Frequently asked
Are these calculators free to use without a Sunhub account?
These pages explain planning inputs and purchasing considerations. Check the linked tool for current access requirements and available functions; a planning guide is not a live calculator.
Do the tools pull pricing from live marketplace listings?
Yes. The calculators price against live Sunhub catalog data rather than a static spreadsheet, so an ROI or BoM estimate reflects current marketplace pricing instead of stale numbers. That is what lets you quote off real figures and not guesses.
Can a BoM built in these tools convert directly into an RFQ?
Yes. A bill of materials built in the BoM Builder is designed to carry straight into an RFQ or order rather than being re-keyed, so you move from tool output into a quote without rebuilding the list. That keeps the parts, quantities, and live pricing intact through the handoff.
