Frequently asked questions

Can I upgrade from Free to Pro without losing my projects?

Yes. Your account stays the same — upgrading unlocks the P10/P90 bands, the financial model and the exports. Everything you configured on Free stays in place.

What does "calibration to a bankable report" mean?

If you already have a formal energy yield report (PVsyst, RatedPower), Voltaraj adjusts the annual yield to match the exact figure in that report, while preserving the hourly physical shape of production. The result: a financial model built on the number your lender already recognises.

How does the on-prem option for banks work?

The platform runs on your servers. The financial engine receives only configuration objects and revenue figures, and returns DSCR / IRR / NPV — it never touches or sees the raw market data warehouse. Your data never leaves the institution's perimeter.

Is the €1,500 report the same as what the Pro subscription generates?

Yes, it's exactly the same deliverable. If you need more than two reports per year, the Pro subscription becomes mathematically the better deal — and you can expense it from your first financed project.

Which market does Voltaraj cover?

Coupled European spot markets — Romania, Bulgaria and Hungary live. Prices come entirely from the ENTSO-E Transparency Platform (as reported by the market operator) — a source with commercial re-use rights — in each market's own currency, converted to RON at the official central bank rate for Romania. No scraped data, no negotiated licensing dependencies. Financial modelling currently runs on the Romanian price series.

Can I pay by card and get a proper invoice?

Yes. Payment is by card, and a fiscal invoice is issued automatically and submitted to the national e-invoicing system. No paperwork on your side.
