There aren't necessarily requirements for being able to host a panel. All you would need to do is sign up for a panel when the submission form goes up.
Since con just ended, there are no dates set in stone for any of this yet, but the form traditionally goes up around January and goes through the beginning of June, with notification as to whether your panel was accepted or declined being sent late June to early July.
If you have any questions regarding panels, you can always email the Panels Staff at panels@kumoricon.org for more info as well. We're also looking to get an updated guide or FAQ about submitting and hosting panels at Kumoricon for the 2015 year, which would be up around the time sign ups start.
