In Summer 2009, Portland Public Schools (PPS) completed the first large-scale solar project undertaken by a public school district in Oregon. In conjunction with a re-roofing project at nine schools, PPS installed 5,565 solar photovoltaic thin-film modules on nearly 130,000 square feet of roof. The project was developed in partnership with Gerding Edlen Sustainable Solutions, with design and construction by Northwest Solar Solutions.
