SunFrame Rail System

Unirac’s SunFrame system leads the PV market with its superior aesthetics. Its sleek design is engineered to sit low to the roof without gaps and implements shared rails for the best value.

SunFrame is also the choice of solar experts as an optimal solution for custom carport structures. It's accompanied by a technical support system that provides complete installation and code compliance documentation, an on-line estimator and design assistance to help you solve the toughest challenges.

Main Components
Attachment Options

SunFrame

Modules are supported between SunFrame rails, not on top of them. The array is lower to the roof, enhancing its integrated appearance. A threaded slot atop the rail makes for quick and secure module mounting.

SunFrame

Shipped in 8- or 16-foot lengths , SunFrame shared rails are a 6105-T5 aluminum extrusion available anodized (clear or dark bronze) to match PV module frame.

L-FOOT ADJUSTING SLIDER

Use this optional aluminum component beneath each L-foot or aluminum two-piece standoff, except in lowest row, for easy alignment of rails to PV modules.

SolarMount S-5

SolarMount/S-5! captures the PV potential of standing-seam metal roofs at the lowest possible installed cost. Clamps don't penetrate the roof. With only two basic components, SolarMount/S-5! clamp sets are easy to install and align, saving time on the job site.

L-Feet

Standard for ground mount installations, L-feet mount rails to residential and commercial rooftops as well. Use them alone above asphalt composition shingles or in conjunction with flat top standoffs.

Standoffs

Use with SunFrame, SolarMount standard, or SolarMount HD rails. Secure to rafter with 2 lag screws. Secure L-foot or installer-supplied strut directly to standoff with standoff hardware. Especially convenient when installing over a tile roof.

FastFoot™

TheFastFoot attachment for SolarMount, SolarMount Light, SolarMount Heavy Duty and SunFrame features Eco-Fasten technology by the Alpine Snow Guard Company. Attach to metal, concrete and wood decks without compromising the integrity of the roof.

Unirac documentation provides the technical information to demonstrate SunFrame’s structural integrity and to ease permitting. Follow our step-by-step procedures to satisfy your building inspector.

Mount SunFrame vertically for a triple benefit: Cladding shades and cools your building, produces PV power, and looks great.

Low and clean lines give SunFrame two advantages. The finished array stands off the roof just enough for cooling air flow to optimize module performance and all modules sit in low, gap-free rows without protrusions from the sides of the array.

Kyocera's award-winning Solar Grove carports used SunFrame to mount a total of 1,400 Kyocera modules and 200 custom-manufactured, light-filtering PV modules over their employee parking lot in San Diego.

Case Study

Case Study: The TriBeCa Green building

SunFrame-mounted modules forms the vertical facade of The TriBeCa Green building in Manhattan. Thirteen rows, each holding 10 SunPower 210 watt PV modules, provide more than 27 clean kilowatts. The New York City installer altPOWER completed the project in August 2005.
