The differences that matter most
They differ most on price published. HELIOS 3D publishes Not publicly disclosed; PV*SOL premium publishes EUR 845. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 23 differences drawn from the same sourced dataset that powers both product pages.
Verified against the vendor’s own pages.
These cannot be compared on a single number
HELIOS 3D is priced quote-only and PV*SOL premium is priced per-seat. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.

Scroll the table sideways to see both products. The capability column stays in place.
Framed as requirements, not a verdict. Both descriptions come from the same data.
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.
Full HELIOS 3D profileFor European installers, planners, roofers and energy consultants doing residential and commercial rooftop work where realistic 3D shading, battery/EV/heat-pump self-consumption and a presentable customer report matter. Not for utility-scale ground-mount engineering (the published ceiling is 7,500 mounted / 10,000 roof-parallel modules), not for macOS, and not for anyone needing a cloud or multi-user workspace.

They differ most on price published. In total we recorded 23 verified differences and 9 points where they are the same.
HELIOS 3D is priced quote-only and PV*SOL premium is priced per-seat. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.
We do not name a winner. Both are described from the same verified data, and which suits you depends on your requirements — the differences above are the facts; the choice is yours.
