The short version

  • Only Helioscope has a free tier, so it costs nothing to try first.
  • Each has a real cost: Helioscope licences are single user, so each designer needs their own; Landis+Gyr Gridstream the platform depends on Landis+Gyr metering hardware, including electric, gas and water meters plus communication network devices, rather than being sold as software alone
  • They diverge on capability: Helioscope covers PV system design, Landis+Gyr Gridstream covers Advanced metering infrastructure.

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

Landis+Gyr Gridstream

  • The platform depends on Landis+Gyr metering hardware, including electric, gas and water meters plus communication network devices, rather than being sold as software alone
  • No price, licensing model or subscription term is published on the solutions pages; the site offers only a contact form and a distributor finder
  • Deployment, integration and ongoing optimisation are sold as separate Lifecycle Services rather than included
