SAN DIEGO & PORTLAND, Maine--(BUSINESS WIRE)--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.
