Which might suit you
Framed as requirements, not a verdict. Both descriptions come from the same data.
Consider HelioScope if…
- your systems fit within 1.25 MW DC (Basic) / 5 MW (Pro) / 30 MW (Enterprise)
- AI-assisted workflows matter to you
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 profileConsider RatedPower (pvDesign) if…
- AI-assisted workflows matter to you
- you work at utility scale
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.
