metal roofs, PVKIT delivers a streamlined, lightweight system that’s engineered for speed, strength, and simplicity.

  • Faster, Easier Installation

    Pre-assembled components, automatic electrical bonding, and one-tool installation slash labor time by 30-50%. Installers can quickly locate modules without worrying about rail alignment, resulting in quicker, more flexible layouts.

  • Direct-Attach

    PVKIT mounts solar modules directly to the roof's seams or ribs — no need for traditional rails. This cuts down on materials, reduces system weight by up to 85%, and simplifies logistics. Less to buy, less to carry, less to install.

  • Universal Compatibility

    PVKIT works with nearly any metal roof. Pair it with any S-5! clamp (for standing seam) or bracket (for exposed-fastened panels). It accommodates module frames from 30-46mm and is available with an optional black architectural finish for a clean, professional look.

PVKIT 2.0 FAQ

What type of roofs can I use the PVKIT on?

PVKIT works on most metal roofs — standing seam or exposed-fastened. Just pair it with the correct S-5! clamp or bracket for your specific roof profile.

How much weight does the PVKIT system add to my roof?

Less than 3.5 lbs. per kilowatt. Compared to traditional rail systems that often exceed 19 lbs. per kilowatt, the PVKIT keeps your roof load light and manageable.

Will using PVKIT void my metal roof warranty?

Nope. S-5! attachment solutions are designed to work without compromising roof warranties, when properly installed.

What size solar modules does PVKIT support?

PVKIT is adjustable and fits module frames from 30mm to 46mm thick, making it compatible with most common solar panels.

Can a homeowner install PVKIT themselves (DIY)?

Yes — if you're comfortable working safely on metal roofs and have basic solar installation knowledge. The PVKIT is simple by design, with pre-assembled parts and a one-tool install, but you'll still need to properly handle electrical connections and follow all code requirements. Many homeowners team up with a licensed electrician or solar pro for final wiring and inspections.
