Which might suit you

Framed as requirements, not a verdict. Both descriptions come from the same data.

Consider HELIOS 3D if…

  • you work at utility scale

For utility-scale project developers, EPCs and engineering firms that already own a Civil 3D estate, have IT able to run and back up a SQL Server instance, and need a layout that survives into earthworks and pile-driving coordinates. Not for anyone who wants a browser tool, a price they can read, a trial they can self-serve, a rooftop or residential workflow, or a licence that survives losing a USB stick — the vendor's own help centre says losing the dongle "will result in the irrevocable loss of your license" and recommends buying electronics insurance.

Consider RatedPower (pvDesign) if…

  • AI-assisted workflows matter to you
  • you work at utility scale

For developers, IPPs, EPCs and engineering firms who need to iterate hundreds of utility-scale layouts and carry them through to interconnection and off-taker-ready detailed engineering. Not for anyone who needs a published price (all three tiers are "Talk to sales"), not for rooftop or residential, and not for buyers who need site prospecting outside the specific geographies where Enverus PRISM International data is licensed.
