The short version

  • Each has a real cost: ETAP no pricing is published, and reaching a figure requires completing a multi step quote form; Helioscope licences are single user, so each designer needs their own
  • They diverge on capability: ETAP covers Load flow analysis, Helioscope covers PV system design.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

ETAP

  • No pricing is published, and reaching a figure requires completing a multi step quote form
  • Subscription durations offered are 3 years and 5 years, so there is no short commitment option
  • Licences are banded by user count rather than sold individually, in brackets of 1, 5 to 15, 15 to 25, 25 to 50 and over 50
  • National and international network licences are priced separately

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
