Overview
Sollega has a long history of projects on the Hawaiian islands — including Honolulu and Kahului airports and the Kona Village Resort — where the non-corrosive FastRack 510-6dg thrives in the rust-prone, salt-heavy island climate. That track record was the deciding factor for the string of Home Depots that supply the islands, and Sollega was selected again to supply racking for 4,302 modules across three Home Depot locations in Kailua-Kona, Kapolei, and Kahului.
The one-piece FR510 requires no assembly and is made in the U.S.A. from glass-reinforced nylon Ultramid material, so the racking is uniquely suited to the salt-heavy, humid Hawaiian climate. Beyond environmental exposure, the project sites posed structural challenges: all three buildings sit in hurricane zones and areas of high seismic activity. Combined with Sollega's engineering support, the system delivered a durable, cost-effective solution in a region where rust and wear are constant threats.
The FR510-6dg's high array density helped maximize energy yield at each store, while rapid deployment kept disruption to retail operations to a minimum. Store-level capacity broke down to 499.50 kW-DC at Kapolei, 539.46 kW-DC at Kailua-Kona, and 552.78 kW-DC at Kahului.
