The 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.

The State of Hawaii, Department of Transportation, Airports Division has partnered with REC Solar to install roof mounted photovoltaic systems at their two largest facilities–Honolulu International and Kahului Airports. The Hawaii Clean Energy Initiative, in conjunction with the State of Hawaii and The US Department of Energy, have set goals to achieve an astounding 70% clean energy by 2030. These are the most aggressive renewable energy goals in the US. Not only will this achievement rank Hawaii as a world leader in renewable energy, but will also function to stabilize and increase the independence of their local economy. Sollega is proud to participate on these projects.

The new FastRack510 (FR510) was selected to mount a total of 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 simple and i n t u i t i v e i n s t a l l a t i o n procedure. The non-corrosive Ultramid® material, and Sollega’s proven engineering made this competitively priced mounting solution even more attractive for the 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. The 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 wiremanagement system and high roof clearance made stringing modules and performing home runs just as simple and fast as installing the modules.
