Stion's frameless CIGS PV modules installed at San Francisco Airport

Stion Energy Services, the project development arm of Stion Corp of San Jose, CA, USA, has completed the installation and commissioning of a 172kW commercial rooftop solar array on the 78,000ft2 West Field Cargo Building, which is the newest commercial building at San Francisco International Airport (SFO). The array is expected to generate 281,128kWh of energy annually and enable LEED (Leadership in Energy and Environmental Design) Gold Certification for SFO's West Field Cargo Building. Stion Energy Services completes solar installation at SFO airport.

Stion Energy Services says that its turn-key solar solution was selected by Hensel Phelps Construction Co through a competitive bid process, in which it was able to demonstrate the overall best value for the project through a combination of offering the highest level of energy production at the most competitive cost. 

The West Field Cargo Building did not have a roof facing 180° due south, but Stion says that its CIGS (copper indium gallium selenium) technology generates ample electricity even when the sun's rays do not hit the panel at an ideal perpendicular angle (one of the reasons why its solar system was selected for the project). Stion also utilized a Sollega ballasted roof mount in conjunction with Advanced Energy string inverters.

"We expect SFO to see an attractive return on investment over the lifetime of the solar project," says Stion Energy Services' CEO Jeffery Cheng. "Whereas traditional silicon panels generally incur higher degradation levels that quickly reduce power output, the lower degradation factor of the Stion solution will keep production levels more constant over the lifetime of the system," he reckons.
