Which might suit you
Framed as requirements, not a verdict. Both descriptions come from the same data.
Consider Reslink Energy if…
- you need a price you can plan against before talking to sales
- your systems fit within 100 kW / 500 kW / 5 MW / 100 MW
- your work is mostly residential
Indian rooftop and C&I EPCs whose sales reps carry a phone rather than a laptop and who want the design, BOM and proposal produced on the roof. It is not for anyone who needs a price they can rely on before they call sales: the same site publishes four mutually incompatible price schedules, in two currencies, on two billing periods, with two different sets of plan names — and a fifth figure appears on its Capterra listing.

Full Reslink Energy profileConsider SAM (System Advisor Model) if…
- you need a price you can plan against before talking to sales
- you want to start without a budget approval
- you are comfortable with desktop software and its constraints
- you work at utility scale
- your work is mostly residential
For analysts, researchers, policy people and developers who need a transparent, auditable, free model and a real financial structure behind the kWh. Not for installers who need a roof capture, a proposal or a plan set — SAM has no satellite imagery workflow, no proposal output and no CRM, and it registers users with a free software key rather than selling a licence.
