Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aurora Solar

  • Both published plans are single user, so a second designer means a second licence
  • Projects are capped at 50 a month on both Basic and Premium, so the tiers differ on features rather than volume

  • The number of concurrent users on the Multi-User Edition is limited to the number of licences purchased
  • A floating licence used on a local machine is time limited to a maximum of 30 days
