Verified against the vendor’s own pages.
Pricing
These cannot be compared on a single number
HELIOS 3D is priced quote-only and Reslink Energy 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 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.
Full HELIOS 3D profileConsider Reslink Energy if…
- you need a price you can plan against before talking to sales
- your systems fit within 100 kW / 500 kW / 5 MW / 100 MW
- your work is mostly residential
Indian rooftop and C&I EPCs whose sales reps carry a phone rather than a laptop and who want the design, BOM and proposal produced on the roof. It is not for anyone who needs a price they can rely on before they call sales: the same site publishes four mutually incompatible price schedules, in two currencies, on two billing periods, with two different sets of plan names — and a fifth figure appears on its Capterra listing.
