On behalf of the team at SEIA, we want to express our sincere thanks to the sponsors and delegates who attended our 2025 Solar Installers Annual Meetings.

This year we sold out almost every show and caught up with almost six hundred solar installers in Queensland, New South Wales, South Australia, Western Australia and Tasmania between February and May. As one installer said “This is the single most valuable installer event of the year”

The shows may be over, but our committee is already working on the issues and suggestions raised at each event, so you’ll hear more from us over the coming months.

Making SEIA events super affordable and value packed is only possible because of our generous event sponsors, so special thanks to all of them!
