RE+ Trade Show (formally Renewable Energy Plus) is a solar power conference created in 2004 for show-casing new technology when the Solar Electric Power Association (SEPA) and the Solar Energy Industries Association (SEIA) merged to organize an annual event bringing together companies and professionals from the solar industry. In 2008 it was touted as the largest solar power conference in North America. Previously called Solar Power Conference and Expo and later Solar Power International, it consists of two main elements: an exhibition hall where companies have booths to promote their products and services; and conference sessions where panels of solar industry experts share ideas and success stories. The 2018 event included hydrogen and fuel cell technologies. The conference was held virtually in 2020 due to the COVID-19 pandemic and in 2021 due to Hurricane Ida.
Attendees RE+ is attended by professionals in the solar industry including builders, project developers, installers, distributors, engineering firms, investors and financiers, service providers, law firms, equipment manufacturers, software companies, and manufacturers of tools for equipment manufacturing. Representatives from utilities also attend the conference as well as government representatives, policymakers, and the press.
Members of the Solar Energy Industries Association and the Solar Electric Power Association receive discounts on registration.
The majority of attendees of Solar Power International come from the United States, however there are a large number of attendees from major solar markets such as China, Japan, and Germany.
Conference Sessions The conference sessions at RE+ are traditionally separated by topic into different tracks. Typical tracks are technical, marketing & sales, market conditions, finance, and politics. There are generally over 70 sessions over the four-day conference. For the 2026 conference, planned topics include photovoltaics, energy storage systems, hydrogen technologies, microgrids, wind energy, electric vehicle infrastructure, and the digitalization and electrification of power grids. Start-Up Alley, located on the Expo floor, is a dedicated area specifically designed to promote up-and-coming ideas and companies in the solar industry. It was added to the conference features in 2013.
