Pre-engineering automation for utility-scale solar

From site to system.

From site boundary to preliminary engineering package — in one pass.

Everything before detail design, in one project context — so AutoCAD and PVsyst start from real numbers. Built in Germany for EPC and developer teams worldwide.

To Get Started

A week of fragmented pre-engineering. One connected workflow.

Manual GIS & setbacks

Days of parcel work before layout — often in a tool that never talks to yield or economics.

Layout iterations in CAD

Row packing rebuilt by hand when the boundary changes — disconnected from terrain and BOM.

Handoff friction between tools

Layout, terrain, and yield live in different files — CAD and PVsyst start from assumptions instead of a shared package.

PVMath does not replace engineers. It delivers the preliminary engineering package in one pass, so your AutoCAD and PVsyst hours start from real numbers instead of assumptions.

Workflow

One project context. Five modules. One package.

Why PVMath

Engineering-grade screening estimates.
Not a bankable study.

Industry-standard datasets. Screening-grade speed. Honest limits built in — and handoff into the tools you already run.

Industry-Standard Solar Data

PVGIS (EC JRC) GHI and irradiation — used in bankable pre-feasibility worldwide.

Region-Routed Terrain Data

Best available public DEM per region — Copernicus EEA-10 (Europe), USGS 3DEP (USA), GLO-30 (global) — resampled to a 5 m layout grid.

CAD Software Ready

Layout DXF and LandXML terrain with parcel linework — UTM-georeferenced or local-origin. No manual redraw from KMZ.

Unified engineering package

PDF, BOM, PVsyst input file, and project ZIP on paid plans — screening, terrain, yield, and economics for go/no-go calls.

IEC string & cable sizing

Electrical screening with rated sizing — not a rough sketch.

Tracker layout you can hand off

SAT and Fixed Tilt auto-layout with BOM, DXF, and electrical screening — ready for CAD and FEED handoff.

Screening-grade only. Not bankable yield, not LiDAR, not stamped civil or structural design. Confirm with survey and detail engineering before FEED.

About PVMath

From the field.
Not a desk.

Founded and built by a utility-scale solar engineer — hands-on experience across Fixed Tilt and Single-Axis Tracker ground-mount design, terrain engineering, and EPC project delivery across Europe, LATAM, MENA and North America.

Built for problems that cost project hours — not boardroom features.

Purpose-Built for Solar

Solar site assessment and engineering — not a generic GIS tool.

Global Coverage, European Roots

Built in Germany. Global PVGIS + Copernicus data. Regulatory flags for DE, AT, ES, US, IN, AU, and more.

Shipped, Not Promised

All seven workflow steps are live today. Roadmap driven by working engineers, not feature checklists.

FAQ

Common questions from engineers.

SiteIQ through RevenueIQ — screening, layout, yield, economics, and one unified report.

What does the seven-step workflow cover?

Project setup → SiteIQ → TerrainIQ → LayoutIQ → YieldIQ → RevenueIQ → unified PDF + project ZIP (paid plans or trial). One project context end-to-end — unlimited analyses on paid plans (seat-based).

Is this a bankable study or a substitute for PVsyst / DNV / Aurora?

No. Pre-feasibility go/no-go only. YieldIQ is intended for early-stage screening; validate with a detailed PVsyst or bankable energy assessment before investment decisions. RevenueIQ uses indicative CAPEX and tariff bands — not investment advice. TerrainIQ uses public DEM, not LiDAR. LayoutIQ is a screening layout, not construction-ready detail design.

What does LayoutIQ produce?

Pitch/GCR sweep, DC capacity, and BOM for fixed tilt (1P–4P) or single-axis tracker (1P/2P). GIS setbacks, layout DXF, optional A1 electrical drawing, and a PVsyst input file for import into PVsyst.

What does RevenueIQ show?

Ten-line CAPEX breakdown, tariff revenue bands, OPEX, LCOE, IRR, NPV, payback, and sensitivity — country-aware auction/PPA modes. Feeds the PVMath site score. Screening only; engage a financial advisor before financial close.

Can I use TerrainIQ exports in CAD?

Yes — for early layout. UTM LandXML surface and georeferenced DXF contours from your boundary. Public DEM screening grade — commission LiDAR before FEED and pile design.

What is in the Step 7 report?

Subscribed plans only: one PDF with all modules, PVMath site rating, and grouped next steps. Project ZIP includes layout DXF, terrain LandXML, BOM CSV, A1 layout sheet, and unified screening PDF.

How is the PVMath score calculated?

A weighted composite (0–100) from module factor scores: grid/regulatory, terrain, energy yield, land use, flood risk, and solar resource. With RevenueIQ, economic viability adds a seventh factor (~20%). Challenging terrain can cap the overall score. Verdict bands run Excellent ≥90 through Critical <45 — see the score breakdown table in your report.

Where is my project data stored, and who can access it?

Saved projects live in Supabase in Zurich, Switzerland (eu-central-2) — a jurisdiction the EU Commission recognizes as GDPR-adequate. In the app, only your named account (and teammates you explicitly invite) can open those projects. We do not sell project data or use it for advertising. PVMath operators can access the database solely for support, billing activation, and abuse handling. Analysis runs briefly on our API; public solar/terrain/map services receive coordinates only, not your full project package. You own your inputs and exports. Full detail: Privacy Policy.
