Where each one falls short

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

OATI webOASIS

  • The Internet Archive's capture of OATI's homepage on 20 December 2020 named webOASIS-related modules (OASIS, OASIS Management, OASIS Automation) among dozens of grid and energy trading products, all sold enterprise-to-enterprise via login/contact with no price figure published.

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
