Overview
Sollega is proud to have partnered on the 1.33 MW solar PV ballasted / hybrid flat-roof installation at Harvey Milk Terminal 1 at San Francisco International Airport. The installation had strict requirements due to the terminal's sensitive location and its role in SFO's LEED Gold certification effort. The system is projected to generate over 2.2 MWh of electricity per year.
SFO's rooftop PV project posed unusual challenges, including exposure to corrosive jet-exhaust emissions, complex drainage slopes, and more than 24 inches of roof insulation. The first phase began pre-COVID and paused alongside terminal construction during the pandemic; the build resumed as soon as construction resumed.
The FR510-6dg, crafted from BASF Ultramid Nylon 6, provided the ideal solution to this complex installation. Known for resistance to corrosion and environmental stress, the high-performance polymer kept the racking durable in the harsh airport environment. The FR510-6dg's modular, roof-friendly design, combined with non-penetrating U2000 anchors, accommodated the thick insulation and drainage slopes to deliver a low-maintenance PV system engineered for long-term performance.
