2025’s Top Solar Events to Attend
Your 2025 Solar Event Roadmap
By the Editors of Solar Business Insider
When we reflected on our biggest wins as a team at Solar Business Insider, one thing stood out: events.
Over the last two decades, the connections, deals, and projects that truly moved the needle all started with a handshake at a conference or a chance encounter at a networking event. We didn’t plan for these introductions—they happened by showing up, being open, and building genuine relationships.
That’s why we’re convinced that attending the right events can transform your business. Whether it’s discovering new ideas, meeting future partners, or learning from the best in the industry, these moments are more than just opportunities—they’re catalysts.
In that spirit, here are the top five solar events to check out for the rest of 2025.
Note: Since this is our debut issue in late February, we’re focusing exclusively on the top solar events still to come in 2025.
