U.S. Bank and PGE have formed SunWay 2, LLC, to own and operate the system and to secure state and federal solar tax credits to help finance the project. The financing package was arranged by United Fund Advisors. Energy Trust of Oregon, a nonprofit organization that promotes energy efficiency and renewable energy, is providing about $1 million in incentives for the project.

Thin-film photovoltaic solar panels are ideal for rooftop installations, as they are lighter, require less structural support and have a higher wind rating than traditional glass laminated and aluminum framed solar panels. The system will be installed by publicly held Solar Integrated Technologies Inc., which has worked with ProLogis on solar energy systems in France and Spain.

ProLogis Park PDX, Building 4, the largest installation site, is located near the intersection of Interstate 84 and Northeast 148th Avenue, approximately five miles southwest of Portland International Airport. The system is expected to begin producing as much as 1.1 megawatts of electricity for PGE customers by December. To date, ProLogis has approximately six megawatts of solar panels installed or under development on rooftops in Southern California, France, Germany and Spain.
