Pricing
These cannot be compared on a single number
Arka 360 is priced per-seat and PlantPredict is priced on an unrecorded basis. 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 Arka 360 if…
- you need a price you can plan against before talking to sales
- AI-assisted workflows matter to you
- your work is mostly residential
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 profileConsider PlantPredict if…
- you work at utility scale
For utility-scale energy modellers and IEs who want a browser tool with unlimited projects, a documented algorithm set their lender's IE can audit, and automation. **Not for residential or C&I rooftop sales work, not for** teams that need layout-to-construction CAD (Design Pro is GIS-based, not an AutoCAD product), and not for anyone taking the site's structured data at face value — its schema publishes a price that its own pricing page contradicts.
