Sunground™ Seasonal

SunGround Bifacial, a universal Ground Mount PV Racking System


Key specifications


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

0 to 90D (typical 30-55 deg.)

PV Panel Orientation



Any framed PV, any frameless PV

Foundation Type

Any (helical piles typical, can be designed on concrete footings or driven piles of any shape)

PV Panel height from ground

Customizable, typically 36 inches

Variable Tilt

Possible (up to 3 positions, manually changed for seasonal adjustment)


Bonding jumpers available, UL 2703 listed

Typical Bifacial Gains Observed

10-15% (N-Type, on grass. Must be optimized per project, not a guarantee).

Designed to boost performance of Bifacial PVs

All rails on the edge of the PVs, not under them. No component blacking the backside of the panels. The Opsun SunGround Bifacial™ system is designed to maximize the amount of light the backside of the panels receives.

Freedom of design

Our experts can create any groundmount design as per your requirements : any number of panels high and across, portrait or landscape, at any tilt. Can easily be engineered for hurricane or extreme snow regions. Typical commercial applications are four (4) 72 cells PVs vertically (landscape) by four (4) or eight (8) across (horizontally).

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 ground. We can help design foundations on any soil type (soil study required, by others).


Fast installation with light components

No crane or heavy lifting equipment necessary, all rails can be mounted by hand. On-site adjustments possible using rails' channels. Faster installation than most steel-based systems.

Fewer Posts per Structure

Our team of expert optimize each system to minimize the number of foundations required. Up to eight (8) 72 cells panels per foundation.

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. Great for coastal regions.

UL 2703

ETL Listed under UL2703 for all configurations

Fully Adjustable System On-Site

All components can be slid in the rails' channels, to adjust for roof unevenness. Up to 2" in all direction of adjustment if foundation (posts) are not perfectly strait or improperly positionned.

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

5000 + W/ man . Hour (preassembled), 2000 + W/man . Hour (unassembled). Depends on configurations.

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. Minimal deflection allowed on rails, and finite element analysis done with high-end 3D engineering software. Each component and vertical structure calculated individually. We find solutions to each unique challenge, and we react quickly if unforeseen events happen during construction (such as terrain obstructions 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.
