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
  • LIDAR assisted modelling, shade reports and battery storage modelling all require Premium at $259 a month
  • API access and integrations are Enterprise only, which is priced per project rather than per month
  • Paying monthly rather than annually costs $288 more a year on Basic and $468 on Premium

Wattwatchers EMS

  • Requires hardware installation at each monitoring point, increasing total cost of ownership
  • Built for small to medium portfolios; scaling to large portfolios may present usability challenges
  • Limited to energy monitoring; not a comprehensive building management system
