Modular Tackles Tough Roofs and High Costs

July 15, 2014

SunLink has just introduced Precision-Modular RMS ― the newest addition to our quality engineered, aluminum Precision RMS racking family. The new system is available for 60 and 72-cell modules and 10 degree tilt. LinkUp sat down with VP of Products and Strategy, Yury, to learn a little bit more about the new roof mount design.

“The products that make up the Precision RMS line advance distributed generation by making solar viable for a much larger range of rooftops – even in locations where it wasn’t previously possible,” explains Yury. “The inaugural Precision RMS product achieved that by making it possible to install solar on roofs with weak decks and in high snow zones. Now, our new Precision-Modular RMS product solves the challenge posed by rooftop obstructions. The system is assembled, laid out and installed module-by-module to maximize layout flexibility and facilitate last minute on-roof changes.”

In addition to superior layout flexibility, Yury says that Precision-Modular will offer the industry unrivaled value without sacrificing the product quality and engineering excellence for which SunLink is best known.

“Precision-Modular is the most cost effective mounting system in our company’s history. We’ve engineered it across the board to ensure a lower total installed cost. First, we maintain the system components as part of a standard inventory, which allows us to keep costs down and shorten delivery times. But that’s just the beginning. As with all SunLink roof mount products, the system includes integrated wire management and grounding to make many ancillary electric components unnecessary, and features roof-friendly rubber feet that prevent any metal from touching the roof surface to eliminate the need for slip sheets in most cases.”

Yury adds that Precision-Modular leverages a fool-proof jig that is made using an actual project module to auto-align and auto-space all components perfectly – no measurement required. This approach increases installation throughput and improves overall quality, and as a bonus, also allows module-to-hardware assembly to take place at waist height in a controlled environment.

“At the same time, the system is fully connected north/south and east/west to better distribute loads, and does not rely on the module frame as a structural element,” Yury adds. “Customers who have come to rely on the high quality, sturdiness and precision engineering SunLink offers will be pleased to find another system that lives up to their standards.”

Yury and I wrapped up our conversation by talking about row spacing as it relates to both project density and O&M.

“Precision-Modular allows for density optimization based on latitude and/or customer preference,” he explained. “Plus, the design’s compact deflectors and hidden ballast makes it easy for crews to maneuver between rows both during the installation process and for purposes of ongoing O&M activities.”

The deflectors and under-module-ballast placement also helped Precision-Modular become one of the first roof-mount systems to earn UL’s 1703-2013 class A fire classification rating.

After our chat, Yury showed us how the Precision-Modular building block design is so lightweight and easy to install that it can be assembled by one person. The jig made it simple enough for even this blog author to build a small array. For your own hands-on demonstration, contact your SunLink sales rep or email
