Roof Type Compatibility
Freedom of design
Opsun SunRail ™ is a versatile platform, not a fixed product : we can design a rack at any tilt, any height, any interrow distance, with any PV module, framed or frameless, landscape or portrait. Open design allows for easy roof access for maintenance, and lower PV operating temperatures.
High Tilt, High Elevation possible
Opsun SunRail ™ is one of the rare product to allow tilts up to 30 degrees and elevation from roof up to 24" (610mm) at the front in almost any location on the planet. Open design without wind deflector allows for easy roof access for maintenance, and lower PV operating temperatures.
Great for High Rise Buildings
Fewer ballasts and anchors per PV
Better Panel Protection
Perfectly Safe for the roof
Full Aluminum Design
Fully Adjustable System On-Site
Typical Overall Racking Installation Speed (including PV panels' DC connection)
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.
