Developed by the nation’s leading solar energy organizations, the Smart Electric Power Alliance (SEPA) and the Solar Energy Industries Association (SEIA), RE+ reflects an ongoing entrepreneurial approach to renewing best practices across the clean energy landscape as the marketplace evolves.

RE+ held its inaugural show as “Solar Power International” in 2004 to bring together the people, products, and professional development opportunities that drive the solar marketplace.The event has since evolved alongside the industry, bringing together an extensive alliance of clean energy leaders to become the largest gathering of energy professionals in North America. Today, the multi-day event boasts 27,000+ professionals from all segments of the industry, over 800 exhibitors, and 100 countries.
