PV Panel height from roof
Typical Bifacial Gains Observed
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

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.
