DNV SolarFarmer or HelioScope?
They differ most on price published. DNV SolarFarmer publishes Not publicly disclosed; HelioScope publishes USD 159. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 28 differences drawn from the same sourced dataset that powers both product pages.
Verified against the vendor’s own pages.
Pricing
These cannot be compared on a single number
DNV SolarFarmer is priced quote-only and HelioScope is priced capacity-tiered. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.

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 HelioScope if…
- your systems fit within 1.25 MW DC (Basic) / 5 MW (Pro) / 30 MW (Enterprise)
- AI-assisted workflows matter to you
For C&I designers and engineers who need a layout, a bankable-grade production estimate and a sales proposal without leaving one tool. Not for residential one-roof sales work (the same vendor routes that to Aurora) and not for jobs above 30 MW DC — the vendor publishes a hard design-size cap on every tier.
