Dynamic three-day event facilitated impactful connections among thousands of solar + storage professionals

Intersolar & Energy Storage North America (IESNA), the premier tradeshow and conference series for solar + storage professionals, kicked off its 2025 event series with its flagship conference and expo last week in San Diego, California. This year's event brought together nearly 500 exhibitors and more than 9,000 visitors.

"Reflecting on the learning, networking, and dealmaking I witnessed at IESNA last week, I'm encouraged," said Wes Doane, Vice President of Intersolar & Energy Storage North America. "Solar + storage professionals from the U.S. and beyond made it a priority to convene at this critical time to discuss challenges and find new opportunities—together. As event organizers, this type of collaboration is our top goal and we couldn't be more grateful for the energy and engagement we experienced onsite."

2025 Event Highlights

IESNA drew diverse participation with attendees representing 59 countries and all 50 U.S. states, as well as Washington D.C. and Puerto Rico—creating a global forum for clean energy engagement.

In the exhibit hall:
Industry-leading companies displayed next-generation solar, storage, EV charging infrastructure, and manufacturing technologies, spanning hardware, software, and more.
The fifth-annual Solar Games install competition showcased eight talented teams. Huston Solar was named the 2025 Solar Games Champion, taking home the top prize of $10,000, with Sandbox Solar taking second place and Power Northwest Incorporated placing third. Equipment used in the competition was donated to non-profit organization Twende Solar.
The Hub stage, produced with Suncast Media and Solar Builder, featured 30 insightful presentations and interviews by Yotta Energy, ABC Supply, QBi Solutions, PV Magazine's Ryan Kennedy, HEATMAP's Jael Holzman, and more.
The educational program featured industry leaders (including the California Energy Commission's David Hochschild and IREC's Maria Robinson) and technical experts (including National Renewable Energy Laboratory's Emily Dalecki and SEMA Coalition's Rob Gardner) who shared insights on topics ranging from supply chain resilience, AI, and manufacturing innovation to policy frameworks and emerging market opportunities.
The New Product Showcase sustainably highlighted innovations by select exhibitors. Event participants voted electronically, and Emtel Energy USA was announced the 2025 winner.
The Solar Battle of the Bands, the Official After Party of ESNA, was a sold-out success and a powerful fundraiser. Co-hosted with and benefiting the California Solar + Storage Association (CALSSA), the event brought the industry together for an unforgettable night of music, celebration, and community support. Cosmic IX, featuring members of PearlX and special guests, claimed the top spot. Sponsors who made the event possible included: Greentech Renewables, K2 Systems, Mission Solar Energy, PearlX, REC Solar, and Sunnova.
