Sunrail SRL

SunRail Lite (SRL), a universal titled roof PV racking System

IntertekCe

Key specifications

Material

Aluminum rails and components, stainless steel bolts & nuts. Vertical structure typically in galvanized Steel H-Beams.

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

Flat (Typical), 5-30 deg. (tilted panels on tilted roof possible)

PV Panel Orientation

Landscape or Portrait

Module

Any framed PV, any frameless PV

Roof Type

Any roof type (Asphalt, corrugated metal (barn), standing seams, all other custom roof)

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 4 inches

Grounding

Self-bonding PV clamps, UL 2703 listed

Freedom of design

Our designers and engineers can create a tilted roof racking as you envision. Typical designs can be flush (0 deg. tilt), or tilted at 5 to 30 deg., landscape or portrait. Any common roof type. Structure can be one, two or even three layers to accommodate any construction type.

Create elegant structures

Our experts can help create a visually appealing structure that will not rust. Our racking can integrate seamlessly into architectural projects. Gap between modules can be closed. Rails available in any anodization color, as required.

Complete turn-key engineering services

Our engineers will review the building's roof plans and create a custom structure that matches the roof design, and any other project requirements. We provide detailed, project-specific plans that details installation steps. We can provide a P. Eng. Stamp for all U.S. states and Canadian Provinces.

Advantages

Fewer roof penetrations per PV

Compatible with any standard roof attachment method (lag bolts, hanger bolt, thread rods, standing seams clamp, such as S-5!tm, etc.). Our engineers will find the best attachment method, custom for your project, and the solidity of our racking allows to reduce the number of roof attachments to the maximum.

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

6000 series aluminum and 306 stainless steel bolts and nuts guarantee maximum durability of the structure for decades.

Fully Adjustable System On-Site

All components can be slid in the rails' channels, to adjust for roof unevenness.

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

2900 + W/ man . Hour

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.
