From site to bankable report

Without weeks of rework between tools.

Design, energy and bankability in a single workflow. No exports, no manual rework.

Our engine, validated against sector references

Heliosolve in action

Model your utility-scale plant in the browser

Define geometry, modules, inverters and losses, and simulate production with nothing to install. In minutes, not weeks.

P50/P90 with statistical rigor

Thousands of iterations to quantify resource and production uncertainty. A P50/P90 built to bankable criteria, not an optimistic guess.

From model to bankable report in one click

Export bank-grade technical documentation: P50/P90, loss analysis, sensitivities and executive summary. No manual assembly.

FAQ

Objections

Does it replace my current simulation software?

Yes, and it does much more. Today you use one program to simulate, another to design, and another for financial analysis — losing time passing data between them. Heliosolve brings everything together in one place, inside your browser: draw the terrain, calculate how much energy the plant will produce every hour of the year — accounting for shading, temperature, and all real losses — and generate the bankable report, without switching tools or installing anything. All following the international industry standard (IEC 61724) and with the production scenarios (P50/P90) that lenders require.

Is it bankable for lenders?

Yes. Heliosolve generates a complete and transparent report — the type that banks and their engineers review before financing a project. It calculates expected production across multiple scenarios (P50, P75, P90, and P99), estimates how much debt the project can support, and fully documents everything: the assumptions used, where the climate data comes from, and how each loss was calculated. It follows the international standard IEC 61724, so any external reviewer can verify it step by step.

Can I import my weather data?

Yes, and it's straightforward. With a single click, Heliosolve downloads climate data from the most recognized industry sources (PVGIS, NSRDB, NASA POWER, and CAMS). If you already have your own data from any common provider, simply upload it and the platform automatically recognizes its origin. For the bankability study you can use multiple years of data, as required by a rigorous solar resource analysis.

Is my data secure?

Yes, completely. Each company's information is isolated: only you and your team can see your projects — no one else. We use encrypted connections, protected passwords, log every activity, and apply the same security measures expected from a professional platform. Your projects are yours: you can download them at any time and take them with you, no questions asked.

What happens to my projects if I stop paying?

Your projects, designs, and reports are yours and you can download them at any time. We don't hold your data hostage or lock you in: if you ever decide to leave, you take everything with you.

How long until I have my first study?

You can go from drawing the terrain to a bank-ready report in a single session, with nothing to install. A plant of over 10 MW simulates in minutes, so you can test different design ideas in the same day — instead of waiting days passing information between programs.
