Solar Power International (SPI) generates success for energy professionals and the global solar industry. SPI sets the standard for solar events as the fastest growing and largest solar show in North America as recognized by Trade Show Executive and Trade Show News Network. SPI has also been among the Gold 100 for eight years running and named this year's "Best Use of Technology" and the 2016 "Stickiest Show Floor" by Trade Show Executive for the innovative ways in which attendees stay engaged. Under the umbrella of North America Smart Energy Week, SPI's expanded scope reflects the growth of energy innovation through the addition of Energy Storage International (ESI), Hydrogen + Fuel Cells North America, and the Smart Energy Microgrid Marketplace.
