The differences that matter most
They differ most on price published. HelioScope publishes USD 159; SolarEdge Designer publishes Free. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 21 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
HelioScope is priced capacity-tiered and SolarEdge Designer is priced free. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.

Prices are shown exactly as each vendor writes them and are never converted between currencies.
21 differences, ordered by how much they are likely to matter — pricing transparency first, then capabilities the vendor explicitly confirms or denies.

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 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.
Full HelioScope profileFor installers designing SolarEdge systems who want design, compliance checking and a proposal at no cost, integrated with the SolarEdge Monitoring Platform. Not for vendor-neutral design work: the vendor's own copy scopes it to "all your SolarEdge systems" and to compliance with "the latest SolarEdge design rules". Any comparison page must state that the price is zero because the product sells inverters, not software.

They differ most on price published. In total we recorded 21 verified differences and 15 points where they are the same.
HelioScope is priced capacity-tiered and SolarEdge Designer is priced free. 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.

This comparison is generated from the feature database, not written by hand. A pair is only published when the data holds at least five stateable differences — which is why 281 candidate pairs were refused. How comparisons are built
