The differences that matter most
They differ most on price published. RatedPower (pvDesign) publishes Not publicly disclosed; 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
RatedPower (pvDesign) is priced quote-only 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.
For developers, IPPs, EPCs and engineering firms who need to iterate hundreds of utility-scale layouts and carry them through to interconnection and off-taker-ready detailed engineering. Not for anyone who needs a published price (all three tiers are "Talk to sales"), not for rooftop or residential, and not for buyers who need site prospecting outside the specific geographies where Enverus PRISM International data is licensed.
Full RatedPower (pvDesign) 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.
