Mounting manufacturer Sollega provided its FastRack510 (FR510) to mount 8,148 Trina and JA Solar 72-cell PV modules.
The airports division of the Hawaii Department of Transportation has partnered with REC Solar to install roof-mounted PV systems at Honolulu International and Kahului Airports. The installations help support Hawaii Clean Energy Initiative’s goal to achieve 70% clean energy by 2030.
Mounting manufacturer Sollega provided its FastRack510 (FR510) to mount 8,148 Trina and JA Solar 72-cell PV modules. The one-piece FR510 requires no assembly, and it’s universal design allowed REC to install four different models of PV modules with the same installation procedure.
The system’s non-corrosive Ultramid material is beneficial tropical and costal region. The high array density of the FR510 allowed the DOT and REC to meet their production goals.
The airports are not only in hurricane prone regions, but also in areas of high seismic activity. Minimal seismic anchors were installed at a rate of up to five per man hour.
Combined, the arrays were spread over more than ten individual flat roofs. Many of the roofs were tiered, making it difficult in some cases for the crew to move equipment to the upper levels. While the FR510 was easily staged, Sollega’s engineering team was able to keep the ballast to a minimum to reduce this inherent inconvenience.
As one of the nation’s leading commercial solar integrators, REC has extensive experience in Hawaii, as well as with installing the FastRack mounting system. They were able to stage and install the mounting system quickly and easily.
Sollega’s flexible wire management system and high roof clearance made stringing modules and performing home runs just as simple and fast as installing the modules.
