Opsun releases third generation of rail-based bifacial solar racking for flat roofs

Canadian solar company Opsun has unveiled a new generation of rail-based bifacial solar racking for flat commercial roofs.

This upgraded third generation racking system called the Sunrail SR3 now includes fewer parts and requires even less tools to install.

“Rack system failure is the most unspoken problem in the rooftop solar industry,” said Alex G.-Vanasse, VP Business Development at Opsun Systems. “Poorly designed systems fly away from low quality roofs and racks rust and become unable to hold solar panels over time. All these problems are not secrets, and yet there are currently few solutions on the market to solve them at an affordable price. “

The Sunrail SR3 is an aluminum rail-based system that meets the latest American (ASCE-7-16) and Canadian (NBCC 2015) standards. The system uses the company’s Opsun MESHTM Technology approach that creates an ultra-detailed Finite Element Analysis (FEA) network simulated with hundreds of load cases for each configuration.

Like previous generations, the Sunrail SR3 is supposed to maximize bi-directional energy gains and not cast shadows on the back of the solar panel. To maximize light uptake under and behind bifacial solar panels, the Opsun SR3 can be designed with high tilt angles (10 ° to 30 °) and can be adjusted to have a large clearance so that it is above most roof obstructions.

The Sunrail SR3 does not require wind deflectors, which makes the installation even faster and the operating temperature of the solar panels drops.

“Opsun leveraged two decades of solar expertise to achieve a massive weight reduction of the Sunrail SR3’s solid aluminum skeleton without any compromise on structural strength,” said François Gilles- Gagnon, President of Opsun Systems. “The resulting product is a best-in-class bifacial solar panel rack that is stronger, at an affordable price, and powered by the industry’s most advanced computer-aided engineering process – Opsun MESHTM technology.”
