Easy PV or HELIOS 3D?
They differ most on price published. Easy PV publishes GBP 0; HELIOS 3D publishes Not publicly disclosed. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 35 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
Easy PV is priced per-seat and HELIOS 3D is priced quote-only. 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 Easy PV if…
- you need a price you can plan against before talking to sales
- you want to start without a budget approval
- your work is mostly residential
UK residential and light-commercial installers who already buy from Midsummer, need MCS-compliant self-consumption modelling and structural/wind-loading numbers, and want DNO paperwork handled in the same place as the design. It is not for anyone outside the UK — MCS, DNO and the Midsummer trade account are the whole point — and the free tier's commercial logic should be read plainly: the software is free because the distributor is selling the hardware.

Full Easy PV 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.
