Where each one falls short

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

Helioscope

  • Licences are single user, so each designer needs their own
  • Projects are capped at 10 a month on both Basic and Pro
  • System size is capped by plan, at 1.25 MW DC on Basic and 5 MW on Pro, so a larger array forces an upgrade regardless of project count
  • Trackers, LIDAR modelling and API access sit on the higher tiers
  • Enterprise is priced per project with no published figure
