Which might suit you
Framed as requirements, not a verdict. Both descriptions come from the same data.
Consider DNV SolarFarmer if…
- you are comfortable with desktop software and its constraints
- you work at utility scale
For yield engineers and IEs at developers, lenders and EPCs who want a model backed by an assurance firm's operational dataset and are comfortable in a scripted desktop tool. Not for rooftop, residential or C&I sales work, not for macOS, and not for anyone who needs to see a price before talking to someone — the "View pricing" link leads to a JavaScript storefront that serves no product content to a non-JS reader.
Full DNV SolarFarmer profileConsider 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.
