SunTilt™ Metal

SunRail Universal (SRU) Bifacial Solar PV Racking System for tilted roof

Ce

Key specifications

Material

100% aluminum structure and components, stainless steel bolts & nuts.

Max Snow Loads

Can be designed for any snow loads (up to over 100 PSF)

Max Wind Loads

Can be designed for any wind loads (up to 180MPH)

Tilt Angle

10 to 30 (5 deg. increments)

PV Panel Orientation

Landscape

Module

Any framed PV, any frameless PV

Tilted Roof Attachment

100% direct attachment (lag bolts, hanger bolt, standing seam clamps, corrugated metal roof SMC Clamp)

Unique Patented Solution

Corrugated Metal Roof (Barn Roofs) can use Opsun's unique patented SMC clamp (CA 2751963) that reuses the existing screw hole in the metal roof, and attaches in the strapping, for easier installation.

Dead Loads on roof

2-3 PSF

PV Panel height from roof

Customizable, starts at 8 inches

Grounding

Self-bonding PV clamps, UL 2703 listed

Typical Bifacial Gains Observed

10-25% (N-Type, on white metal roof. Must be optimized per project, not a guarantee.)

Increase yield with a racking optimized for bifacial PVs

Instead of placing panels flush on tilted roof, Opsun SunRail BifacialTM allows to place the panels at an angle on the tilted roof, allowing for better natural cleaning and increasing significantly yield by adding bifacial gains. Open design allows for easy roof access for maintenance, and lower PV operating temperatures.

Designed to boost performance of Bifacial PVs

No wind deflector, high tilt and high elevation possible, extra long interrow distance possible. All rails on the edge of the PVs, not under them. The Opsun SunRail Bifacial™ can be adapted to maximize the amount of light the backside of the panels receive. Optimal for fully anchored system, for maximum irradiation of the backside of bifacial PVs.

Complete turn-key engineering services

Our experts will support your project, offer expert advices on how to get maximum performance from bifacial PVs, help optimize layout, tilt angle and panels elevation from roof. We can find solutions to most construction challenges, and design custom solution for almost any building, of any shape and height.

Advantages

Any type of tilted roof

Our engineers can find solutions to any complex engineering challenges, building structures with one, two or three layers of rails, as needed, to allow attaching to the building's structure.

Better Panel Protection

Strong rails supporting PVs on their full length help prevent torsion and movement that leads to accelerated degradation of PV panels

Full Aluminum Design

Rail-based design with 6000 series aluminum and 304 stainless steel bolts and nuts guarantee maximum durability of the structure for decades.

UL 2703

ETL listed (#5013658) to UL 2703, for all configurations except 5 deg. Tilt.

Fully Adjustable System On-Site

All components can be slid in the rails' channels, to adjust for roof unevenness. System will follow roof's drains, crikets and tapered insulation with ease.

Typical Overall Racking Installation Speed (including PV panels' DC connection)

4000 + W/ man-hour (preassembled), 1700-2000 W/man-hour (disassembled).

Highest Standard for Engineering & Support

Our engineers use only the safest methods of calculation, to assure maximum solidity and durability of the structures. We have proprietary, recent wind tunnel tests with Western University, and we design using the latest Building Codes (ASCE-7-16, NBCC 2016, IBC 2018), as well as SEAOC PV2 notions of array size versus roof size to account for extraordinary vortices. Minimal deflection allowed on rails, and finite element analysis done with high-end 3D engineering software. Each zone ballast & anchors calculated individually. We find solutions to each unique challenge, and we react quickly if unforeseen events happen during construction (such as unmarked drains, roof equipments obstruction and last minute changes).

Project-Specific Building Permit Plans & P.Eng stamp with each project

Custom, project-specific building permit plans, stamped by a local P. Eng., are provided for each job, describing step-by-step where each component goes, on the exact project site, with markups, details and explanations custom to each project's specific difficulties.
