S-5! PVKIT 2.0 Case Study – Calcaire House

 

“The Solar Revolution has been utilizing the S-5! PVKIT solution since it first hit the market. Hands down, it is the best solar mounting solution for metal roofing of any description. At first, we were a little worried about wire management and installing in landscape, but those worries were overcome with our first installation. It’s a piece of cake.

Our projects using the PVKIT yield the fastest installation times, lowest material cost and best aesthetics bar none. We’ve taken a close look at all the competitors’ knock-offs, and they do not compare in quality or even in cost. S-5! has been creating innovative solutions for metal roofs far longer than anyone else, and their expertise is unmatched. We just won’t use anything else on a metal roof. These guys are awesome, and I’ve enjoyed working with their staff on various projects. They tell it like it is and have always treated us like part of the S-5! family.”

The Project

The Calcaire House is a 15,000-square-foot modern Colorado single-family residential compound consisting of five interconnected buildings.  Floor-to-ceiling glass connects the interior space to the exterior landscape, offering spectacular views of the Boulder Flatirons. A combination of exposed timber, stone and steel structural design elements, and exposed custom roof trusses complement the gabled standing seam metal roof.

The Solar Revolution was charged with installing more than 60 kilowatts of solar dispersed over multiple rooftops. Boulder Roofing installed both standing seam metal and TPO roof systems.

The Challenge

The City of Boulder has strict energy codes in place and requires new construction to meet a certain level of efficiency. The goal is to have a net-zero home, and the only way for a larger home to achieve this is with solar.

The most optimal rooftops for solar were also the most visually prominent, and the homeowner was concerned about aesthetics.

Furthermore, this area is considered a high-wind area and would require a study to account for wind speeds as the solar installers could only rely on the roof itself and its attachment to the wood sheeting when attaching solar panels using S-5!’s zero-penetration system.

Another difficulty was finding a viable path to route the energy created by the solar panels back to the point of connection with the home’s distribution. The Solar Revolution ultimately found a viable path that was aesthetically pleasing, code compliant and cost-effective.

The Solution

Installers utilized the S-5-PVKIT® 2.0 to build the solar array. One team member started at ground level prepping S-5! MidGrabs and EdgeGrabs, while another prepared the solar modules by installing the power optimizers and managing the wires.  Completing this work on the ground enabled the roof crew to focus on setting modules – minimizing their time in harnesses.

The team installed the modules starting with the bottom row and working up, with extra care taken in aligning the first row.  This precision allowed for subsequent rows to drop into place on the MidGrabs.
