FAQ

Heliosolve vs the market — frequently asked questions

How does Heliosolve compare to other PV simulation software?

Most solutions only solve one part — design, energy simulation, or financial analysis — and leave you to chain them together manually. Heliosolve brings all three into a single cloud platform: from terrain drawing to the bankable report, without exporting between programs or installing anything.

Does it replace my current production simulation software?

Yes. It covers hourly module-level simulation with P50/P90 scenarios and an auditable report, aligned to the international standard IEC 61724 — and adds terrain design and system sizing in the same workflow, all in the cloud.

What makes Heliosolve different?

It covers the full journey in a single platform — design, energy, and bankability — with research-grade thermal modeling, in the cloud, with nothing to install. The entire workflow lives in one place, from terrain to report.

What level of physical precision does it offer?

Heliosolve uses research-grade physical modeling — 3D shading, cell temperature, and a complete loss cascade — with transparent methodology aligned to the international standard IEC 61724. Every study is auditable, so you can verify assumptions and results step by step.

Is it bankable for lenders?

Every study is fully auditable: hourly module-level production, P50/P75/P90/P99 scenarios, debt sizing (DSCR), and a report that documents assumptions, data sources, and losses — following IEC 61724, so the bank's independent engineer can review it line by line.

Can I migrate without overhauling my entire workflow at once?

Yes. You can start with a single project or one phase of the workflow and expand as you gain confidence. Import your data and export results whenever you want — no lock-in.

Does it run on Mac or in the browser?

Yes. Heliosolve is 100% cloud-based and runs on any device with a browser — Mac, Windows, or Linux — with nothing to install.

Can I import my weather data?

Yes. Automatic download from PVGIS, NSRDB, NASA POWER, and CAMS with one click, or upload your own file (CSV, TMY, EPW, TM2/TM3) and we automatically recognize its origin. For bankability studies we support multiple years of data.
