Solar Power International is powered by the Solar Energy Industries Association (SEIA) and the Smart Electric Power Alliance (SEPA). SPI held its inaugural show in 2004 and was designed to serve and advance the solar energy industry by bringing together the people, products, and professional development opportunities that drive the solar industry and are forging its bright future.
The Oregon Solar Energy Conference is the nations best regional solar conference. In 2018 we hosted over 430 attendees representing over 170 companies. We had over 30 exhibitors and sessions ranged from technical training to business training to solar policy. Join us in 2019 for another amazing event.
