Solar Power International is the largest solar trade show in North America. Join over 18,000 attendees from over 110 countries. The premier event in the industry features over 24 hours of networking events, multiple education tracks, and hundreds of speakers. SPI is co-located with North America’s largest storage trade show, Energy Storage International (ESI), and Europe’s largest hydrogen trade show Hydrogen + Fuel Cells North America. You can visit all these exhibitions, including the Smart Energy Microgrid Marketplace, in the exhibit hall. Unlike other solar conferences, all proceeds the event support the expansion of the solar energy industry through SEIA and SEPA’s year-round research and education activities, and SEIA’s extensive advocacy efforts.
