The differences that matter most
They differ most on price published. Arka 360 publishes USD 159; RatedPower (pvDesign) publishes Not publicly disclosed. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 24 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
Arka 360 is priced per-seat and RatedPower (pvDesign) 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.

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.
Residential and small-commercial installers who want design, shading, proposal and a light CRM in one subscription, and who are willing to buy permit plan sets from the same vendor. It is not for anyone who needs a dependable list price: the `/pricing` URL alone serves four incompatible price schedules in two currencies in a single page, and `/pricing-in` serves two different rupee schedules simultaneously. It is also not a utility-scale tool — there is no tracker or terrain workflow beyond a "single axis tracker" row in a feature table. [✓ https://arka360.com/pricing · 2026-09-25]
Full Arka 360 profileFor 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.
