The differences that matter most
They differ most on price published. Enact publishes USD 279; SolarEdge Designer publishes Free. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 25 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
Enact is priced per-seat 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.

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.
Installers who want one vendor for sales design, permit-grade engineering and post-install monitoring, and who will pay for those as three separate line items. It is not a single unified product: the "end-to-end platform" announced in January 2026 is, as sold on 2026-09-25, three priced modules — one of which still lives on a separate domain under a separate brand, with its own pricing pages that disagree with Enact's. [✓ https://enact.solar/providers/provider-pricing/ · 2026-09-25]
Full Enact 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 25 verified differences and 12 points where they are the same.
Enact is priced per-seat 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
